Ilah. Gold Coast, Aburi (JF. II. Patterson), 



Described from one male specimen. There are also in the Museum 

 two similarly coloured females, with the head in profile distinctly" helmet- 

 shai^ed — one from Durban, Natal {F. Leigh ), and the other from Mount 

 Mlanje. Nyasaland (^. A. Neave). They probably represent another 

 species, but I refrain from naming them in the absence of a male. 



Phea Distant. 



The tj'pe of this genus, P. am2)lijicata Dist., is represented in the 

 collection by two females in damaged condition, and neither of them 

 agrees with the generic description or the figm*es. The description says 

 that the antennae are " short, robust," and are so figured, but the speci- 

 mens have the first joint long and the second jomt complex, somewhat 

 as in Otiocerus. The figures of the head show a very large subantennal 

 plate, but the specimen possesses none. I shall look upon the insect 

 marked type as the correct type, and ignore the description and the 

 figures of the head. The specific description founded upon colour 

 agrees with the dorsal view of the insect as figured and with the 

 type. The second joint of the antennae is composed of two j^arts : 

 a short thick portion on which the arista is situated and a ribbon-hke 

 appendage. 



P. atromaculata Dist. 



This species is represented by one male specimen which is congeneric 

 with P. am^lificata Dist., but the second joint of the antennae consists 

 of three parts : a small shoi't process on which the arista is situated and 

 two more or less ribbon-like appendages, one much longer than the other. 



P. pictipennis Dist. 



This is represented by one female specimen, which lias well- 

 developed shoulder keels and subantennal plates, and is a Mysidioides 

 Mats. {■=I^eocyclometopum Muir). 



Aecha Distant. 



This genus differs slightly in the shape of the head from Seronax 

 Kirk., but otherwise is the same, and I consider them to be synonymous. 

 Arch a has the apical joint of the labium longer than usual in the 

 DerhidaCy nevei-theless, in my opinion, it cannot be excluded from that 

 famil}'.
