TETBAOMMATUS. 103 



longitudinal impressions on the disc, one anterior and two pos- 

 terior, dark brown ; elytra yellowish testaceous, with two bands 

 and the sutural border between them dark brown ; the first baud 

 arises from the suture at about the middle of its length, curves 

 outwards and backwards and ends in a transverse spot at the side ; 

 the second band begins at the suture at about one-third from 

 the apex and is directed obliquely towards the side but does not 

 reach to the outer margin. Head rather densely punctate and 

 opaque. Antennae sparsely ciliate, ferruginous at the base, paler 

 towards the end ; second joint about one-third of the length of 

 the third ; third slightly longer than the fourth and subequal to 

 the fifth. Prothqrax of <3 about one-third longer than its width 

 across the middle ; slightly rounded and armed with a small spine 

 at the middle of each side, constricted at base, and marked there 

 with a rather deep transverse groove, which is slightly arched 

 forwards in the middle and has two longitudinal impressions that 

 run from it to the middle of the disc ; the upper surface more or 

 less opaque and somewhat densely punctate, the puncturatiou 

 finer and closer towards the sides. Elytra subnitid, densely 

 punctate, and sparsely pubescent, rounded at the apex. Body 

 beneath reddish testaceous, the abdomen paler ; prosternum nitid, 

 transversely striated near its front margin, distinctly but not very 

 densely punctured posteriorly. 



Length 8-11 ; breadth lf-2 mm. 



Hab. Andaman Is. ; Tenasserim: Thagata (Fed); Siam (Mouhot).

Brownish black, the prothorax and ventral side of the head 

 testaceous red, the abdomen and legs varying from reddish 

 brown to very dark brown. Head rather densely punctulate. 

 Antenna? twice as long as the body in the d" ; second joint less 

 than half as long as the third; third and following joints to 

 ninth or tenth subequal in length. Prothorax somewhat rounded, 

 and armed with a small spine at each side, constricted and marked 

 with a transverse groove at the base ; its length about one-fourth 

 greater than its width across the middle ; upper surface very 

 feebly convex, slightly nitid, densely and finely punctate ; the 

 sides minutely punctulate and opaque. Elytra densely punctate ; 

 sparsely covered with greyish pubescence. 



Length 6|-11 ; breadth l^-2 mm. 



Hab. Upper Burma: Mt. Hathalin (Fea) ; Perak (Doherty); 

 Singapore. 



This species differs only in the colour of the head, base of 

 elytra, and front femora from the Bornean species T. callidioides, 

 Pasc., and it is probably only a local variety or race of the latter.
