not seem essential for mention among a much smaller num- 

 ber of species, and the discovery in the case of some charac- 

 ters that they are less nseful for purposes of tabulation than 

 they appeared in dealing with less numerous forms. I do 

 not think that my former papers contained more than a very 

 small number of actual errors ; these, however, will be cor- 

 rected under the heading of the species affected by them {e.g., 

 H. insignu, Blackb.). But it is possible that here and there 

 slight discrepancies of terms may be found between some of 

 the descriptions in my former paper and those used now (such 

 as "'fiiie" or "not very fine" in respect of sculpture), arising 

 from species now being grouped among many that were for- 

 merly not known to me, and to obviate confusion from that 

 inevitable difficulty I have in this present Revision indicated 

 by an approximate counting of punctures exactly what is 

 meant in each case by such terms as "close," "sparse," "fine," 

 vel cet. 



Tabulation of the distinctive characters of Heterotiyces 

 of Group III. : — 



A. Front of clypeus not having a deep 

 excision. 

 B. Labrum not visible (head viewed 

 obliquely from behind). 

 C. Hind femora not having a tooth 

 before the apex. 

 D. Hind femora wide with 2 con- 

 spicuous rows of punctures be- 

 tween which is a wide, almost 

 unpunctured space. 

 E. Hind row of punctures on 

 hind femora widely spaced 

 and not more than about 10. 

 F. Front of clypeus truncate 

 or lightly sinuate. 

 G. Sides of prothorax 

 straight behind middle, 

 • hind corners genuinely 

 (though not sharply) rec- 

 tangular 



GG. Sides of prothorax more 



or less arched behind 



middle, hind corners not 



rectangular. 



H. Elytra (outside sub- 



sntural stria) non- 



striate. 



I. Elytral puncturation 



squamose 



II. Elytral puncturation 

 non-squamose. 



J. Basal edging of pro- 

 notum strong and 

 conspicuous protervus, Blackh. 



piceo-niger. Mad. 



corpulentus, Mad.
