the sides narrowly explanate and feebly sinuate in $. Elytra wider 

 than the prothorax in both sexes, faintly costulate on the disc. 

 Inner claw of anterior tarsi broadly lobed, and the outer claw of the 

 other tarsi cleft at the tip, in ^. 



(J. Eighth ventral segment rapidly narrowed to the rounded apex, 

 carinate down the middle; ninth segment (so far as visible) appar- 

 ently shaped as in D. plicatum. 



Length (excl. head) 7f-7i, breadth 2J-3 mm. (cj $.) 



Hab. Mexico, Ventanas in Durango (Hoge). 



One pair. This insect is very closely allied to D. plicahim, 

 which also occurs in Durango ; but the extremely long, 

 slender, densely pilose antennae, the much smaller eyes, 

 and the narrow general shape of the male forbid any associa- 

 tion with that species.

Elongate, rather narrow {^), broader ($), moderately shining, 

 finely cinereo-pubescent, the prothorax with longer hairs ; black, 

 the head in front, the basal joint of the antennae in part or wholly, 

 the base of the mandibles, the prothorax (a median vitta or spot 

 excepted), and often the sutural and outer margins of the elytra, 

 and the apex or outer margin of the abdomen, flavous, the disc of the 

 jirothorax in some specimens rufescent on either side of the median 

 vitta. Eyes rather small in both sexes. Antennae rather stout, 

 subserrate, tapering towards the tip, sparsely pilose, shorter in $. 

 Prothorax transverse, as broad as, or broader than, the base of the 

 elytra; the sides angularly notched at about the basal third in (J, 

 and explanate and deeply sinuato-emarginate at the same place in $, 

 in fully developed specimens arcuato-ampliate before the middle. 

 Elyti-a long, not explanate at the sides. Sixth ventral segment 

 deeply triangularly emarginate at the apex in ^, the seventh 

 segment long, with the median fissure widening anteriorly. Inner 

 claw of anterior tarsi broadly lobed, and the outer claw of the 

 other tarsi cleft at tip, in (^. 



Var. a. Prothorax, and usually the scutellum, humeri, sutural 

 and outer margins of the elytra, the femora at the base or entirely, 

 and the tibiae in part, testaceous or flavous.

 middle, the two portions appearing broadly, conjointly rounded,
