MACEOMA. 21U 



specimen was found in a red ants' nest at Sigirva, Ceylon, by 

 Mr. R. C. Punnett. It is remarkable that this very widely-distributed 

 species should be found only in the north-east and extreme south 

 of our region.

Westio., Thes. Ent. Oxon. 1874, p. 12, pi. vi, fig. 8. 



Black, with the clypeus and an angular prolongation between 

 the eyes, the lateral and hind margins of the pronotum (except a 

 small black spot in the middle of each lateral border), the sides of 

 the metasternum and hind coxse, and the antenual club yellow. 



The shape is very convex and moderately elongate. The liead 

 is coriaceous, with the front of the clypeus rounded and the 

 mentum horizoutal. The pronotum is rather sparingly and finely 

 punctured, rather transverse, with the sides strongly bisinuated 

 and the basal margin slightly angulated in the middle. The elytra 

 are uniformly convex and finely and irregularly punctured, except 

 at the extremities, which are strigose. The pygidium is smooth, 

 w ith a sharp median carina and a rounded boss on each side. The 

 sternal process is very short, the metasternum slightly strigose and 

 pubescent at the sides, and the abdomen almost smooth. 



cJ. The abdomen is strongly arched and deeply grooved, and 

 the two penultimate segments are closely punctured and hairy in 

 the middle. 



Length 19 mm. ; breadth 10*5 mm.

Black, with the clypeus and an angular prolongation between 

 the eyes, the lateral margins of the pronotum (except a small 

 median black spot on each side), and the elytra (except narrow 

 sutural and lateral margins and a broad posterior margin) yellow. 

 There is a slight expansion of the black lateral margin just beyond 

 the middle, a black patch sometimes appears upon the suture 

 opposite this, and in some specimens a transverse band is formed 

 by their fusion.
