314 HEMIPTERA-HETEROPTERA. 
about half the width of the corium, the membrane with three nervures, the outer one only prominent. 
Wings with the hamus issuing beyond the decurrent nervure. Orifice of the metasthethium short, 
curving forwards externally, Anterior and posterior coxe narrowly, the intermediate coxe more broadly, 
separated. Legs elongate, the femora incrassate, the tibiee clothed with long projecting hairs. Body 
oblong-obovate, pilose. 
The single species referred to this genus is allied to Lastocolpus, Reut., but differs 
from it in having the orifice of the metastethium curving forwards (instead of back- 
wards), the rostrum very much shorter, the pronotum less sinuate at the sides, the 
scutellum shining, the punctuation of the elytra subserially arranged, &c. From 
Asthenidea it may be known by the longer head and pronotum, the large eyes, the 
stouter first and second joints of the antenna, the pilose elytra, the long, hairy legs, &c. 
1. ‘Lasiocolpoides ciliatus,n. sp. (Tab. XIX. fig. 8.) 
Shining, nigro-piceous or piceous, the base of the embolium, the clavus, corium, legs, and antenn obscure 
testaceous, the membrane fuscous, flavescent towards the base; the elytra (the membrane excepted) thickly, 
the other parts more sparingly, clothed with long semierect hairs, the head and pronotum with still longer 
hairs intermixed. Head smooth, deeply bifoveate between the ocelli; antenne rather elongate, joints 
1 and 2 moderately stout, 3 and 4 very slender, 2 slightly thickening outwards, and about three times as 
long as 1, 3 and 4 equal in length, each much shorter than 2. Pronotum in front not wider than’ the 
base of the head, smooth, the posterior lobe flattened on the disc and, as well as the apex, transversely 
rugulose. Scutellum with the apical portion slightly rugulose. Elytra with the clavus, a space along the 
middle excepted, and the inner half of the corium densely subseriately punctured, the embolium also with 
a row of punctures along the inner edge. 
Length 4,443 millim. ( 2.) 
Hab. Guatemata, Quiché Mountains and San Gerénimo (Champion). 
Two specimens, one of which is imperfect. 
PLOCHIOCORIS, n. gen. 
Head longer than broad, exserted, the produced anterior portion stout, the ocelli narrowly separated; eyes 
large, oval (as seen from above), and distant from the anterior margin of the pronotum; rostrum reaching 
to the anterior coxe ; antenne elongate, joints 1 and 2 moderately stout, 1 reaching a little beyond the 
anterior process of the head, 2 cylindrical, nearly four times as long as 1, and as long as 3 and 4 united, 
3 and 4 very slender, subequal in length, 2-4 clothed with very long projecting hairs. Pronotum 
trapezoidal, short, much narrowed anteriorly, deeply transversely bisulcate on the disc, the anterior 
sulcus extending downwards across the pleura and separating off the collar in front, the anterior lobe 
also suleate down the middle, the sides immarginate and concave, the base feebly emarginate. Scutellum 
depressed behind. Elytra subparallel, elongate, extending far beyond the abdomen, clothed with very 
long hairs; embolium very narrow in its baxal half, broad behind and there nearly as wide as the corium ; 
membrane with two distinct nervures. Wings without trace of a hamus in the cell. Orifice of the 
metastethium long, transverse, nearly reaching the pleural groove, curving a little forwards externally. 
Legs rather elongate, the femora feebly incrassate, the tarsi 3-jointed. 
Following Dr. Reuter’s system of classification, this genus belongs to the Xylocoraria, 
but the antennal structure is so like that of Lasiochilus and its allies that I prefer to place 
it in the same division of the Anthocorine. The relatively very elongate second antennal 
joint and the peculiarly formed pronotum are its chief characteristics.
