Reprinted from 1/Je ] OUJI.NAL OF TH E K ANSAS ENTO MOT.OCICAI. S OCIETY Vol. 27, January , 1954, No . I A GENUS OF BEES NEW TO THE ILLINOIS REGION 1 CHARLE S D. MICH ENER Lawr ence, Kansas In a box of bees sent me by Dr. C. L. Remington of Yale University are three specime ns of Lithurg e bruesi Mitchell, 1927, from Jersey County, Illinoi s. This is a remarkable record, as the species was hitherto known only from Texas, and the only parts of the midwest from which any species of Lithurge has been recorded are the plains states (Kansas , Nebraska, South Dakota). In North America the genus is widesp read in the west and evi-dently occurs across the Gu lf States to Florida and orth Caro lina. Our species of Lithurg e appear to be entirely dependent upon cactus (Opuntia and its relatives) for pollen. It is therefore not surprising to find them rare in the whole northeastern part of the count ry where cacti are rare or absent . The following are new records for Lithurge bme si Mitche ll, based pri-marily upon specimens in the Snow Entomolog ical Museum: Illinoi s: Principia College, Elsah, Jersey Cou nty, June 5, 1942 (C. L. Remington). Texas: Quemada , Apri l 11, 1950, on Opuntia (Michener , Rozens, Beam-ers, Stephen); 18 miles north of Harlingen , Apri l 2, 1946, on Opuntia (C. D. Michene r); 45 miles south of Sonora , Apri l 10, 1950 (Beamers, Stephe n, Michener , Rozens); Big Bend, June 23, 1947 (R. E. Eibel) ; 22 miles south of Laredo, April 15, 1952 (Michener , Wi lle, La Berge, Beamers) ; Bishop, Apr il 17, 1952 (Michener , Wille , La Berge, Beamers) ; Lopeno, Apri l 16, 1952 ( Michener, Beamers , Wille , La Berge, Beamers); Uva lde, April 14, 1952 (Michene r, Beamers, Wille , La Berge) ; 10 miles north of Rockport, Apr il 18, 1952 (Mic hener, Beamers, Wi lle, La Berge). From the above it is evident that this is a common and widespread species in Texas. It should be pointed out that the diagnostic character of the female ment ioned by Mitchell in his review of the genus (Psyche , vol. 45, pp . 146-155, 1938) is incorrectly stated in that paper. The structure having a small med ian emargination and a deeper emargination on each side is the basal ele-vation of the labrum , not the apical margin of the clypeus. 1 Contri buti on o. 44, Departm ent of Entomology, Uni ver ity of Kansas.
