This and other species of the genus may be separated from Mr. 
Baly’s genus Jphitrea (Ent. Monthly Mag. 1864, 134), of which I 
am not so fortunate as to possess a typical specimen, by the obvious 
difference in length between the third and fourth joints of the an- 
tenne; in this species and others the third is very distinctly 
shorter than the fourth.
