New Species of Phytophagous Insects. 147 



Oblong-elongate, convex above, shining rufo-fulvous ; antennae, 

 a villa on the thorax, the scutellum and tlie elytra black; knees, 

 tibiae and tarsi piceous. Head constricted behind the eyes ; front 

 with an oblique groove on either side; face transversely grooved 

 just above the insertion of the antennaa; the latter slender, filiform, 

 nearly equal in length to the body, their third joint obovate, 

 nearly twice the length of the second. Thorax sub-quadrate ; 

 sides deeply constricted just behind their middle; above sub- 

 cylindrical, deeply impressed in front of the base by a transverse 

 groove, either end of which terminates in the lateral constriction ; 

 surface smooth and shining, impunctate, bright rufo-fulvous, a 

 broad vitta down the centre, which gradually increases in width 

 behind, and is abbreviated at the transverse groove, black. 

 Scutellum shining black, its apex truncate. Elytra much broader 

 than the thorax, oblong, convex, indistinctly depressed trans- 

 versely below the base ; shining black, whole surface irregularly 

 covered with large deep variolose punctures, more crowded and 

 confluent towards the sides ; interspaces smooth and shining, 

 much thickened and elevated, and forming towards the sides 

 irregular reticulations. Beneath shining rufo-fulvous, abdomen 

 covered with very short adpressed fulvous pubescence ; the apex 

 of jaws, the knees, tibiae (their inner surface excepted) and tarsi 

 pitchy black. 



Hab. Sarawak, Borneo, collected by Mr. Wallace. 



Lema Erycina. 



Oblongo-elongata, nitido-rufo-fulva, pedibus elytrisque nigris, 

 his apice rufo-fulvis ; antennis extrorsum pallide fuscis. 



Long. 4 — 4^ lin. 



Oblong-elongale, shining rufo-fulvous; legs and elytra shining 

 black ; the apex of these latter rufo-fulvous. Head smooth, 

 deeply constricted on either side behind the eyes, front impressed 

 with a deep fovea ; antennae moderately robust, filiform, scarcely 

 longer than half the body. Thorax as broad as long, sub-cylin- 

 drical, sides deeply constricted at their middle; above smooth and 

 shining, impressed behind the middle with a shallow transverse 

 groove, in the centre of which is a single fovea ; a broad longi- 

 tudinal line down the centre of the disc and a space on either side 

 in front finely and sub-remotely punctured. Elytra oblong, 

 transversely depressed below their base, the scutellary space 

 slightly elevated; surface shining black, the apex rufo-fulvous; 

 each elytron with ten rows of fine but distinct punctures; striae
