130 Longicornia Malay ana. 



scapo elongate, cylindrico ; artieulo tertio longiore ; caeteris 

 decrescentibus, Mand'ibulce paulo elongatae. Prothorax sub- 

 oblongus, capite vix latior, lateribus rotundatus. Elytra ob- 

 longa, cylindrica, paulo angusta. Pedes inaequales, antici 

 longiores ; tibice anticae rectae, intermediae extus cristatae ; 

 tarsi antici elongati, articulis duobus primis late tringulari- 

 bus, intermedii et postici breves. Mesosternum dentatura, 

 haod dilatatum. 

 A beautiful insect, having a singular resemblance to Agclasta 

 calUzona in its coloration, is the sole representative of this genus. 

 From Agelasta, however, it is abundantly distinct, not only in 

 the form of the prothorax and mesosternum, but also in the 

 straightness of the protibiaej* and the elongated, parallel, and di- 

 lated anterior tarsi, while on the prothorax little glossy black 

 granulations take the place of punctures. 



Syrrhopcus agelastoides. (PI. VII. fig. 3.) 

 S. tenuiter pubescens, dense fusco-irroratus ; prothorace gra- 



nuloso; elytris fascia lata mediana apiceque rubescentibus. 

 Hah. — Sarawak. 



Covered with a short dense pubescence of a reddish colour, 

 very closely spotted with brown on the upper surface, except the 

 bands on the elytra, but less so on the anterior femora and base 

 of the antennae; head nearly as broad as the prothorax, the latter 

 scarcely longer than broad, the sides regularly rounded, the disc 

 with black glossy granules ; scutellum somewhat quadrate ; elytra 

 punctured, chiefly at the base, with a few scattered granules, the 

 median band rather broad and of a clear pale brick-red colour, 

 the apex also of the same colour ; body beneath dark brown, with 

 a very sparse greyish pubescence ; legs mostly reddish, the anterior 

 femora spotted with brown, the distal extremities of the tibiae, 

 the basal joints of the intermediate and posterior, and the two 

 basal joints of the anterior, tarsi, the tips of the claw-joints and 

 the claws, black; antennae reddish, the tips of the third and most 

 of the following joints black. 



Length 7 lines. 



SORBIA. 



Caput antice transversum, infra oculos paulo dilatatum, fronte 

 convexa, tuberibus antenniferis brevibus. Oculi mediocres, 

 fere divisi. Antennce corpore longiores, basi valde distantes ;
