1866.] MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. 243 



reddish or fulvous-brown colour, beneath coarser and less compact; 

 head slightly punctured in front, the vertex and between the eyes 

 deeply grooved ; prothorax with an elevated longitudinal line, the 

 base of the spine occupying the middle third on each side ; scutel- 

 lum nearly semicircular ; elytra about five times as long as the pro- 

 thorax, and much broader at the base, minutely and sparingly 

 punctured, the base and a large longitudinal patch on each side 

 behind the middle, where the elytron is hollowed or impressed, dark 

 brown, the apices broadly truncate and expanding beyond the side 

 into a large rectangular convex plate ; legs and antennae concolo- 

 rous. Length 13 lines. 



Dorcadionin^e. 

 Obages. 



Tubera antennifera erecta, approximata. 



Palpi maxillares elongati, art. ultimo dllatato, truncato. 



Prothorax muticus, ovatus, ad elytra arete applicatus. 



Tarsi art. penultimo dilatato. 



Head rather narrow, quadrate in front; the antennary tubers stout, 

 nearly erect, approximate or nearly contiguous at the base. Eyes 

 lateral, broadly emarginate, pointed below. Antennae setaceous, 

 rather longer than the body ; scape subelongate, cylindrical ; third 

 joint longest, the rest gradually shorter. Maxillary palpi very long, 

 the terminal joint, as also in the labial palpi, considerably larger 

 than the preceding ones, and truncate. Prothorax oblong, sub- 

 cylindrical, a little broader than the head, the disk regular, the sides 

 unarmed. Elytra ovate, very convex, the convexity culminating at 

 the middle, not wider than the prothorax at the base, humeral 

 angles entirely absent. Legs rather slender, especially the tibiae of 

 the posterior pair ; femora slightly thickened ; tarsi short, the pe- 

 nultimate joint dilated. Anterior acetabula narrowly angulated. 

 Pro- and mesosterna declivous. 



The unique specimen before me is the only representative of the 

 subfamily in the collection. Mr. Wallace during all his researches 

 only found two species, but neither of these has the slightest affinity 

 to it ; nor can I mention any other to which it can be said to be 

 allied. The Australian genus Microtragus agrees in its eyes and 

 approximate antennary tubers, but differs in other characters, and 

 has a totally different habit. 



Obages palparis. (PI. XXVI. fig. 1 1 .) 



O. piceus, pube sparsa grisea subtiliter indutus. 



Pitchy brown, with a short sparse greyish pile ; head more pubes- 

 cent, rather coarsely punctured ; prothorax covered with coarse 

 crowded punctures ; scutellum very transverse ; elytra deeply striato- 

 punctate, the interstitial lines alone pubescent, the third line from 

 the suture with a small white spot posteriorly, apices obliquely 

 truncate, the outer angle produced ; body beneath, legs, and antennae 

 with a tolerably copious greyish pubescence. Length 4 lines.
