CRYPTORHOPALUM. 661 
second is evidently, though not greatly, shorter than the first; the total length of 
the club is a little less than s millim. In the female the club is much smaller. 
The lobe of the base of the thorax is broad and abrupt, the sinuation on each side of 
it being very strong. 
I refer six specimens to this species, but there are several others that are either 
varieties or allied forms. 
22. Cryptorhopalum gravidum, sp. n. 
Ovale, convexum, crebre subtiliter punctatum, nigro-pubescens, sat nitidum; pedibus fusco-rufis, femoribus 
nigris; antennis medio flavo, clava nigricante. 
Long. 3-34 millim. 
Hab. Mexico, Chilpancingo, Cuernavaca (Sailé). 
In this species the club of the male antenna is very elongate, but it is broad and 
the terminal joint is quite small, being only one-fourth the length of that preceding it. 
The thorax is quite definitely punctured, even on the disc; the punctuation of the 
elytra is more scanty, but their pubescence is very conspicuous on the apical parts. 
Four specimens. 
23. Cryptorhopalum ventanense, sp. n. 
Ovale, convexum, crebre subtiliter punctatum, fusco-nigro-pubescens; pedibus fusco-rufis, femoribus nigris ; 
antennis medio flavo, clava rufescente. 
Long. 37 millim. 
Hab. Mexico, Ventanas in Durango (fége). 
In this insect the club of the male antenna, besides being paler, is more slender 
than it is in C. gravidum, but the relative proportions of its two joints are about the 
same. ‘The pubescence on the elytra is not quite so black. Three specimens. 
24. Cryptorhopalum funestum, sp. n. 
Oblongo-ovale, sat convexum, nigrum, nigro-pubescens, crebrius punctatum; antennis medio flavo, clava 
nigricante. 
Long. 24 millim. 
Hab. Mexico, Ventanas (forrer), Chilpancingo (HZ. H. Smith). 
Smaller than C. gravidum, and more closely punctured, being also narrower and 
more oblong in form and with the thoracic lobe much narrower. The club of the 
male antenna is elongate, the terminal joint being small, about one-third the length of 
the first joint. The species is further distinguished by possessing a small, indistinct, 
round impression on the centre of the metasternum. The colour of the pubescence 
varies a little, and seems somewhat less black on the underside than it is above. This 
species, at first sight, much resembles C. subtile, which, however, has longer and 
thinner legs and very differently formed antennz. Three specimens.
