R. NEWSTEAD — ON THE CHARACTERISTICS OF GLOSSINA. 



" I notice that G. pallidipes prefers to bite low down, and that G. austeni 

 bites high up. The latter are considered specially deadly to cattle. All the 

 insects were caught in longitude 42° 48' between 0° 43' and 0° 55' N. latitude, 

 approximately. In May last year (1911) I saw the first small austeni in the 

 garden here, and when Dr. Chevallier came up later I told him about it and 

 said he ought to make a search, accordingly on his way up the river he did 

 so and got a specimen, in the meantime I got two also." 



I have nothing to add to Mr. FilleuTs communication regarding the bionomics 

 o£ G. austeni, though I have pleasure in stating that this species was dedicated, 

 by kind permission, to Mr. E. E. Austen of the British Museum, in recog- 

 nition of his great work in connection with these insects, and also as a token of 

 esteem and regard.

processes ; the proximal pair are highly chitinised, broad and somewhat lanceo- 

 late, with the upper edge coarsely and irregularly serrate, the proximal half 

 strongly curved ; the second pair of appendages or processes are extremely 

 narrow, especially the distal two-thirds, base slightly dilated and much more 

 highly chitinised than the rest, apices hidden beneath the next pair of processes ; 

 third pair very long and much narrower than the proximal pair, being also more 

 or less ribbon-like, with the distal portion decidedly narrower. Vesica (?;) with 

 two large dark-coloured chitinous sclerites. Inferior claspers (ic) normal.
