HOPLOCEPHALA MACULOSA, Var. PUBERA, U. var. 



The genus Hoplocephala Macq. contains numerous kinds with all 

 kinds of facies in the S ; but almost uniformly ashy with rows of 

 triangular black spots on the depressed abdomen in the $ ; as shown 

 by sundry new sub-genera established by me. As a result of this the 

 determination of the $ $ is difficult ; and as for the S $ , especially in 

 the sub-genus Hoplocephala . strict., the varieties are not easy of 

 recognition. There appear to be species with naked eyes ; I have seen 

 one such case, a $ from Entebbe, Uganda. It might be mistaken for 

 H. maculosa, yet it is distinct owing to the genae with sparse and short 

 hairs, and the weak setae of the oblique row ; the median black spot 

 of the 3rd abdominal segment is replaced by 2 black parallel bands set 

 close to each other. On the ventral side, the presence is noticeable of 

 a long pilosity which starting from the posterior border of segment 3 

 and from the sides of segment 4, is directed towards the median line of 

 the latter and forms there an elongate tuft in front of the genitalia.

HOPLISA NOVICIA, U. sp. 



Similar to H. xantliocepliala Bez. and of the same size ; differs only 

 by the head. The latter seen in profile is broader than high ; the 

 peristome is almost half less wide ; the antennae are wholly black ; 

 the orbits are greyish blue, the genae whitish ashy, the median frontal 

 band and the medians orange yellow.
