Colpoptera maculifrons sp. nov. 
Male. Length, 3.8 mm.; tegmen, 5.4 mm. 
Light brown; slightly darker at base on lateral portion of frons, a 
series of seven or eight lighter spots curving from the outer angles of 
base to near apex in the darker portion of frons; pronotum slightly mot- 
tled with darker marks; mesonotum considerably darker. Tegmina light 
brown, slightly darker in middle, veins same color as membrane except in 
middle, where the Se, R, M, and Cu from one-third from base to near 
nodal line are dark brown or black. Wings brown with darker veins. 
Anal segment long, narrow, anus at base where it is broadest, gradu- 
ally narrowing to acute apex. Genital styles somewhat similar to former 
species, but the apex (corresponding to x in Fig. 4) is produced into a 
spine with its apex bifureate and pick-shape. 
Vertex considerably wider than long, apex very slightly arcuate, base 
slightly, roundly emarginate. In this species there is a very slight sign of 
transverse veins in the costal area. 
Described from one male from Rio Piedras, P. R. (R. T. 
Cotton, 2, 10, 1917). 
Type in U. S. National Museum, Washington. 
The genus Colpoptera Burmeister is difficult to place; it has 
been placed in the Issidae, Ricaniidae, and Flatidae by dif- 
ferent workers. The absence of any sign of granules on the 
clavus should exclude it from the Flatidae, and the male geni- 
talia are not typical of that family. The absence of a distinct 
costal area with distinct cross-veins should also exclude it from 
the Ricaniidae, and the eyes nearly touch the tegulae. If it 
should be placed in the Ricaniidae it would come near to Bladina, 
in which the costal area is obscure. Personally, the writer pre- 
fers to place it in the Issidae until such time as the morphology 
of that family has been more thoroughly worked, and it should 
go into the Thioniini.
