STROl'HICUS. — KKCAirCBUS. 73 



Antennas dusky, linear. Thorax pale yellow, subquadrate (the 

 anterior margin arcuate) ; the anterior and lateral margins closely 

 and rather roughly punctured ; the mesial areolet very shallow, ex- 

 tending nearly to the front margin. tScutellum fuscous. Elytra 

 parallel, fuscous, rather paler towards the base ; the second and 

 fourth costas complete, the first and third not extending beyond the 

 middle of the elytra, the intervals with four lines of close, small 

 punctures. 



STROPHICUS. 



Antennas linear. Thorax with a single lanceolate mesial areolet. 

 Elytra parallel ; each elytron with four distinct costas, the third ab- 

 breviated posteriorly ; the interstices with punctures, which are 

 divided from each other by transverse carinas; these punctures are, 

 here and there, in double lines, but they are generally transverse and 

 extend across the whole interstice. 



It is somewhat doubtful whether this genus should be placed 

 after Xylobanns or Trichalus ; the linear antenna? and general form, 

 however, make the latver position appear preferable. 



Strophicus nigellus. 



(Plate XVII. fig. 11.) 



Fuscus, subopacus ; thorace trapezoidali, lateribus haud reflexis ; 

 singulo elytro quadricostato, costa tertia postice obliterate, inter- 

 stitiis sat fortiter punctatis. $ . Long. 2| lin. 



Hub. My sol (Wallace). 



Thorax with the mesial areolet very distinct and elevated. Elytra 

 parallel, the third costa much obliterated behind the middle ; the 

 first and second intervals have two lines of rather strong, clear (but 

 unequal sized) punctures ; beyond the middle these punctures fre- 

 quently coalesce laterally, so that posteriorly there appears to be 

 only a single row of transverse punctures ; the third and fourth in- 

 tervals have two lines of punctures. 



METAN(EUS. 



Eyes large. Antennas long, with the third to tenth joints in the 

 male each with a long compressed branch arising from the base. 

 Thorax pubescent, with seven shallow impressions. Elytra pubes- 

 cent, with four parallel costae; the interstices each with a line of 

 obscure punctures on each side. 



Three species of this genus arc at present known.
