ing with flashy speed after a prospective victim. They are a fear- 
less tribe ; L. pulchella especially is very reckless, not in the least 
afraid of human beings and fairly tempting the collector by its 
audacity.

*) To make clear the specific validity of L. flavida Hagen, flavida 
Eambur, plumhea Uhler, cyanca Fabricius and quadrupla Say, Prof. 
Calvert undertook the trouble of examining the types of the different 
species and of otherwise studying them thoroughly. (Ent. News, Vol. 
18, p. 201-204, 1907). The results, it may be said, are final. After thor- 
ough investigation Prof. Calvert concluded that, first, flavida Hagen 
was a valid species, and, secondly, flavida Eambur was identical with 
plumhea Uhler, and also cyanea Fabr. with quadrupla Say. Thus we 
have three species: flavida Hagen, flavida Eambur fplumbea Uhler), 
and cyanea Fabr. (quadrupla Say.) The second species, hitherto 
called plumljea Uhler had to receive the name of flavida Eamb. be- 
cause of the priority of the latter and Prof. Calvert proposed the name 
comanche for flavida Hagen. Thus the final result is : 
comanche Calvert = flavida Hagen. 
flavida Eambur = plumhea Uhler. 
cyanea Fabr. = quadrupla Saj-.
