Habits, etc. 

 Glos6ina cali<jinea, which, from the data printed above, would appear to 

 be prevalent in parts of Southern Nigeria in the month of May, is evidently 

 prone to attack travellers in canoes. This has been observed both by 

 Mr. Garden and Dr. Lamborn, the former of whom, with reference to the 

 specimens taken by him in a canoe on a creek between Agbabu and Akiti- 

 pupu, on May 17 and 19, 1909, contributes the interesting note that the 

 flies " attacked during heavy rain " ; Mr. Garden also states that at the spot 

 at which the flies were encountered there was '^ dense cover,'"' consistino- of 

 " long grass and water-plants."" One of Dr. Lamborn's specimens (a male, 

 taken on the Oni River, on May 9, 1910) bears the following field-note : — ■ 

 " As I was going up river in a canoe at 3.0 p.m., this insect bit me on the 

 arm, and became so distended with my blood that it was unable to fly 

 away." A female in the possession of the Entomological Research Com- 

 mittee, taken by the same collector on the same river and date, bears the 

 label: — ^^ From European's back and distended with his blood, while 

 canoeing up river." A male and female from Dr. Lamborn, caught on 

 May 1, 1910, are labelled as being '' off European's clothes, while journeying 

 lip river in a canoe " ; and the remaining specimens of this species received 

 from the same source by the Entomological Research Committee are also 

 stated to have been caught on a European's clothes. 



Affinities and Distinctive Characters. 

 Among the group of species with dark hind tarsi constituted by Glossinct 

 palpaliti, Rob.-Desv., G. iKillicera^ Bigot, G. caliginea, Austen, and G. taclt- 

 inoides^ Westw., the new^ species can only be confused with the two first 

 mentioned. Care is necessary at the outset in order to distinguish 

 G. calujinea from G. palpalis, but the very real differences between the 

 two species have been pointed out in the course of the foregoing description. 

 The darker hue and usually larger size of G. caliginea, combined with 

 the characters supplied by the third joint of the antennoe (dusky colora- 

 tion, stouter shape, less prominent distal extremity, and especially the 

 absence of a conspicuous fringe of pale hair on the anterior and posterior 

 edges — see figs. 1 and 3), will suffice to differentiate the new species from 

 G. pallkera.
