New and Little Known Bees From 

 California 



By T. D. A. COCKERELL 



The bees described and listed below are from the Baker collection, 

 and were kindly transmitted to me by Professor Wm. A. Hilton. 

 All are from Claremont or the vicinity. 



Glossoperdita gen. nov. 

 Like Perdita Smith in general structure and appearance, but 

 mouth-parts enormously elongated, apparently not retractile, the 

 end of the tongue reaching beyond tip of abdomen; maxillary palpi 

 6-jointed, slender and very short, about 300 microns long; maxillary 

 palpi about 1280 microns from base of mouth-parts, the blade ex- 

 tending about 3200 beyond the palpi, but the labial palpi not cor- 

 respondingly elongated, their encis only about 800 microns beyond 

 insertion of maxillary palpi. Head narrow, facial quadrangle con- 

 spicuously longer than broad; facial foveas elongate and deep, end- 

 ing below about level of insertion of antennae; b. n. falling far short 

 of t. m.; second s. m. very broad (long) but much narrowed above; 

 stigma small and narrow; marginal cell long for the group, broadly 

 truncate at end. 



Glossoperdita pelargoides sp. n.

 white; head and thorax blue-green, but the mesothorax only green in 

 front, the greater part, as well as the scutellum, black; clypeus and 

 supraclypeal area black, sparsely and distinctly punctured; the face 

 apparently without light markings, but close inspection shows a 

 broad shadowy pallescent band in middle of clypeus, and similar 

 triangular pallescent lateral marks, hardly visible; flagellum bright 

 ferruginous beneath except basally; front dull; mesothorax shining 

 anteriorly, the median groove deep; pleura polished, shining; tuber- 

 cles pale reddish, two small pale marks on upper border of pro- 

 thorax; legs piceous, hairy, anterior knees and band on tibia pale 

 yellowish, middle knees pale reddish; tegula? redciish ; wings short,
