670 Longicornia Malayana. 



emarginatus ; manclibuloe attenuatse, acutae, intus 



inermes. Oculi integri^ supra sat distantes. Palpi in- 



sequales, robusti. Antennoe dimidio corporis eequales ; 



scapo modice elongato, compresso, arcuato^ ad apicem 



crassiore ; articulo tertio fere scapo sequali ; cseteris 



ad decimum multo brevioribus et sequalibus ; ultimo 



paulo longiore, subfusiformi. Prothorax parvus, 



transversus, convexus, supra inaequalis, antice ro- 



tundatus, lateribus in spinam productis. Elytra valde 



elongata, parallela, spina suturali instructa. Pedes 



mediocres, inermes ; tarsi postici articulo basali baud 



elongate. Prosternum leviter productum, in medio 



canaliculatum. Mesosternum declive, angustum. 



Corpus glabrum. 



Unfortunately the male is unknown, and the position 



of the genus is therefore uncertain. It is remarkable for 



its very small head and prothorax compared to the elytra, 



and it is with reason that M. Lacordaire says, that its 



appearance authorizes us to believe that the male will 



prove this to be a very distinct genus.

Fulvous-brown, shining; head with small irregular 

 punctures, clypeus very concave, forming nearly the 

 whole space between the antennary tubers, mandibles 

 straight on the outer edge, sinuate internally at the base ; 

 prothorax very irregular above, roughly although not 

 largeily punctured, the middle with two considerable ele- 

 vations, with a smaller one on each side, and at the base 

 two others of intermediate size and smoother, the lateral 

 spine depressed above, commencing behind the middle, 

 anterior to which the side is slightly crenulate ; scutellum 

 oblong, rounded behind; elytra eight times as long as 

 the prothorax, and nearly twice as broad (exclusive of 

 the spines) , finely punctured, the punctures more or less 

 confluent, the intervals forming little intricate rugosities ; 

 body beneath pale fulvous-ferruginous, glabrous, except 

 a slight pubescence on the sterna ; legs and antennae of 

 the same colour, all glabrous and glossy. 



Length 20 lines.
