152 DIASPIS : SYNOPSIS OF SPECIES. 



not see (so long as the puparia are tricarinate) that it 

 matters whether they are faintly so or strongly pro- 

 nounced. Mr. Cockerell, however, considered such a 

 character of generic importance, and on these grounds 

 alone established his genus Aulacaspis, including in it 

 all species having very strongly tricarinate male pu- 

 paria. I have retained Dlaspis rosse in Aulacaspis, but 

 for other reasons than that given by the author. See 

 diagnosis of genus.
