From the ANNALS AND !llAGAZINE 01" NATURAL HISTORY, Ser. 7, Vol. vii., January 1901. Contributions from the New Jfe:cico Biological Station.-IX. On ce1·tain Genera of Bees. By T. D. A. and WILMATTE p. COCKERELL . (l) ANTHOPHORIN.lB. In Trans .Amer. Ent. Soc. xxvi. 1899, pp. 58-64:, Mr. W. H. Ashmead has given tables for the separation of the genera of 47 T. D. A. and W. P. CoQkerell on Bees. this group; but we find these unsatisfactory on account of the stress laid upon minor differences of venation, while certain radical differences in the mouth-parts of the genera are overlooked. This defect was perhaps unavoidable in a synopsis of the genera of the whole world, many of which could not at the time be examined for mouth-characters ; but it may be useful here to indicate the lines on which a better classification may be framed.

The last three genera are separated also by good characters of the venation, for which see the tables of Ashmead and Cresson. Ashmead cites no type for his new genus Empho-ropsis, but in a letter he informs me that it is Habropoda jloridana, Smith. The known species of Emphoropsis are E . .floridanus (Habropoda jloi·idana, Sm.), E. miserabilis (I-I. 1m'serabilis, Cress.), E. Morrisoni (H.1lforrisoni, Cress.), and E. salviarum (H. salviarum, Ckll.). Emplwropsis differs from Habropoda by the relatively long first joint ot' maxillary pal pi and the second not so long as 4 to 6 united; there are also other important differences, duly indicated by Ashmead. ANTH0PH0R0IDES, gen. nov. Type A. vallorum (Podalirius vallorum, Ckll.). Maxillary pal pi 5-j ointed, the second joint long, the last very small. The superficially similar Anthophora Lesquerellm, Ckll., is a true Anthophoi·a. AMEGILL.A,~Friese. Anthophora cleornis, Ckll., and A. cardui, Ckll., belong to 49 T. D. A. and W. P. Cockerell on Bees. this group, which Ashmead treats as a genus. The mouth-parts agree with Antlwphora, and we think Amegilta at best of subgeneric rank. MELITUHGOPSIS, Ashm. Ashmead cites no type, but has kindly sent us the type species, an undescribed form from San Francisco Co., Calif., collected in October. It is superficially just like Anthophora Portera?, Ckll., but differs in venation and other particulars, and is certainly not con generic. ln Cresson 's tables it runs to Habropoda, but Cresson's "Habropoda" is Emphoropsis. '11he second submarginal cell along the cubitus is shorter than the first or third, whereas in E. salviarum and fforidanus it is about equal to the third. The male Meliturgopsis has the scape all black, clypeus white except sides and anterior edge, lateral face-marks V-shaped; hair of thorax greyish white mixed with black; abdomen without bands, first segment densely covered with greyish-white hair. Metiturgopsis seems practically identical with Emphoropsis, the latter having priority of place. E UC ERIN I. Max~llary palp! 4-jo_inted . . . . . . . . . . . . 1.

Eucera, Scop. Three submarginal cells ........ , . Xenoglossa, Smith; Xenogloa-sodes, Ashm. ; Florilegm, Rob.; &c. MACROGLOSSAPIS, Ckll.=Macroglossa, Rads. (not Ochs.). This genus is omitted by Ashmead. It differs from other genera of Anthophorinre by its 3-jointed maxillary palpi; the tongue is as long as the body; antennre filiform, as long as the thorax.

Antliidium, Fabr. PROTANTHIDIUM, gen. nov. Type P. steloides (Megachile steloides, Bingham), of which T. D. A. and W. P. Cockerell on Bees. 50 we have a male from the Rhasi.a Hills, India, sent by Mr. Sladen. The face is yellow below the antennre; scutel-lum prominent and bilobate; abdomen marked on apical segments with yellow. This has the mouth-parts nearly as in Megachile, but the ornaments of an Anthidium. It appears to be the most primitive of the Anthidiinre. ANTHIDIUM, Fabr. Here falls A. mani'catum an<l such American species as A. Porterm and A. maculo.rnm. DrANTIIIDIUM, Ckll. This was rlescrihed as a subge11ufl, but it should probably be regarded as a genmi. Its typ e is D. curvatum (Antltidium curvatum , Smith), and D. parvum (Anthidium pm·vum, Cress.) is quite congeneric. 'l'he little group of D. ,qilense (Ck!!.), D. Elii·lwrni fCkll.), D. notatum (Latr.), D. pr·rp1exum (Smith), an<l D. striyatum (Panz .) *, all described under Antltidium, iB possibly of sub -generic value, and in respect to its labial palpi falls more or less between A nthidz'um an<l flia11thidium. D. gil ense, in particular, falls with Anthid-ium if its mouth alone is regar<led, and so far presents an argument against the generic status of Diantltidium. The following measurements of the first two joints of the Iabinl palpi. are in µ, :-D. strigatum D. gilense . JJ. parvurn D. perpi'ctum A. mani'catum . A. Porterm (1) (1) (1) 650, (2) 870. 7t0, (2) 760. 7t0, (t) 1220. (1) 650, (2) 1200. (1) 1300, (:2) 1320. (1) 1200, (2) 1000. The nesting-habits of Diantliidium and A ntlzidium seem not to be the same; compare D. consimile (Ent.News, 18967 p. 25) with Anthidium rnanicatum antj A. paroselm. PARANTHJDIUM, subgen. nov. TypeDianthidiumperpictum (Antlzidiumperpictum, Ckll.). This has the primitive character of 3-jointed mnxillary palpi but the venation of Dianthidi·um. ' East Las Vegas, New Mexico, U.S.A., October 29, ll!00. * vVe have this species from Mar seilles, France, sent by M. Erne st Andre. It seems that, according to the law of priority, it ought to be called D. minus (Ap£s maculata, var. minor, Russi, 1790) .
