Coleopterous Fauna of Japan. 419 



evklenter striatis, stylis punctatis, interstitiis (vix punc- 

 tatis) postice convexis. Long. 1^ mm. 



About the size of (7. pygmceum, but narrower and less 

 convex tlian that species, and remarkable from the very 

 distinct striaj of the elytra. The legs, antennae and palpi 

 yellowish. The head and thorax are finely and not densely 

 punctured ; the base of the latter is also furnished Avith a 

 row of closely-placed, fine but distinct punctures. On the 

 under-surface the centre of the metasternum is raised as a 

 large, flat, almost pentagonal surface, finely and sparingly 

 punctured and shining ; the mesosternal plate is broad and 

 very strongly punctured. The anterior tibise are without 

 any notch on the outer edge. 



Of this very distinct species I have seen only two indi- 

 viduals, one of which I have had the misfortune to lose at 

 the moment of completing ray description. The structure 

 of its meso- and meta-sternal plates will perhaps cause the 

 species to be ultimately separated from Cercyon as a dis- 

 tinct genus. 



Cyclonotum simplex, n. sp. Rotundato-ovale, nigrum, 

 nitidum, crebre punctatum, antennarura basi, palpisque 

 testaceis ; tarsorum posticorum articulo primo, 2" duplo 

 longiore. Long. 5 mm. ; lat. 3J mm. 



This species very greatly resembles C. hispaiiiciim, 

 Kiister, and is about the size of that species, but is nar- 

 roAver in proportion to its length ; it has the scutellum 

 much narrower than in C. hispanlcum, the tibias rather 

 more slender, and the basal joint of the four hinder tarsi 

 longer ; the punctuation of the elytra is scarcely so coarse 

 tOAv-ards the extremity. In all other respects, so far as 

 I can see, it agrees Avith C. hispanicum. 



I have this species fi-om China as Avell as Japan. 



Cyclonotum hrcve, n. sp. Subhfemisphericum, nitidum, 

 nigrum, crebre punctatum, antennarura basi pal])isquc tes- 

 taceis, pedibus piceis. Long. 3g— 4 mm. ; lat. 2^ mm. 



This species is closely allied to C. orhiculare, but is less 

 oblono- and more hemispheric in form, and has the palpi 

 yeUow; the punctuation of the elytra is a little coarser; 

 the hind tarsi are nearly similar in length m the two 

 species, but are just a trifle longer in C. breve. Prom 

 C. simplex the smaUer size, more hemispheric lonii.
