LISTRONOTUS.—HYPERODES. 12] 
from the base, conjointly rounded at the apex, the base shallowly emarginate, the humeri broadly and 
obliquely subtruncate ; finely punctate-striate, the interstices rugulose and almost flat, the fifth feebly | 
callose towards the apex. Beneath closely punctate, with scattered intermixed coarser punctures. Venter 
strongly depressed down the middle of the first two segments in the ¢. 
Length 5-63, breadth 2-23 millim. (¢ 9.) 
Hab. Muxtco, near the city, probably from the banks of the large lakes (Hoge). 7 
Eleven specimens. Very like the North-American LZ. latiwsculus (Boh.), but with 
longer sete on the elytra (these not being at all clubbed) and the seriate punctures 
on the latter not so coarse. 
2. Listronotus —— ? 
Hab. Mexico, Vera Cruz (Hége). 
A single female specimen, too worn for description. This insect is very like 
L. bagoiformis, but differs from it in having the rostrum distinctly carinate, the elytra 
piceous in colour, very coarsely seriate-punctate, with the interstices convex and sparsely 
rugulose, the under surface more coarsely punctured, and the tibie ferruginous.

Thirty-three species of this North-American genus are recognized by Dietz. Three 
are represented in our collections, one extending southward to Panama, two of them’ 
being here treated as new. The generic name Macrops is preoccupied in Reptilia 
and Rhynchota, 
1. Hyperodes hirtella. 
Macrops hirtelius, Dietz, Trans. Am. Ent. Soc. xvi. p. 46 (1889) '. 
Elongate-ovate, shining; varying in colour from black to ferruginous, pale specimens sometimes having a 
common black patch on the elytra or a longitudinal black vitta on the disc of each of them; the upper 
surface with scattered, coarse, erect, blunt sete, and when fresh clothed with large, rounded, loosely 
attached griseous or brownish scales, which tend to form vitte on the prothorax and irregular spots on 
the elytra; the legs setose. Head and rostrum densely, rugulosely punctate; the latter short and stout, 
dilated at the apex, shallowly foveate at the base, and more or less distinctly tricarinate ; joints 1 and 2 
of the funiculus subequal in length, 1 stouter than 2. Prothorax transverse, rounded at the sides, 
coarsely, densely punctate. Elytra one-half wider than the prothorax, slightly hollowed at the base, 
subparallel to near the middle, and a little produced at the tip; coarsely punctate-striate, the punctures 
closely placed, the interstices somewhat convex, shining, not wider than the strie, and each with a row 
of seta. Tarsi stout, joint 4 about as long as 1-8 united. Fifth ventral segment shallowly foveate 
in the @. 
Length 3-4 millim. (¢ 2.)
