CHRYSOMELID-. 
‘Leaf Eaters.” 
The numerous species of this family are mostly small insects, 
many of them of brilliant colors and pretty ornamentation. They 
can be collected in great numbers with a sweeping net, and also 
by using an inverted umbrella. Holding it under the vegetation, 
which is then beaten with a stick. The literature is scattered. 
Crotch, Le Conte and Horn have published many papers (about 
60) in proceedings, Academy Natural Sciences and Trans. Amer- 
Ent. Soc., of Philadelphia, from 1851 to 1880. Since then Dr. 
Horn has published several papers on various genera in Trans. 
“Studies in Chrysomelide,” vol. x1x, p. 1; Eumolpini, 1892, vol. 
XIX, p. 195; Galerucint, 1893, vol. xx, p. 59; Halticim, 1889, vol. 
XVI, p. 163. Mr. Leng revised the Donacia Trans., 1891, XVIII, 
p. 159. As many species of this family play a very important part 
in agriculture ; they have been well studied by the Economic Ento- 
mologists, and their life histories worked out, with figures of many 
of the species and their larvee. This work has been published in 
“Tnsect Life,’ and the reports of the different state Entomologists. 
These reports can be obtained if applied for in time, by those 
interested. Our genera and species are as follows: 
DONACIA. 
D. equalis Say. 3 D. rufa Say 
D. metallica Ahrens. 
Of the 27 N. A. species and varieties of Donacia given by Mr. 
Leng, I have only taken three. This is doubtless due to want of 
suitable environment, such as lakes with lily pads and other 
aquatic vegetation.
