402 On neic Species o/" Ilisteridje. 



Lew., and depistor, Mars. I have found depistor commonly 

 in Japan and China, but all tlie specimens 1 have seen are 

 wholly black. The other species have red elytral markings, 

 but wholly black varieties are very common amongst them. 



Genus Atholus, Thomson, Skand. Col. iv. p. 228 (1862). 



" Prosternum pone coxas anticas haud dilatatum. Mesostemum 

 antice rotundato-truncatum. Mandibular angulo dorsali acuto. 

 Prothorax stria marginali plerumqne medio interrupta, subtus 

 fovea antennali profunda, bone determinata. Pygidium inflexum. 

 Elytra stria laterali nulla vel abbreviata. Tibiae anticse sxdeo 

 tarsali recto, posteriores biseriatim spinosse." 



Thomson founded this genus in 1862, but until now it has 

 not been acknowledged or utilized. The name appears as a 

 synonym in the Munich Catalogue, 1868, and although I 

 recently declined to recognize it (Ann. & Mag. Nat. Hist. 1905, 

 xvi. p. 341), I think now that it is well to adopt it. The three 

 most important characters are the narrow prosternal keel, 

 the antcnnal fossae, which are deep and not quite circular, 

 and the truncate mesosternum. The species which may be 

 referred to it are numerous and widely distributed both in the 

 Old and New World, viz. : — Ilister cequistrius, bi/rons, cara-
