Ceylon: Colombo, 1910 (0. S. Wickwar). 



Collected and presented to the British Museum by 

 Mr. O. S. Wickwar, after whom the species is named. 



Through the courtesy of Colonel C. G. Nurse I have beeu 

 able to examine the type of Nomada priscilla from North 

 India, to which species N. wickwari is nearly related. 

 Nurse's species, however, is smaller and more slender, with 

 joints 3 and 4 of the antennae equal ; the neuration, too, is 

 different from that of the present species. 



Nomada antennata, sp. n. 



$ . Nigra, thorace ferrugineo ; segmento secundo abdominis maculis 

 duabus flavis ; capite thoraceque punctatis, abdoinine nitido ; 

 antennis uigris, elongatis ; alis subfuscis. 

 Long. 6 mm. 



? . Black ; thorax and anterior tarsi beneath ferruginous ; 

 two ovate basi-lateral spots on tergite 2 and two small 

 indistinct marks on tergite 5 pale yellow. Head and thorax

Ceylon : Kandy (O. S. Wickwar). 



Resembles N. wickwari in general facies, but is at once 

 distinguished in having long black antennae, with joints 3 

 and 4 subequal, and the head and legs black. 



Five species of Nomada are now known from widely 

 separated localities in the ^Ethiopian Region ; no specimens 

 appear to have been received from Central Africa as yet. 



The following key may help to separate the ^Ethiopian 

 forms :—
