I have dedicated this interesting species to Mr. H. J. 

 Kol be of the Berlin Museum. 



Obs. Japan has, as far as 1 know, three species of 

 Helota , two of which belong to the Gemmata-group, These 

 two bear, up to this day, each the name of helota gem- 

 mata Gorh. although they are clearly distinct. 



The true Helota gemmata , described by Gorham in the 

 Transactions of the Entomological Society of London for 

 the year 1874 (p. 448), has, besides striking differences 

 in the sculpture of the elytra , the anterior tibiae in the 

 male provided with a compressed apical dilatation on the 

 inner margin of the under surface , and in the female 

 acute apices to the elytra aud an apical depression on the 

 last ventral segment. 



In the second species, which is the one described by 

 Kolbe (after a female specimen from Corea) under the name 

 of Helota fulviventris *), the male does not possess the com- 

 pressed dilatation on the apex of the anterior tibiae , and 

 the female has not only the apices of the elytra separately 

 rounded (not produced), but it wants moreover the apical 

 depression on the last ventral segment. — Of this latter 

 species a very badly drawn figure is published on plate 133 

 of Waterhouse's Aid to the Identification of Insects.

 have examined a female specimen of this species from the Amur, kindly sent 

 to me for comparison by Mr. Kolbe. — The specimens from Shanghai, alluded 

 to by Mr. Lewis (Trans. Ent. Soc. London. 1874, p. 449), will probably prove 

 to belong either to fulviventris Kolbe or to Kolbei Rits., the latter species being 

 already known from that locality.
