1. Amblystira fuscitarsis, n. sp. (Tab. II. figg. 21,2; 22, the body 
beneath, ¢ .) 
Moderately long, the pronotum shining, the elytra opaque ; black, the elytra with nearly the apical half, and 
a narrow space on the costa just below the base, hyaline, the inner nervures on the apical portion black 
or fuscous and the others testaceous or yellow ; the antenne flavo-testaceous, with the apical joint in great 
part black ; the legs flavo-testaceous, with the apical joint of the tarsi fuscous or black, this colour some- 
times extending on to the apices of the tibie. Head rugulose; antenne slender, moderately long, 
joints 1 and 2 short, equal, 3 elongate, 4 four times as long as 2. Pronotum transversely convex, rapidly 
narrowing forwards and slightly constricted in front; coarsely, closely punctate and tricarinate, the 
median carina extending to the apex of the long, triangular, posterior portion and becoming very 
prominent behind, the outer carinz short and extending very little beyond the posterior portion. Elytra 
narrowing from the middle and rounded at the apex; discoidal area flat, elongate-triangular, not reaching 
the middle, the nervures surrounding it not or very slightly raised ; discoidal and subcostal, and part of 
the costal and sutural, areas with minute punctiform areole, the rest of the elytra with very large 
tetragonal or pentagonal areole ; costal area very narrow to about the middle and not nearly reaching 
the apex. 
Length 21-23, breadth 1-14 millim. (¢ 9.) 
Hab. Guatemata, E] Tumbador, Cerro Zunil, Volcan de Atitlan (Champion); Panama, 
Pefia Blanca (Champion). 
Eleven specimens, all from the Pacific slope. Smaller and less elongate than 
A, pallipes, Stal, the type of which is before me ; the head without interocular carine ; 
the pronotum less constricted in front, with the outer carine short and the triangular 
posterior process pointed; the elytra shorter, narrowing from the middle, with the 
nervures surrounding the discoidal area scarcely raised and the costal area not reaching 
the apex. The male has a pair of prominent curved pincer-like processes at the end 
of the abdomen. A male and female from Volcan de Atitlan are figured. 
2. Amblystira opaca, n. sp. (Tab. II. fig. 23.) 
Narrow, moderately long, dull; black, the elytra with an elongate space on the costal area a little beyond the 
middle whitish hyaline, and the large areole on the apical third fusco-hyaline; the antenne flavous, with 
the apical joint in great part black; the legs flavous, with the apical joint of the tarsi fuscous. Head 
rugulose; antenne slender, moderately long, joints 1 and 2 short, 2 a little shorter than 1. Pronotum 
transversely convex, rapidly narrowing forwards and slightly constricted in front; coarsely, closely 
punctate and unicarinate, the carina not reaching the apex of the triangular posterior portion, this being 
somewhat obtuse at the tip. Elytra moderately long, bisinuate on the costal margin, and broadly 
rounded at the tip; discoidal area short, flat, the nervures surrounding it feebly raised; discoidal and 
subcostal areas, and the sutural area in part, closely reticulated, the apical third of the elytra and the
