20fi. Pohjpleurus geminatus ^Dej. according to the tj-pes in 

 Mr. F. Bates's collection, is the smaller species Avith narrower 

 prothorax. 



20t. According to Mr. F.Bates the genera Calcar, Zolodinus, 

 and Centorus are exceptions to the ordinary structure of the ventral 

 segments in the allied genera, the hind margin of the segments 

 not being membranous, but entirely corneous, as in Asidida?. 



208. Tenebrio castaneus, as pointed out to me by Mr. Bates, 

 agrees with the genera just named in the ventral segments being 

 entirel}^ corneous, but is peculiar in having the eyes completely 

 divided by the eyes as in Blapstinus. It evidently indicates a new 

 genus, to be associated with the others as a distinct tribe, Cal- 



CARINI. 



209. Pachyurgus iEREUS (Mels.) seems to be Encyaleslhes 

 hrevicornis Motsch., found in Java, Gilola, Malaysia ; it is there- 

 fore to be stricken from the list. 



210. Ephalus Lee. does not in the least resemble Leichenum, 

 with which.it is united by Gemminger and Harold. 



211. RuiPiDANDRUS Lee. I have seen a species from Guada- 

 loupe in the collection of Mr. Salle, to whom I am indebted for 

 the remark that Melolontha paradoxa Beauv. is the same as 

 R. fiabellicornis. Vide No. lOG. 



212. IcTiSTYGMA Pascoc, from Australia, seems hardly different 



from EURYGENIUS. 



213. Isghalia Pascoe (1860) is Eupleurida Lee. (18G2). The 

 North American species dift'ers from the Bornean one chiefly in 

 color, the latter being of a uniform indigo color, while the former 

 is black and yellow. 



214. Macr atria linearis Newm. The base of the prothorax is 

 not narrower than the widest part in front of the middle, and the 

 species does not seem to differ from the common M. murina. 



215. EusTROPHUS BicoLOR. The proper authority for this species 

 is Sa}', the first describer; Mycetophogua bicolor Fabr. is probabl}' 

 a Platyderaa. 



215a. ScRAPTiA. Several allied foreign genera have the eyes 

 hairy like X^dophilus, Stereopalpus, etc. 



21 G. Anaspis collaris Lee. should be compared with the Euro- 

 pean A. RUFICOLLIS. 



217. Toposcopus Lee. I saw in the collection of Mr. Fry an 

 Australian species of this genus, and also a new genus having
