mose. Abdomen shorter than the hind wings, broad at the 

 base and becoming abruptly pointed. Fore wings much pro- 

 duced at the apex, wider than the hind pair, which are rounded 

 on the anal angle, and produ/:ed at the apex. Tibiee unarmed, 

 but clothed with rather long spreading hairs.

Wholly brassy black, the scales of the primaries with some- 

 what metallic points.

 Francisco Mts., Arizona: 



A singular little insect, difficult to refer to any known fam- 

 ily. I believe, however, that I am right in placing it in the 

 Psychidcn, but this cannot be established until the 2 is known, 

 and some observations have been made upon its life-history. 



Clisiocampa incurva. n. sp. 



It is rather a hazardous experiment to describe a species of 

 this genus, without a knowledge of the preparatory stages, but 

 in the present form I find some characters, which, after a careful 

 comparison with the types of the described Pacific Coast species, 

 (all of which are contained in my collection,) entitle it, I believe, 

 to a specific rank. It is most nearly allied to C. erosa, Stretch, and 

 C. fragilis. Stretch, but differs abundantly from both. The 

 ground color of the $ is pale fawn color, of the ? , a darker 

 shade, inclining to a brownish tint. The basal space in both 

 sexes is paler than the rest of the wing. The strongest character 

 is afforded by the anterior line, which is curved, and starting from 

 costa about 4 m. m. along its edge from the base, turns below 

 in the middle, and passes quite into the base of the wing on 

 the internal margin. In all the other N. Amer. sp. there is a 

 space on the internal margin between the junction of this line 

 and the base of the wing, and I believe it is in the position and 

 shape of the two lines of the primaries that the best characters 

 for separating the species in the imago state may be found. The 

 outer band in the present form is more regular, bent a little out- 

 wardly in the middle, and in the ? slightly dentate, the anterior 

 band being without teeth in both sexes. In this respect it ap- 

 proaches C. fragilis, but in the Nevada species there is a space 

 between the junction of the anterior line, and the bas.e of the 

 wing, while the $, is totally different. (See " Papilio " Vol. I., 

 p. 64). I have no doubt of the validity of C. incurva as a species, 

 but, where it is possible, the most careful attention should be 

 given to the species of this genus in their earlier stages.
