This species was first described by Say under the name of Capsi, f 
ravidus, in bis “Heteropterous Hemiptera of North America pub.) 
lished in 1881,* and afterwards by Herrick-S^haefter! (1848) an 
C. multicolor. In IJbler’s List of Hemipteia \\ est ol the Mississippi* 
jhver (1876), it is catalogued under the genus Calocons , of l ieberi 
but in his notices of the Hennptera Heteroptera m the Harris Col• * 
lection! (1878), it is assigned to Derseocoris (Lirschb.), to which it| 
clearly belongs. 
DESCRIPTION. 
Adult.-CPlate XIV, Fig. 1.) The adult is narrowly oval in out' 
line about one-fourth of an inch (7 mm.,) m length and eleven;, 
hundredths of an inch wide. The general color is dusky, bordered 
with yellow, except the head and thorax, which are oiange brown,J 
The head is triangular in outline, strongly arched above nearly| 
smooth, provided with a few sparse, short hairs which becomej 
longer and thicker in front of the antenme. There is a broac 
shallow depression upon the vertex, and in front of this, upon eithei^ 
side of the middle line, a series of faint oblique grooves running 
backwards and outwards nearly to the eye. Its color is orangtg 
brown, deepening almost to black upon the tylus. The base aicl 
tip of the rostrum are black, the remainder orange brown, like thf 
head. The eyes are red or black. * _ j 
The antennae are very long, reaching the tip of the abdomenJ 
The first joint is longer than the head, much thickened externally 
shining black, and provided with short, appressed hairs. The secon 
joint is nearly three times as long as the first, slender and straightl 
slightly thickened outward, black, with a broad white band on tM 
basal two-thirds. The third joint is about twice as long as the first« 
white on the basal half and red or black distaliy. The fourth join 
is about half as long as the third, with the basal third white anjjj 
the remainder red. 
The thorax is trapezoidal in outline, strongly narrowed for war* 
the anterior margin being two-thirds the posterior. The ^ ^ 
strongly arched and the posterior angles broadly rounded, in 
disc of the pronotum is feebly and sparsely punctured, obscurel j 
rugulose and spaiingly provided with short, yellowish hairs, 
transverse callus immediately behind the head is pale yellow, tin 
remainder of the prothorax a darker yellow, the anterior tourm 
being orange brown, the same color as the head. On the postencj 
third is a transverse black band, rarely attaining the margins o 
-either side, and usually constricted in the middle, often, m lac 
completely divided, when it forms tw r o oblong black blotches 'pl&c® 
transversely. The punctures and hairs of the propleura are H 
those of the disc. Its color is brownish yellow, bordered below wit 
paler. The side pieces of the thorax are brown shading into blacn 
the coxoe, orange brown.
