OF WASHINGTON. 185 
The genus Verrallina Theobald was founded on female 
specimens only and was referred by its author to the sub- 
family Aedeomyinae, but the present species clearly belongs 
to the Culicinse. 
Tinolestes, new genus. 
Near Aedes, but the lateral scales of the veins of the wings are much 
broader and the palpi in the male much longer. Hairs of antennae of 
male long and abundant, in the female short and sparse. Palpi of male 
nearly twice as long as the head,. almost one-half as long as the proboscis, 
those of the female about as long as the head, less than one-sixth as long 
as the proboscis. Appressed scales of occiput narrow, a patch of broad 
ones each side, numerous upright forked scales on the occiput. Scales 
of scutellum very narrow, metanotum bare. Lateral scales of veins of 
wings broadly oblanceolate, a few nearly linear ones on basal half of 
wings. 
Type: The following species: 
Tinolestes latisquama, new species. 
Scales brown, the appressed scales of the occiput, venter, front angles 
of abdominal segments, coxae, and under side of the femora at their 
bases, yellow. Front and middle tarsal claws of male with one tooth 
under one of the claws, none under the other, claws of the hind tarsi and 
all claws in the female simple. Length 3 mm. 
Port Limon, Costa Rica. Seven males and five females 
collected by Mr. F. Knab. 
Type. No. 8298, U. S. National Museum. 
Micraedes, new genus. 
Near Aedes, but the palpi much longer in both sexes. Palpi noticeably 
longer than the head, about one-third as long as the proboscis, apparently 
two-jointed, the apical joint slightly longer than the basal. Hairs of 
male antennae much longer and more numerous than in the female. 
Clypeus bare. Occiput covered with narrow, curved scales and with 
many upright forked ones, the lateral portions covered with very broad, 
appressed scales. Scutellum bearing very narrow scales and six bristles 
on the median lobe. Scales of legs appressed. Venation normal, hind 
cross-vein over twice its length before the small, the lateral scales of the 
veins very narrow. 
Type: The following species: 
Micraedes bisulcatus, new species. 
Scales of palpi and proboscis black, those of the occiput yellow. Meso- 
notum brown-scaled, a pair of subdorsal bare lines on its anterior three- 
fourths. Abdomen black-scaled, the front angles of the segments whitish-
