and both pairs of wings are crossed by a narrow blackish 
band. This species is quite widely distributed ; but is quite 
rare in most places. 
The other representative of this family found in the 
United States is Lacosoma chiridota (Lac-o-so'ma chir-i-do- 
ta). This species is even more rare than the preceding; it is 
somewhat smaller, and dark yellowish brown in color; but 
its general appearance is very similar. The venation of the 
wings is also similar to that of Cicinnus except that vein 
VIII of the hind wing is wanting. 
Family LASIOCAMPID^E (Las-i-o-cam'pi-dae). 
The Lasiocampids {Las-i-o-cam'pids ). 
This family includes the Tent caterpillars and the Lap¬ 
pet-caterpillars. The adults are stout-bodied, hairy moths of 
medium size. The antennae 
are pectinated in both sexes, 
and are from one fourth to 
one half as long as the front 
wings; the teeth of the an¬ 
tennae of the male are usu¬ 
ally much longer than those 
of the female. The ocelli are 
wanting ; and the palpi are 
usually short and woolly. 
But the most distinctive char¬ 
acteristic is found in the 
wings. The frenulum is want¬ 
ing, there being instead, as 
in the Saturniina, a largely- 
expanded humeral angle of 
the hind wings. But these 
moths differ from the Satur¬ 
niina in having CUbitUS ap- F,c - 44*-—Wings of Clisiocatufa americana.
