260 MR. G. A. K. MARSHALL ON THE | Mar. 20, 



the third joint a Httle longer than the first, subtei'nainal joints 

 elongate. Prothorax strongly transverse, truncate at base and 

 ajiex, the latter nari'ower, sides slig'htly rounded (but sometimes 

 almost straight in the posterior half), broadest abovit middle and 

 with a shallow constriction close to apex ; upper surface convex, 

 closely set with small gi-aniiles and without impressions ; colour 

 piceous, with fine gi'ey scaling, which is sparse dorsally and denser 

 on the sides. Elytra broadly ovate in the S , subglobose in the 

 2 , subtruncate at base; sides very strongly rounded in the § ,less 

 so in the J ? broadest about middle : upper surface convex, with 

 deep striae containing shallow punctures separated by small 

 granules ; the intervals coiivex, smooth, cox'iaceous, with a few 

 small granules on the declivity ; in the 5 there are usually irre- 

 gular rows of gi\anules on intervals 7 and 8, which may often be 

 seen from above in the form of a lateral crenulation ; colour 

 piceous, with fine grey scaling, which in the c? forms the following 

 markings : a dense irregular lateral stripe, a sublunidate trans- 

 vei'se band above declivitj', some small irregular spots on the disk, 

 and occasionally a well-defined sutural stripe (var. chictns Boh.) ; 

 in the $ the scaling is more evenly distributed and these markings 

 are only vaguely indicated, but the sutural stripe is never present. 

 Leys moderate, the anterior tibiae straight externally and slighth' 

 sinuate internally in $ , in S broader, curved externally near 

 apex and sti-ongly sinuate internally. 



Type $ in the Stockholm Museum. Types of ductus and 

 varius also in the same Museum. 



Cape Colony : Uitenhage and Port Alfred {Father O'Neil), 

 Kowie and Grahamstown [S. A. Mus.]. Pondoland : Poit St. 

 John {G. Shortridge). 



After a very careful examination of Boheman's types of cinctiis 

 and varius together with a fui-ther series of ten specimens, I can 

 find no reliable specific character by which the two forms may be 

 difi"erentiated! Both the thorax and elytra vary somewhat in 

 their outline, as also does the curvature of the rostral carinas, but 

 these characters all vary independently of each other, and the 

 variations show such gradations as to I'ender them useless as 

 specific characters. That these two forms I'epresent the male sex 

 of iSparrman's puUvs there can, I think, be but little doubt. Of 

 the latter form I have seen eleven examples, and these exhibit 

 variations in the shape of the thorax and elytra, similar to those 

 observable in the males.
