CAMPTODES, 330 
Hab. Guatemata, Zapote (Champion). 
Antenne red, the club rather small. Thorax finely and numerously punctate. Elytra 
scarcely more coarsely punctured than the thorax. Pygidium sparingly and finely 
punctate, but little exposed. Male with the thorax and elytra not so shining as they 
are in the female. 
This is a more polished insect than C. communis, and is distinguished from it by 
important structural characters, the prosternal process being short, the middle coxz less 
widely separated, and the metasternum a little depressed in front in the middle. The 
labrum is more elongate and the mandibles at the apex differently formed. Six examples.

This is apparently a rare species, as we have received only ten specimens. The form 
with immaculate head and thorax considered by Erichson as a variety should be treated 
as the typical form of the species, the insect with maculate head and thorax as a variety. 
C. transversus exhibits much variation in the colour of the posterior parts of the under 
surface, the prosternum and mesosternum being, however, always yellow, but behind 
this the colour varies from yellow to black. There is a great dissimilarity between the 
large and small males, the latter differing but little from the females, while the larger 
examples have the surface quite dull and the sculpture obliterated. C. transversus 
may be distinguished from C. jucundus, to which it is closely allied and with which it 
agrees in the peculiar form of the scutellum, by the rather larger size and more distinct 
punctuation, by the prosternum being not quite so short, and by the different colour: 
though each of the species varies greatly in colour, I have not seen any example of the 
one agreeing with the other in this respect. ‘The elytra of C. transversus are either 
black or black with a green tinge, and the dark colour on the head and thorax when 
present is more definite than it is in the other species. 
22. Camptodes solitarius, sp. n. (Tab. X. fig. 24, 2 .) 
Rotundatus, convexus, dilute rufus, prothorace medio, pectore abdomineque fuscis, elytris nigris, viridi-tinctis, 
sat fortiter punctatis. 
Long. 47 millim. 
Hab. GuateMALa, Duefias (Champion). 
Although we have received only one female of this insect there can be no doubt that 
it belongs to a distinct species. It is allied to C. transversus, but the prosternal process 
is evidently longer and broader than in that species, and the punctuation of the elytra 
is considerably coarser ; these characters also separate it from C. gucundus, to the dark
