MACROCEPHALUS. 61 
One example. Easily separable from M. angustatus, 3, by the shorter and stouter 
apical joint of the antenne, and the broad, excised lateral angles of the pronotum. 
Very similar to M. macilentus, Westw., but differing from it in the emarginate and - 
more convex lateral angles of the pronotum (fide Handlirsch).

Q. Comparatively short, broad; obscure rufo-testaceous, the lateral angles of the pronotum paler, the scutellum 
with a large patch on each side at the base ochraceous and the median carina flavous in front; the 
connexivum rufo-fuscous, each of the segments bordered with black externally at the middle, and with 
the outer anterior and posterior angles testaceous; the antenns fusco-ferruginous; the legs fusco- 
testaceous, the femora reddish ; the body beneath rufo-testaceous ; above and beneath, the basal joints of 
the antennz, the coxe and femora, and the two hinder tibie, studded with smooth granules, those on 
the pronotum, scutellum, and connexivum very minute and widely scattered; the posterior half of the 
pronotum and the basal portion of the scutellum somewhat coarsely, and the rest of the scutellum 
closely and finely, punctured. Antenne short and stout, joint 4 ovate, as long as 2 and 3 united, the 
latter subequal. Pronotum rather broadly dilated at the sides, the lateral angles slightly excised (forming 
two very short obtuse teeth) and with their anterior margin feebly dilated and reflexed at the middle ; 
the two dorsal carine short, very little raised, slightly converging in front, and reaching the anterior 
lobe. Scutellum narrowing from the middle forwards, with a smooth sharp median carina, which is 
thickened at the base. Abdomen broad-oval, the connexivum wide and rounded externally. 
Length 61, breadth 3 millim. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith }), 
One example, evidently discoloured. Very like M. stali, Handl.; but differing from 
the female of that species in the much more finely punctured pronotum and scutellum, 
as well as in the shape of the lateral angles of the pronotum, these having their oblique 
anterior margin slightly dilated and reflexed at the middle. In certain lights the 
ochraceous patch at the base of the scutellum appears to be limited posteriorly by an 
oblique darker stripe. The insect is unknown to Herr Handlirsch.

Var, Pronotum more depressed behind, the anterior lobe more feebly spiculate at the sides; scutellum in the 
male sometimes entirely black, the short streak on the median carina at the base excepted. (¢ 2.)

Two species were confused by Stal under the name MM. lepidus, the name UV. stéli 
being applied to one of them by Handlirsch. Of the latter we have received numerous 
examples of both sexes from Guerrero, the males agreeing perfectly with the types of 
- M. lepidus in the Stockholm Museum, communicated by Dr. Aurivillius. Those in 
the Signoret collection, communicated by Herr Handlirsch, agree best with his
