JAVANESE BRENTHIDAE. 61 



the median joints cylindrical, and gradually increasing in 

 length, the apical ones almost as long as the two prece- 

 ding joints together, pointed at the tip. 



Prothorax ovate, narrower anteriorly than behind , with a 

 broad margin at the base, transversely furrowed, convex above, 

 scattered with very fine punctures which bear short hairs. 



Elytra twice as long as the prothorax and broader than 

 it, the shoulders are rounded, the sides almost parallel 

 in the middle, gradually curved and narrower behind the 

 middle, the tip is almost truncate with the external angles 

 obtusely toothed; above the elytra are strongly punctured 

 and furrowed; some punctures at the sides are hair-bearing 

 but the hairs are shorter than in Ps. piliferus (Senna) ; 

 the 1st furrow is impunctate, the l^t interstice (sutural) is 

 depressed and regular, the 2'^'^ depressed but of irregular 

 width, the following interstices are more raised and convex, 

 broader where they have the yellow-ferruginous lines. The 

 disposition of these lines is the following : the S^d interstice 

 bears two lines in the apical third, the 4*^ has a line 

 near the base, another near the middle and a spot behind 

 it, the 5th has a short line at the base and another be- 

 hind the middle, the 7th a line behind the middle, the 

 Sth a short line at the same position and another longer 

 one on the basal third , where a short line is visible on 

 the 9'h interstice which has also a longer one near the tip. 



Thighs clubshaped and spiued in the apical third. Body 

 beneath shining, head and metarostrum with a line of punctures 

 beariug hairs and the median interspace raised ; metasternum 

 foveolate at the apex , the base of the abdomen is convex. 



Of this handsome species, Mr. Pasteur sent me a single 

 female. The male has certainly a slender rostrum, the eyes 

 more prominent, the prothorax more attenuate near the 

 apex and broader behind the middle. Ps. dentipennis is 

 easily distinguishable from all the species which have likewise 

 a slender rostrum, by the obtusely toothed external apical 

 angles of the elytra and by the 2^'! interstice being depressed 

 in the median portion.
