 broad dark brown band on the vertex, connecting the eyes, 

 and angularly produced forwards in the middle, where it is 

 interrupted by a narrow pale longitudinal line. Front at its 

 narrowest part equal in breadth to one eye. Frontal tubercle 

 moderately large and ratlier deeply bitid. Rostrum ochreous, 

 scarcely as long as the vertical diameter o£ the head; nasus 

 hardly distinguishable. Antennse short, hardly more than 

 half as long as the thorax. First scapal segment ochreous, 

 second a little darkened; flagellum wholly black, the ten 

 distinct segments all approximately cylindrical and equal in 

 length. Palpi black. Thorax practically bare, the integu- 

 ment dull, except the middle and posterior part of the prsd- 

 scutum, which is somewhat shining. Prothorax entirely 

 ochreous. Prsescutum with the ground-colour greyish 

 ochreous in the middle, brownish at the sides, but mostly 

 occupied by four distinct blackish-brown stripes, the outer 

 pair a little more intense and continued across the scutum. 

 Scutellum dull ochreous. Postnotum ochreous, the lateral 

 and posterior margins rather broadly dark brown. Pleura 

 ochreous ; an ill-defined dark stripe along the anterior border

 the posterior border of this part. Abdomen short, deep 

 ochreous, almost orange ; a pair of irregular sublateral 

 blackish stripes extending the whole length ; seventh tergite

 ochreous. Legs almost uniformly brownish, except for the
