HETEROMERA. 511 
without marginal carina; epipleure abruptly widened at the base, faintly punctured, hairy; prosternum 
strongly produced, margined at the apex. 
Length 73-9, breadth 43-52 millim. . 
Hab. Muxico, Villa Lerdo in Durango (Hoge). 
Many specimens. This insect nearly agrees with the description of E. puberulus, 
Lec., from Texas, but Dr. Horn, to whom I have submitted an example, informs me 
that it is distinct. ZH. obsoletus is the smallest of the Mexican species; it is more 
parallel and much narrower than E. brevis, and has the prosternum margined at the 
apex. ‘The scale-like hairs on the elytra are only visible under a strong lens and are 
easily abraded. |

2 (a). Eleeodes macrura. 
dg. Very elongate, convex, subfusiform, black, moderately shining. Head sparsely, minutely punctate, the 
punctures much coarser on the anterior part; prothorax convex, broader than long, a little narrowed in 
front and behind, slightly broader at the base than at the apex, very feebly carinate at the sides (the 
carina scarcely visible from above), the anterior angles sharply produced and slightly everted, the surface 
exceedingly minutely, sparsely punctate; elytra strongly caudate, including the caudal prolongation more 
than four times as long as the prothorax, gradually widening to about the middle and then obliquely con- 
verging behind, with rows of very fine approximate punctures, the interstices feebly convex on the disc, 
perfectly flat at the sides, and each with a row of distantly placed, submuricate impressions, which are 
coarser than those of the strie ; anterior femora armed with a sharp, slightly curved, strong tooth on the 
inner side, and emarginate between this and the apex ; anterior tibiee emarginate on the inner side at the 
base; posterior tibize feebly sinuous. 
Length (including cauda) 34, breadth 12 millim. 
Hab. Mexico, Villa Lerdo in Durango (Hége). 
One example. More elongate and more fusiform than the same sex of Z. ventricosa ; 
the prothorax more convex, and with a very feeble lateral carina; the elytra witha 
series of distantly placed submuricate punctures upon each interstice, these punctures 
coarser than those of the strie. 
Elzodes spinipes (p. 77). 
To the Mexican localities given, add:—Zimapan, Tula, and Ixmiquilpan in 
Hidalgo (Hége). 
Var.? Less ventricose; the elytra flatter, with rows of more distantly placed punctures, the interstices flat, each 
with a row of finer, more scattered impressions. 
Hab. Mexico, Chihuahua city, Durango city, Aguas Calientes city, Lagos (Hége), 
Guanajuato (Flohr, Sallé).
