454 COLYDIIDZ. 
Zunil, Zapote, Capetillo, Senahu, Chiacam (Champion); Panama, Volcan de Chiriqui 
2500 to 6000 feet (Champion). 
Antenne with joints 3-10 small; the club moderately large, quite undivided. Thorax 
short, deeply emarginate in front on each side, so that the front angles are prominent ;. 
each side is armed with four or five denticles, each bearing a seta directed outwards ; 
the surface is rough, and, like the head, is studded with short, thick, erect sete. The 
elytra are rather short and broad, broader behind than at the shoulders; they are 
variegate with yellow and black in a variable manner, are finely crenate-striate, and are 
studded with short erect sete. Under surface black, with but little sculpture ; meso- 
sternum across tbe middle with three cell-like spaces. 
A small series of this species has been obtained; there is a good deal of difference in 
colour amongst the specimens. 
DITAPHRUS, gen. nov. 
Corpus ovatum, subtus planum, supra transversim convexum. Antenne breves, undecim-articulate; clava 
magna, biarticulata, sutura fere rigida. Sulci antennarii imperfecti, obliqui. Pedes breves, debiles. 
Epistome strongly rounded. yes large. Antenne with the basal joint concealed ; 
the club very large, divided into subequal parts, which are very closely connected. 
Head beneath with oblique, imperfect, antennary grooves, somewhat as in Cicones. 
All the coxee approximate; anterior acetabula slightly open. Legs very feeble; tibiz 
slender, not hispid, not at all thickened towards the base; tarsi small, four-jointed, but. 
the division between the first and second joints indistinct. 
The two-jointed club of the antenne, with imperfect division between the two sub- 
equal joints, is an interesting character of this genus. 
In Pascoe’s collection, now in the British Museum, there is an insect labelled Bitoma 
saginata, Pascoe. This is a species of Ditaphrus, but I cannot find that it has been 
described.
