rin with it a mixture sarteadked of one part of Paria green to twenty 
of flour. The reason why we recommend flour instead of plaster, 
other substances, as a diluent, is that flour is attractive as food for 
oe he beetles, and they will eat the poisonous mixture more readily.” 
d Description —tThe beetle is from 4 mm. to 6 mm. in length, ob- 
long and very convex. Color deep shining black, beneath brownish, 
legs dark reddish brown. The head has three frontal tubere ‘les, very dis- 
tinct in the male, less so in the female. Clypeus projecting over and 
concealing mouth parts, front margin broadly emarginate at middle, 
without angulation. Antenne nine- ~jointed, with a three-jointed club. 
Thorax convex, rather finely and sparsely punctured. Wing covers with 
closely punctured striw, intervals feebly convex and with few minute 
if ~ punctures, the first interval broad, a little wider than those adjoining, 
instead of being distinctly narrower, as in other species of similar ap- 
pearance. Tibiee two-spurred, abdomen with six free ventral segments.

‘This beetle is included among insects injurious to seed corn upon 
the evidence of a single observation made by Mr. F. M. Webster in In- 
_ diana. It is not uncommon in Illinois, and is found from New York 
and the north Atlantic States to Kansas and Kentucky. 
Je Nothing is known of its earlier stages. Most of our specimens are 
from electric-light and miscellaneous sweep-net collections, ranging 
_ from May 6 to November 15. 
' The only recorded case of injury to vegetation by this beetle is re- 
ported by Mr. Webster in “Insect Life,” Vol. IIL., p. 159. Under date 
of June 11, 1890, he says, “I received from Whitley county, Indiana, a 
a considerable number of these beetles, with the statement that they were 
found in a piece of ground which had been broken the preceding spring. 
__ the field being swampy and of a black soil, like those infested by wire- 
E> worms. The beetles attacked the seed grains as soon as the latter be- 
S came moistened. When received, one of the beetles had burrowed into a 
kernel of corn in the vicinity of the germ, and was engaged in devouring 
. _the substance.” 
3 In all probability this species, like others of the family, is essen- 
tially carnivorous in its ordinary habits. - 
Description. —This beetle is 6 to 7 mm. long, and about one fourth 
as wide. It is rather depressed and elongate, shining dark red in color, 
S tinged partly with blackish. The prothorax is not applied closely to the 
% hinder part of the body, being connected with it by a short peduncle. 
g The fore legs are very thick and strong, and the fore tibie strongly 
toothed. In the row of spines on the outer edge of the middle tibia, is 
ae of double thickness near the tip of the tibia. The prothorax and 
wing covers are parallel-sided, the former squarish, the latter sud- 
_ denly rounded off at tip, and with punctured strie.
