long as the next two, last ventral not much shorter than the 

 two preceding united. LeConte's original description calls 

 for four specimens, but the collection now contains only the 

 unique type here briefly characterized. 



A{{inis.—Ty\ie 9 , 1.95 mm. long, hind tibiae straight, 

 second funicular joint a little longer than wide and a little 

 longer than the third, but evidently shorter than the next 

 two ; last ventral distinctly shorter than the two preceding. 



Second example — a cf — 2 mm. long, agreeing with ca/ms 

 except that the second funicular joint is shorter, about one- 

 half longer than wide, and relatively longer than in the first 

 example though shorter than in canus. 



Third example — 9, 2.1 mm. long, second funicular joint 

 twice as long as wide and four-fifths as long as the two fol- 

 lowing. 



A^«««^— Type, 9 , 1.6 mm. long, virtually identical in an- 

 tennal formation with type of affinis. 



The types of canus and affinis have the scaly covering 

 pretty well preserved and seem to be uniformly white ; all 

 other examples are much abraded, but the scales are large 

 and white in all specimens. 



The namis of the Dietz Revision and of most collections 

 is not the true nanus of LeConte, but either the A. tenuis or 

 the Epimechus gracilis of the present paper. 



Neoniastix punctiilatus Dietz. 



Dietz expresses a doubt of the distinctness of this from 

 solidaginis. I believe his suspicions are well grounded and 

 should call them identical. 



EPIMECHUS Dietz. 

 E. gracilis n. sp. — Form very narrow and elongate, black, antennae 

 — except the club, — legs and sometimes the beak rufous or rufotestace- 

 ous ; vestiture dense, white throughout, consisting of large broadly oval 

 or rounded more or less overlapping scales. Beak ( cf ) but slightly longer 

 than theprothorax, shining, squamose at base, finely not densely punc- 

 tate,, substriate laterally. Antennae inserted at the middle of the beak 

 in the cf, funicle 6-jointed, second joint a little longer than the third 

 but evidently shorter than the next two together. Prothorax evidently 

 wider than long, widest at or a little behind the middle with the sides 

 moderately arcuate, or with the sides subparallel and very feebly arcu-
