APIOMERUS. 239 
Sent in plenty from Teapa. Very like A. subpiceus, Stal, and similarly coloured ; but 
smaller and less elongate, the membrane in light-coloured specimens usually with 
scattered darker spots. 
The males have the two spines at the apex of the last genital segment rather short, 
upwardly curved, moderately divergent, and widely separated at the base, and the apical 
margin of this segment is subangulate on each side opposite the points of insertion of 
the claspers; the latter are comparatively short. The genital spines of the male are 
shorter, less divergent, and more widely separated at the base than in the same sex of 
A, subpiceus. 
10, Apiomerus longispinis, n. sp. (Tab. XIV. figg. 18,¢; 18a, 183, last 
genital segment, ¢ .) 
Moderately robust, shining, black, the corium and posterior lobe of the pronotum sometimes obscure reddish- 
brown, the membrane uniformly fuscous or nigro-fuscous, the nervures of the latter usually ochreous at 
the base, the connexival sutures indicated laterally by a rufous or ochreous mark, the antenne varying 
in colour from black to ferruginous ; the anterior and intermediate femora, trochanters, and coxe some- 
times flavous beneath, and the posterior tibis: and tarsi sometimes in great part ferruginous; the body 
rather sparsely clothed with erect blackish sete and also with short decumbent pallid pubescence; the 
legs somewhat sparsely setose. Antenne with joints 1 and 2 equal in length, 3 nearly twice as long 
as 2, 4 slightly shorter than 3. Pronotum with the base feebly sinuate on each side near the hind 
angles. LElytra longer than the abdomen in both sexes. Legs moderately stout, the femora feebly 
swollen before the tip. 
3S. Terminal genital segment armed with two very long, stout, tapering, upwardly curved, divergent spines ; 
the claspers long and stout, and abruptly bent inwards towards the tip. 
©. Posterior tibia sinuous before the apex, and with a dense brush of short bristly hairs on the upper edge 
beyond the middle; venter densely pilose. . 
Length 153-194, breadth 53-7} millim. 
Hab. Mexico (Boucard, in Mus. Holm.; coll. Signoret, in Mus. Vind. Ces.), Ciudad 
and Milpas in Durango (Forrer), Tepic (Schumann), Amula in Guerrero (H. H. Smith), 
Cuernavaca (Bilimek, in Mus. Vind. Ces.). 
Fourteen specimens. Very like A. subpiceus, Stal, but usually much darker in 
colour, and with the two spines at the apex of the terminal genital segment of the 
male much more elongate. These spines are longer than in any of the other species 
of the genus known to me; they are stout at the base and taper towards the tip. In 
the general shape of the terminal segment the present species agrees with A. subpiceus, 
both differing from A. tristis in this respect. The specimens belonging to the Vienna 
Museum were sent to me as A. mestus, Stal; the one in the Stockholm Museum was 
separated as a distinct species.

segment, 3.)
