posterior angles, which consequently are very prominent and 

 directed backwards and outwards. The fore part is impressed 

 above. The nnargins have about nine acute teeth. The 

 elytra are at the base a little broader than the thorax, but are 

 distinctly broader a little behind the middle, and then again 

 somewhat narrower, convex at the base, flattened posteriorly, 

 leaving the sutural region (between the suture and the first 

 costa) somewhat raised above the rest of the surface till near 

 the apex ; there is a second costa not much removed from the 

 first, and the space between them is concave. There is a 

 well-marked sublateral obtuse costa, which extends nearly to 

 the apex ; the side of the elytra outside this costa is nearly 

 perpendicular, the margin itself being reflexed. The usual 

 third costa is absent, the space between the second costa and 

 the lateral one being gently concave. All the basal region is 

 rugose, and the rough sculpture is continued for some distance 

 down the sutural region and on the lateral costa. The pro- 

 sternal process is very coarsely rugose. The metasternum is 

 closely and finely punctured and pubescent. The abdomen 

 is somewhat dull, closely and very finely punctured, with 

 the apical margin of the segments smooth and shining. The 

 femora are sparingly asperate-punctate, with a few very small 

 spines beneath ; the tibiee are rough, with a few very small 

 spines on the inner edge.

Hab. Java [coll. Dejean). 



M. Thomson has in his " Typi " (Rev. Zool. 1877, p. 273) 

 described a species under the name of M. serricoUis, Dej., to 

 which I have alluded above. I think, however, that his 

 insect cannot be the male of the species I have just described, 

 and 1 therefore propose to call the female Dejeanian example 

 M, Dejeanii. 



It is closely allied to M. Wrigldii (Waterh. Ann. & Mag. 

 Nat. Hist. V. 1880, p. 414), from the Seychelle Islands ; and 

 if it were not for the colour of the elytra and the locality, I 

 should have considered them as sexes of the same species. 



Macrotoma Cowani^ sp. n. 



^ . Black, with the elytra and abdomen dark brown. Head 

 very coarsely rugose. Antenna ^oug, reaching beyond the 

 apex of the elytra ; the first joint a trifle more than twice as 

 long as broad, rugose ; the third joint moderately asperate, 

 with some very small acute tubercles below, as long as the 

 fourth, fifth, and one quarter of the sixth joints taken 

 together ; the fourth to eighth joints are very finely punc- 

 tured, the punctuation obscure on the fourth and fifth joints,
