Not uncommon in the Mexican State of Vera Cruz. In this species the corium and 
the posterior lobe of the pronotum are usually brownish or piceous, rarely black. The 
legs vary in colour from piceous, with the hind tibie (the base excepted) ferruginous 
or testaceous, to entirely black. The antenne in some specimens are ferruginous, and 
in others almost entirely black. The membrane is uniformly fuscous. The males 
have the apex of the last genital segment broadly produced in the centre and armed 
with two moderately long, widely divergent, upwardly curved spines; the claspers are 
long and somewhat abruptly bent inwards towards the apex. 
8. Apiomerus tristis, n. sp. (Tab. XIV. figg. 15,3; 15a, 154, last genital 
segment, ¢ .) 
Robust, black, the posterior lobe of the pronotum piceous in the middle and the anterior femora flavescent 
beneath at the base in one specimen ; the membrane fusco-testaceous, mottled with blackish, the two inner 
cells dark at the base, the apical portion paler and subhyaline, the nervures at the base, as well as those 
on the inner portion of the corium in one specimen, ochreous; the connexival sutures indicated laterally 
by an ochreous mark; the antenne and basal joints of the tarsi ferruginous ; the body thickly clothed 
with erect blackish sete: and also with short decumbent pallid pubescence; the legs thickly setose. 
' Antenne with joint 2 slightly longer than 1, 3 nearly twice as long as 1, 4 a little shorter than 3. 
Pronotum with the base feebly sinuate on each side near the hind angles. Elytra extending to far beyond 
the abdomen in both sexes. Legs stout, the femora slightly swollen before the tip. — 
3. Terminal genital segment strongly transverse, armed with two widely separated, moderately long, upwardly 
curved, divergent spines, the apical margin with a short tooth on each side above the points of insertion of 
the claspers (appearing emarginate laterally); the latter comparatively short and stout, and abruptly bent 
inwards beyond the middle. 
©. Venter thickly pilose. 
Length 163-18, breadth 6-74 millim. 
Hab. Mexico, Tepic (Schumann). 
One pair. Very like A. subpiceus, Stal, but differing from it in the more thickly 
setose body and the distinctly mottled membrane; the male is more robust than the 
corresponding sex of that species, and it has the terminal genital segment more trans- 
verse and the armature different—the two spines are more widely separated at the base, 
the apical margin is angularly dilated or toothed above the points of insertion of the 
claspers, and the claspers themselves are shorter and more abruptly bent inwards 
beyond the middle.
