60 COLEOPTERA RHYNCHOPHORA. 



ate in basal half ; apical constriction broad ; surface densely rather 

 coarsely punctate, moderately shining when denuded. Elytra very 

 slightly wider at base than the prothorax, twice as long as wide and 

 three times as long as the prothorax ; sides subparallel and feebly 

 arcuate in basal two-thirds ; striae moderately strongly punctured. Fe- 

 mora unarmed ; hind tibiae not appreciably curved in the cf ; claws 

 simple. Length, 1.5-1.75 mm. ; width, .6-. 65 mm. 



Albuquerque, New Mexico (type cf); Las Vegas, New 

 Mexico ; Williams and Walnut, Arizona ; the latter from 

 Prof. Wickham. 



In the 9 the beak is considerably longer and more slender, 

 the antennae inserted scarcely perceptibly behind the middle. 

 The last ventral is about one-half longer than the preceding 

 in the d^, scarcely longer than the preceding in the 9, in 

 which it bears a median rounded impression. 



This species is strikingly similar to A. tenuis described 

 above, and with it is often held in collections as wa;^/«, which 

 name, indeed, it has borne in my collection for many years. 

 The simple claws of course will at once separate it from 

 both tennis and nanus. In temiis the antennae are inserted 

 distinctly beyond the middle of the beak in the cf. E. 

 nanulus is a close relative of the present species and from 

 the same type locality. It differs in its sparser vestiture, 

 the scales less broadly rounded, the relatively greater width 

 of the elytra as compared with the prothorax, and the black 

 or piceous legs and antennae. 



E. canoides n. sp. — Very like the preceding but larger, elytra at 

 base nearly one-third wider than the prothorax, abdomen clothed 

 medially with sparser narrower scales, the latter becoming hair-like on 

 the last segment, which in the c? is nearly as long as the two preced- 

 ing. Front thighs with a small spiniform tooth ; hind tibiae distinctly 

 though not very strongly curved in the cf. Length, 2-2.15 mm.; 

 vi^idth, .8-. 85 mm. 



Type. — cf ; from El Paso, Texas; two c?'s, two 9 's. 



E. niodicus n. sp. — Piceous, legs and beak rufotestaceous, an- 

 tennae pale at base, gradually infuscate outwardly ; vestiture whitish 

 throughout, consisting of moderately broadly oval lanceolate scales on 

 the prothorax, oblong and truncate on the elytra, moderately dense 

 but not often overlapping except more or less so in three thoracic 

 vittae and in the condensed lines occupying the greater part of the
