which are separately rounded, surface brown, sparsely, rather finely punc- 

 tured, sparsely clothed with long prostrated reddish-brown hairs inter- 

 mixed with long erect ones of the same color, and with a very narrow 

 sutural stripe of dense prostrated whitish hairs. Scutellum subquadrate, 

 rounded behind, surface densely punctured and densely clothed with long 

 prostrated hairs. Underside fusco-piceus, surface densely punctured, 

 clothed with long prostrated whitish hairs. Femora, tibia; and tarsi brown, 

 sparsely clothed with semi-erect hairs. Fifth ventral segment about as 

 long as the fourth, broadly emarginate behind. Length 10 mm.; width 

 3 mm. 



Female: Differs from the male in having the fifth ventral segment 

 longer than the fourth and rounded behind. Length 12 mm. ; width 3 mm. 



Habitat: Monumental Mines, California. Elevation 3600 feet. 

 P. D. Sergent, collector. 



Type and allotype: Cat. No. 19130 U. S. N. M. 



Described from five specimens, four males and one female, 

 recorded under Bureau of Entomology Number Hopk. U. S. 

 10856d. Reared by Mr. J. M. Miller from old cones of Pinus 

 attentuata, collected October 2, 1913, by P. D. Sergent. 



This interesting species is somewhat suggestive of a narrow 

 Atimia confusa. It differs from that species by its reddish-brown 

 color, elytra with a narrow whitish sutural stripe and tips sepa- 

 rately rounded, thorax not wider than long and being somewhat 

 cordiform. 



DESCRIPTIONS OF NEW NORTH AMERICAN 

 MICROLEPIDOPTERA. 



BY AUGUST BUSCK. 



In one of my early papers (Journ. N. Y. Ent. Soc., vol. VIII, 

 1900, p. 234), I expressed^the opinion, that in the then existing 

 unsatisfactory state of our knowledge of American Microlepi- 

 doptera, it was of little value (or worse) to describe promiscu- 

 ously new species from collected material; only when working 

 up a group systematically did it seem to me excusable to describe 

 species of which the biology was not known. 



This attitude has influenced my production of descriptive work 

 during the past years and I have described new species only as 

 the demand for names from correspondents necessitated it, or 

 when other considerations made it desirable or obligatory. There 

 are for this reason hundreds of Micros as yet undcscribed in the 

 collection of the United States National Museum. 



I still have a disinclination for new species of which we know 

 nothing more than the type specimens, (and the present paper
