distinct raised lines on the keel, which start from the base 

 and anteriorly join about the middle (these lines in H. rep- 

 pensis are indistinct and longer, and do not join in front) ; 

 the metasternum, punctures clear and distinct and larger than 

 those of H. reppensis ; the antennae, anterior and intermediate 

 legs pale red ; hinder tibise pale, with the femora black. 

 Hab. Nagasaki. 



Aspidimerus orhtculus, Gyllenhal. 



Aspidtmerus orhiculus, Gyll. Sclion. Syst. Ins. i. p. 205 (1808) ; Crot. 

 Revis. Coc. p. 203 (1874) {Cryiitogonus) ; Weise, Best. Tab. ii. 

 p. 63 (1885). 



Schonherr, a contemporary of Gyllenhal, seems to have 

 considered that this species belonged to Gyllenhal ; I have 

 not seen the original description. 



Hah. Nagasaki and South Japan generally. Common. 



Platynaspis Lewisiij Crotch. 

 Platynaspis Lewisii, Crot. Revis. Coc. p. 198 (1874). 



The face of this species is sometimes wholly black and the 

 spaces between the dorsal spots yellow. I have two speci- 

 mens, both from high altitudes (Miyanoshita and Oyama in 

 Sagami), in which the elytra are black, with a small red spot 

 at the base on either side of the scutellum. Crotch omitted 

 to mention that he had seen Japanese specimens of this 

 species ; in the ' Revision ' he only refers to an example from 

 Shanghai. Weise states (Deutsche ent. Zeit. p. 413, 1892) 

 that Microrrhymhuft, Gerst. 187 'i , = Platynaspis, Redt. 1843. 



Hab. Tokio, Yokohama, and Kobe. 



Amida, gen. nov. 



Type Scymnus tricolor, Har. 



This new generic name I propose for an insect which 

 measures 4-4^ millim. and has most of its characters similar 

 to those of Scymnus. The eyes, however, are very different, 

 being large, more finely faceted, and the inner edges are 

 straight and parallel to each other, leaving a bilateral facial 

 space (very noticeable) between them ; the antennae long and 

 slender, 11 -jointed, first two large, bulbiform, and distinctly 

 separate ; terminal three joints form an elongate club ; the 

 terminal abdominal segment is very narrow and transverse ; 

 the tibias are swollen on the outer edge, the claws with a 

 robust inner process.
