10 HEMIPTERA-HOMOPTERA. 
APATESON, gen. nov. 
Elongatum, angustum, parallelum, cylindricum, vertice brevissimo, antice carinato, fronte longa, excavata, 
suturé clypeali indistincta, lateribus valde elevatis, carinatis ; oculis prominulis, ocellis distinctis ; pronoto 
brevissimo, antice rotundato; scutello prelongo, sat fortiter tricarinato; tegminibus opacis, sat corneis, 
angustis, parallelis, venis vix elevatis, vend radiali a basi, vena ulnari a medio furcaté; margine costali 
ad apicem venis quibusdam transversis instructo; alis opacis cum tegminibus concoloribus ; tibiis posticis 
unispinosis. 
Elongate, narrow, and parallel, with the vertex very short, elevated at the sides between the eyes, which are 
‘prominent ; ocelli distinct, between the eye and the margin of the frons; frons and clypeus divided by 
an indistinct suture, apparently forming one long piece, which is excavate and strongly carinate at the 
sides ; pronotum very short, rounded in front; scutellum long, tricarinate; tegmina long, narrow, and 
parallel, somewhat convex, with the veins not strongly marked, the radial vein being forked from the 
base, and the ulnar vein from the middle; the costal margin at the apex has about nine or ten transverse 
veins, not set very close together ; wings dark, concolorous with the tegmina; posterior tibia unispinose, 
I have referred this genus to the Ricaniine, as the ridge dividing the vertex and 
frons is distinct, but I do not feel sure as to its position. 
1. Apateson albomaculatum, sp.n. (Tab. VIII. figg. 15, 15a.) 
Nigrum, cylindricum, fronte et clypeo albido-marginatis ; scutello ad basim maculis duabus albidis instructo ; 
tegulis, postscutello, et decem maculis tegminum albescentibus ; apice tegminum hyalino ; abdomine nigro 
vel fusco, pectore pedibusque infuscatis; alis nigrescentibus, opacis; pedibus spina un& pone medium 
instructis. 
Black, with the front edged with white; on each side of the scutellum, touching the margin towards the base, is a 
white spot; the tegule are large and white, and the postscutellum is wholly or partly of the same colour ; 
the tegmina are long, narrow, and parallel, with six white spots (three on each side) at the suture, the 
hinder pair being transverse, an irregular oblique white spot on the disc towards the base, and a spot 
on the costal margin beyond the middle; the apex of the tegmina exteriorly is hyaline, the hyaline 
portion being crossed by a transverse dark band, and the apex itself is dark ; wings opaque fuscous-black ; 
posterior tibiee with one spine a little behind the middle. 
Long. 11-12 millim.; lat. 3 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith), Valladolid in Yucatan (Gaumer) ; 
Nicaragua, Chontales (Mus. Brit.); Panama, Bugaba (Champion). 
The specimen figured is from Teapa. 
Fam. DERBIDA*. 
The members of this family are chiefly noted for the development of the antennae, 
which is very marked in certain genera ; the posterior tibie are usually simple. They 
differ considerably inter se in general appearance, but are, for the most part, very 
delicate insects, some bearing a close resemblance to certain Lepidoptera and 
Neuroptera. 
The position of the group is somewhat doubtful: Spinola regards the * Derboides” as
