COLEOPTERA NEW TO THE FAUNA OF JAPAN. 153 



Grammoptera gibhicollis, Bles. — I have this species from 

 Tsusima (Vinegar Island). 



Donacia ceraria, Baly, 1869 = D. lenzi, Schonfeldt, 1888. — 

 Baly was in error in assigning this species to the Chinese D. 

 ceraria, Baly. Schonfeldt does not refer to Baly's species in his 

 description, but there is hardly any difference between the two, 

 except that the antennae are longer and more slender in D. lenzi 

 than the other. It is abundant in the Kobe ponds and in lakes 

 about Kioto and Osaka. It feeds on a water-lily. 



Donacia impressa, Paykull. — I obtain this from a small col- 

 lection made on the Ishikari Kiver. I have a specimen also which 

 I brought from Sapporo, which is not separable from examples of 

 this species. 



Pachybrachys donitzi, Harold = P. eruditus, Baly. — This 

 species is so exceedingly variable in colour that no specific cha- 

 racter can be based upon coloration alone. Harold was probably 

 misled by having some specimens which did not quite coincide 

 with Baly's description. 



Lema melanopa, Linn. — This Eurasian species is scarce in 

 Japan. I found it at Niigata, and I swept five examples on the 

 Shiwojiri-toge in July, 1881. 



Luperodes 23rceustus, Motsch., Sol. Eeis. ii. 1860, p. 232, t. 11, 

 f. 19. — This species, by an oversight of mine, was not recorded 

 by Mr.- Jacoby in his memoir on the Japanese Phytophaga. 



Hispa japonica, Baly, 1874 = H. angulosa, Solsky, 1872. — 

 I have an undescribed species which resembles the above very 

 closely. 



Coptocycla crucifera, Kraatz, 1879 = C. thais, Bohem., 1862. 

 — The first name represents a variety in which the dark markings 

 have disappeared. Dr. Kraatz has kindly sent me his type for 

 examination, and I have a corresponding specimen which was 

 taken in association with typical examples. 



Languria genicidata, Har., 1879 = L. lewisii, Crotch., 1873. 



Cyrtotriplax niponensis, Lew., 1874 =Triplax maackii, Sols., 

 1871. — This is the commonest species of the genus in Japan. 



Coniopoda, Gorham = Danae, Eeiche. 



Cyanauges, Gorham = CcBnomyclms, Gorham. — The latter 

 name is suggested by Mr. Gorham, Cyanauges being preoccupied 

 in Diptera. The food-plant of Ccenomyckus is an Agaricus, allied 

 to, if not the same as, the European A. atro-cceruleiis of authors. 



Ithone mirahilis, Motsch. — I saw this species in immense 

 profusion between Sendai and Awomori. I saw it for several 

 days together, in clusters on the newly-erected telegraph-posts, 

 when journeying from Awomori to Sendai. Out of these count- 

 less numbers I obtained two examples with the elytra entirely 

 black. The species was originally recorded from Siberia. 



Hippodamia tredecimpunctata Linn. — I introduce this species 

 on specimens I found at Nikko and Kashiwagi.
