conspicuous from the base to two-thirds of the length and the in- 

 tervals plane on the back, tectiform on the sides and posterior part, 

 and sharply punctate-scabrate. 



This species is more parallel and more slender than D. lityubris, 

 the elytra are more parallel, the pubescence is very much longer on 

 the upper side, the more tectiform costas of the elytra are plainly 

 more scabrose, and the prothorax has no traces of an outer marginal 

 keel. 



Length 13-14f mm. ; width 4J-5| mm.

DYSGEXA DECIPIENS, n. sp. 



Fuscous-black, with the elytra dark chestnut-brown, the head and 

 prothorax are covered with a very short appressed greyish pubes- 

 cence, the same appressed pubescence is also found on the 

 elytra, but is denser there and almost hides the colour of the back- 

 ground ; the slender antennae are ferruginous with the exception of 

 the basal joint which is fuscous ; closely allied to D. durbania, the 

 prothorax is similar in shape, but it is less coarsely shagreened, and 

 it has a very plain outer marginal keel ; the intervals between the 

 punctate striae are much more plane even on the sides and the 

 posterior part, and more closely and finely scabrose. 



Length 15 mm. ; width 5^- mm.

DYSGENA PLEBEIA, n. sp. 



Chestnut-brown, not metallic ; head and prothorax clothed with 

 greyish fiavescent hairs, head roughly but not closely punctured in 

 the frontal part, but more closely in the anterior and on the neck; 

 prothorax a little dilated laterally and also more rounded in the 

 anterior than in the posterior part, sharply carinate laterally and 

 covered with irregular, deep punctures closely set and separated by 

 equally irregular, raised walls ; scutellum closely punctate ; elytra 

 sub-parallel with the striae plainly punctured for two-thirds of the 

 length, the intervals are plane, scabrose-punctate in the anterior 

 part, and scabrose behind, each one of these punctures bear a some- 

 what long hair ; the pubescence on the legs is nearly as long as on 

 the elytra, and the third antennal joint is in one of my examples 

 very slightly shorter than the fourth, and longer in another. 



Allied to D. dccipiens, but the antennas are less slender, the pro- 

 thorax is not impressed longitudinally, is much more roughly and
