PACHYSCHELUS CINCTUS Waterhouse. 
Pachyschelus cinctus WATERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 
1889, p. 149, pl. 8, fig. 15. 
This species was described from material collected by Mr. Champion, 
at Rio Maria Linda, Guatemala, at an elevation of 500 feet, and also 
from Volcan de Chiriqui, Panama, at an altitude of 2,000 to 4,000 
feet, without designating any definite type locality. No specimens 
of this species have been examined, and it is placed in the key solely 
upon the characters given in the original description. 
PACHYSCHELUS PILOSUS, new species. 
Female.—Broadly ovate, slightly longer than wide, more strongly 
narrowed behind than in front, subopaque, piceous, with the elytra 
narrowly violaceous along lateral margins; surface rather densely 
pubescent, the pubescence forming irregular designs on the elytra; 
beneath piceous, more shining than above. 
Head flat and deeply embedded in the prothorax, with an obsolete 
median depression on the vertex: surface rather densely punctate, 
the punctures large, shallow, and well separated, sparsely clothed with 
rather short cinereous hairs on the occiput; intervals finely, densely 
granulated. Pronotum moderately convex, nearly four times as wide 
as long at the middle, much narrower in front than behind, widest 
at base; sides strongly, obliquely arcuate from base to apical angles, 
and narrowly margined; apical angles nearly rectangular; anterior 
margin deeply, arcuately emarginate for the insertion of the head; 
base feebly, obliquely truncate to the elytral lobe, where it is 
acutely, arcuately emarginate, then transversely truncate in front of 
scutellum; hind angles obtuse, not projecting beyond the humeral 
angles of the elytra and fitting closely to them; surface feebly de- 
pressed at base, finely, densely granulated over entire surface, sparsely 
clothed with short, recumbent black and cinereous pubescence form- 
ing irregular designs. Scutellum obsoletely punctured, and glabrous, 
with the anterior angles acute. Elytra as wide as pronotum at base; 
widest at basal fourth; humeral angles obtuse; sides broadly arcuate, 
rather strongly attenuate posteriorly to the tips, which are conjointly 
rounded, the lateral margin very feebly serrate, and when viewed 
from the side, is broadly arcuate from humeral angle to apex and 
feebly sinuate just behind the middle; each elytron with a broad, 
shallow depression at the base, and a deeper one between the humerus 
and lateral margin, extending along the margin from the humeral 
angle to the middle, and becoming much broader and deeper behind 
the humerus; surface finely, densely punctate, becoming somewhat 
rugose toward the sides, and sparsely, irregularly clothed with rather 
short recumbent cinereous and black pubescence, the black pubes- 
cence an each elytron forming an obsolete, broken, transverse fascia
