Anal segment longer than broad, in outline basal half slightly coneave, 
apical half slightly convex, apex slightly arcuately emarginate; anus in 
apieal half. Posterior genital styles laterally flattened, triangular, exca- 
vate in middle, apex with a number of spines curved inward; median and 
anterior styles covered by posterior styles. 
One female specimen from Lares, Porto Rico (G. N. Wol- 
cott, June 14, 1921, Acc. No. 130, 1921). 
Type in U. S. National Museum, Washington. 
ISSIDAE. 
Colpoptera brunneus sp. nov. Plate XII, Figs. 4, a, b, c, d. 
Male. Length, 3.7 mm.; tegmen, 4.6 mm. 
Dark brown, lighter over genae, lighter spots in middle of frons, over 
carinae of head and thorax, legs lighter. Tegmina dark brown, light brown 
over costal area and cell, and a few small, light marks in clavus; veins 
same color as membrane except apical veins which are light, a light mark 
at stigma and at apex of clavus. Wings fuscous, slightly lighter at base, 
veins dark. The tegmina are generally covered with a light powdery 
secretion. 
In lateral view lateral margins of pygofer straight or slightly concave, 
anal angle rounded, not produced. Anal segment fairly large, anus in 
middle, apex rounded. Genital styles large, subtriangular, two ridges run- 
ning across apical half, outer margin irregularly sinuate. Periandrium 
forming a tube, deeply and narrowly emarginate, or cleft, on ventro-apical 
margin, with a long, thin process arising from the bottom of the emargi- 
nation (Figs. 4, a), and from each side of the emargination arises a bifur- 
cate, spine-like process; the penis is large, membraneous or but slightly 
chitinized, with a pair of curved spines about middle of ventral aspect. 
Female. Similar in size and color to the male. The tegmina of this 
species has the costal vein leaving the costal margin one-fourth from the 
base and forming a narrow costal area without cross-veins; the Se and R 
simple, and forming a short stalk; M bifureate about middle, M38+4 join- 
ing R for a short distance; Cu forking near apex. In the hind wings 
there is an emargination at the apex of Cu, as well as one in middle of 
anal area; no granules on the clavus. Vertex much wider than long, trun- 
cate at apex, slightly concave at base. Basal margin of pronotum widely 
angularly emarginate, lateral carinae following hind margin of eyes. 
Described from three males and two females from Utuado, 
P. R. (G. N. Wolcott, November, 1921, Acc. No. 475), one male 
and two females (type locality), one male from Toa Alta (G. N. 
Wolcott, April 21, 1921, Acc. No. 105, 1921), and one male
