26 THE ENTOMOLOGIST. 
C. trivialis, Boh.—Inner edge strongly dilated and outer 
sinuate at the middle third, the rear decline being most 
abrupt. 
C. goyazensis, Bow.—Both edges very feebly sinuate at 
the posterior third, nearly the same width throughout. 
C. geminata, Boh.—Inner edges very gradually dilated 
to posterior third, then slightly simuate and straight to end, 
the outer edge nearly straight. 
C. inconspicua, Jac.—Inner edge evenly brought to a 
point in the middle and sinuate at rear end. 
C. dilatipes, Bow.—Inner edge strongly dilated, occupy- 
ing the posterior part of the middle and anterior part of the 
rear third, the dilated edge evenly curved from front to 
rear. 
C. klagii, Bow.—Inner edge sharply and evenly dilated 
to a point just back of the middle. 
C. perplexa, Jac.—Inner edge feebly dilated at middle 
and then straight to tip. 
C. punctipennis, Bow.—Inner edge evenly dilated to a 
point behind the middle, the outer edge rather strongly 
sinuate. 
C. gemmingert, Har.—Inner edge strongly and evenly 
dilated at middle, outer edge sinuate back of it. 
C. confusus, Bow.—Nec gemmingeri, Har. Jac., ‘ Biolog.,’ 
vol. vi, pt. 1, p. 137; inner edge strongly dilated at posterior 
third. 
Colaspis cribricollis, Lef. 
Is described as having wholly fulvous antenne. In ‘ Psyche,’ 
vol. xx, p. 125, was published a note on the phytophaga of the 
Stanford expedition to Brazil; specimens from Independencia 
were referred to this species with a query. The antenne cf the 
Stanford examples have the seventh and last two articles nearly 
black and the hind tibia of the 3 feebly dilated at the posterior 
third. There is at hand only one example of cribricollis 8, so 
I am unable at present to definitely establish the Stanford form, 
but it is very probably distinct. 
Jacoby, in ‘ Biologie,’ vol. vi, p. 187, under Colaspis gem- 
mingert, Har., refers to that Brazilian species the Mexican 
forms, merely stating the former are larger and more narrowed 
behind ; both forms have the hind ¢ tibia dilated within. Von 
Harold, speaking of his species (the Brazilian), says the tibia 
dilated at the middle, the Mexican 3’s have the dilation nearer 
the apex, therefore I differentiate the latter under the name of 
confusus, Bow. In this connection it may be noted that I have 
seen no examples of either form from the territory between 
Honduras and Brazil; I have ten examples from Mexico and 
fifteen from Brazil.
