In the malt', however, the elytra are almost black, shining 

 but quite unnietallic. In both there is a similar pattern of 

 yellow scaly hairs which cover the pygitliuin and under 

 surface. It is quite a small beetle, about 8 millimetres long. 



The following two new species of Pseudosinghala are 

 remarkable for colour-ditferences between the two sexes. 

 These are of the nature which J have previously described as 

 general in the i^nomalinai, viz. the males are invested with a 

 hue superimposed upon that of the females.

This is the largest Pseudosinghala yet known. It is stout 

 and globular, with the sides of the thorax more strongly 

 curved than in any other species known to me. The elytra 

 in both sexes are of a rich testaceous colour, with a small 

 yellow sjjot (sometimes divided) on each side of the suture 

 before the middle, and nearly the entire margin black, to- 

 gether with a transverse patch round the scutellum, which 

 may extend right across the elytra. The difference between 

 the sexes is that, while in the female the head, thorax, and 

 scutellum are of a very dark brown colour, in the male they 

 are suffused with a brilliant fiery lustre. The pygidium of 

 the latter also has a similar lustre, whereas in the female it 

 is, with the rest of the abdomen, unmetallic red. 



A series of specimens in the British Museum were collected 

 by the late Mr. Lamb, and the species is also in Mons. 11. 

 Oberthiir's collection.
