Pedes tenues ; femora liaud clavata, mutica ; tibiae graciles, breviusculte ; 

 tarsi mediocres, articvdo basali subelongato. 



Type Ceocephalus furcillatus, Schon. Gen, et Spec. Curcul. i. p. 359 

 {D'mrus forcipatus, Westw.). There is a second species for which T 

 cannot find any sathfactory character that will distinguish the male, 

 but whose female is decidedly different from the female of D. fur- 

 cillatus. As neither of these have been described, I have placed the 

 differential characters side by side, so that the peculiarities of each 

 will be seen at once. I have applied the name of dispar to this 

 species, which is from Borneo. 



Diurus furcillatus ($). 



Head moderately long, eyes 

 two or three times its diameter 

 from the posterior angle ; an- 

 tennae inserted between the 

 middle of the rostriun and its 

 base ; rostrum subelongate, gra- 

 dually tapering to the apex, the 

 part beyond the insertion of the 

 antennae smooth and glossy; 

 elytra at the apex narrowed and 

 abruptly depressed, each temii- 

 nating in a stout, subcylindi'ical 

 process. 



Diurus dispar ( $ ). 

 Head short, eye only (?nce its 

 diameter from the posterior an- 

 gle ; antennae inserted near the 

 apex of the rostrum ; rostrum 

 short, thick at the base, abruptly 

 narrowed beyond the insertion of 

 the antennoe, from thence to the 

 apex rough (comparatively) and 

 opake ; elj^ra scarcely narrowed 

 at, but sloping rapidly to the 

 apex, which is truncate, with a 

 short slender spine at each outer 

 ang'le. 



MiOLISPA. 



Caput subquadratum, basi truncatum, coUo brevi. Rostrum breve, arcua- 

 tum, basi trisulcatum, apice dilatatum ; mandibulis exsertis. Antenna 

 breviusculse, iucrassatae, versus medium rostri insertae ; articidis exte- 

 rioribus transversis, secundo unilatei-ali, basi constricto, tribus ultimis 

 majoribus perfoliatis. Prothorax oblongo-ovatus, anterius angustior, 

 convexus, lae^ds. Elytra subbrevia, subcylindrica, apice mutica. Pedes 

 breviusculi, antice longiores ; femoribus tibiisque muticis ; tai'sis bre- 

 vibus. 



Trachelizus appears to be the nearest ally of this genus, from which 

 it differs principally in the form of the head, in the rostnim, antennfe, 

 and the non-canaliculate prothorax. 



Miolispa suturalis. 



M. fulva, nitida ; elj-tris prope suturam simpliciter striatis, feiTugineis, 



striis exterioribus fortiter punctatis. 

 Hah. Amboyna, Batchian, &c. 



Fulvous yellow generally, but varying in intensity and amoimt ; the 



head, rostrum, antennae, and anterior margin of the prothorax black, or
