172 THE CANADIAN ENTOMOLOGIST. 



Described from a single female example taken at Mt. Balsam, N. C, 

 Aug. ist, 1890, by my friend Mr. W. J. Palmer, jr., of this city, to whom 

 I take pleasure in dedicating this singularly neat and elegant little species. 

 This is certainly a notable addition to the homopterous fauna of this 

 country. It is a remarkably trim compactly built little creature, mimick- 

 ing very closely the genus Fediopsis, from which it differs, however, by all 

 the characters separating that genus from the Jassidee proper. In its 

 intensely black colour it has few equals in our Jassid fauna. In mounting 

 this specimen the apex of its clypeus was unfortunately covered so its 

 characters cannot be given. 



DESCRIPTIONS OF SOME BUTTERFLY LARV^ FROM 



YOSEMITE.— I. 



BY HARRISON G. DYAR, YOSEMITE, CAL. 



Limeiiitis lorqiiifiii, Boisd. 



Egg. — Nearly spherical, the base flat ; covered with elevated reticula- 

 tions from the intersections of which arise short spines. The depressions 

 between the reticulations are rounded. Colour pale green with a silvery 

 lustre. Diameter .9 mm. Laid singly at the extreme tip of a leaf on the 

 upper surface. 



First larval stage. — Head rounded, brown, not shiny ; ocelli and 

 jaws black ; a few minute hairs arising from yellowish elevated bases ; 

 width .6 mm. Body slightly enlarged at joint 12 ; feet normal. Colour 

 yellowish, with rows of short conical tubercles, which are largest dorsally 

 on joints 3, 4, 6 and 12 ; some very short and minute hairs. The larva 

 builds out a long perch in continuation of the mid-rib of the leaf on 

 which it rests. It collects a little bundle of bits of leaf, etc., at the base 

 of this perch. 



Second stage. — Head rounded, brown, with two paler lines in front 

 converging toward the vertex. It is roughly tuberculate, the tubercles 

 yellowish. Width .9 mm. Body densely tuberculate, each tubercle with 

 several points, beside many minute granulations. General colour dark 

 brown, with a broad, dull ochre, dorsal patch, which widens on joints 3- 

 5 and 8-10. The larva rests on its perch as in the first stage. 



Third stage. — Head bilobed, bulging in front, very rough and tuber- 

 culated, but the tubercles are not large. Colour nearly black, the 

 clypeus and tubercles paler, the latter tipped with yellowish on the sides
