1. Holomallus aurivillus. 

 Holomallus aurivillus, Gorh., loc. cit. p. 326. 



(J. Tibiae with two short stout spurs; fifth ventral segment 

 broadly truncate at the apex, leaving the long, excavate, sixth 

 segment exposed. 



Hab. Mexico, Puebla. 



2. Holomallus serripes, n. sp. (Plate II, fig. 20, ^, 

 anterior tibia.) 



(J. Oblong-ovate, rather convex, the head and prothorax opaque, 

 the elytra somewhat shining ; nigro-piceous, the elytra reddish-brown 

 or aeneo-piceous, the antennal joints 2-6 and the legs ferruginous 

 or fusco-ferruginous ; thickly clothed with rather long, coarse, 

 pallid, shaggy, decumbent hairs, the head and prothorax with inter- 

 mixed erect hairs, the marginal cilia of the elytra long, curled, and 

 closely placed. Head small, short, densely, finely, rugulosely 

 punctate; antennae short, the five outer joints widened into an 

 elongate club, 7-10 strongly transverse, 9 and 10 wider than 8, 

 11 short-ovate, narrower than 10, 5 not larger than 6. Prothorax 

 strongly transverse, broad, greatly rounded at the sides, narrowing 

 from near the base, the latter sinuate; densely, finely punctate. 

 Elytra broad, somewhat oval, the humeri not prominent, the lateral 

 carina conspicuous ; densely, moderately finely punctate. Fifth 

 ventral segment truncate at the tip. Legs rather stout; tibiae 

 closely and strongly spinose along their outer edge (fig. 20), the 

 anterior and intermediate pairs with two short, stout, approximate 

 spurs. 



$. Narrower, the prothorax smaller, the elytra subparallel in 

 their basal half, the tibial spurs smaller and more slender. 



Length 4^|, breadth 1|-2|- mm. (c??.) 



Hab. Mexico (Truqui, in Mus. Brit. ; Mus. Oxon.). 



Thirteen specimens. Very like the unnamed abraded 

 Holomallus ($) from Puebla mentioned by Gorham (loc. cit. 

 p. 326) ; but with the vestiture almost wholly decumbent, 

 except on the head and prothorax, the elytra much more 

 finely punctate, etc. The Puebla insect is too worn to 

 describe. H. aurivillus is thickly clothed with extremely 

 long, fulvous, shaggy hairs.
