This is an immigrant species which is nearly cosmopolitan in dis- 

 tribution. Wherever it is found, it is generally common in grassy 

 areas.

My thanks are due Mr, P, Viette, Museum National d'Histoire 

 Naturelle, Paris, who has examined Gay's type in that Institution, 

 and compared the genitalia with my drawing. He writes as follows: 



"I have examined the cf type specimen of Elasmopalpus angustellus 

 Blanchard, from Chile. Your drawings correspond exactly with the 

 genitalia of the type specimen in Paris Museum. — Slide P. Viette 

 N:3544." 



Although angustellus has been considered a synonym of lignosellus 

 by various authors, there are abundant points of distinction. In the 

 male genitalia there is a strong projection from the costa, slightly 

 before cucuUus, which is absent in lignosellus. The lateral arms of the 

 anellus of angustellus are slender and only slightly curved, not strongly 

 sclerotized, curved, pointed horns as in lignosellus. The single cornu- 

 tus is thick, strongly sclerotized and nearly half the length of the 

 aedeagus in angustellus but appreciably shorter and more slender in 

 lignosellus. The ductus bursae of the female is broad and strongly 

 sclerotized for over three-quarters of its length in angustellus and the 

 spines of the two opposing sclerotized signa are stouter than in 

 lignosellus. 



For the above reasons I am removing angustellue from the synonymy 

 of lignosellus. The specific name E. angustellus must be confined to 

 the Chilean examples since all other specimens examined from
