278 CHBYSOMELIDJS. 



Allied to 0. fulvipes, Baly, but larger, the head similarly 

 pubescent, but the elytral sculpturing and the colour of the legs 

 quite different. 



479. Chlamys andrewesi, Jac. Ann. Soc. Ent. Belg. xlvii, 1903, p. 93. 



Black; antennae and legs (posterior femora excepted) fulvous*. 



Head flat, rugosely punctured ; eyes acutely notched ; labrum 

 fulvous ; antennae with the last seven joints gradually widened. 

 Thorax transverse, lateral margins straight, middle portion raised 

 into a round elevation, top of the elevation bounded by a rather 

 deep oblique groove ; entire surface evenly and closely rugose- 

 punctate, puncturation at sides stronger than within lateral 

 grooves, top of elevation with some short oblique ridges at sides of 

 central sulcation. Scutellum with hind angles strongly produced. 

 Elytra much more deeply and coarselv punctured, more shining 

 than the thorax ; middle of base with longitudinal ridge to middle 

 of disc, connected there with another ridge that runs parallel with 

 the first ridge upwards to the shoulders, where it becomes indistinct ; 

 a strongly raised transverse tubercle near suture behind the middle, 

 connected inwards with a short ridge which joins the basal ridges 

 at their lower posterior connection ; apical portion of elytra with 

 another longitudinal triangular ridge close to the suture and more 

 ridge-like tubercles near lateral margins ; interstices everywhere 

 rugosely reticulate. Pygidium finely rugose, with obsolete longi- 

 tudinal grooves at the sides ; the sculpture of the body beneath 

 similar. 



Length 4| mm. 



Hob. Southern India : Nilgiris, Anaimalais. 



Genus EXEMA.

Type, E. intricata, Kollar, from Brazil. 



Range. North and South America ; Africa ; India ; Malacca. 



Characters similar to those of Chlamys, but the antenna? are 

 dentate from the sixth joint outwards. Thorax generally with 

 longitudinal ridges. This is an ill-defined genus, and can scarcely 

 be separated from Chlamys solely on the variable structure of the 

 antenna?. I have kept it separate as a matter of convenience 

 only.
