134 RHYNCHOPHORA. 
Group 3. 
9. Epagrius constans, sp. n. (Tab. V. fig. 22, 3 .) 
Nigerrimus, subopacus, nudus ; prothorace dorso leviter impresso, punctis impressis paucis irregulariter sitis ; 
elytris punctis magnis, profundis, seriatim dispositis, ornatis. 
Long. 10-12 millim. 
Hab. Guatemata, Totonicapam 8500 to 10,500 feet (Champion). 
Rostrum much broader towards the extremity, nearly flat, finely punctate, alutaceous, 
dull, the lateral impressions wanting, the frontal fovea minute but distinct. Thorax 
very coarsely punctate at the sides, the disc slightly depressed, the depression separated 
from each side by a broad slight elevation which is free from punctuation; in the 
depression there are twelve or fifteen punctures irregularly arranged ; basal margin 
very distinct. Elytra with rows of very sharply defined, deep, rather large punctures ; 
the surface between the punctures is almost destitute of sculpture, and there is not 
the slightest elevation of any of the interstices. 
Mr. Champion obtained a series of about 100 examples of this species, from beneath 
stones on an exposed portion of the Central Cordillera of Guatemala. The males are 
more slender than the specimens of the other sex, and they have the base of the elytra 
more deeply emarginate, so that the shoulders project rather more in front. Except 
in these sexual distinctions the series exhibits very little variation. 
10. Epagrius simplex, sp. n. 
Niger, subopacus, nudus; prothorace punctulato, dorso deplanato, lateribus utrinque subimpressis ; elytris 
seriatim sat fortiter punctatis. 
Long. 10 millim. 
Hab. GuateMata, Quezaltenango 7800 feet (Champion). 
Rostrum moderately finely and closely punctate, feebly impressed on the middle of 
the anterior part, with a fovea between the eyes, the latter a little prominent. Thorax 
elongate, rounded at the sides, the disc somewhat deplanate, and with two vague 
irregular, oblique depressions one in front of the other; the surface is rather closely 
punctulate and at the sides is rugose; the flanks are deplanate. Elytra with regular 
series of moderately large remote punctures, the interstices not at all elevated, finely 
punctate. One specimen. 
This species differs from E. constans in the sculpture, and in the absence of the 
large punctures on the disc of the thorax. From E. opacus and its allies it differs in 
the details of sculpture, and in the fact that the disc of the thorax is only imperfectly 
flattened and impressed.
