ible in dorsal view than in the other species. The penis pro¬ 
jects downward from beneath the cover, and a very slender 
intermediate appendage (or penis sheath) with a long spine near 
the tip lies on the other side. The distal portion of the inferior 
appendages curves backward rather abruptly, a stout, brown, 
spine-like branch lying in the curve of the posterior edge; ven- 
trally each appendage is prolonged into a straight posteriorly 
directed portion ending in a short spine. Tips of inferior ap¬ 
pendages fulvous; superior appendages gray. 
The other stages of this species are wholly unknown to me.

Imago .—Length of body, 8-10 mm. Expanse, male, 27-28 
mm.; female, 23-26 mm. Antennae, male, 32 mm.; female,. 
16-18 mm. Basal portion of antennae white with narrow brown 
or fuscous annulations, becoming wholly brown on the distal 
portion. Basal joint bulbous, a concavity on the head just pos¬ 
terior to it, into which it fits when folded back. Palpi yellow. 
Head and thorax fuscous, or, in fresh specimens shortly after 
transformation, green to yellow. The warts on head, pro- and 
mesothorax, and the wing callosities, all clothed with long snow- 
white hair; snow-white pile in the interspaces which, with a high- 
power, is seen to consist of a clothing of scales. A Y-shaped 
wart on the head lies with the stem between the antennae, the 
forks extending backward and outward; a large oblong trans¬ 
verse pair posterior to the branches of the first; a smaller pair 
at the outer posterior side of the larger pair, just behind the
