Type c? fr m Busiku, British East Africa, 5. ix. 1911 (E. J. 

 Stordy). This species, which has nothing to do with the Indian 

 genus Dideoides, Brunetti (1908), is a very important addition to 

 the genus Asarcina. 



Genus 5. SYEPHUS, Fulricius (1775). 



The rather numerous species in the collection before me can be 

 distinguished as follows : 



1 (16) Eyes hairy ; postocular border fringed along 



its whole contour with long and deuse 



hairs; antennas wholly black, the third 



joint elongate and rather pointed at the 



tip ; face always with a black spot or 



stripe in the middle. 

 L> (5) Pterostigma entirely yellow, not blackened 



at base ; face distinctly yellow, the dust 



not hiding the ground-colour ; peristoina 



rather broad and yellow. 



3 (4) Jowls with a black stripe running from the 



lower corner of eye to the upper edge of 

 the buccal cavity ; abdomen with four 

 white bauds, which do not reach the 

 eides ; third longitudinal vein straight . . w/w;/s.>-, Wied.* 



4 (3) Jowls wholly yellow, without black stripe ; 



abdomen with three yellow bands reach- 

 ing the sides, the first widely interrupted 

 in the middle ; third vein sinuous, as in 

 Lasioplithicus ; abdomen very short, 

 black pilose except at base euttenfatus, sp. n.
