'182 THE BRENTHID-E FROM JAVA. 



equal iu length to the preceding ones , with the exception 

 of the basal joint. 



Prothorax elongate, narrower anteriorly and a little 

 broader behind the middle, channeled above and punctu- 

 red, the punctures more numerous towards the base and 

 sometimes scaled. 



Elytra as long as the thorax, head and basal portion of 

 the rostrum taken together, with the base emarginate, the 

 shoulders a little raised , the sides narrower in the middle, 

 the apex truncate and the outer angles terminating iu a 

 slender tail, which is provided at the tip with a few hairs ; 

 above punctato-striate, the apical declivity with a raised 

 interstice: in the female the elytra are only spined at 

 the apex. 



Body beneath iu cf shining, piceous; metasternum con- 

 vex, scattered with scaled punctures, more numerous at the 

 sides: the two basal segments of the abdomen with simi- 

 lar punctures : the 1st with a hairy space in the middle, 

 the 2nd scarcely depressed and scaled at the apical mar- 

 gin , the other segments are scaled and punctured : in the 

 Q the metasternum and the abdomen are convex, shining, 

 and covered with punctures and with a few scales. Legs 

 as in C. longicornis. 



A very polymorphous species: the length of the anten- 

 nae and of the tails is much variable; some specimens have 

 the antennge extending to the apex of the abdomen and 

 the tails longer than Vi of the length of the elytra or 

 as long as these ; in others the antennae and the tails are 

 more or less short and in some males the apex of the 

 elytra is only spined. 



Hab. Western Java. — Several specimens, (ƒ and 9 (Ley- 

 den Museum), obtained from Mr. J. D. Pasteur and a cf

 Lacordaire"; Sumatra (the longest specimens I have seen), 

 collected by Dr. Elio Modigliani (Genoa Museum); Pe- 

 rak, some individuals in my collection ; Sarawak (Borneo),
