178 THE BRENTHID^E P'ROM JAVA. 



fortiter punctato-sulcatis , interstitiis convexis^ elevatis , lineis 

 punctis ferrugineis ornatis. 



Long. 15 mm.; lat. protlior. 2^/3 mm. 



Of the same group as 0. lineolatus Kirsch and Bitsemce 

 Senna and allied to 0. insignis Lewis but certainly distinct. 

 The head is short and small comparably to the size of this 

 species , the base is subtruncate and deeply separate from 

 the neck , the hinder angles a little prominent but not 

 spined , above with an obsolete channel in the middle and 

 a few punctures. The basal portion of the rostrum is 

 longer than the head and stoutish , deeply furrowed above 

 and almost bilobed to the insertion of the antennae; the 

 apical part IVg as long as the base, cylindrical, the ex- 

 treme margin is almost of the same broadness as the 

 rest; smooth above, scattered with very minute tubercles 

 and v^ith a row of teeth at the sides : beneath the rostrum 

 is depressed at the apex and scarcely keeled between the 

 antennae. These are as long the thorax , the head and the 

 basal portion of the rostrum together; the 1st joint is clavate, 

 equal in length to the 2nd and 3rd united ; the 2nd curved 

 externally at the base, the 3rd and 4th a little narrower at 

 the base , the remainder almost cylindrical and equal in 

 length, the apical obtusely pointed at the tip and as long 

 as the two preceding ones : the joints are moderately per- 

 foliate and hairy. 



Prothorax ovate, curved at the sides, narrower anteriorly 

 than at the base , where it is termined by a large collar 

 transversely furrowed ; convex above , very shining , with- 

 out any furrow or punctures , but with a median notch 

 at the base. 



Elytra almost as long as twice the prothorax , with the 

 base subtruncate, the shoulders slightly callous, the sides 

 hardly broader than the base, the apex emarginate and 

 a little explanate , the outer angles rounded ; deeply punc- 

 tato-sulcate above, the 1st furrow near the suture obsolete 

 punctate, the interstices convex, raised, slightly curved 

 at the base. The 2nd interstice from the suture has four
