10° quam 9" sat breviori, apicali quam precedentes 2 con-

Var.? dilutior. Pallide brunneo-testaceus, elytris apicem versus 
picescentibus. Long., 1%, 1.; lat., 1 1, 
Resembles P. obtusus, Blackb., in shape, but differs from it 
and from the other previously described species inter alia by the 
very deeply impressed lateral striz of its elytra.

P. comis, sp. nov. Subrotundus, postice sat acuminatus; nitidus ; 
brunneo-testaceus, hic illic indeterminate obscurior ; capite 
prothoraceque subtilissime sat sparsim punctulatis ; elytris 
distincte subtiliter striatis, striis suturam versus subtiliter 
latera versus multo minus subtiliter punctulatis, interstitiis 
distincte minus crebre punctulatis; antennarum articulo 
basali sat dilatato, apicali quam precedentes 2 conjuncti sat 
breviori. Long., 1,', 1. (vix); lat., =% 1. 
Resembles P. obtusus, Blackb., in shape and elytral striation 
but differs in the very well defined puncturation of its elytral 
strie. P. rotundus, Blackb., has punctulate strie but its strize 
(especially the lateral ones) are very much more finely punctured 
and its shape is very different, being shorter and evidently more 
nearly circular.

C. Gilesi, sp. nov. (Mas.)  Elongatus, sat parallelus ; crasse 
rugulose (in prothorace inzqualiter) punctulatis; niger, 
squamis adpressis aurantiacis sparsim vestitus ; capite supra 
tuberculo mediano (hoc ad apicem vix bifido) instructo ; 
mandibulis quam caput vix longioribus, in medio obtuse 
leviter auriculatis, ad apicem trifidis (lobo intermedio quam 
ceteri longiori); prothorace quam longiori fere dimidia parte 
latiori, antice sat angustato, longitudinaliter profunde sul- 
cato; elytris irregulariter costatis, costis alternis quam 
ceterze majoribus. 
Femine mandibulis brevibus nec auriculatis. Long. (mands. 
incl.), 6—64 1. 
A very distinct species. Compared with C. niger, Westw., it 
differs by the form of the mandibles which are trifid at the apex 
(the three lobes all pointing in a direction continuing the length 
of the mandible) and in the male have a small obtuse elevation 
about the middle of their length (this elevation is much smaller 
and further from the base than the elevation on the mandibles of 
C. Frogatti, Blackb.); also differs from C. niger by its coarser
