Subgroup ]i. Elytral sculpture consisting of irregular fovese and subcosti- 

 forni interstices, divided into elongate, flattened elevations. 



21(22). Outline of elytra in the female much narrowed to apex. (S. noctisSl. 



22(21). Not as in <S. noctis. 



23(26). Elytra convex. 



24(25). Elevations on the second and fourth interstices not much 



fewer than on the other interstices S. convexus SI. 



25(24). Elevations on the second and fourth noticeably fewer than 



on the other interstices S. Spenceri Ferg., var.

(J. Large, elongate, subparallel. Black; densely clothed with 

 brownish, and with light yellow sette; ventral vitta light yellow. 



Head convex. Rostrum broad, dorsal surface broad; external 

 ridges prominent, thick, not extending up head; median carina 

 appearing as a narrow hievigate line, widening out in front, feebly 

 raised. Eyes ovate. Pi'othorax (7 x 8mm.) rather strongly dila- 

 tate in front of middle; apex gently rounded above, with definite 

 but rather small ocular lobes; granules depressed, especially in 

 the centre. Sides with granules obsolete except above, and ob- 

 solescent in front. Elytra(16 x 9 '5 mm.) robust, base emarginate, 

 humeri noduliform; punctures shallow, in regular rows, subtended 

 by small granules; interstices tuberculate; second with one or 

 two; third and fourth each with a continuous row of small 

 tubercles, rounded at base, rather larger and conical on or about 

 declivity, about twenty-five in each row, third interstices approx- 

 imated on declivity; fourth without tubercles; sixth with a 

 continuous row of thirteen, similar to row on fifth interstice. 

 Beneath, rather rugosely punctured ; apical ventral segment 

 grooved in the middle, with the oblique impressions rather in- 

 definite. Anterior femora ridged beneath. 



9. Shorter than ^, with the prothorax less dilatate, and more 

 rounded; elytra shorter, with the row of tubercles broken in the 

 middle, presenting the appearance of a badly set fracture. 

 Tubercle-index: 1, 22, 0, 21, 12.
