sternum, which is very short and has a short, broad, prosternal process. The middle 
coxee are widely separated, and the metasternum is defined in front in the middle by 
a remarkably distinct raised margin, forming a gentle arch: reposing against this the 
inesosternum appears as a small transverse piece on each side. ‘The ventral segments 
are smaller than usual. ‘The coxal plates are highly developed. 
This genus is established for C. rotundus. The second species I have placed in 
Caccoleptus will no doubt have to be separated when more is known about it. 
1. Caccoleptus rotundus, sp.n. (Tab. XIX. fig. 16.) 
Brevis, rotundatus, convexus, supra nigricans, subtus dilute piceus, antennis pedibusque testaceis ; setis sub- 
depressis sat dense vestitus, elytris vix albido-subfasciatis. 
Long. 23, lat, 27 millim. 
Hab. Panama, Bugaba (Champion). 
We have only one specimen of this species, and I am uncertain as to its sex, but it 
is probably a male. The antenne are short, rather stout, thicker towards the extremity ; 
first and second joints short and stout, third and fourth quite small: from this onwards 
the antenna becomes gradually thicker, the tenth joint being strongly transverse ; the 
terminal joint is short, but nearly twice as long as the tenth. ‘he eyes are round, not 
emarginate. The thorax is very short and broad, and is remarkable on account of the 
great prolongation of the base in the middle, which covers and conceals the scutellum. 
‘There is no distinct punctuation of the upper surface, but there is a well-developed 
clothing of hair, which is mostly black; there are, however, numerous white hairs, 
which in a very rudimentary manner form a median fascia. 
2. Caccoleptus anisotomoides, sp. n. 
Rotundato-ovalis, convexus, rufus, capite thoraceque nigricantibus, nitidus, parce subtilissime punctatus, parce 
setosus, hic inde guttis minutis albidis. 
Long. 23 millim. 
Hab. British Honpuras, Rio Hondo (Blancaneauc). 
Antenne very small, almost gradually thickened from the sixth joint to the tenth. 
Head small. Thorax much lobed at the base in the middle, nearly covering the 
scutellum. ‘There is a scanty setosity scattered over the surface, and a few minute spots 
due to small agglomerations of pure white hairs. Legs slender. 
We have only one specimen of this insect, which might almost be described as 
having the form and hind body of Cryptorhopalum, with the head and prothorax of 
Trogoderma. it departs in several points from C. ro¢undus, the middle coxe being less 
widely separated and the mesosternal margin fine, It is somewhat uncertain how 
many joints there are to the antenna: the two short basal joints are definite, and then 
there are two or three more slender joints, the sixth joint distinct and almost forming 
part of the loosely-articulated 5-jointed club.
