364 Descriptive Catalogue [1896. 



Var. Ovampoa. 



Head and prothorax of A. cephalotes, tomentum white instead of 

 fulvous ; elytra more parallel, costate, intervals with a series of 

 punctures on the sixth interval, a very small faint white pubescent 

 subhumeral dot, and a supra-marginal outer band reaching frora 

 about the median part to the suture ; also a short juxta-scutellary 

 diagonal band on each side. 



This variety is a transitory form between A. limhata and A. cepha- 

 lotes. I have seen many well-preserved examples from the same 

 locality ; in all of them the smallness of the subhumeral patch was 

 constant, the costge of the elytra were more raised than in limhata 

 and slightly more than in cephalotes, but more shining than in the 

 last-named species ; the elytra are also more parallel than in cepha- 

 lotes, that is to say the anterior angle is less sloping. Length 

 25-28 mm. ; width 8-8^ mm. 



Hah. Ovampoland. 



Var. (Bq;uilatera, Klug, Peters' Eeise, n. Mosamb., 1862, p. 152, 

 pi. 8, fig. 6. 



Head and prothorax of A. cephalotes ; elytra still more parallel than 

 in ovampoa owing to the anterior angles being hardly rounded, very 

 plane, costate, with the costse moderately sharp, intervals punctured, 

 the punctures slightly setigerous, on each side a small elongato- 

 quadrate white pubescent patch situated a little above the median 

 part, and a narrow marginal white band reaching from below the 

 shoulder to the apex ; also a short basal juxta-scutellary diagonal 

 band on each side. Length 28-33 mm. ; width 8-9 mm. 



Although more closely allied to A. ovampoa than to limhata and 

 cephalotes, A. cBquilatera is easily distinguished by the position of the 

 dorsal white patch, which is about twice further from the base ; the 

 elytra are also more parallel. 



In one of my female examples from Mozambique, the punctures 

 of the intervals are much deeper, and the costae more raised than in 

 another from Mashunaland. 



Hah. Zambezia, Mozambique. 



Yar. torva. 



Head of A. ceplialotes, &c., but with the two transverse ridges much 

 more developed ; prothorax less narrowed behind, massive, hardly 

 depressed in the centre, but with a longitudinal narrow median 

 groove, seemingly hairless ; elytra parallel, with the shoulders 

 sloping, convex, punctato- striate, with the intervals broad, convex ; 

 the striae with setigerous punctures ; the hairs very short ; no dorsal 

 markings except the short juxta-scutellary diagonal pubescent band, 

 and also a narrow marginal white band reaching from below the 

 humeral part to the apex. Length 36 nnn. ; width ICH-Il mm.
