except near the margin and the inner and outer edges. The

 latory striae.

Hub. N. Madagascar : Antongil Bay, Vohdmar. 



A female specimen in the British Museum was taken at 

 Antongil Bay, and Dr. Sicard has found both sexes at 

 Vohdmar. The female specimens from both localities are 

 completely opaque above, but the single male, although less 

 glossy than the other species o£ the genus, is not opaque. 

 Whether the difference is accidental or characteristic we 

 must await further observation to determine. The clypeus- 

 is rather shorty very little attenuated in front, feebly im- 

 pressed, but not toothed at its apex. The pronotum is almost 

 devoid of punctures at the lateral margins, except the front 

 angles, and at the middle of the base. The punctures of the 

 elytra are not very large and not arranged in distinct rows^

 margine externo medio fere angulato, angulis posticis bene mar- 

 catis, fere rectis, basi leviter trisiuuato ; scutello fere laevi ; 

 elytris grosse et crebre irregulariter annulato-punctatis, lateribus 

 Isevigatis, apicibus obsolete punctatis, stria suturali integra pro- 

 funde incisa ; propygidio postice producto, striis stridulatoriis, 

 utrinque subtilioribus laete et dense praedito; pygidio nitido, 

 lateribus subtiliter rugulosis; mandibulis apice profunde fissis, 

 extus trilobatis :
