438 Mr. W. L. Distant's first report on the 



Muls., but differs by the colour of the 1st joint of the 

 antennae and by the punctuation of the lateral margins of 

 the pronotum. I possess a specimen of P. adspersus 

 from the Amur, and find the above differences to be valid 

 and distinct, thus affording further evidence to the expe- 

 rience which I have already acquired, and showing that, 

 as a rule, Rhynchota from the Amur are distinct, though 

 closely allied to those of Japan. The females are con- 

 siderably larger and generally darker in colour than the 

 males : the species altogether varies towards melanism, 

 and the series recently brought home by Mr. Lewis are 

 considerably darker than those he procured on his 

 previous journey. 



Mr. Lewis' localities are Nagasaki, Yokohama, Wada 

 toge. 



Dieuches dissimilis, n. s. 



Head and pronotum black ; lateral margins of pro- 

 notum (excluding extreme base and ajDex) luteous, casta- 

 neous before the lateral angles, which are black; antenna? 

 with the 1st and 2nd joints ochraceous, the 3rd and 4th 

 fuscous ; eyes dark fuscous ; scutellum black ; corium 

 luteous, apical margin and inner angle broadly castaneous, 

 with an irregular elongate black spot (widest anteriorly) 

 on apical claval margin, and two black costal spots 

 beyond centre ; membrane fuscous, paler at base and 

 apex ; body beneath black ; legs reddish ochraceous. 

 Head, pronotum, and scutellum coarsely but obsoletely 

 punctate, clavus with three longitudinal series of punc- 

 tures, corium with a distinct submarginal series of 

 punctures curved inwardly towards apex, and preceded by 

 a short discal series and an apical submarginal series. 

 Long. 5 mm. 



Hab. Ono, Hakodate. 



This species is rather aberrant to the generic character 

 of Dieuches, by having the anterior femora somewhat 

 incrassated. In general structure it is allied to D. 

 armipes, Fabr. 



Paradieuches, n. g. 



Allied to Dieuches (section D. armipes, Fabr.), but 

 with the anterior femora strongly incrassated and dis- 

 tinctly spined beneath near apex ; pronotum with the 

 anterior margins convex, transversely constricted a little 

 behind the middle, before which the anterior area is
