This is the most common and widespread member of the genus in 

 the United States. Great variation is exhibited in the general size 

 and color of individuals and also in the reticulations of the elytra. 

 The fact that the species has at various times been described imder 

 several different names is due to these mentioned variances. Bio- 

 logic observations will prove the writer's opinion that the several 

 so-called forms have no basis for specific value, and that the above 

 names are correctly placed in synonomy. Sp&ngberg laid too much 

 stress upon the character of the reticulations of the elytra in sepa- 

 rating and grouping species. While the majority of specimens of 

 octo-lineata Say examined have reticulations on the clavus as well as 

 corium, every gradation to the other extreme of no reticulations on 

 any portion of the elytra have been seen. Again some specimens are 

 brilliantly colored with red, while others are solidly green, and even 

 some nearly white. However, the form and shape of the female 

 genitalia is identical in each so-called form. 



The species has been recorded from every section of the United 

 States and from southern Canada. 



3. GYPONA PRUINOSA Spingberg. 



Gypona pruinosa SpAngberg, K. Svenska Vet. Akad. Handl., vol. 5, No. 3, p. 9, 



1878. 



This species resembles octo-lineata Say in general appearance. The 

 female segment rather than being simply and deeply sinuate is dis- 

 tinctly and shallowly trisinuate. As far as available records show 

 it is restricted to ''east of the Kocky Moimtains." 



4. GYPONA GEMINATA Osborn. 



Gypona geminata Osborn, 20th Rept. State Ent., New York, p. 513, 1905. 



The shorter vertex and nearly truncate female segment will serve 

 to separate this species from octo-lineata Say, its nearest relative. It 

 is somewhat smaller and lacks the amount of reticulations that is 

 common to the majority of specimens of octo-lineata Say. The re-
