DESCIUPTION OF GLOSSINA LONGIPALPIS. 91 



sexes, 3 millim. (H Ha.) ; width of front at vertex in (^ ^, in 

 9 between ^ and ^ of total width of head measured acrosa 

 middle of eyes. 



Thorax olivae.eous-grmj , icith the umal dark-brown longitudinal 

 markings ; abdomen ochraceous-buff* with interrupted dark bands, 

 which stand out conspicuously from ground-colour, and leave hind 

 margins of segments only narrowly pale ; sides of front in <J 

 parallel, in 9 converging slightly towards vertex ; legs ochraceous- 

 buff, last two joints of front and middle tarsi with sharply defined 

 black tips as in Gl. moi-sitans. 



Very close to Gl. pallidipes, Austen, but distinguished at 

 at once by the black tips to the last two joints of the front and 

 middle tarsi. Eyes in ^ large and tumid, resembling the eyes 

 of Gl. pallidipes more than those of Gl. morsitans. Front of (J 

 not quite so narrow as that of <J pallidipes; frontal stripe 

 tawny, darker above, frontal margins and vertical triangle oli- 

 A'aceous-gray ; elongate dark-brown spot on each side of frontal 

 stripe below generally very conspicuous, as is also the narrow 

 dark-brown band connecting the bases of the vertical bristles. 



Dorsum of thorax with the brown markings described in the 

 case of Gl. palpalis fairly distinct. Scutellum buff, grey at the 

 base, with a strongly marked dark-brown triangular spot on 

 each side of the median line. 



Abdomen, with the usual interrupted dark-brown bands on 

 the third to the sixth segments inclusive, strongly mai'ked and 

 deep, precisely as in Gl. pallidipes, leaving the hind margins of 

 the segments only narrowly pale. 



Legs buff, the front femora strongly infuscated on the inner 

 side, and generally more or less infuscated on the outer side also. 

 Middle femora usually more or less infuscated on the outer and 

 inner side ; hind femora slightly infuscated on the outside 

 towards the distal extremity. Middle and hind femora often 

 with a strongly marked elongate black spot on the under side near 

 the end.
