When writing his revision, the author (Matthews, 1966) believed 
that Canthochilum either did not exist on Hispaniola, or was “re- 
duced to as-yet-undiscovered pockets”, since he did not get it during 
his five-day visit there. In this he proved to be wrong on all counts. 
Not only does it occur there, but there are at least three species, 
one of which is fairly widespread. Furthermore, the “pockets” were 
not undiscovered, but had been sampled by Dr. P. J. Darlington in 
1934 and 1938 (this material was not previously available to the 
author) . 
Two of the species are described below. The third cannot be named 
at present as it is represented by only half a specimen, and while 
this actually presents enough characters for diagnosis, it is not desira- 
ble to establish a fragment as a holotype. The following descriptions 
are diagnostic and do not repeat generic characteristics or those not 
previously found to be useful in separating species. 
Canthochilum darlingtoni, new species. 
Description. -Oval, feebly convex, piceous to fuscous (one teneral 
specimen yellow), shiny, antennae and legs fuscous. Head.- Clypeal 
margin with four small teeth and an angulation at clypeo-genal 
suture. Dorsal ocular areas large, separated by a distance equal to 
3 times their width (fig. 1 ). Head surface entirely smooth, uniformly 
very finely and sparsely punctate. Thorax.- Pronotum entirely 
smooth, shiny, uniformly very finely and sparsely punctate. Elytra 
moderately convex, intervals absolutely flat and extremely finely 
punctate, shiny. Striae indistinct, not at all impressed, very finely 
punctate except for 8th stria, which is coarsely punctate. Lateral 
Carina alongside 7th stria extending for about y of elytral length, 
not continued as a ridge posteriorly. Fully winged. Underside im- 
punctate, faintly shagreened. Meso-metasternal suture obtusely an- 
gulate in the middle. Inner mid-coxal margin on median lobe of 
metasternum narrow, curving inward anteriorly to meet meso- 
metasternal suture at a very obtuse angle. Outer mid-coxal margin 
uniformly narrow, paralleling edge of coxal cavity. Fore tibiae with 
distal edge straight, perpendicular to inner edge (fig. 2). Abdomen.- 
Sternites of approximately equal length along mid-line. Pygidium 
entirely margined, the disc convex, smooth and very finely punctate. 
Aedeagus with parameres triangular, basal piece with flattened ventral 
extension (fig. 4) . Total length.- 3.0 — 4.2 mm. 
Sexual dimorphism.- Major males have a widened prothorax, which 
thus has its lateral margins almost parallel ; minor males and females 
have the lateral edges converging anteriorly. All males have a some-
