These two specimens, sent by Prof. 

 Bruner, were referred doubtfully by 

 him to Tomonotus zimmermanni 

 Sauss. which is given as a synonym of 

 ChortopJiaga viridifasciata by Saus- 

 sure himself (Prod. Oed., p. 73). 



• By " total " is meant the length of the insect at rest 

 including the tegmina. 



Thev agree with the description of 

 crepitans (I. c.) from Georgia in the 

 greatly compressed form of the body 

 and especially of the head, and the 

 sub-parabolic apex of wings. It seems, 

 however, sufficiently distinct from bolli 

 to be regarded as a different species. 

 The hind tibiae lack the bright ifd 

 coloration of bolli but the specimens 

 may have been in alcohol and had the 

 color largely destroyed.

I have nothing further to add to the 

 synonomy as cited and stated in my 

 previous paper (1. c.) 



The great difference in size between 

 New England and Texas specimens 

 has already been mentioned, linear 

 measurements of the latter being nearly 

 forty per cent, larger. New England 

 specimens are smaller than those of 

 Indiana, Indiana than those of North 

 Carolina, N. Carolina than those of 

 Texas, and, should the specimen de- 

 scribed here as robustiim prove to 

 belong to this species, we have reason 

 to think that Mexican specimens are 

 even larger than those of Texas. This 

 is not improbable, specimens of cris- 

 tatiim from the Gulf coast of Texas 

 being decidedly larger than those from 

 Dallas in that State. Individuals also
