﻿DESCRIPTIONS OF NEW SPECIES — PART I. 365 



Female. Palpi with all the segments usually slightly shorter than those of 

 the male.

North Eastern Rhodesia : the type and other examples were taken by 

 Mr. S. A. Neave in the following localities : — Mid Luang wa River, 30. viii. 

 1910, 2 $ J ' 1 Lower Luangwa River, 5. ix. 1910, 1 $ ; on the road between 

 % Petauke and Chutika's Luangwa Valley, 16. ix. 1910, 2 c? 3 ; Niamadzi River, 

 19 and 21. vii. 1910, 3 c? S '•> junction of Mpamadzi and Luangwa, 24. viii. 1910, 

 2J(J,1Q; Mpamadzi River, Luangwa Valley, 23. viii. 1910, 1 (J,l Q. 



Nyasaland : Chitala stream, 10 miles west of Domira Bay, 22-28. x. 1910, 

 1 Q (S. A. Neave) ; near Lake Malombe, Upper Shire River, 4. viii. 1911, 

 1 rf ; 9. viii. 1 1, 1 Q ; 29. ix. 11, 1 Q (R. New stead and Dr. J. B. Daveg, 

 Sleeping Sickness Commission.) 



The examples herein recorded from Nyasaland by Dr. Davey and myself were 

 all taken inside our tents during the day-time. Had these insects been more 

 conspicuous other examples could no doubt have been secured ; but pressure of 

 other official work prevented us from making a more thorough search for them. 

 Their presence at night was indicated by the feeble mosquito-like sound which 

 they produced when hovering around one's face under the mosquito curtain ; but 

 their visits to our camp at night were markedly few during the months of July 

 to September, inclusive, so that at this season they evidently occur in small 

 numbers. 



Phlebotomus antennatus, sp. nov. 



Length, 2*35 mm. ; wing 1*4 mm. 



This species may be distinguished at once by the short stout form of the 

 antennal segments, of which the third to the thirteenth, inclusive, are much more 

 bead-like than those of any other species which has hitherto been described. 

 Furthermore, it may be distinguished from P. minutus var. africanus, by its 

 shorter and stouter legs. 



Female. Colour and arrangement of the hairs on the head, thorax and 

 abdomen somewhat doubtful, owing to the rubbed condition of the specimen, but 

 their arrangement appears to be the same as in P. minutus. 



Antennae (fig. 2 d, e) with all the segments, unusually short and stout ; the 

 third scarcely one-third longer than the fourth ; the thirteenth segment only 

 very slightly longer than the succeeding one ; the paired and geniculated spines 

 are present on the third to the fifteenth segments, inclusive ; the hirsute glands, 

 seen so clearly in other species, not traceable, and if present, they are apparently 

 quite rudimentary. The long hairs on all of the segments decidedly scattered 

 and not so much confined to the proximal portions as is usually the case. 

 Palpi : second to fourth segments, inclusive, like those of P. minutus, including 

 also the compound groups of spines upon the proximal portion of the third
