658 . DERMESTIDA, 
13. Cryptorhopalum guatemalenum, sp. n. 
Breviter ovale, nigrum, griseo-pubescens, elytrorum margine ad apicem vage rufescente; crebrius, fortiter 
punctatum, haud nitidum; pedibus rufis, femoribus nigricantibus; antennis medio testaceo, clava 
elongata, apicem versus fuscescente. 
Long. 3 millim. 
Hab. GUATEMALA, near the city, Zapote, Capetillo (Champion). 
The pubescence in this insect covers the surface more evenly, and on this account 
and its paler colour is more conspicuous than usual. The thorax is distinctly punc- 
tured, even on the disc; the punctuation of the elytra is rather coarse and rough. 
On the under surface the metasternum is coarsely punctate, the punctuation and 
pubescence dense. The club of the antenna is long and broad; the terminal joint is 
always dark, and is not so short as in the allied species: in the male it is two-thirds 
or three-fifths the length of the preceding joint; in the female it is not much shorter 
than the preceding joint. Twenty specimens. One of them, from Guatemala city, has 
the thorax less punctate, and the legs, including the femora, brighter red. 
14, Cryptorhopalum teapense, sp. n. 
Breviter ovale, nigrum, elytris piceo-rufis, flavo-pubescens, antennis pedibusque rufis; elytris crebrius sat 
fortiter punctatis ; antennarum clava parum elongata. 
Long. 22 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Extremely similar to the specimens of C. affine with red elytra, but readily distin- 
guished therefrom by the smaller club of the antenna. In the male the terminal joint 
is unusually small, is narrower than the preceding joint, and only about one-third as 
long. In the females the antennal distinctions of the two species are much less marked. 
There is a fine punctuation on the disc of the thorax. The punctuation of the under 
surface is very dense. ‘The legs, including the femora, are red. Five specimens. 
15. Cryptorhopalum appendiculatum, sp.n. (T'ab. XIX. fig. 22, g antenna.) 
Breviter ovale, nigrum, nitidum, subtiliter fusco-pubescens, antennis pedibusque fuscis; elytris fortiter sat 
crebre punctatis ; antennarum clava elongata, articulo ultimo minuto. 
Long. 22 millim. 
Hab. Mexico, Rincon in Guerrero (1. H. Smith). 
Distinguished from C. teapense by the black colour, and by the very elongate club of 
the male antenna, which, however, is chiefly formed by one joint, the terminal joint 
being minute. The thorax, though quite shining, is definitely punctate. ‘The punc- 
tuation of the elytra is also definite, and is not dense and confluent on the basal part. 
The terminal joint of the antenna in the male is only about one-fourth as long as the 
preceding joint. The femora are nearly black. One specimen.
