228 Mr. 0. Thomas on 



Antennoi reddish brown; tliird segment broadly triangulav 

 at the base. 



Front uniformly wide, ab jufc one-sixth the breadth of the 

 head. Frontal callus black, tumid and very sliiiiy, consisting 

 of two separate parts — namely, a large trapezium completely 

 filling the space above the base of the antennse, and a smaller 

 somewlnit oval patch higher up. Ocelli large and very 

 prominent. Fi/es quite bare. 



Scutum and scutellum (denuded) dark. 



Legs reddisli brown, tibise and tarsi of first pair black. 

 Spurs on hind tibige small, reddish brown. 



Wings hyaline, with a long light-brown spot at the distal 

 end of the first longitudinal vein. Halteres dark brown. 



Abdomen very distinctly cross-banded — the after edge of 

 every segment being lighib brown ; the rest of the segment 

 being purplish brown in the case of the first two segments, 

 blackish brown in the case of the other segments. 



This species is very similar to S. alcocki in size and 

 general appearance. It can be distinguished from the latter, 

 however, by having no angle on the third segment of the 

 antennge. The colour of tiie legs is different and the spines 

 on the hind tibiee are not so distinct. The abdomen in this 

 species is darker in colour and more distinctly banded.

(Published by permission of the Trustees of the British Museum,) 



Nasua candace, sp. n. 



Allied to N. dorsalis, but the black dorsal line scarcely 

 defined. 



Size about as in N. nasua, though the teeth are smaller. 

 General colour above tawny ochraccous, a median darker 

 area, 2-3 in. in breadth, extending from the nape to the 

 base of the tail, but not forming a sharply defined black 

 dorsal line as in dorsalis. Along this area the hairs are 

 cream-buff basally, with tawny or ociiraceous tips and black 

 subterminal rings. Under surface brown, the tips of the 

 hairs buffy, throat and chest cream-buft'. Muzzle brown. 

 Ears thickly hairy, blackish with white edges. Forearms 

 pale buffy to the metacarpus ; digits dark brown. Hind 

 iimbs smoky brown^ some of the hairs, especially on the 

 metatarsus, pale buffy. Tail heavily haired, completely 

 ringed with black and pale buffy, about 7-8 rings present.
