Macroma maculicollis, IJ'estw., I. c. p. 13, j)l. vi, fig. 10. 



Black, with the head, pronotum and front legs partially or 

 entirely orange ; the scutellum, side pieces of the metasternum 

 and sides of the hind coxae generally bright yellow, and the 

 sides of the third and fourth abdominal segments deep red. 

 The pronotum has commonly a black median line and a large 

 black patch on each side, the latter frequently reduced to two 

 spots. 



The form is moderately long. The Jiead is coriaceous, the 

 clypeus nearly straight in front, and the mentum vertical in front 

 and rather deeper than it is broad. The jJt'otho rax is rather short, 

 not much narro^^■ed in front, w ith the sides well punctured and 

 the basal margin gently rounded. The eh/tra are distinctly and 

 irregularly punctured, with their sutural margins a little depressed 

 in front and elevated behind, the posterior end being finely rugose. 

 The piKjidium is very lightly strigose, with a median longitudinal 

 carina and a blunt tubercle on each side of it. The sternal jyrocess 

 is very short and rather broadly dilated, the sides of the meta- 

 uternum are sparingly punctured, and the abdomen is nearly 

 smooth. 



S . The abdomen is very strongly arched and channelled 

 beneath. 



Lencjtli 16-20 mm. ; breadth 9-10 mm.

Yar. cingalensis, nov. 



Entirely black, except the clypeus, parts of the front legs, the 

 side-pieces of the metasternum and the sides of the hind coxk and 

 third and fourth abdominal segments. 



Ceylon. 



This species, though very variable in colouring, is otherwise 

 constant. The prothorax appears in every stage between uniform 

 red and uniform black. The name Macroma javanica was given 

 to a dark form in which only the head and a narrow lateral border 

 to the pronotum are black. The darkest variety appears to be 

 peculiar to Ceylon, from which island I have seen no representative 

 of any other form. This variety is mentioned by Mr. Van der 

 Poll (Notes from the Leyden Museum, xvii, 1895, p. 132). A
