DESCEIPTION OF GLOSSINA FUSCIPES. 29 



r 

 From G. paUicera, Bigot (p. 35, Plate -III), the present species, 

 apart from being much darker, may at once be distinguished by 

 the dusky colour of and absence of long hair on the third joint of 

 its antennae. With G. tachinoides, Westw. (p. 39, Plate IV), 

 there is no possibility of confusion owing to the characteristic 

 abdominal markings of the former. 



Glossina fuscipes, Newst. 



Glossina fuscipes, Newstead, Annals of Tropical Medicine and Parasit- 

 ology, Series T. M., Vol. IV, No. 3, p. 375 (December 20, 1910). 



No specimens of this species, of which the type is at present 

 in the possession of the Liverpool School of Tropical Medicine, 

 have yet reached the British Museum (Natural History) ; the 

 following, however, is a verbatim transcript of the original 

 description. 



" This tsetse-fly may be readily distinguished from Gl. palpalis, 

 Rob.-Desv., by its much smaller size, by the uniformly inf uscated 

 or dusky legs, and the dusky-grey thorax. In size it resembles 

 G. tachinoides, West., but it is a relatively stouter built insect ; 

 and altogether it is most like a dwarfed specimen of Gl. imlpalis 

 with infuscated legs and a dusky thorax. The genital armature 

 resembles those of Gl. palpaUs and Gl. tachinoides in its general 

 form ; but the shape of the superior claspers and the inferior 

 claspers are markedly distinct from those of either of these 

 insects. 



" Length. — 7| mm. ; length of wing, 8 mm. 



^' MALE. — Head: frontal stripe yellowish brown, margins 

 dusky white ; ocellar triangle bufi", enclosing a very dark brown 

 spot. Antennae grey ; arista dark brown ventrally. Palpi smoky- 

 brown, with a paler median line. Proboscis with the bulb dark 

 castaneous. 



" Thorax with a median dark grey rectangular area extending 

 from the front to the scutellum, the sides of which are perfectly 

 straight and parallel, on either side of this grey area are two 

 greyish-black and somewhat triangular blotches, evidently rem- 

 nants of those found in other species of Glossina ; scutellum dark 

 grey, with a very faint pale grey median line, margins bufl" ; sides 

 of the lateral thoracic depressions dark brown or almost black ; 

 pleurae dark grey. 



" Abdomen resembling that of Gl. palpalis, but the bi-lateral
