ANDRENA (OLIGANDRENA) ANGELESIA, new species 



As in other members of the Oligandrena group, the hair of 

 the propodeum in this species is very short and not corbiculate. 

 The flocculus of hind trochanters is also short and straight. From 

 A. macrocephala Cockerell and A. nigroclypeata Linsley, the fe- 

 male of angelesia differs in having only a trace of blackish hairs. 

 The male has the head more transverse than in macrocephala, 

 with broader, more angulate cheeks, the mandibles more slender 

 and gently curved, the clypeus only partially yellow, and the third 

 antennal joint little longer than the fourth. 



Female. — Black, the small joints of tarsi ferruginous, the man- 

 dibles and malar space a little reddened, the flagellum more or 

 less reddish brown toward apex, and the spurs brownish testa- 

 ceous. Tegulae dull ferruginous. Wings dusky hyaline, the ner- 

 vures fuscous, the stigma with a reddish central streak. Labrum 

 short and transverse, its apical margin gently curved and sharply 

 margined. Basal process of labrum low, very broad, and rounded. 

 Disk of labrum transversely grooved beyond the process. Malar 

 space short and transverse. Facial foveae broad and ending at 

 level of top of clypeus. Antennal joint 3 nearly as long as the 

 next three joints together. Head dull, minutely tessellate, the 

 clypeus, especially toward apical middle, more shining, and 

 closely and shallowly punctured, the punctures fainter toward 

 the margins. Frons closely and rather obscurely striate. Thorax 

 minutely granular-tessellate, opaque and impunctate, becoming 

 a little shining on sternum, sides of propodeum, and basal area, 

 which lack the granulation. Basal area small and triangular. 

 Abdomen tessellate, moderately shining, and impunctate except 

 for excessively minute setigerous punctures. Pubescence mod- 

 erately dense, bright or reddish fulvous on the vertex, mesonotum 

 and metanotum, and dull whitish elsewhere on head and thorax.
