THE STUDY OF INSECTS. 
(Thec-e-ster'nus hu-mer-a'lis), of the central portion of the 
United States. It usually lives near the surface of the 
ground, but has been found attacking grape-vines and hick¬ 
ory. It is a grayish beetle, one third to one half inch in 
length, and with its wing-covers roughened by rows of tu¬ 
bercles. Its distinctive structural characters are given in 
the table of families. 
Family OTlORHYNCHlD,£ (O-ti-o-rhyn'chi-dae). 
The Scarred Snout-beetles. 
This is one of the larger of the families of snout-beetles, 
including more than one hundred North American species. 
The most distinctive characteristic of these insects is the 
presence in the pupa state, and sometimes also in recently 
matured adults, of an appendage on each mandible, and in 
the adult state of a scar indicating the place from which the 
appendage has fallen. This scar is on the anterior face of 
the mandible, and frequently at the tip of a slight process. 
Many species of this family are beautifully ornamented with 
scales which resemble in a striking manner the scales on 
the wings of butterflies. Among the more important species 
are the following : 
Fuller’s Rose-beetle, Aramigus fulleri (A-ram'i-gus ful'le- 
ri).—This is an oval, black snout-beetle, lightly covered with 
dark-brown scales, and about one fourth inch in 
X length. It is very destructive to roses; the 
WiV larvae feed upon the roots, and the adults de- 
stroy the leaves, flowers, and buds. In Cali- 
£° rn i a it is sometimes a pest in orange-groves. 
r The Imbricated Snout-beetle, Epiccerus inu 
bricatus (Ep-i-cae'rus im-bri-ca'tus) is usually a 
Fig. 723. dull, silvery-white beetle with brown markings ; 
but the species is quite variable in color. It is represented 
somewhat enlarged by Figure 723. It is omnivorous, gnaw¬ 
ing holes in various garden vegetables and fruits, and in the 
bark of trees and shrubs.
