and numerous punctures continuing to near the apex, and inter- 

 spersed with many irregular points, and the thorax is covered 

 with very minute but distinct points. Underneath, the body is 

 very shining and deep red, with the exceptiou of the metasternum, 

 which is black and which, with the abdomen, is glabrous. 



About ten examples were found. 



Obs. With regard to Tritomiclea, if Motschulsky's drawing of 

 the anteuna be correct, there are but Jive joints to the funicular 

 portion of the antenna preceding the capitulus, and that portion 

 itself is made up of three joints, which is certainly not the case in 

 the West-Indian insect.

A single female specimen of an Anidrytus, belonging to Section B, 

 which are species of a depressed form and with the elvti'a not 

 very ovate and but slightly convex. The Anidryti are very similar 

 in form and colour, and it would be very difficult to determine 

 this example in the absence of the male, but it appears to be most 

 like A. parallelus Gerst. The genus has not, I believe, been 

 recorded previously from the Antilles.

Rhtmbits globosus, sp. n. 



Orbicularis, valde convexus, niger ; corpore suhtus, pedibus inter-

Bab. Grenada : Chantilly Estate, windward side (H. H. Smith). 



Very convex, shining, clothed with pubescence, which is greyish 

 on the thorax and rufous on the elytra. Head, antennae, palpi, 

 and thorax black ; the antennae as long as would reach rather 

 further than the hind angles of the thorax, 10-jointed. Thorax 

 black and shining, the sides narrowly margined and reflexed ; the 

 basal sulci are distinct, wide at their bases, strongly convergent 

 and arcuate, terminating as fine lines. Scutelium brownish. Elytra 

 brown ; the punctation is line but just visible as separate points 

 under the quarter-inch Coddington lens. The legs are red, with 

 the tibiae rather more obscurely pitchy or red, the anterior pair 

 being more obscure than the middle and posterior legs. 



Six specimens of this little Ehymbus were obtained ; it is very 

 distinct from any other described species.
