LONQICOKir BEETLES OF JAPAIf. 213 



griseo-pubepcens, subtus niger densius griseo-pubescens, abdo- 

 mine flavo nigro-maculato ; pedibus nigris nitidis ; femoribus 

 dimidio basali tibiisque (interdum) medio flavis. Capite creber- 

 rime thorace paullo parcius punctatis, elytris confluenter vel 

 rugulose punctatis apice sinuato-truneatis utrinque bidentatis. 

 Femora c? omnia, $ 4 posteriora subtus dentata. Long. 

 12-13 millim. c? ? . 



Ciiiuzenji ; Niohozan. 



Differs from Cr. ussuriensis (Blessig) of tbe Amur region only 

 in tbe yellow colour of the abdomen, and would perhaps be better 

 considered as a local variety of that species. It is, however, a 

 larger and more brightly-coloured insect. The conspicuous 

 tooth beneath the femora, similar to that of many Donacics, which 

 both species wonderfully resemble, appears not to have been 

 noticed by Blessig and Kraatz, the two authors who have men- 

 tioned Cr. usstmensis : a specimen I obtained from probably the 

 same source as those authors has femora like the Japanese form. 



ToxoTiKus, nov. gen. 



Eacies gen. Toxoti. Caput post oculos elongatum paullulum 

 tumidum sed vix ad coUum augustatum, antice verticale. Oculi 

 prominentes, parum emarginati, a mandibulis sat distantes, sub- 

 tiliter granulati. Palpi apice minime dilatati. Antennae S ? 

 corpore longiores, articulis 3-4 subsequalibus quam 5-10 paullo 

 brevioribus, undecimo multo longiori, contra oculorum marginem 

 anticum insertse; tubera autennifera elevata. Tliorax relative 

 parvus conoideo-subcylindricus, antice et postice modice con- 

 strictus, tuberculo laterali utrinque obtuso, angulis posticis 

 nullomodo prominentibus. Elytra postice paullo attenuata apice 

 rotundata. Prosteruum inter coxas angustissimum, mesosternum 

 oblongum subconvexum. Pedes fere sicut in Toxotis, sed tibiis 

 posticis apice multo minus oblique truncatis. 



Distinguished from the allied genera by the form of the pos- 

 terior part of the head and by the forehead being abruptly vertical 

 from the base of the antennae. The male resembles at first sight 

 small individuals of the same sex of Toxotus meridianus.

 Elongatus, postice modice angustatus dorso subplanatus, supra 

 dense subtiliter aureo-pubescens, pube thoracis longiori, incum- 

 benti, laetius aurato ; subtus griseo-pubescens. Eulvus, capite,
