New Californian Bees 



By T. D. A. COCKERELL 



In a small collection of bees recently received from Pomona 

 College, I find four new species, which are described herewith. 



Ti'trdloiiici ponio)id' sp. n. 



$ Length 10 mm., black with the clypeus pale lemon yellow, 

 notched at sicies; labrum pale yellow, but mandibles entirely black; 

 antennee black, flagellum reaching end of second abciominal seg- 

 ment; thirci antennal joint a little longer than broad; eyes (ciry) 

 very dark brown; face broad, covered with long dull white hair; 

 thorax above with very pale ochreous hair; ciisc of mesothorax 

 brilliantly shining, feebly and sparsely punctured; tegulae fuscous 

 with a rufous spot posteriorly; wings dusky hyaline; nervures rufo- 

 piceous; second s. m. narrowed above, receiving first r. n. a little 

 beyond beginning of last third; legs with dull white hair, orange- 

 ferruginous on inner side of tarsi; small joints of tarsi clear ferru- 

 ginous, but basitarsi at most obscurely reddened apically; hind spur 

 normal; abdomen with hind margins of segments narrowly hya- 

 line; first segment with long pale hair; second with thin pale hair 

 basally, but short fuscous hair subapically; third like second, but 

 with a definite basal band of dull white tomentum; fourth covered 

 with dull white tomentum, but a little fuscous hair just before 

 margin; fifth like fourth, except that hind margin has a dense white 

 fringe, and no fuscous; apical plate ferruginous, with fulvous hair 

 on each side. 



Hab. — Laguna, California {R. La FoUette., B 2). In my tables 

 in Trans. Amer. Ent. Soc, 1906, this runs to T. lepida, but it has 

 not the narrow face of that species. It resembles T. birknuuinicUa 

 Ckll. and T. poetica Ckll., but the three are easily separated thus: 

 Flagellum about 12 mm. long, reaching beyond end of third ab- 

 dominal segment; upper margin of clypeus broadly black. 



poetica Ckll. 

 Flagellum 10 mm. or less; upper margin of clypeus not black. 1.
