40 MFw G. A. K, MARSHALL ON COLEOPTEEA [Jan. 19, 



shallow transverse impression behind apex, closely set with low 

 rounded tubercles, leaving a narrow but deep central furrow 

 containing no carina ; tubercles bare, shiny, each with a short 

 depressed seta, the interstices with dense brown scaling. Elytra 

 oblongo-ovate, narrower in (S , shoulders sloping, sides slightly 

 rounded, broadest about middle, apical processes (in $ only) 

 normally short, blunt and porrect, but variable and sometimes 

 entirely absent. Upper surface with shallow sulci containing 

 rows of ill-defined punctures separated by small granules ; the 

 intervals all closely and evenly granulate, 3, 5, and 7 being usually 

 slightly more prominent than the others, but in some examples 

 this is scarcely noticeable ; in interval 3 with a small tubercular 

 prominence at the top of the declivity, which is variable in size 

 and sometimes absent ; apices of granules bare, each with a 

 depressed seta, interspaces with fairly dense small brown scaling. 

 Legs distinctly thicker in S than in 5 , with sparse brown scaling ; 

 posterior tarsi with the 3rd joint a little broader than the others, 

 2nd and 3rd subequal in length, 1st rather longer.

Type in the Stockholm Museum. 



I can detect no difference whatever between the types of 

 costaius and bituberculatus. H. punctirostris appears to differ only 

 in its more even elytral intervals and in the absence of the apical 

 processes in the $ . These characters are, however, certainly 

 variable, and I have seen several intermediate examples which 

 render it impossible to regard the two forms as specifically 

 distinct. 



Father O'Neil writes of this species that it is common at 

 "Uitenhage and Grahamstown throughout the year, being gene- 

 rally found under stones on rich soil, but sometimes under dead 

 leaves and humus. 



23. H. angustus, sp. nov. (Plate I. fig. 5.) 



Long. 11-12-1-, lat. 4-5 mm. 



Head convex, rugosely punctured, and with sparse depressed 

 pale setse, forehead not flattened, but plicate and with a deep 

 impression just above each eye ; anteocular furrows almost 

 obsolete. Rostrum a little shorter than head and prothorax, 

 with a transverse dorsal incision at base, distinctly curved, rather 

 thicker in $ . UjDper surface convex, with five narrow smooth 

 carinse, the central one being a little higher than the others, the 

 intervening sulci closely punctured and clothed with brown setse ; 

 lateral sulci deep, meeting at base, about equal in length ; scrobes 

 entirely lateral, subparallel with the sulci ; inferior basal furrow 

 deep. Antennas with fine whitish pubescence ; scape just reaching 

 eye ; the two basal joints of funicle subequal. Prothorax as 

 long as broad in S , slightly ti'ansverse in 5 , apex narrower 

 than base, with a shallow constriction just behind apex, dorsal
