central raised line. The apical abdominal plate is broadly 

 trui.cate, with rounded corners ; its colour chestnut-red, with 

 the apical margin broadly whitish. 

 $ . — Length about 6^ mm. 



Similar to the male except for the usual sexual differences; 

 flagellum ferruginous beneath except at base (in the male it 

 is dark) ; hind margins of abdominal segments pale testa- 

 ceous ; third antennal joint as long as the next three com- 

 bined ; clypeus densely covered with shining white hair ; 

 facial fovea} linear, black. The hind legs are covered with 

 white hair, but it hardly seems to amount to a polleniferous 

 scopa (no pollen has been collected), and there is no curled 

 basal floccus. 



Can the insect be parasitic? The female is totally distinct 

 from D. nothocaUddis and D. chalybcea by its small size, lack 

 of black hair, &c. The tirst abdominal segment is shining in 

 the female, dull in the male. In both sexes the process of 

 labium is bituberculate.

The specific name, from the Malay, means white-haired. 

 Judging from appearance, this seems to be a species which 

 has adopted parasitic habits, in agreement with which the 

 female (large in the pollen-collecting allies) has degenerated 

 to the size of the male, and has lost its special polleniferous 

 scopa. At the same locality, on the same day, Mr. Grinuell 

 took Andrena prunorum, (Jk.ll., two males. 



Epeolus asperatus, sp. n. 



$ . — Length about 8 mm. 



Black, with the usual ornamentation, pale yellowish cine- 

 reous ; mandibles red except at tips; labrum black, reddish 

 laterally; clypeus black, very densely punctured ; head much 

 broader than long; eyes pale purplish; vertex rugoso- 

 punctate; antennee black, second joint dull reddish toward 

 apex ; mesothorax and scutellum rough with extremely dense 

 punctures ; scutellum bigibbous, the lateral teeth black and 

 very short; lower two-thirds of pleura bare, densely punc- 

 tured; tubercles red, but coveied with hair; tegulae bright 

 apricot-red ; anterior part of mesothorax with two curved 

 bands of pubescence and one joining them, making a letter H. 

 Wings with the apical margin broadly dusky ; nervures and 

 stigma piceous; second t.-c. reduced to a small stump on 

 both sides, so that there are only two subtnarginal cells. 

 Abdomen deep black, with all the bands widely interrupted
