CaupoUcana vestitn (Smith, 1879), \^\\ piurensis, v. nov. 



Professor C II. T. Townscnd has sent nie four spcc-inieiis, 

 which he collected at Piura, Peru, April 28th, 1911, at 

 flowers of an Ascle[)iadaceous climber, which is perhaps 

 P/iilibertella Jfuva {Philibertia flava, Meyen). Pollen-bodies 

 of the Aselepiad adhere to the legs of some of the specimens. 

 Smith's species was based on a male from Peru. The 

 female is similar, about 15 mm. long. Fresh specimens 

 liavc the hair on checks and underside of body very white, 

 and my material has black legs, with only the tarsi of the 

 males somewhat rufescent. As Smith delinitely states that 

 the tibiae and tarsi are ferruginous in his insect, I regard 

 the Piura form as a variety or race. In the female the 

 middle and hind tibise and tarsi are black-haired on the 

 outer side, but the hind tibise have abundant curled long- 

 white hair beneath. The hind tibine and tarsi are also black- 

 haired on the inner side, and the large scopa of the hind 

 femora is greyish black. Mandibles tridentate in female, 

 bidentate in male ; lobes of tongue very long and pointed ; 

 second s.m. about half size of third ; abdomen of female 

 dorsally with brilliant orange-fulvous tomentum, at sides 

 black (i. e. the surface visible) with broad white apical 

 hair-bands, fifth segment with black hair, white at extreme 

 sides ; male abdomen similar, fifth segment black-haired 

 basally, with a broad white hair-band, and no fulvous except 

 a slender longitudinal median line of hair, which may be 

 absent. 



Ti'igona mellaria, Smith. 



Piura, Peru, at same Asclepiadaceous flowers as CaupoU- 

 cana vestita, var. piurensis, April 28 (C H. T. Toivnsend). 

 At an earlier date males were sent, with the information 

 that the species nests in mesquite trunks. The Peruvian 

 specimens have been compared with a cotype from F. Smith's 

 collection. The male differs from the worker by the much 

 narrower face, with silvery white pubescence at sides, and 

 has more light colour on the legs. The male hind tibiae are 

 largely pale yellow, marked with black and suffused with 

 red. The species was described from Panama.
