252 MR. M. JACOBY ON PHYTOPHAGOUS COIiEOPTERA [Mar. 6, 



very finely punctured, with the anterior fourth portion black. 

 Three specimens are before me, which do not differ from each 

 other. 



Sph^eroderma mashonana, sp. n. 



Subglobulose, reddish fulvous, the apical joints of the antenna 

 and the tibiae and tarsi black ; thorax extremely minutely and rather 

 closely punctured ; elytra punctured like the thorax, the punctures 

 irregularly placed. 



Length 4 millim. 



Head impunctate, the clypeus deflexed anteriorly, with a dis- 

 tinct central longitudinal carina ; eyes very large ; the antenna? 

 extending to the base of the thorax only, flavous, the terminal five 

 or six joints fuscous, subtriangularly dilated, the last strongly 

 pointed ; thorax nearly three times broader than long, the sides 

 feebly rounded, with a very narrow margin, the anterior angles 

 rather thickened and obtusely rounded, the posterior margin 

 broadly produced at the middle, sinuate at the sides, the surface 

 closely and very finely punctured ; scutellum triangular, pointed ; 

 elytra subglobular, evenly and very strongly convex, the shoulders 

 rounded and slightly prominent, the punctures not or scarcely 

 larger than those of the thorax, irregularly distributed and here 

 and there arranged in lines, those near the lateral margins nearly 

 obsolete ; elytral epipleura? extremely broad and concave ; legs and 

 the underside fulvous, the coxa? and the tibia? and tarsi blackish ; 

 presternum elongate, constricted at the middle, strongly punctured. 



Hah. Salisbury, Mashonaland, May and October (G, Marshall). 



Eesembling somewhat in size and shape the European Argopus 

 ahrensi Gebl., but still more convex, the antenna? very short and 

 dilated, and the punctuation of its upper surface very fine. The 

 present species is the largest of the genus known to me from 

 Africa. 



Bl/EPHARJDA REGULARIS, sp. U. 



Subquadrate ovate, fulvous ; head and thorax fiavous, the latter 

 minutely punctured ; elytra strongly punctate-striate, the inter- 

 stices costate at the sides, with numerous closely placed flavous 

 spots, the lateral margins broadly flavous, spotted with fulvous. 



Length 5| millim. 



Head very sparingly and finely punctured, flavous, with a deep 

 semicircular groove in front of the eyes ; clypeus broad and flat ; 

 antenna? not extending to the middle of the elytra, fulvous, the 

 terminal six joints short and thick ; thorax more than twice as 

 broad as long, narrowed anteriorly, the sides nearly straight, the 

 anterior angles thickened, the surface extremely finely punctured, 

 only visible under a strong lens, with two small round depressions 

 near the lateral margins ; elytra with ten rows of deep and closely 

 placed punctures, the subsutural one short, the punctures fulvous, 

 the interstices varied at regular intervals with fulvous and flavous
