punetato ; thorace disco pauciter punctulato ; elytris apice singu- 

 latim rotundatis, supra subtiliter subseriatim punctulatis ; antennis 

 plus minusve rufescentibus, articulis a tertio apice obscurioribus, 

 scapo obconico, cicatrice incompleta. Long. 7-11 lin. J § . 

 cJ . Antennis articulis 3°-5 um paulo incrassatis. 



Nagasaki and Hiogo, common. 



Very similar to M. Jlstulator (Germar) ; rather less robust, 

 more smoothly clothed with fine tawny-ochreous, rather silky, 

 tomen turn, and the punctuation scarcely visible to the naked eye. 

 The male, as in M. jlstulator , M. argentatus, and other allied 

 species, has the 3rd to 5th antennal joints distinctly thickened. 

 As the rim which limits the cicatrice of the scape is much ab- 

 breviated, the species would, according to Lacordaire's system, 

 belong to a different subfamily from Monoliammus ; and, in 

 fact, I should consider it to be the Orsidis sobrius of Pascoe, 

 if that author had mentioned the thickening of the 3rd to 5th 

 antennal joints in the male. It would violate natural affini- 

 ties too much, however, to separate it from M. Jlstulator and 

 allies. 



Monoliammus sejunctus, n. sp. 

 M. fraudatori quam maxime affinis ; differt antennarum scapo tu- 



mido, clavato, articulis 3°-5 um ( $ ) linearibus haud incrassatis ; 



tibiis anticis flexuosis, intermediis tuberculo magis acuto. Long. 



6-10 lin. rfS.

Very similar in form and clothing to M. fraudator \ the 

 sculpture is also similar, except that in the female the disk of 

 the thorax is more strongly punctured, and the vertex also 

 marked with similar punctures. In the male the punctuation 

 varies, being sometimes similar to that of the female, and at 

 other times like that of M. fraudator. Notwithstanding the 

 many points of structural difference (the simple 3rd to 5th an- 

 tennal joints, more clavate scape, flexuous anterior tibia?, &c), I 

 strongly suspect it to be only a variety of M. fraudator. The 

 tomentum is more silky, especially on the elytra, where it varies 

 by lighter and darker shades. 



This species may possibly be the Orsidis sobrius (Pascoe). 



Monoliammus degener } n. sp. 



M. parvus ; M. fistulatori forma similis, rufo-fuscus, tomen to griseo 

 et rufo-fusco variegatus ; thorace crebre punetato, fulvo-pubes- 

 cente, spina laterali brevi, sulco transversali basali unico; scu- 

 tello fulvo-pubescente; elytris passim punctulatis, apice singulatim 

 subacuminatis ; antennis rufo-fuscis, articulis basi pallidis ; scapi 

 cicatrice fere obsoleta. Long. 4^-5 lin. 



Nagasaki ; three examples.
