rather less narrow and deep. There is also a close affinity 

 with E. p)olitus Gerst., but E. fro/ernus is a larger species 

 with wider margins to the elytra, of which the apical angles 

 are very sharp and convergent. The hind angles of the 

 prothorax are less produced in the male, the front tibiae 

 are not deeply grooved externally, as in that species, and 

 the last ventral segment is not acutely notched in the 

 middle. 



CIcnus iStictomela. 

 This genus seems to be pecuHar to Ceylon and its species 

 have hitherto been found only by Mr. George Lewis. A 

 third representative is " Spathonieles " inflattis GJorh., 

 which has the characteristic heavy build, narrow loosely- 

 jointed antennal cUib and tumid shoulders of the other 

 two. 



Genus Amphix. 

 The types of Bates' monograph of this genus are in the 

 British Museum. A. gersfaeckeri is not, as supposed by 

 Cziki, a form of A. vestitus Panz., nor are circimicincHis 

 and robuslus of Bates varieties of A . discoideus F. 



Genus Indalmus. 

 The distribution of species between the two genera 

 Ancylopus and Indcdmm is quite unnatural. It seems to 

 have been decided entirely by the appearance presented 

 by the front coxae, which are said to be contiguous in 

 Ancyhpus and separated in Indalmus. In reality there 

 is always a thin lamina between the coxae and this differs 

 to a slight extent in its breadth, but the variation is so 

 small that, in the absence of any other and sharper dis- 

 tinctive character there seems no reason to make an 

 arbitrary break in the series of stages which connect the 

 two extremes. The mesosternum exhibits a variety of 

 forms which are much more marked than those of the 

 prosternum, but have no relation at all to the present 

 grouping of the species. The typical species of Ancyhpus 

 {A. melanocephalus Oh v., of which A. hisignatus Gerst., is 

 probably a colour-variety) quite obviously stands apart 

 from the rest, which caimot at present be easily separated, 

 although it may perhaps be found desirable in the future 

 to devise additional genera. I therefore transfer to
