THE ORDER OP COLEOPTERA. 
Fab., three-twentieths of an inch long. A much smaller species, the 
C. dispar, Lacord., has been placed in the sub-genus JExema. Babia , 
Chev., is founded upon the B. biguttata, Oliv., and its varieties. It is 
about three twentieths of an inch long, blue-black, with a fulvous spot 
on the shoulder, and another at the tip of each elytra. It differs from 
the great majority of Cryptocephalides in having the tip of the abdo- 
men but slightly, and in many specimens not at all exposed. Saxinis 
omogera , Lacord., resembles the last mentioned insect in size and color, 
except that there is no spot at the end of the elytra. It is found in the 
Southern States and Texas. The genus contains but one other North 
American species. The type of the genus Goscinoptera, Lacord., is the 
G. dominicana, Fab. (Fig. 82), two tenths of an inch long, or a little more, 
black, rather densely covered with a tine ash-colored pubescence. Several 
other species have been found in the remote Western States. The G. 
vittigera, LeC., found in Kansas, is more oblong, and each elytra has a 
fulvous stripe, which is bent uj) like a hook at the end. The generic 
name comes from lcoskinos — a sieve, and ptera — wings, referring to the 
irregularly distributed punctures, somewhat like the holes in a sieve. 
The genus Gryptoceplialus contains many more species than all the 
others combined. It has been divided into a considerable number of 
sub-genera, mostly upon slight or obscure characters. A more conve- 
nient distribution, for the purpose of identification of species, could be 
made in accordance with their colors. The majority are brown, with 
yellow stripes or spots; a considerable number are blue-black, with ru- 
fous or orange spots; and some of the smallest species are wholly blue- 
black or brown.

Sub-family GALERUCIDES. 
Named after the genus Galeruca, 
of Geoffroy. They are distinguished 
primarily from the other Chrysome- 
lidte by the approximation of the 
antennae at their points of insertion, 
iDubko'S being rarely farther apart than the 
V Tha A stiiped length of the first joint, and from

the antennae perfectly filiform, or not enlarged 
towards the tip. The thorax is narrower than 
the elytra, which, together with a similarity 
of coloring, gives to some of the species a 
strong resemblance to the Criocerides, but 
they can always be distinguished by the tho- diabbotica vtitata Larva
