CRYPTORHOPALUM. 665 
C. fraternum, but there is not the least trace of any distortion of the sides of the 
thorax. 
The three examples obtained of this species are probably all females; they closely 
resemble one another, except that the club of the antenna is a little darker in one 
of them. Mr. Champion also found a female at Duefias and a male at Calderas that I 
have for the present referred to C. mardelloide. The form is still more oblong, and the 
elytra more elongate. This is almost all there js to distinguish the female, except 
that the punctuation is slightly more evident. The male example has the antennal 
club very large. 
34. Cryptorhopalum ducale, sp. n. 
Ovale, rufum, elytris lete viridi-cyaneis ; tenuiter pubescens, nitidum, subtilius punctatum. 
Long. 4} millim. 
Hab. Guaremata, Las Mercedes 3000 feet (Champion). 
This species cannot be confounded with any other on account of the bright metallic 
colour of the upper surface and the much-diminished pubescence. The antenne are 
red, with an elongate club, the first joint of which is nearly three times as long as 
the last. The pubescence of the upper surface is fine, rather scanty and depressed, 
and the punctuation is very fine and more distant than usual. The under surface and 
legs are red, the pubescence on the ventral segments rather more conspicuous than 
elsewhere. One specimen, probably a male. 
35. Cryptorhopalum equisoles, sp. n. (Tab. XIX. figg. 23; 23 a, breast.) 
Ovale, sat convexum, nigerrimum, glabrum, thorace elytrisque punctis rudis nonnullis impressis. 
Long. 2-23 millim. 
Hab, Mexico, Rincon in Guerrero (1. H. Smith); Brrvisa Hoypvras, Belize 
(Blancaneauxr). 
This insect, though very peculiar in appearance, has apparently but little to distin- 
guish it from a normal Cryptorhopalum, though the ocellus is extremely indistinct ; its 
intense black colour (only the minute intermediate joints of the antenne being 
yellowish), the quite glabrous surface, and the peculiar, large, but imperfect, 
punctures on the upper surface are diagnostic. On the under surface it presents a 
very remarkable feature, the whole of the middle of the metasternum being highly 
polished and quite smooth, and this space limited by a horseshoe-shaped raised line ; 
the prosternum is rugose, the sides of the metasternum are coarsely punctured, the 
ventral segments finely punctured. The middle femora are laminate and definitely 
punctured. ‘The tarsi are black. The club of the antenna is oval, its two joints 
closely co-adapted, the terminal joint not quite so large as the preceding one. Five 
specimens.
