60 HEMIPTERA-HETEROPTERA. 
femora usually blackish or fuscous, the sides of the ventral segments sometimes stained with fuscous ; 
above and beneath, the basal joints of the antenna, the coxw# and femora, and the two hinder tibize, 
studded with small smooth granules, these (owing to their pale colour) forming variegate markings on the 
scutellum ; the posterior portion of the pronotum, the scutellum, and corium rather closely punctured, 
the punctures on the pronotum and on the base of the scutellum moderately coarse, the others fine. 
Antenne moderately stout, joint 4 about as long as 2 and 3 united, 3 neurly twice as long as 2. 
Pronotum feebly convex behind, slightly depressed along the middle, the lateral angles obliquely truncate ; 
_ the two dorsal carine reaching the anterior lobe, converging anteriorly, and evanescent behind. Scutellum 
constricted below the base, with a smooth prominent median carina. Corium with the median nervure 
extending obliquely inwards. Abdomen oval, the connexivum moderately wide, the apex of each of the 
segments slightly projecting laterally, that of the first and fifth subangularly dilated. 
Q. Broader; above pale brown, the basal joints of the antenne and the head (except at the sides behind) 
fuscous, the pronotum, scutellum, and corium also mottled with darker brown; the connexivum much 
more broadly dilated at the sides, the first and sixth segments subangularly dilated laterally at the apex; 
the apical joint of the antenne a little shorter, more ovate in shape, and more pointed at the tip. 
Length 81-94, breadth ¢ 3-3}, 2 4 millim. 
Hab. Guatemaa, Purula, Sabo, and Sinanja in Vera Paz (Champion '). 
Var. Above and beneath very sparsely, minutely granulate, the scutellum closcly, finely, uniformly punctate, 
the connexivum more evenly rounded at the sides, the first and sixth segments not subangularly dilated 
at the outer apical angle. (9.) 
Hab. Mexico, Omilteme in Guerrero (H. H. Smith 1). 
Six males and one female of the typical form have been obtained. The variety is 
represented by an imperfect female example. The male of M. granulatus may easily 
be known by its variegate colour, the segments of the connexivum being spotted and 
the pale granules on the scutellum forming definite markings. The female, as in 
M. lepidus and others, is much paler and more uniformly coloured. The long third 
joint of the antenne is a conspicuous character in the present species. ‘The insect is 
unknown to Herr Handlirsch.

(antenna). 
3. Very elongate, narrow, narrowing posteriorly; fuscous, the pronotum mottled with lighter brown; the 
scutellum and corium blackish, fuscous at the base, the scutellum with an apical spot and a transverse 
patch in front of it sordid yellow, and also slightly mottled with the same colour; the antenne rufo- 
fuscous, with the apical joint black; the legs, including the coxe, the sterna, and a broad space down the 
middle of the abdomen beneath, flavous, the tibia and tarsi suffused with green; the exposed portion of 
the connexivum ochraceous; the upper surface, the basal joints of the antenne, the coxse and femora, and 
the two hinder tibie, studded with small smooth scattered granules; the posterior portion of the pronotum 
and the basal half of the scutellum sparsely and coarsely, the rest of the scutellum closely and finely, 
punctate. Antenne stout, joint 4 ovate, nearly as long as 1-3 united, 2 and 3 subequal. Pronotum with 
the lateral angles convex and excised, the anterior tooth rather sharp and prominent, the posterior one 
obtuse ; the two dorsal carinw short, slightly converging in front, and reaching the long anterior lobe. 
Scutellum gradually narrowing from the middle forward, with a smooth median carina, which becomes 
less distinct towards the base. Abdomen gradually narrowing from the base, the connexivum scarcely 
visible from above; the ventral segments with a broad, smooth, shining space down the middle, the 
sides closely granulated. 
Length 92; breadth 24, of the pronotum 3 millim.
