The Moth. 

 Dr. Fitch has given an excellent detailed description of the moth, 

 which, in consideration of the small edition of the Report published 

 and its scarcity at the present time, we herewith present : — 



"The MALES [represented in Fig. 22] measure 0.60 inch in length 

 to the tip of the abdomen and of the wings, and one inch across the 

 latter when they arc spread. The head is densely clothed with white 

 hairs in frout and with blackish ones upon each 

 side around the eyes. The feelers are minute and 

 are wholly enveloped and concealed by fine long 

 hairs, tlieir ends forming a slight projection, like 

 the point of a camel's hair pencil. 'J'hese hairs 

 are blackish on their outer sides and ash-gray 

 within. The antenna3 are short, about a third of

diivciions from their crook near their middle, when they present the 

 shape of an inverted V. Tiiey are furnished Avith two rows of coarse 

 branches, which are long from the base to the crook, where they are 

 abruptly shortened to lialf their previous length, and continue thence 

 to gradually diminish in length to their tips. Each branch has a row 

 of very fine hairs along one side resembling eye-lashes. The mouth 

 has only the minute rudiments of a spiral tongue, and this not coiled 

 as we see it in moths generally. The thorax is clothed with long 

 hairs of a dark gray color, those at its anterior end white, and on I'ts 

 posterior part is an oblong crest of glossy scales, slender and hair-like, 

 with their ends dilated into an oval, flattened knob, in shape resem- 

 bling a spoon, of an auburn-brown color, arranged like the hairs ol a 

 moustache, and jutting up from the surrounding prostrate hairs, form- 

 ing a hirge tuft or protuberant oblong spot, broadest ])ost(Tiorly and nar- 

 rowing to its anterior end. The abdomen tapers slightly from its base 

 to the tip, and is clothed with blackish hairs above, whitish ones be- 

 neath, its apex having a dense tuft of long, pure white ones. The wings 

 are quite small for such a thick-bodied, heavy moth. They are semi- 

 transparent, being thinly covered with brown scales which are commonly 

 denuded, the wings then appearing perfectly transparent, like glass. 

 Their veins are robust and white, with darker, irregular bands. Tlie 

 hind margins of both pairs of wings are entire and not in the least
