The present species is very similar to Orthe- 
sia insignis Doug., but can be readily distinguished 
from that species by the ovisac, wich is very much 
longer in this new species. 
The eggs are light brown in color when fresh- 
ly laid, becoming darker later on. They are oval 
in form, and are 0.372 mm. long and 0.201 mm. 
wide.

The adult female is brick red in color, with 
the entire surface of the body covered with a thin 
layer of white dust. The body is oval in form, with 
the abdominal segments well marked, and is 5.500 
mm. long and 4 mm. wide. 
Boiled in a solution of KOH, the derm be- 
comes soft and transparent. The antennae are 0.310 
mm. long and are composed of 7 joints, that have 
the following lengths: (1), 45; (2), 52; (3), 92; 
(4), 32: (5), J2s (6), 395 (7, TS. The approx

of the claw are wanting. There are four small el- 
liptical orgãos, one pair of which is located near 
the anterior extremity of the body, and the other 
pair near the posterior extremity. The anal ring 
has 6 hairs. The entire surface of the derm is pro-
