54 Psyche [April 



thorax, all yellow; scutellum shining, the punctures larger and much less dense than 

 on mesothorax; legs piceous, the small joints of tarsi light reddish-browTi; a small 

 spot on all the knees, stripe on anterior tibise, and base of middle tibiae above, yellowy 

 hind tibise with silvery-white hair; tegulse light fulvotestaceous; wings dusky; 

 abdomen with bright yellow bands on first six segments, widely interrupted on 

 second and third, with a linear interruption on the others; apical plate very large, 

 obtusely emarginate, bulging laterally; genitalia ferruginous. Third s. m. unusually 

 long. 



Hah. — Independencia, Parahyba, Brazil {Mann & Heath). 

 In the tables by Schrottky and Friese this runs to P. bvrmeisteri 

 Gerst, which however is much larger, and otherwise different. 

 From all the races of P. picia Gerst., it is known not only by the 

 details of the markings, but also by the very much more finely 

 punctured mesothorax. In the shape of the head, and in the 

 face-markings, there is much resemblance to P. philanthoides 

 Gerst., but the head is broader, and the colors are quite different. 

 The name canina may be taken to refer to the bulldog-like head 

 or to the well-developed dog-ear marks. 



Megachile lenticula Vachal.

 coxte, trochanters and basal half of femora are ferruginous above; tegulse clear bright

Hah. — Porto Velho, Rio Madeira, Brazil {Mann & Baker). 

 Madeira-Mamore R. R. Co. Camp 43 {Mann & Baker). Male 

 also at Porto Vehio. I had regarded the female as a new species, 

 but it is evidently the undescribed sex of M. lenticula Vachal. 

 The following table contrasts the female with some species which 

 it resembles.
