By Frep. C. Bowprrcu. 
Colaspsis, Fabr. \ 
Some of the unplaced forms on p. 34 of M. ‘Sey CORBY, S i 
figure out as follows: Ainea, Fab., probably a form ~% 
Boh.; castanea, Boh., occurs at Cachabe, Keuador ; ferruginea, 
Fab. = Colaspoides vulgata, Lef.?; fulva, Fab. = EHriphylina ?, 
sp.; fuscitarsis, Boh., geminata, Boh., and rustica, Boh., all are 
valid species from Rio; humeralis, Lec., and puncticolls, Say., 
belong to Nodonota; lateralis, Germ., might be Sibotes ater, 
Lef. ?; rugosa, Germ., is a well-defined form with a somewhat 
curved metallic-green stripe from the shoulder nearly to the 
apex; unicolor, Oliv., a Cuban form nearly allied to trivialis, 
Boh., oregonensis, Cr., and chrysis, Oliv., would seem to be more 
naturally placed in V'alurus, Lef., than in Colaspis. 
Colaspis humeralis, Baly. = Agbalus. 
Colaspis geminata, Lef., nom. proc. = Lefevrei, Bow. 
Alethaxius verrucosus, Jac: = Colaspis nigrimana, Lef. 
Colaspis aureopunctata, Lef. = Campylochira 2. 
Campylochira fulvicornis, Jac. = aureopunctata, Lef. 
Mr. Lefevre, in his description of Colaspis interstitialis, ‘Ann. 
Fr.,’ 1876, p. 141, speaks of the dilation of the hind tibia of the 
g. The males of the following species show something similar : 
Colaspis eruginosa, Germ.—Inner edges dilated at middle 
third, the rear declination rather abrupt. 
C. viridissima, Lef.—Inner edge biuntly dilated a little 
behind the middle, the front and rear declination even. 
C. townsendi, Bow.—Inner edge feebly dilated at about 
the middle. 
C. lebasoides, Bow.—Inner edge gradually dilated to 
posterior third, then of even width to end. 
C. interrupta, Har.—Gradually dilated from middle to 
end. 
C. haroldi, Jac.—The type is ¢ ; what I consider the g 
has hind femora with a bifid tooth, tibia rather strongly 
sinuate both ways at either end of the middle third. 
C. interstitialis, Lef.—Inner edge feebly dilated and 
sinuate at beginning of posterior third.
