ENTOMOLOGICAL NEWS [Dec., 'OQ 



tegulae nearly dark brown. Enclosure of metathorax semicircular, 

 strongly pitted. The first abdominal segment smooth and shining, the 

 compound microscope shows that it is nearly impunctate in the center 

 and sparsely and very finely punctate on the sides. 



Type from Church Bridge, Va., June 9, N. Banks. About 

 the size of P. pygamaea from which the form of the face marks 

 and the spots on the collar easily distinguish it. The face 

 marks resemble those of P. ziziac, from which it differs in 

 its smaller size and the absence of yellow spots on the scapes 

 and tegulae. The shade of yellow of the markings is not stated 

 in the description as they had been reddened in the cyanide jar; 

 but, so far as can be inferred, they were lemon yellow.

Prosopis modesta Say. 



As Say's type is no longer in existence and his description 

 is very brief, the correct identification of this species has been 

 regarded as doubtful. In another paper I hope to show that 

 Say's species can be determined with a high degree of cer- 

 tainty. I have examined the common species of Indiana (the 

 probable type locality) belonging to this genus, and have ob- 

 tained figures and new descriptions of P. affinis Sm. prepared 

 by Col. Bingham from the types in the British Museum, with 

 which P. modesta has frequently been confounded. The name 

 has been so long and so widely used that it is desirable to 

 retain it if possible.
