PARATRIPHLEPS.—MELANOCORIS. 329 
has been obtained, is evidently a near ally of Triphleps perpunctatus, Reut., &c.; but 
the laterally margined pronotum, and the very deeply emarginate base of the latter, 
exclude it from Triphleps. 
If the insects from Grenada and St. Vincent which have been determined by 
Prof. Uhler as the Antillean Brachysteles pallidus, Reut., are correctly named, that 
species would probably have to be included in Paratriphleps, the wings having a hamus 
in the cell. 
1. Paratriphleps leviusculus, n. sp. (Tab. XIX. fig. 26.) 
Rufo-testaceous, shining, the eyes black, the rostrum, the anterior margin of the pronotum, and the tip of the 
scutellum piceous, the posterior lobe of the pronotum slightly infuscate behind; the elytra flavescent, 
mottled with fuscous, the apex of the cuneus dark, the membrane hyaline ; the antenne testaceous, with 
joint 3 piceous at the apex, 4 ferruginous; tke legs flavous, the intermediate and hind tibie piceous from 
the middle to the apex. Head smooth; antenne short, not reaching the hind angles of the pronotum, 
rather slender, joint 2 slightly longer than 3. Pronotum convex, moderately narrowed anteriorly, the 
sides slightly sinuate at the middle and rounded in front; the anterior lobe smooth, the posterior lobe 
rugulose, the latter not depressed on the disc. Scutellum faintly transversely rugulose. Elytra with the 
cuneus only distinctly punctate, for the rest very sparsely, minutely, indistinctly punctate, the embolium 
slightly rounded along the outer edge. 
Length 14 millim. (9.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
This insect differs from Dr. Reuter’s description of Brachysteles pallidus, from the 
Islands of St. Thomas and St. John, in the almost smooth elytra, the smoother anterior 
lobe of the pronotum, the partly infuscate intermediate and hind tibie, &c. 
MELANOCORIS, n. gen. 
Head with the ante-ocular portion a little longer than the inter-ocular, the eyes very small, the ocelli 
minute, antennz short; joints 1 and 3 subequal in length, 2 twice as long as 1, 4 longer than 3; 
rostrum short, only reaching the anterior coxe. Pronotum short, along the median line not quite so long 
as the head, rounded at the sides anteriorly and deeply emarginate at the base, the anterior lobe scarcely 
callous on the disc, and without a distinct collar in front. Scutellum flattened behind. Elytra with the 
cuneus greatly developed, about one-fifth shorter than the embolium, the membrane with four prominent 
nervures. Metasternum broadly rounded behind. Legs comparatively short; tarsi 3-jointed. Posterior 
coxe widely separated. Orifice of the metastethium short, backwardly curved. Body broadly obovate, 
opaque, the entire upper surface finely rugulose, the elytra without well-defined punctures. 
This genus is allied to Tetraphleps and Acompocoris. which include various palearctic 
forms found upon pine-trees. It differs from them in having the hind coxe more 
widely separated, the antenne and legs much shorter, the pronotum without a distinct 
collar in front and the anterior lobe scarcely callous on the disc, the entire upper 
surface rugulose and opaque. The insect from which the above characters are taken 
was also, I believe, found upon pine-trees, at a high elevation, in the Los Altos region 
of Guatemala.
