•which is deeply notched. Elytra broader than the thorax, 

 somewhat strongly punctured, the punctures arranged in 

 irregular longitudinal strife ; apex of elytra broadly edged 

 with rufo-fulvous. 



Genus Argopus, Fisch. 

 Ent. Russ. ii. 184. 

 Argopus clypeatus. 



Hemisphfericus, rufo-testaceus, nitidus, antennis (basi 

 excepta), tibiis tarsisque nigris ; clypeo rugoso, apice bi- 

 furcato, lobis concavis, basi creta transversa, elevata, mar- 

 ginatis.

Very closely allied to A. nigritarsis, Gebl., and possibly 

 only a local form of that species, but tliQ character sepa- 

 rating it, although slight, is so constant in all the specimens 

 examined, that 1 have not hesitated to regard it as dis- 

 tinct ; the chief differential character resides in the clypeus. 

 In A. clypeatus the lobes of the bifurcation are deeply ex- 

 cavated, and separated from the face by an irregular trans- 

 verse ridge ; in A. nigritarsis this ridge is absent, and the 

 lobes themselves are very slightly concave. All other 

 characters are similar in both species. The present insect 

 is more than a third larger than A. nigritarsis. 



Argojjus orientalis. 



Subhemisphrericus, fulvus, nitidus, oculis antennisque 

 (his basi exceptis) nigris; thorace tenuiter, basi magis for- 

 titer, punctato ; elytris subfortiter punctatis, punctis sub- 

 striatim dispositis.

Hah. — Nagasaki. 



Head smooth, impunctate, encarp^e slightly oblique, 

 transverse, subquadrate, nearly contiguous; carina broad, 

 smooth; antennaj slender, entirely filiform, second and 

 third joints short, nearly equal, fourth and following joints 

 equal, each distinctly longer than the third ; lower portion 

 of clj^eus depressed, bilobed. Thorax more than twice 

 as broad as long, sides rounded and obliquely converging 

 from base to apex, anterior angles slightly but distinctly 

 produced, obtuse ; basal margin slightly bisinuate on either .
