the dorsum. The claws are very strongly toothed at the base. Four specimens, very 

 similar to one another, and probably all males. The species appears to be nearer G. 

 aluensis than any other. 



Glenea venus Thomson. One specimen. 



Family BRENTHIDAE. 

 Cacoschizus, n. g. (Ceocephalides). 



Tarsi quinque-articulati ; articulis 1° et 2° transversis, 3° quadrato, supeme latissime 

 fere ad basin impresso, margine apicali sat profunde emarginato, 4° 5°que crassis, 4° 

 paulo ultra apicem tertii extenso, ab quinto bene discreto, hoc ceteris conjunctis 

 longitudine fere aequali. 



I establish this genus for a Brenthid with very peculiar feet. The species I 

 believe is Schizotrachelus schmeltzii Fairm. Lacordaire in describing the genus Schizo- 

 trachelus (Genera Col. vii. p. 455) describes the tarsi as follows: " tarses spongieux 

 en dessous, a articles 1 — 3 courts, egaux, 3 entier." In the structure of the feet 

 Cacoschizus comes nearest to certain species of the genus Trachelizus, but from that 

 genus it is readily distinguished b}' the head being separated from the neck by a verv 

 deep constriction.

Fairmaii-e described the male onlj', we figure the two sexes; in the structure of the 

 feet the female agrees with the male. The peculiar tarsi are of considerable interest, as 

 distinctly 5-jointed tarsi are of very rare occurrence in the Rhynchophorous series of 

 Coleoptera. The resemblance of both the sexes of Cacoschizus to Trachelizus is very 

 great, and though Schizotrachelus and Trachelizus are widely separated in Lacordaire's 

 classification, I think they are nevertheless naturally allied. 



Cacotrachelus, n. g. (Eutrachelides). 



Mas. Caput elongatum, convexum ; rostrum breve, apice latiore, mandibulis brevibus 

 spatio parvo includentibus. Antennae breves, crassae. Prothorax convexus, subovalis, 

 anterius utrinque obsolete convexo, dorso posterius subtiliter canaliculato. Pedes breves 

 crassiusculae, femoribus brevibus, basi hand pedicellato ; tibiis brevibus compressis, apice 

 interne mucronato ; tarsis crassis, subtus spongiosis, articulato tertio breviter bdobato. 



Lacordaire's gi-oup Eutrachelides consists of a single species of gigautic Brenthidae — 

 Eutrachelus temmirickii — from Java. The genus I am at present establishing is totally 

 different from Eutrachelus in appearance, but is I think really allied to it. I have long 

 had in mj- collection a Brenthid from Java that is closely allied to the insect brought
