734 MR. M. JACOBY ON THE [NoV. 3, 



of the posterior tibiae as long as the two following joints together, 

 claw-joint distinctly swollen. 



Yuyama, Hitoyoshi. 



There are three specimens of an entirely fulvous colour, and three 

 in which the thorax only is of this shade. The species is closely 

 allied to H. beavani, Baly, from India; but in the latter the elytra 

 are of a metallic blue or green colour, and the head shows no traces 

 of strigae. 



Genus Argoptjs, Fisher. 



Argopus nigripennis, sp. nov. 



Black ; lower part of head fulvous ; thorax narrowed in front, 

 closely punctured ; elytra irregularly and closely punctate. 



Length 2 lines. 



Head impunctate at the vertex ; frontal tubercles divided and 

 bounded behind by a moderately deep transverse groove; lower part 

 of face rugosely punctured, fulvous. Antennae more than half the 

 length of the body, black, the apices of the first three joints fulvous, 

 second and third joints equal, one half shorter than the fourth. 

 Thorax narrowed in front, the sides but little rounded, surface 

 rather closely and irregularly punctured, the basal margin impressed 

 at each side with a row of deeper punctures. Scutellum fulvous. 

 Elytra not more strongly punctured tliau the thorax, the punctuation 

 irregular and only here and there arranged in striae, the ])unctuation 

 absent at the anterior portion near the lateral margin, the latter 

 impressed with a deep row of punctures. Underside and legs black, 

 the anterior coxae and the apex of the abdomen fulvous. 



Shinionosuwa. 



I am somewhat doubtful whether the single specimen before me 

 represents really a new or a variety of one or other species of 

 Argopus, perhaps A. nigritarsis. The thorax of that species is, 

 however, more transverse and less narrowed in front, and the 

 general shape of the insect more rounded ; the black colour of the 

 present species is unique amongst its allies. 



Argoptjs clarki, sp. nov. 



Ovate, convex, pale fulvous ; antennae (the three basal joints 

 excepted) and legs black ; thorax very finely punctured ; elytra 

 strongly subgeminate punctate-striate. 



Length 2 lines. 



Head impunctate, the frontal tubercles flattened and broad. 

 Antennae half the length of the body, black ; the three basal joints 

 fulvous, second and third joints short and equal. Thorax at least 

 three times as broad as long, the sides rather rounded, the anterior 

 angles oblique ; surface rather closely covered with fine and larger 

 punctures, a row of the latter accompanying the posterior margin. 

 Elytra strongly punctate-striate, the punctures arranged in irregular 

 and rather remotely placed double lines, the space near the lateral 

 margins impunctate. Underside fulvous. Legs black. 



Miyanoshita.
