THE CANADIAN ENTOMOLOGIST. 



post-median, the latter not attaining the sutural angle, I can only say that 

 if the short, broad form of the body and the pecuHar form of the anterior 

 margin of the prothorax are truly drawn, it is entitled to a distinctive 

 name, either as a species or a very peculiar subspecies of parenthesis. 

 The following is also an interesting subspecies o{ parenthesis : 



H. expurgata, n. subsp. — Shorter, rather smaller and relatively 

 broader than parenthesis, highly polished, with distinct moderate 

 punctures, pale brownish-flavate ; prothorax shorter and more transverse, 

 nearly similar in maculation ; elytra with a scutellar dash, rajjidly expanded 

 at its tip and a rounded subhumeral spot, the remainder of the elytra without 

 spots or with a small post-median spot, and sometimes a still smaller 

 subapical one. Length, 4.0 mm.; width, 2.6 mm. Colorado (Boulder Co.). 



Mr. Leng has also figured this form having a small posterior dot. 



This parenthesis group has a distinct suggestion of the two post- 

 scutellar points of the j-signata group, combined with the vitta-forming 

 tendency of the sinuata group and a system of pronotal maculation 

 peculiar to itself.
