y. Males of this genus, according to Kieffer, have the nodes of the 
flagellate antennal segments very unequal. The small, yellowish 
species belonging here may be recognized by the anterior uniden- 
tate claws, the quadriarticulate palpi, the lack of a conspicuous 
lobe or spine on the basal clasp segment, and by the linear, emar- 
ginate ventral plate. The dorsal plate is deeply incised, the lobes 
oblique or slanting and broadly rounded. Type C. cilicrus Kieft

This insect was reared in July 1893 from the basal portion of the 
stems of Iceland poppies, Papavaer nudicaule, trans- 
mitted to the Federal Department of Agriculture by Mrs Celia 
Thaxter, Portsmouth, N. H. The larvae were rather abundant in 
the plant tissues. 
Male. Length 1 mm. Antennae twice the length of the body, 
thickly haired, probably pale yellowish; 14 segments, the fifth with 
stems two and three times their diameters; terminal segment, basal 
portion of the stem with a length four times its diameter, the distal 
part strongly constricted near the basal and distal thirds, apically 
a short, stout appendage. Palpi probably quadriarticulate. Meso- 
notum brown, the submedian lines yellowish. Scutellum yellowish 
apically. Abdomen yellow. Wings hyaline, costa yellowish. Claws 
long, slender, evenly curved, the anterior minutely unidentate, 
pulvilli shorter than the claws. Genitalia; basal clasp segment 
short, stout; terminal clasp segment long, stout, slightly expanded 
distally; dorsal plate long, deeply and narrowly incised, the lobes 
obliquely truncate; ventral plate long, broad, broadly and roundly 
emarginate, the lobes slender, narrowly rounded. 
Female. Length 1.5mm. Antennae as long as the body, sparsely 
haired, light brown; 14 segments, the fifth having the stem about 
one-third the length of the cylindric basal enlargement, which latter
