 This species is a close relative of texaifieUa Mickel. The female is 

 easily distinguished from the latter by the color and pattern of the 

 pubescence. It may be recognized at once by the absence of a scu- 

 tellar scale and the presence of a median spot of silvery pubescence 

 at the apex of the second abdominal tergite. I have examined the 

 types of blmva, hruneri, and segregata var. finni^ and find them to be 

 identical with this species. The male of sparsa is hirticula Mickel. 

 The male and female listed above from Blue Hills, Mass., were taken 

 in copula. The female is a specimen of the following variety seg- 

 regata^ while the male is a typical specimen of hirticula. The geo- 

 graphical distribution of sparsa and its variety segregata extends 

 from the Atlantic coast west to North Dakota, Colorado, Oklahoma, 

 and Texas, while hirticula occurs throughout the same area, Hirticula 

 is the only male Dasymutilla whose geographical distribution coin- 

 cides with that of sparsa and its variety segregata. There are no 

 differences in the male specimens from the eastern states and those 

 from the western states by which they can be separated. Most of 

 the female specimens from the eastern and southern states belong 

 to the variety segregata^ but the female specimens listed here from 

 Georgia and Florida are typical sparsa with a median spot of silvery 

 pubescence on the apical margin of the second abdominal tergite. 

 Segregata var. finni described by Kohwer from Georgia was based 

 on such a specimen.
