Recently described by me from the Island of Fernando Po. 

 There is a single female from Chirinda Forest, x. 1 !)()."> \ G. A. K. 

 J/r7/-.v //i7//), which agrees well enough with the typ;?. The black 

 spot at the base of all the femora is present, as well as in the two 

 other species. 



103. Mallota pachymera, sp. n. 



c? $ Length of the body in the male 10 mm. ; in the female 

 13'5 mm. 



Easily recognised by the enormously thickened hind femora and 

 by the abdominal pattern ; notwithstanding the difference in the 

 size, I believe that the two specimens belong to the same species.

 sides of the face grey pollinose, and therefore there is a broad black 

 band in the middle ; antenna! tubercle prominent ; face hollowed 

 below the antennae and with a broad rounded tubercle ; lunula 

 yellow ; eves with no distinct spots, clothed with long and dense 

 grey hair ; eyes of the male approximated on the middle of the 

 irons, but not touching; antennae black, the basal joints reddish, 

 the third ovate, twice as long as the two others, with a bare, dark 

 yellowish arista. Back of the thorax grey, not striped, clothed 

 with rather long greyish hair, longer on the pleurae ; scutellum 

 yellow, with long hair. Squamula) lurid, with a grey fringe ; 

 halteres whitish. Abdomen shining black, clothed with rather 

 long grey hair, shorter in the female, black at the hind border of 

 the segments ; the first segment is yellowish-grey with a basal 

 black spot below the scutellum; second with two indistinct and 

 narrow yellow spots on the sides, forming an interrupted band ;
