CINYPHUS. 89 
Mexico; this latter differs from the others, and also from the type (2), which is 
now before me, in having the outer apical angles of the connexival segments a little 
more dilated. The tibie are more or less distinctly annulate. We figure a male 
from Zapote. 
2. Cinyphus subtruncatus. (Tab. VI. figg. 16, ¢; 17,2.) 
Cinyphus subtruncatus, Bergr. Bull. Mus. Paris, 1898, no. 8, p. 149°. 
Elongate-triangular, nigro-fuscous or black, the tips of the antenne and the outer apical angles of the connexival 
segments ochraceous, the tibisz usually annulated with ochraceous, the tarsi fuscous or fusco-testaceous, 
the membrane obscure luteous at the base; the upper surface granulate, the connexival segments simply 
punctured, and sparsely clothed with very short, decumbent, rusty-brown hairs. Head subquadrate, longer 
than broad (exclusive of the apical process) ; the apical process long, unarmed at the sides, terminating in 
two stout lobes; the antenniferous processes long and stout, spiniform, and slightly divergent; the post- 
ocular portions dilated into an acute tooth, not extending so far outwards as the eyes, which are rather large 
and prominent; antenne moderately elongate, joints 1 and 3 subequal in length, 1 extending to far beyond 
the apical process of the head, rather stout, asperate, and clothed with short curled hairs, 2 shorter than 3 
and a little longer than 4, thickened at the tip. Pronotum transverse, deeply emarginate at the base, the 
sides constricted at the middle; the anterior portion with two tubercles on the disc; the anterior angles 
lobiform and extending forwards, concave in front, and rounded and coarsely crenate externally; the 
posterior portion moderately dilated, the sides crenulate, parallel behind, and rounded or subangularly 
projecting anteriorly. Corium sinuate externally and deeply arcuate-emarginate within, the apical 
margin obliquely truncate. Abdomen widening from the base, slightly rounded at the sides before the 
middle, very broadly and abruptly truncate at the apex ; the outer apical angles of segments 1-4 angularly 
projecting, that of the fifth segment rounded; the sixth segment with a short prominence at about the 
middle of the apical margin of the connexivum on each side, raised in front of the genital segments in the 
male and with two short transverse elevations in the centre in the female; the genital lobes short and 
stout in the female, more slender in the male. Beneath opaque, the ventral segments thickly, finely 
punctate, each with a small smooth spot in the middle. Legs rather elongate; the femora moderately 
stout, asperate, and shortly setose. 
Length 9-11, breadth 4-54 millim. (d 9.) 
Hab. Nicaraeva, Chontales (Janson); Panama, Volcan de Chiriqui, Caldera (Cham- 
pion).— VENEZUELA}. 
Found in numbers in Chiriqui, singly at Chontales. Allied to C. emarginatus, Stal, 
but more sharply triangular in shape, this being especially noticeable in the females ; 
it also has the corium more acute at the apex. The anterior angles of the pronotum 
have from 3-5 blunt teeth on the outer edge; and the posterior lobe is sometimes 
crenate or subangulate at the sides anteriorly. We figure a pair from Chiriqui. 
3. Cinyphus squalidus, n. sp. (Tab. VI. fig. 18, ¢.) 
3. Oblong, widening behind, broad, nigro-fuscous, the outer apical angles of the connexival segments 
ochraceous, the tibie and the three outer joints of the antenne inclining to ferruginous; the surface 
coarsely granulate, the connexivum coarsely punctured, and somewhat thickly clothed with very short, 
decumbent, rusty-brown hairs. Head subquadrate; the apical process long and stout, bilobed at the tip, 
about one-third shorter than the first antennal joint; the antenniferous processes stout, subparallel, 
terminating in a short blunt spine; the post-ocular portions angular just behind the very prominent eyes 
and obliquely converging thence to the base; antennz moderately long, joints 1 and 3 subequal in length, 
1 rather stout, hispid, and asperate, 2 a little shorter than 3, and considerably longer than 4, thickened
