70 Dr. Sharp on the Rhynehophorous 



Osaka, July 7th, 1881 ; Miyanoshita, May, 1880. One 

 pair. Although not taken together, I have no doubt 

 they are the sexes of one species. 



Eugnamptus Jlavipes, n. s. 



Niger, thorace subvirescente, capite Isete cupreo, elytris an- 

 tennisqiie fusco-testaceis, harum clava pedibusque flavis ; corpore 

 supra pedibusque minus dense setosellis. Long, cum rostro, 

 4^ mm. 



The elongate joints of the club of the antennae are paler than the 

 other joints ; the head is sparingly punctate, canaliculate in front ; 

 the thorax is subcylindric, longer than broad, coarsely but not 

 rugosely punctate. Elytra with very regular series of coarse 

 punctures, the interstices very slightly convex, impunctate. Ven- 

 tral segments shining, impunctate, with an elongate, erect, exces- 

 sively fine scanty pubescence. 



Kobe and Fukushima in July, 1881 ; two specimens.

Deporaus.

This genus is entitled to distinction from Rhynchites, 

 as has been already stated by Bedel and by Faust. The 

 character they rely on, viz., the exposure of the pro- 

 pygidium, as well as the pygidium, is, however, subject 

 to some exception, as in D. mannerheimii and some 

 others the male has only the pygidium exposed. There 

 exists, however, another more important character, for 

 in Deporaus the apices of the prosternal epimera are 

 separated by the centro-sternal piece. 



Deporaus will probably prove an extensive and varied 

 genus, as I have seen species differing much from one 

 another in appearance and colour, found in the eastern 

 tropics, that must be placed in it. 



Faust (Deutsche Ent. Z., xxxi., p. 163) places Rhyn- 

 chites tristis in Deporaus. The only certainly authentic 

 example of R. tristis at my disposal has the propygidium 

 and part of the pygidium covered by the elytra, and the 

 apices of the epimera are apparently joined ; so I have 

 placed the species in Rliynchites,
