MACROCEPHALUS. 59 
the anterior lobe. Scutellum gradually narrowing from the middle forwards, with a moderately prominent 
smooth median carina. Abdomen oval, very little wider than the pronotum, the connexivum rather 
narrow, the segments not projecting at their outer apical angles. 
Length 84, breadth 3 millim. 
Hab. Mexico (coll. Signoret!? 3, in Mus. Vind. Ces.); Panama, Boquete in Chiriqui 
3000 feet (Champion). | 
One example, only differing from the type (ide Handlirsch) in being a little darker. 
The description given will supplement that of Stal.

3. Very elongate, narrow; ochraceous, the head with a blackish mark between the ocelli, the pronotum with 
the posterior portion suffused with rufo-fuscous, the lateral angles fuscous, the scutellum with the apical 
half mottled with brown, with indications of a darker median fascia; the legs and corium suffused with 
green; the antenne rufo-ferruginous, the apical half of the fourth joint blackish ; above (the basal half of 
the scutellum excepted) and beneath, the basal joints of the antenna, the cox and femora, and the two 
hinder tibie, studded with small smooth granules; the posterior portion of the pronotum and the basal 
half of the scutellum coarsely, the rest of the scutellum finely and closely, punctured. Antenne 
moderately stout, joint 4 distinctly longer than 1-3 united, 2 and 3 subequal in length. Pronotum with 
the lateral angles convex and acute, these being emarginate behind; the two dorsal carinw moderately 
prominent, converging anteriorly, and reaching the long anterior lobe; the posterior portion canaliculate 
in the middle in front. Scutellum gradually narrowing from about the middle forwards, with a smooth 
prominent median carina. Abdomen subparallel, the very narrow connexivum scarcely visible from above, 
the fifth segment angularly dilated at the outer apical angles. 
Length 93; breadth 2,1,, of the pronotum 3,1, millim. 
©. Broader, the pronotum paler on the disc; the scutellum shorter, suffused with green at the sides, and with 
the dark apical patch not reaching the middle; the abdomen elongate-oval, the connexivum as wide as 
the corium and visible from above almost to the apex, the fifth and sixth segments angularly dilated at 
their outer apical angles. 
Length 1032, breadth 3, of the pronotum 33 millim. 
Hab. Nicaracua, Chontales (Janson!: 92); Panama, Volcan de Chiriqui (Cham- 
pion':3). 
One example from each locality. The ochraceous portions of the scutellum and 
corium, as well as the legs, are probably green in life. The insect is closely allied to 
M. macilentus, Westw., from Colombia, from which it differs (jide Handlirsch) in 
having the antenne much longer. :

3. Moderately elongate; above black, fuscous, or brownish, the head with a marginal stripe behind the eyes, 
the pronotum with the margins (except at the apex of the lateral angles), the dorsal caring in front, and 
a median vitta on the posterior portion, the scutellum with a narrow elongate-triangular mark below the 
base, the sides in front, and the median carina for some distance before and beyond the middle, as well as 
most of the granules, and the anterior half or more of each of the segments of the connexivum, flavous or 
ochraceous ; the antenne blackish or fuscous, the three basal joints beneath, and the base and apex of the 
fourth joint, more or less ochraceous ; the body beneath and the legs flavous or ochraceous, the anterior
