DOLICHOPROSOPUS. 149 



pubescence), provided with an impressed median line, ex- 

 tending from the anterior margin of the clypeus up to 

 the prothorax. The scape of the antennae sculptured in 

 a similar manner as the head. 



The prothorax with one anterior and two posterior dis- 

 tinct transverse grooves , the anterior one bent backwards 

 in the middle, the posterior ones straight. The naked la- 

 teral spines obliquely directed upwards. The scutellum 

 triangular , rounded at the apex. 



The elytra with a few granules at the base and shoul- 

 ders , followed up by deeply impressed punctures , which 

 however become less and less marked towards the apex. 



Legs and antennae delicately sculptured. 



Captured at Toelabollo (North Celebes) by Baron von 

 Rosenberg , whose name was attached to the species by the 

 late Dr. Snellen van Vollenhoven. 



Doliclioprosopus , g. n. 



Allied to Nemophas and lothocera of which it has the 

 general appearance. It differs however from the first by 

 the declivous mesosteruum (which is neither produced nor 

 tuberculated), by the shape of the lower lobes of the eyes 

 (which are considerably more elongated) and by that of the 

 face (which is much higher than broad between the eyes). 

 Moreover the scape of the antennae is of a more regular 

 sub-conical shape , not angularly incrassate at the tip , and 

 the transverse grooves on the prothorax are less distinct. 



From lothocero , with which it has the declivous meso- 

 sternum in common, it differs by the more elongate lower 

 lobes of the eyes and face , by the straight thoracical spines , 

 by the pubescent , not granulated shoulders , by the broadly 

 rounded apices of the elytra, etc. 



4. Dolichoprosopus macidatus , sp. n. 9- 



Length 40 mm., breadth at the shoulders 12 mm. — 

 Black , covered all over with a short and extremely dense 

 pubescence, which is of a mouse-grey color on the head,
