new forms amongst these families than of those genera which are 

 included to the end of the true ChrysomeHnx, and further researches 

 will no doubt greatly increase their number. A certain number of 

 species which are present only in single specimens seemed to me to 

 be so closely allied to certain European forms, especially to species 

 of the genus Longitarsus, which contains already a great many very 

 difficult species, that their description would have only increased the 

 difficulty of determination, and I have thought it best to abstain 

 from describing them till more material was at hand. I have added 

 a list of the Phytophagous Coleoptera of Japan (to the end of the 

 Galerucidae) as far as at present known, so many additions having 

 lately been made, that a clearer idea may be gathered of their 

 number. There is, however, little doubt that this list will be in 

 future greatly extended, and that especially still more species will be 

 found which are inhabitants of Japan and the northern parts of 

 Asia on one side, and the Malayan region on the other. 



Genus Mantura, Stephens. 

 Mantura japonica, sp. nov. 



Black below ; the basal joints of the antennae, tibiae, and tarsi 

 ferruginous ; above dark blue ; thorax strongly punctured ; elytra 

 deeply punctate-striate, the interstices flat. 



Length 1 line. 



Head remotely but deeply punctured ; antennae extending beyond 

 the base of the thorax, the first four joints fulvous, the basal one 

 stained with bluish-black above, the terminal joints entirely of that 

 colour. Thorax twice as broad as long, the sides straight at the 

 base, rounded towards the apex, rather strongly deflexed ; a distinctly 

 impressed longitudinal groove extends upwards from the sides of 

 the base to nearly the middle ; disk covered with deep and strong 

 punctures, more closely at the sides than at the middle. Elytra 

 rather convex, subcylindrical, regularly and deeply punctate-striate. 



Hakodate. 



Allied to M. obustata, Gyll., but the head and thorax much more 

 strongly punctured, which gives a more rugose appearance to these 

 parts ; the punctures of the elytra are also more closely approached 

 and of a more rounded shape. As these characters are the same in 

 all the specimens before me, I thought it best to separate them 

 specifically. 



Mantura fulvipes, sp. nov. 



Black below ; the four basal joints of the antennae, and the legs 

 fulvous ; above blackish-blue ; thorax coarsely punctured ; elytra 

 strongly punctate-striate. 



Length 1 line. 



Head deeply and rather closely punctured ; terminal joints of 

 the antennae thickened, pitchy black ; four lower joints fulvous. 

 Thorax transverse, very convex, the sides strongly rounded and 

 dilated ; surface closely fbveolate-punctate at the sides, more remotely
