the base of the apical fourth, becoming narrowed towards the apex, 

 but not to a sharp point ; the narrowed apex is keeled above and is 

 bordered latertlly by a deep depression, rounded on the outer side 

 and continued backwards to near the base of the keel ; the lateral 

 furrow is deep, moderately wide, and extends from the base to the 

 apex ; there are distinct, smooth furrows, with distinct, oblique 

 lateral branches on the base of the third, fourth and fifth segments. 



EXOTHECUS PULCHRIPENNIS, Sp. nOV. 



Ferruginous ; the antennae, hind tibiae and tarsi black ; the upper 

 and lower side of mesothorax tinged with black ; wings yellowish 

 hyaline, an irregular cloud extending from the apex of the costa 

 across the transverse basal to shortly below its middle, more narrowly 

 on the base of cubitus, irregularly, obliquely across the first discoidal 

 cellule, it being narrowed to a point, a smaller cloud in the second 

 discoidal, occupying the apex, narrowed in front, the apex with a 

 longer slope than the base ; a cloud round the apex of the wing, 

 irregularl}- dilated towai'ds the second cubital cellule, where it is 

 narrowed with a dilated part on its base in the middle ; the apex of 

 the hind wings, the cloud continued along the lower side of the 

 cubitus to near the middle of the wings, it becoming gradually wider 

 towards the base ; above it and reaching to the apex is an irregular 

 cloud. $ . 



Length 19 mm. ; terebra 22 mm. 



Cape Colony. Neighbourhood of Cape Town. 



Face rugosely punctured, the clypeus and a large space on either 

 side of it smooth. Smooth, shining ; the metanotum and base of 

 abdomen pilose. Area on second segment triangular, as long as its 

 width at the base, not very clearly defined at the apex, which does 

 not quite reach to the middle. Antennal scape about four times 

 longer than wide, as in E. flavofasciatus. Hypopygium short, not 

 projecting much beyond the apex of the last dorsal segment. 



ExOTHECUS FLAVICEPS, Sp. nOV. 



Black, the head yellow ; the pro- and mesothorax red ; the 

 anterior legs testaceous ; wings dark fuscous, iridescent, tinged with 

 violaceous, a yellowish- hyaline cloud on either side of the second 

 transverse cubital nervure, extending shortly beyond the cubitus, 

 and broadest on the outer side. 2 . 



Length 16 mm. ; terebra 10 mm.
