1885.] COLEOPTERA FROM JAPAN. 203 



Cryptocephalus sexpunctatus, Linn. 



A single specimen before me I am unable to separate from the 

 normally coloured individuals of this species, which has been reported 

 also from Siberia. 



Cryptocephalus fulcratus, Germ. 



The occurrence of this species in Japan extends still further its 

 geographical distribution, it having been also recorded, like the pre- 

 ceding species, from Siberia. Two specimens obtained at Jensai do 

 not differ from the European form except in their rather larger 

 size. 



Cryptocephalus nobilis, Kraatz. (Plate XI. fig. 7.) 



The description of this species, given by the author in tbe 

 'Deutsche ent. Zeilschr.' 1879, agrees perfectly with the ten speci- 

 mens obtained by Mr. Lewis at Kiga, Suyama, and Subashiri. The 

 insect is of a shining black colour, with two transversely shaped 

 yellow spots at each elytron (one slightly before the middle, the 

 other at the apex). The antennae in the male are exactly as long as 

 the body, but shorter in the female, and the four or five lower 

 joints are testaceous ; the punctuation of the elytra is strong, and 

 arranged in close but not very regular rows. The specimens which 

 served Mr. Kraatz for his description were obtained from the Amur 

 country. 



Genus Pachybrachys, Suffr. 

 Pachybrachys erudita, Baly. 



Pachybrachys donUzil, Harold. 



A great many specimens of this apparently very variable species 

 were obtained au Tensai, Wada toge, Nikko, Kurigahara, on sallow. 

 The specimens which served Mr. Baly for his type have the elytra 

 almost spotless ; between tliis and almost black-coloured individuals 

 there is every intermediate degree before me, the most frequent form 

 being that in which the disiv of the elytra is occupied by a longitu- 

 dinal broad piceous or black band, leaving only the sutural and 

 lateral margin of the testaceous ground-colour ; the thorax varies 

 equally in colour, from a well-distinguished M-shaped mark to being 

 almost black with two narrow yellow basal spots. I have no doubt 

 that one of these named varieties is identical with P. donitzi, Harold, 

 as all other characters agree with the description of this author. 



Genus Leprotes, Baly. 

 Leprotes pulverulentus, n. sp. (Plate XI. fig. 9.) 

 Oblong, black, covered with white excrescences ; three basal joints 

 of the antennae and the labrum fulvous. Head and thorax finely 

 rugose-punctate ; elytra more strongly semipunctate-striate. 

 Length 3-3| Unes.
