i Glossonotus acuminatum Fabricius. 



This, the type species, does not seem to be common. I 

 have taken it about Buffalo and in southern Ontario and Kan- 

 sas and have occasionally received it from correspondents in the 

 eastern United States. 



In some individuals the dorsal crest is strongly inclined 

 forward in others it is erect and distinctly sinuated both before 

 and behind, but with the limited material at my disposal it has 

 been impossible to separate these as distinct species. Mr. W. 

 T. Davis has sent me a fine large female from Lakehurst, N. J., 

 in which the height to the top of the erect crest is equal to the 

 greatest length of the insect. In all the specimens I have seen 

 the crest is darker than the base of the pronotum and shows a. 

 marginal row of obsolete paler points. 



2. Glossonotus turriculatus Emmons. 



The only specimen I have seen of this species was taken 

 by Mr. W. T. Davis on Staten Island. It is smaller than 

 acuminatus to which it is most closely related, and differs in 

 having the crest more slender and rising vertical from the very 

 front of the pronotum, it is also smaller and the pronotum is 

 without the longitudinal rugae posteriorly. There will be no 

 difficulty in recognizing it from Emmons' figure. 



3. Glossonotus univittatus Harris. 



Found sparingly throughout the eastern United States and 

 Canada. 



4. Glossonotus Godingi VanDuzee. PI. 2. fig. 2. 



Intermediate in character between univittatus and cratcegi. 

 In Ent. News (vi, p. 203, June 1895,) I have given the char- 

 acters separating these three forms. Godingi is our most 

 abundant and widely distributed species, occurring from Quebec 

 to Colorado. 



5. Glossonotus crataegi Fitch. 



Not at all common but widely distributed in the eastern 

 United States. It has the pale marks of the pronotum more 

 strongly contrasted than in Godingi to which it is most closely 

 related. Here the fuscous spot at the apex of the elytra is dark
