30 Descriptions and Records of Bees. 



tliorax, or legs, but with very pale yellowish (ivory-coloured) 

 Lands, very slightly interrupted in the middle, on the first 

 five abdominal segments ; spurs dark. Wings infuscated, 

 violactous in the marginal cell and beyond, outer marginal 

 field witii crimson and green irilesconce. 



This looks almost exactly like Microsteh's foederah's (Smith), 

 but differs in several important characters, as follows: — 

 Second recurrent nervure meeting second transverse cubital; 

 apex of third ventral segment with a median, oval, shining, 

 button-like tubercle ; band on first abdominal segment 

 scarcely or not interrupted ; flagellum entirely black. 



Hab. Lee County, Texas, April 10, at flowers o£ Fhacelia ; 

 collected by the Rev, G. Birkraann. 



Osmta hotitena, sp. n. 



? . — Length about 9 mm. 



Rather robust, bluish green ; head and thorax densely 

 punctured, abdomen less densely; clypeus normal, rather 

 projecting ; mandibles 3-dentate ; antennae and tegulge black. 

 Wings broadly pale reddish smoky in marginal cell and on 

 outer margin. Legs black, more or less tinged with blue- 

 green, the anterior femora behind brilliantly coloured; hair 

 on inner side of hind basitarsus pale orange ; hair of head 

 and thorax white; abdomen subfasciate, with white hair at 

 sides of first two segments ; ventral scopa yellowish white. 



Closely related in all respects to 0. suhfasciata, Cresson 

 (which I have from Piano, Texas, collected in June by 

 Mr. E. S. Tucker), but the abdomen is conspicuously broader 

 and the punctures on the posterior segments are not large and 

 coarse as they are in suhfasciata. In both the basal nervure 

 falls a trifle short of the transverso-medial. The iiead in 

 0. hotitena is somewhat broader than long ; in suhfasciata the 

 reverse is the case. Compared with 0. conjuncta, Cresson, 

 the new species is larger and much greener, with the abdomen 

 longer and more strongly punctured. Compared with 

 0. jyuniila it is larger, more brightly coloured, and has the 

 second and third abdominal segments conspicuously con- 

 stricted near the base, which is not at all the case in pumila. 



Hah. Lee County, Texas, April 23, 1906 {Birkraann^ 

 no. 99). 



The name hotitena (from the Malay) has reference to the 

 white ventral scopa.
