Pneumaculexr DyarR, Proc. Ent. Soc. Wash., vol. T, p. 46, 1905. 
A small genus of wide distribution, all the species addicted to 
water in tree holes and similar locations, and on account of this re- 
stricted breeding habit, all the species are rare. Many of the adults 
are handsomely ornamented. Only a single species occurs in the 
United States. 
ORTHOPODOMYIA SIGNIFER Coquillett. 
Culex signifer CoquitLett, Can. Ent., vol. 28, p. 43, 1896. 
A medium-sized to small blackish mosquito. Mesonotum dark 
brown, marked with bluish silvery lines as follows: A line on each 
side about the margin; two central lines, running three-quarters back ; 
two short posterior lines a little outside these; two short divergent 
lines on antiscutellar space. Abdomen black, with diffused pale basal 
segmental bands, widening on the sides; ventral segments narrowly 
pale at their bases, black outwardly. Legs biack with pale scales, the 
femora pale beneath; tarsi with white rings involving both ends of 
the joints, rather broad on the hind legs. Wing scales black and whit- 
ish mixed, forming a white patch at the end of the cell. 
The larvae live in tree holes. The eggs are placed on the sides of 
the cavity and are covered with a membrane. The adults rest on the 
trunks of trees, and could formerly be caught in the parks of Wash- 
ington; but of late years the attention given to the trees has destroyed 
most of the breeding places. This species is close to Orthopodomyia 
pulchripalpis Rondani (=albionensis MacGregor) of Europe; but 
that has the two lines on antescutellar space joined in front to the 
median lines, forming a closed loop.
