Melanolits unnvsus, Caiul. 



7'here is little to distinguish this species from M. correctus, 

 CaiKJ., except the longer third joint of the antennai and lesser 

 declination ot the prostcrnal posterior process. In .1/. annosusj 

 however, the antennae are usually red, and in M. correctus 

 they are usually fuscous. 



J/ah. Both species are from Nagasaki. 



Melanotus ocellato-punctatus, sp. n. 



Niger, subopacus, griseo-pubescens ; antennis pedibusque obscure 

 rui'o-brunnois ; capite thoraceque confcrtissime ocellato-punctatis, 

 hoc angulis subdivaricatis ; elytris puuctato-striatis, interstitiis 

 rugosis et punctulatis. 



L. Ki mill. 



Tiiis insect has tiie facies of the European Melanotus rujipes^ 

 libst., but it is darker, and the tliorax thickly covered with 

 deep occllate punctures ; the antennae have the second joint 

 short and bulbous and the third nearly as large again. 



Hah. Junsai. One example only. 



Melanotus senilis, Cand. 

 Melanotus senilis, Cand. M^m. Ac. Belg. 1864, p. 47. 



The type of this species is in the Musde de Helsingfors, 

 but there are five examples in my collection which, I think, 

 correspond to the description of it. The thorax is " creber- 

 rime et fortiter punctato," and the type measures 13 mill. 

 My specimens measure 11^-12^ mill., and some of the 

 thoracic punctures are distinctly ocellate ; the second joint of 

 the antennce (of which Cand^ze says nothing) is short and 

 bulbous, the third nearly as long again and obcouical.

Melanotus invectitius, Cand. 



Melanotus invectidus S , Cand. ^lem. Ac. Belg. 1864, p. 47. 

 Melanotus Fortmani, Cand. Ann. Soc. Belg. 1878, p. 167 ? 



The deseri})tion of M. invectitius was drawn from a single 

 male in the collection of M. Miiklin, and Candbze compares 

 both it and M. Fortnumi to M. niger, F. I think both his 

 descriptions refer to the sexes of one species. In M. invec- 

 titius the second and third joints are said to be " subffiquali- 

 bus," and in M. Fortnumi " eequalibus." This is a sexual 

 distinction which 1 notice in a species I found very commonly 

 and which I think I have rightly assigned to M. invectitius, 

 Cand.
