the lower in the middle smooth except for some transverse 

 stria?, the centre carinate. The whole thorax is thickly 

 covered with pale pubescence. The second cubital cellule is 

 much narrowed at the top, being there in length less than the 

 distance bounded by the second transverse cubital and the 

 second recurrent nervure. Legs entirely black, thickly 

 covered with pale pubescence. Tegulse rufous. Abdomen 

 black, the basal two segments banded with yellow, the bands 

 interrupted in the middle ; the basal two segments closely 

 punctured, the third and fourth more closely, the apical 

 alutaceous. 



The apex of the clypeus is broader than usual and does not 

 project into teeth ; it is flat, with the sides oblique ; the 

 insect is more densely pilose than usual; the apex of the 

 median segment is slightly and roundly concave; the upper 

 part at the sides broad, not forming teeth; the central keel is 

 stout ; the second cubital cellule is much narrowed at the top, 

 being there only one half the length of the space bounded by 

 the second transverse cubital and the second recurrent nervure ; 

 the second abdominal segment is not much narrowed at the 

 base. 



This species comes nearest to R. flavomarginatum, with 

 which it agrees in coloration ; it may be known from it by 

 the body being more densely pilose, and is readily separated 

 from it by the clypeus not being deeply grooved in the 

 middle. 



Rhynchium rugolatum, sp. n. 

 Long. 12-14 mm. 



Hab. Barrackpore (Roihney), Poona (Wroughton), Khasia 

 Hills. 



This species closely resembles R. brunneum. The differ- 

 ences between the two are best expressed in synoptical form : — 



9 . — Mesonotum shining, sparsely and slightly punc- 

 tured ; the scutellum impunctate ; the sides of the 



median segment with sharp teeth brunneum. 



Mesonotum and scutellum closely rugosely punc- 

 tured ; the sides of the median segment without 

 teeth rugolatum. 



£ . — The top of the clypeus transverse ; the oblique lower 

 part shorter than the upper part; the middle femora 



not narrowed and twisted at the base rugolatum. 



The top of the clypeus rounded, its narrowed lower 

 part longer than the upper; the middle femoia 

 narrowed and twisted at the base brunneum. 



The head rufous : the ocellar region broadly (the mark 

 slightly narrowed and rounded behind), the part between the
