H. C. FALL. 53 



convergent from the base, apical constriction feeble, surface densely 

 punctate; scales ovate, acutely pointed behind, subcontiguous but not 

 entirely concealing the punctures. Elytra about one-third wider than 

 the prothorax, humeral angles moderate, sides parallel in basal half, 

 striae and punctures moderate, intervals nearly flat, minutely rugulose, 

 scarcely shining. Ventral surface moderately densely scaly, the scales 

 narrower than at the sides of the sterna, becoming hair-like at the 

 middle of the fourth segment, the flfth truly pubescent. All the thighs 

 armed with a small acute subspiniform tooth, less obvious but quite 

 distinct on the posterior pair. Length, 3-3.2 mm. ; width, 1.4-1.6 mm. 



Type. — cf. Huachuca Mountains, Arizona (cf 9); Havre, 

 Montana, one cJ" collected by Professor Wickham is appar- 

 ently identical. 



Closely related to iectiis, but differing in its longer second 

 funicular joint and denser vestiture. It is still nearer to 

 heterothecae Pierce, but is much larger and more conspicu- 

 ously vittate than a specimen of the latter kindly sent me 

 by Mr. Pierce. This specimen is 2,2 mm. in length, and this 

 is the length given by Mr. Pierce in his description. In 

 tectus the second funicular joint is normally short, very dis- 

 tinctly less than twice as long as wide and much shorter than 

 the two following united. 



A. tectus Lee. 



Dietz records as the habitat of this species — Arizona, New 

 Mexico, Colorado and Utah. He has certainly confused two 

 or more species under this name, none of which perhaps are 

 the real techis, the unique type of which is from Massachu- 

 setts. In the original description Massachusetts and Georgia 

 are given as localities, but the representative from the latter 

 region is not now in the LeConte cabinet ; possibly it inay 

 be in the Horn Collection. The western limits of this spe- 

 cies are as yet undetermined. Specimens from Belvidere, 

 Kansas, sent me by Mr. Knaus are very close indeed to typi- 

 cal tectus and I so place them, but the probability is great 

 that specimens from the Rocky Mountains and further west 

 are not identical with the New England type. Tectus has 

 been taken in numbers in recent years at Tyngsboro, Mass., 

 by Mr. Blanchard, who found it on wild asters (Diplopop- 

 pus) in September.
