TWO NEW SPECIES OF OSBORNELLUSDWIGHT M. DELONG AND LAWRENCE BEERY,The Ohio State University, Columbus, OhioOsboraellus filamenta n. sp.Resembling cons or s in general appearance, but darker; slightlysmaller and with genitalia quite similar to borealis. Length, male,4.2 mm.; female, 4.5 mm.Vertex not as sharply angled as in consors, as long as basal widthbetween eyes.Color: Similar to consors but much darker. Vertex dark withblack markings. Pronotum and scutellum finely mottled dark grayand brown. Elytra clear, veins dark brown. Costal anteapicalveinlets and inner ends of claval veins, broadly brown. Central areaof cells on disc and second and anteapical cells with elongate brown spots.Genitalia: In general quite similar to borealis. Male plates nar-rowed to form slender attenuate tips. Styles broad at base, graduallynarrowing to slender caudally directed apical portion. Oedaguscomposed of a rather short dorsal portion below which is a longfilamentous, caudally directed process and below this a pair of long,tapered filamentous processes, which are directed caudally. Apicesof processes differing distinctly from those of borealis, which are angledventrally and abruptly narrowed at apex.Described from one male collected at Davis Mts., Texas, Aug. 22,1936, and one female from the same place, July 6, 1936, by J. N. Knull.Holotype male and allotype female in collection of senior author.Osboraellus knulli n. sp.Resembling consors in size and general appearance. Genitalia verydistinct. Length, 5.5-6 mm.Vertex about as long as basal width between the eyes.Color: Similar to consors but lacking the distinct markings ofvertex and pronotum. Vertex pale with black line along apex, posteriormargin white. Pronotum grayish with black markings on anteriormargin. Elytra subhyaline, veins brown. Inner ends of claval veinsand costal anteapical veinlets, broadly dark brown. Central area ofcells on disc and on second and third anteapicals, brown.Genitalia: Male plates narrowed to form attenuate apical halfwhich is slightly broadened before slender apices. Styles broad atbase, narrowing to slender caudally directed apical half. Oedaguscomposed of a dorsal portion and a pair of broad ventral processes whichin ventral view are abruptly narrowed to apices sharply pointed oninner margin. The dorsal process is curved anteriorly on the basalhalf, and caudally on the apical half which is composed of a shortdorsal spur and a much longer, broader, caudally directed processupturned and pointed at apex.Described from two males and one female, all taken in HuachucaMts., Ariz., July 20, 1936, J. N. Knull. Holotype male, allotypefemale and male paratype in collection of senior author.266
