102 DESCRIPTION OF GLOSSINA LONGIPENNIS. 



Thurax. — Clcjthed with grayish dust, but when denuded some- 

 times appearing reddish on median area of dorsum ; the two 

 dark brown spots in front of the suture slightly further apart 

 than the two behind it ; an additional pair of fainter and some- 

 what more reddish-broAvn oval spots usually visible on the feuture 

 itself, one on each side of the ad-median stripes, and between 

 them and the spots already mentioned ; in addition to these 

 marks there is usually a faint trace of a longitudinal stripe on 

 each side (representing the inner arm of the curved stripe, as 

 described for Gl. paljpaliii), between the two dark brown spots 

 and the spot on the suture ; indications of this stripe are usually 

 cpntined to the neighbourhood of the humeral callus and the hind 

 margin ; there is also usually a tiny reddish-brown fleck in front 

 of the suture, and between the two dark brown oval spots on 

 each side; humeral callus with only a faint trace of a brownish 

 blotch on its upper portion, Scutellum pale brownish, the 

 margin and impressed median line buff.* 



Ahdomen.—Th.Q dark brown interrupted transverse bandsj pf 

 the type seen in Gl. morsitans, are here much reduced ..(see 

 Plate VII.); posterior angles of the third to the sixth segments 

 inclusive clothed with whitish-gray dust. 



Legs. — Buff, femora with faint dark patches on the outer 

 side, and middle femora with a brownish blotch on und^r side 

 near tip (as in Gl. fusca) ; only a very faint trace (often entirely 

 wanting) of a darker ring on the hind tibias near the base ; last 

 joint and tip of penultimate joint of middle tarsi infuscated ; last 

 two joints of hind tarsi black. Row of bristles at base of front 

 coxse ochraceous ; hair clothing front coxpe below golden-yellow. 



Wings. — Brownish ; veins pale tawny, with local infuscations, 

 as in Gl. fusca. Squamss not infuscated ; fringe pale yellow, 

 silky. Halteres yellowish-white. 



The type of Gl. longipenms, Corti, is a ^ in poor condition, 

 which has evidently been kept in spirit prior to being pinned. 

 The above description has, therefore, been prepared from a ^ 

 from Somaliland (Th- Greenfield), in the collection of the -British 

 Museum, and a ? from West Somaliland, 23-25. vi. 1895 (C. V. 



* In two specimens (one of which is the type of the species) out of the 

 seven examples of Gl. longipcnnis that I have been able to examine there 

 is possibly a second dorso-central bristle, but if so it is so small as to be 

 practically indistinguishable from the surrounding hairs ; in none of the 

 specimens can an intra-alar bristle be distingnished. ■ : ■
