132 MARTIN JACOBY 



Head broad , impunctate , black , shining , frontal elevations 

 small and flat, labrum and palpi more or less fulvous, antennae 

 extending to the middle of the elytra, black, the lower seven 

 joints flavous, basal joint not much thickened, moderately long, 

 second scarcely shorter than the third joint, the others slightly 

 more elongate , thorax nearly three times broader than long , 

 the sides with a narrow margin, the anterior angles obliquely 

 thickened , posterior margin with a rather broadly produced 

 median lobe, the surface rather convex, black, shining, closely 

 and finely punctured, elytra convex, more strongly punctured 

 than the thorax, the punctures irregularly placed at the inner 

 disc, mixed with some smaller punctures, the sides with four 

 rows of regularly placed punctures, the interstices at the same 

 place, excepting the outer broader one, scarcely raised, legs dark 

 piceous or nearly black, as well as the underside, tibiae dilated 

 at the apex, longitudinally chanelled, breast and abdomen closely 

 punctured, prosternum subquadrate, broad, but slightly narrowed 

 at the middle. 



This , and several other species , at present placed in Sphae- 

 roderma will have to be probably placed in another genus on 

 account of the broad prosternum, which will also assist better 

 in the determination of the many variable and closely allied 

 Eastern forms ; the present insect seems closely allied to S. atra, 

 Jac. from Japan but differs in having the lower seven joints of 

 the antennae fulvous and in the partly irregular, partly regular 

 punctuation of the elytra. S. nigrita, Jac. is larger and has dif- 

 ferently sculptured elytra. 



9. Argopistes fulvoplagiatus, sp. n. — Fulvous, the antennae 

 and legs paler, thorax extremely finely and closely punctured, 

 elytra finely punctate-striate , the interstices finely and closely 

 punctured, piceous or black, a round spot at the middle, and 

 the apex of each elytron, fulvous. 



Length 1 1 / 2 line. 



Of strongly rounded and convex shape, the head impunctate, 

 the eyes occupying the entire sides, the space dividing them 

 very narrow with a short groove at the middle, lower portion
