CRYPTARCHA. 379 
12. Cryptarcha morata, sp. n. 
Oblonga, parum convexa, supra nigra, prothorace margines versus elytrisque circa scutellum rufis, antennis 
pedibusque testaceis, illarum clava nigra; subtus fusca, prosterno capiteque rufescentibus ; pubescens, 
nitida, parcius subtiliusque punctata. 
Long. 53 millim. 
Hab, GuateMa.a, Duefias (Champion). 
Antenne moderately long; club elongate, laxly articulated, the terminal joint some- 
what small, ferruginous externally. Head rather small, moderately coarsely punctate, 
the sides simply convexly curved. Thorax short, shining, sparingly and finely punctate, 
with a scanty but moderately long pubescence. Scutellum narrow, extremely finely 
punctate. Elytra with fine and distant, subseriate punctuation and with scanty but 
rather long griseous pubescence. Pygidium red, rounded at the extremity, very little 
exposed. 
This is not closely allied to any other species, so I have described it, although we 
have received only one specimen, and the mandibles are broken. I think it belongs to 
the series in which the mandibles are equal and moderately long. 
13. Cryptarcha regularis, sp.n. (Tab. XII. fig. 12.) 
Oblonga, angusta, sat convexa, rufa, capite, prothorace, elytris antennarumque clava nigris, prothoracis elytro- 
rumque basibus rufescentibus ; elytris regulariter seriatim punctatis et pubescentibus, interstitiis nitidis, 
impunctatis. 
Long. 4-43 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Head sparingly punctate, the sides concavely arcuate; mandibles moderately long, a 
little unequal. Thorax elongate, sparingly punctate. lytra with quite regular 
series of fine punctures and pubescence. Pygidium large, closely punctate, very gently 
rounded at the extremity. Under surface red ; head fuscous-red. 
This is not at all close to any other species here described. Four specimens have 
been received ; I am uncertain as to their sex, but it is possible that they are all males. 
The regular series of fine punctures and pubescence, without sculpture or pubescence 
on the shining interstices, distinguish it from all the allied forms; the series are about 
eight in number on each wing-case, and external to them there are some more confused 
series or irregularly arranged punctures. | 
A single example from Panima in Guatemala (Champion) is considerably smaller, 
and I think may belong to a closely allied species. 
14. Cryptarcha plena, sp.n. (Tab. XII. fig. 13.) 
Brevior, fusco-ferruginea, dense punctata, pubescens, fere opaca, antennarum clava fusca; elytris subtiliter 
seriatim punctatis, interstitiis subseriatim punctatis. 
Long. 23-3? millim. 
Hab. Mexico, Cordova, Mirador, Jalapa (Hoge); British Honpuras, R. Hondo
