confined to this species. It is uniform in its colour, and, after J. 



angustaius, is the largest and proportionally the most attenuated 



of the genus. 



Prodectoe. 



Caput quadratum, coUo brevissimo. Rostrum elongatiun, vix canalicu- 

 latiun, basi dilatatuni. Anteim^ mediocres, subfilifonnes, versus 

 apicem rostri insertse, articulo secundo primo longiore. Prothorax 

 Bubdepressus, canalicidatus, antice angustus, lateribus ampliatus. Elytra 

 lineares, appendiculata. Pedes tenues, femora baud clavata, mutica, 

 tibiae sublineares, tarsi angusti, articulo basali elongato. 

 Nearly allied to Diurus, from which it is well distinguished by the 



dilated apex of the rostrum, the length of the second joint of the 



antennas, and the canaliculate prothorax. 



Prodecior laminatus. 



P. niger, opacus, sparse albo birtus ; elytris seriatim punctatis, lineis 

 duabus albis ornatis, apice productis, appendiculo longo laminate ob- 

 tuso. 



Hab, Menado. 



Elongate, black, opake, with scattered, white, short, scaly hairs ; head 

 narrowly quadrate, rostrum about five times its length, very slender, 

 obsoletely canaliculate, the apex dilated, shining, and coarsely punc- 

 tured ; eyes small, black ; antennae not so long as the rostrum, nearly 

 filiform, inserted near the apex, the second joint longer than the first ; 

 prothorax less than half the lengih of the el}i;ra, depressed, naiTow in 

 front, enlarged at the sides, broadly canaliculate above ; elytra parallel, 

 reo-ularly seriate-punctate, a line of white hairs on each, near the suture 

 the apex produced into a long, lanceolate, obtuse lamina ; legs slender, 

 of moderate length, tibiae nearly straight, shortly spined at the apex, 

 tarsi narrow, the basal joint elongate. Length 21 lines. 



Varies in the length of the caudal appendage (which, in the 

 specimen from which the above description was made, was nearly as 

 long as the elytra), as well as in size and relative proportions. 



Diurus of Dejean still remains, I believe, a mere catalogue name, 

 although it has been many years proposed, and is well known as 

 designating one of the most extraordinary of this extraordinary 

 family ; the following are the principal characters of the genus : — 



DiXJETIS. 



Caput tenuissimum, vix rostro crassius. Bostrtim elongatum, subcylin- 

 dricum, apice baud dilatato. Antenncs mediocres, subfiliformes, articulo 

 secundo parvo, versus apicem rostri insertse. Prothorax supra convexus, 

 antice angustior, baud canalicidatus. Elytra linearia, appendiculata.
