58 COLEOPTERA RHYNCHOPHORA. 



of the beak. Antennae inserted at about the apical two-fifths of the 

 beak ; funicle G-jointed, second joint a little longer than the third, this 

 slightly longer than the fourth. Prothorax moderately transverse, the 

 sides broadly arcuate and convergent anteriorly, apical constriction 

 broad and feeble, punctuation strong and dense. Elytra four-fifths 

 longer than wide, one-fifth wider than the prothorax, sides straight 

 and parallel for more than half their length, apex rather narrowly 

 parabolically rounded ; striae moderate, rather coarsely punctate 

 basally, the intervals slightly convex. Femora unarmed ; hind tibiae 

 sinuate interiorly but not visibly bent ; claws armed with very short 

 but finely acuminate basal teeth which are not approximate at tips. 

 Length, 2.15 mm. ; width, .8 mm. 



Type. — From Ensenada, Lower California. A single cf 

 specimen. 



The derm throughout is brownish in color and may possi- 

 bly indicate immaturity. The last ventral segment is but 

 little shorter than the two preceding united. Although the 

 hind tibiae are not visibly bent, the general aspect is that of 

 Cnemocyllus and its place is apparently near ligatus, which 

 Dietz placed in this subgenus for like reasons. 



According to Dietz the claws in legahis are armed with a 

 short obtuse tooth, and the elytra show a dark "denuded 

 fascia" extending from the sides to the fourth interspace; 

 the elytra are also both by description and in the figure more 

 nearly equal to the prothorax in width than in the present 

 species. In an El Paso, Texas, specimen which I have con- 

 fidently determined as ligatus, after comparison with the 

 Deitz Collection, the vestiture is very dense, the scales more 

 or less overlapping throughout. 

 A. canusLec, A. affiuis Lee, A. nanus Lee. 

 After repeated and careful examination of the types of 

 these three supposed species I am pretty well convinced that 

 they constitute but a single species. They are all from the 

 same source and very probably from the same locality, and 

 there appear to be absolutely no differences except size and 

 relative length of the second funicular joint. The LeConte 

 Collection contains the following representatives.

 rather feebly nearly evenly curved, second funicular joint as
