tliau broail, flattened behind, mesial line elevate, smooth before middle ; angle of 

 carina less strongly ronnded tliau in Indian Rawasia. Elytra more than double 

 as long as broad, very coarsely ijnuctate-striate ; the grey dots somewhat enlarged 

 behind middle. Tarsal segment 2 as in R. ritsemae and aiumlipcs, but 3 not 

 so large as in these species. 



Length (head excl.) : Id mm. 



Hab. Benito, French Congo. 



Two pairs. 



6. Rawasia fulvescens sji. nov. 



(? ? . Differs from the preceding as follows : 



Stouter ; tomentnm dense, dirty clay-coluur ; antenna much shorter, esijecially 

 in c?,not ringed with grey, with the eighth segment {S and ?), or also the ninth 

 (only S) very much shorter than in finsescens ; rostrum more deeply impressed 

 basally, and mesial line of pronotum not elevate. 



Length (head excl.) : "^ — 10 mm. 



Hab. Benito, French Congo. 



One cJ, two ? ?. 



Derographium gen. nov. 



S. Rostrum similar to that of Tophoderes and Rawasia, not narrowed towards 

 end, slightly bisinuate at apex, the corners with a small excision, base shallowly 

 concave, no carinae or grooves. Frons broad. Eye lateral, slightly oblique, sinuate. 

 Antenual groove large, covered by the enlarged lateral edge of the rostrum, not 

 continued on the underside. Antenna reaching beyond base of elytrum ; segment 1 

 incrassate, -I small, the following ones thinner, 3 = 4= 1 +2, 5 and G and 7 shorter 

 than those, T slightly dilated, 8 to 11 forming a broad club, 8 trapeziform, longer 

 than broad, 9 and 10 broader than long, 9 longer than lo, 11 ronnded, not so broad 

 as 10, G to 10 beneath rather densely and long hairy. Pronotum convex, much 

 broader than long, with large penicillate mesial tubercle ; sides converging in 

 front, sinuate behind ; carina rather close to base, almost reaching ajjex laterally, 

 angle almost 90°, with the tip rounded. Elytra short, with penicillate tubercles. 

 Prosternum short. Intercoxal process of mesosternnm almost vertical, sinuate, 

 broader than long. Tarsi shorter than tibiae, segment 1=2 + 3, 3 rather broad. 



Type : 1). fuloum. 



Differs from Tophoderes essentially in the antenna, eye, antennal groove, etc. ; 

 from Gjjnaiidrocerus in the position of the pronotal carina and iu the short body ; 

 from Rawasia in the shape of the tarsi and in the sinuate eye. 



7. Derographium fulvum sp. nov. 



S. Brown, densely covered with a yellowish brown tomentnm, indistinctly 

 sjiotted grey. Antenna black, witli the exception of segments 1 and 2. Tibiae with 

 brown middle spot and blackish tip. LTpperside finely chagreened. Elytrum 

 without j)unctate stripes ; a large basal convexity which bears two brushes of stiff 

 hairs ; two small penicillate tubercles, one in and the other behind the middle ; 

 traces of tubercles towards the sides ; apex rounded. Pygidinm somewhat shorter 

 than broad, rounded. Last abdominal segment a little impressed, slightly sinuate.
