226 On some new Species o/'Prionidae. 



rather large for this genus and provided with a well-marked 

 dorsal ridge. Pronotum slightly angulate behind the middle 

 on each side, finely and very closely punctured except over a 

 large median area somewhat roughly pentagonal in shape, of 

 which one side is contiguous with the base, one angle with 

 the anterior margin. This area is somewhat glossy and 

 sparsely punctured. The elytra, of a reddish chestnut-colour, 

 are glossy and rather thickly and distinctly punctured. The 

 underside of the prothorax is very closely and finely punc- 

 tured, and bears some minute and sparsely scattered granules ; 

 the sides of the breast are rather thickly, the middle more 

 sparsely, punctured ; the abdomen is rather sparsely punc- 

 tured, except along the middle of the last segment, where the 

 unctures are larger and more thickly placed. The basal 

 joints of the antennas are rather sparsely punctured, and the 

 joints from the third to the fifth are slightly flattened above. 



This species is distinguished from E. antennalis, Saund., 

 by its broader form, its larger mandibles^ the shape of the 

 central shining area of the pronotum, and the less closely 

 punctured antennal joints. In antennalis the pronotum has, 

 in addition to the central shining area, two lesser areas cut 

 off from it, one on each side. 



JEgosoma Bowringi, sp. n.

This species may be distinguished from JE. sulcipenne. 

 White (to which it appears most nearly allied), by its close 

 covering of short fulvous or greyish-fulvous pubescence. In 

 sulcipenne the pubescence is much sparser, and allows the 

 colour of the derm to show up distinctly, and on the elytra is 

 confined to linear tracts along the depressed groove-like 

 intervals between the costge ; whereas in the present species 

 it covers the whole upper surface, with the exception of the 

 raised lines. In the females a reddish callous spot is to be 

 seen on each side of the prothorax just under the lateral 

 carina.
