330 HEMIPTERA-HETEROPTERA. 
1. Melanocoris obovatus, n. sp. (Tab. XIX. fig. 27 *.) 
Entirely opaque, clothed with a fine scattered silvery pubescence, which is serially arranged on the elytra, the 
antenne and legs finely pubescent; black, the elytra with the embolium and cuneus at the sides, the inner 
apical angles of the corium, and the transverse plica, obscure ferruginous, and the membrane fuscous; the 
second antennal joint, the tibie, and the base of the tarsi ferruginous, the third antennal joint piceous. 
Pronotum with the sides obliquely converging from the base, the two lobes separated by a faint transverse 
depression, the surface transversely rugulose. Elytra with indications of very fine, shallow, obsolete 
punctures. 
Length 3, breadth 13 millim. (?.) 
Hab. Guatema.a, Totonicapam between 8500 and 10,500 feet (Champion). 
One specimen. 
Division XYLOCORARIA, Reuter. 
This section of Anthocorine, following Dr. Reuter’s system of classification, includes 
a heterogeneous assemblage of genera agreeing in a single character only, viz. the 
absence of a hamus in the cell of the wings. ‘This character, in one genus at least, 
Scoloposcelis, is a variable one. In Solenonotus the antenne have the third and fourth 
joints very slender and clothed with long projecting hairs, as in the species of 
Lyctocoraria.

A very widely distributed genus, including fifteen described species, seven of which 
are American. Four are known to me from within our limits. Its chief characters 
are the very deeply emarginate base of the pronotum, the slender and somewhat 
fusiform third and fourth joints of the antenne, the transversely sulcate scutellum, and 
the absence of a hamus in the cell of the wings: these points of distinction will serve 
to separate the species from the various very similar Lastochili and Asthenidee. 
a. Elyra rather sparsely punctate ; the embolium narrow, at the apex about 
half the width of the corium: body oblong-ovate.

rugulose Se
