 (Diurus forcipatus, Westw.). There is a second species for which I 

 cannot find any satisfactory character that will distinguish the male, 

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

 cUlatus. 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 furcUlatus (§). 

 Head moderately long, eyes 

 two or three times its diameter 

 from the posterior angle ; an- 

 tennae inserted between the 

 middle of the rostrum 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 termi- 

 nating in a stout, subcylindrical 

 process. 



Diurus dispar ( $ ). 

 Head short, eye only once 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 antennae, from thence to the 

 apex rough (comparatively) and 

 opake; elytra scarcely narrowed 

 at, but sloping rapidly to the 

 apex, which is truncate, with a 

 short slender spine at each outer 

 angle. 



Miolispa. 



Caput subquadratum, basi truncatimi, collo brevi. Rostrum breve, arcua- 

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

 breviusculae, incrassatae, versus medium rostri insertae ; articulis exte- 

 rioribus transversis, secundo unilaterali, basi constricto, tribus ultimis 

 majoribus perfoliatis. Prothorax oblongo-ovatus, anterius angustior, 

 convexus, laevis. Elytra subbrevia, subcylindrica, apice mutica. Pedes 

 breviusculi, antice longiores ; femoribus tibiisque muticis ; t arsis 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 rostrum, antennae, 

 and the non- canaliculate prothorax. 



Miolispa suturalis. 



31. fulva, nitida; elytris prope suturam simpliciter striatis, ferrugineis, 



striis exterioribus fortiter punctatis. 

 Hab. Amboyna, Batchian, &c. 



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



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