NEW BEES OF THE GENUS COLLETES. 



BV MYRON H. SWENK, LINCOLN, NEBRASKA. 



CoUetes clypeonitejis, n. sp. — 9. Length 11 mm. Clypeus promi- 

 nent, polished, narrowly medially sulcate, its punctures coarse but scat- 

 tered and not forming stria?, its apex slightly emarginate and preceded by 

 a transverse rim. Malar space one and one-half times as long as broad, 

 finely striate. Antennae black, the flagellum brownish beneath, joint 3 

 decidedly longer than 4. Face dull, finely and feebly punctured, its 



pubescence dense and erect, dull soiled gray, becoming whitish about 

 clypeus. Vertex shiny, minutely punctured. Cheeks dull, striate like 

 malar space, with long white hair and short appressed pile about orbits. 

 Prothorax without an apparent spine. Punctures of mesothorax small and 

 widely separated, a very large polished disk subimpunctate. Scutellum 

 finely separately punctured, these closest along posterior border. Post- 

 scutellum finely densely punctured. Pits on superior face of metathorax 

 very irregular and poorly defined, apparently very long and narrow, medially 

 on a broadened area. Enclosure funnel-shaped, polished, smooth, the bowl 

 convex. Pleura shining, with fine, well separated punctures. Pubescence 

 of thoracic dorsum dull yellowish gray, whitish on pleura, metathorax, 

 postscutellum and below. Tegulae yellowish testaceous. Wings clear, 

 nervures and stigma dark brown, the former becoming yellowish at base, 

 with the costal nervure entirely yellow. Abdomen parallel-sided, first seg- 

 ment shining, finely, rather indistinctly, scatteringly punctured, following 

 segments finely, closely, indistinctly punctured. Tergum with a fine, very 

 dense, short and appressed pile practically concealing the surface between 

 the contrasting, very dense, shaggy fasciae, all of a dull gray colour, basal 

 segment with long white hairs, segments ^,-6 with white bristles, 6 bare of 

 appressed pile. Venter shining, not banded. Legs black, with white pub- 

 escence, that on posterior femora and tibiae very long and quite dense, carry- 

 ing much pollen, outer tibial spur not pectinate, both spurs short and yellow, 

 claws rufous, with the inner tooth submedian, front coxae without spines. 



Type. — Los Angeles, California (Dr. Davidson), i ^ specimen. 



There is no other species known to me, except the following, which 

 shows close relationship to this one, which is very distinct in its sparsely 

 punctured, non-striate clypeus, long malar space and denselypilose tergum. 

 On the whole its nearest relative is probably C. delodoiitus, Viereck, or C. 

 ^Ibescens^ Cresson.
