XLI. — Revision of the S. African Species of Dinometopus, 

 Trogiops, Chaliconis, Colotes, Helcogaster, and the allied 

 Genera^ vrith an Account of their accessory (^ -characters 

 ICvleoptera' . By G. C. Champion, F.Z.S. 



[PUtes IV.- VI.' 



This paper is in continuatioa of the one on Eb^tus, £r., 

 pahli>hed in the last volume of the 'Annals.' It gires an 

 account of the remaining genera of Malachiinae represented 

 in S. Africa. The Dasytinae (including various insects 

 descril>ed as Malachiids) have been dealt with in a separate 

 article, whicli will be issued later. The matenal examined 

 is from the same sources. The (J -characters of Dinumetopus, 

 Troglups, etc.. are homologous with those found in 

 Hedybius and its allies ; but in Sphinginopalpus^ Colotes, 

 etc.. the development is transferred to the maxillary palpi.* 

 Dr. Marshall's collection is very rich in these insects, mostly 

 coUected by himself, and Dr. Peringuey has forwardetl 

 various interesting forms. With one exception, a Trogiops 

 from Xyasaland, all the species studied are from Rhoitoia, 

 Natal, or S. Africa. The E. African forms named by Pic 

 in 1919 (Melanges exot.-entom. xxxi. pp. 4-9^ are there- 

 fore not likely to be synonymous with any of those here 

 enumerated.
