408 Mr. D. Sharp's Contrihntions to the 



AnteniKU \\ liii. in length, nitlier stont, pitchy bhick, 

 Avith the basal joints rather paler; of joints 4 — 10 each is 

 a little longer than its predecessor. Head with two curved 

 lines on the front part, which meet so as to form an acute 

 angle on the middle of the head ; antenna! callosities stout, 

 but not greatly elevated ; the whole surface densely rugose, 

 quite opaque. Thorax strongly transverse; the sides 

 rounded and distinctly narrowed in front, behind the 

 middle with a short stout tooth, and behind this tooth cut 

 away, the hind angles being distinctly marked and just 

 rectangular; the whole surface is densely and coarsely 

 rugose, quite dull ; there is no distinct impression along 

 the middle, and in front of the hind angles is a scarcely 

 definite longitudinal impression, i^eaching nearly to the 

 front margin. Elytra longer than the thorax, their 

 sculpture on each consisting of a sutural, and six other 

 fine, elevated, longitudinal lines ; the broad spaces between 

 these lines are peculiarly opaque, and are marked with 

 some indistinct transverse marks, wdiicli probably represent 

 obsolete coarse punctures. Plind body quite dull, densely 

 and rather finely punctured ; the apical segments and the 

 hind margin of the 6th segment reddish ; under surface 

 not so didl as the upper ; metasternum covered with 

 coarse punctures and with a fovea at the extremity in the 

 middle. Legs dull red. 



Ega ; a single individual, whose sex is unknown.

 capitc mutico, longitudlnaliter striguloso ; prothorace 

 lateribus trisinuatis, dense fortiterque punctato ; elytris 

 lineis 6 elevatis; interstitiis transversim rugosis ; abdominc 

 dense fortiterque punctato, apice dilutiore. Long. corp.

Antennse 1-^ lin. in length, stout, pitchy, the basal joints 

 obscure red; 8rd joint scarcely so long as 2nd, 4th a good 

 deal stouter than and cpiite as long as 3rd, 5 — 10 differing 

 little from one another in length, each slightly stouter 

 than its predecessor, 11th a little longer than but scarcely 

 so broad as lOtli. Head without im]irossions or lines, the 

 antcnnal callosities only being present; tlie surface densely 

 covered with longitudinal ruga}. Thorax broader than 

 long, the front margin a little sinuate on each side the 

 middle, so that the li-ont angles are somewhat ]>rominent ; 

 the sides each with two notches, so that they exhibit three
