HYBOTINAE. 



1. Syndi/as nit Ida Loew. 



Eesembling the European S. niyripes hut larger, thorax shorter haired, and 

 leg-s darker and more strongly bristled. 



5 . Eyes touching- for a long distance above, but very narrowly separated 

 below, the antennae ; upper facets enlarged. Thorax shining black but pleurae 

 and margin of disc (humeri, notopleural and prescutellar depressions, postalar 

 calli and margin of scutellum) slightly brownish polliuose. Abdomen black 

 with a violet tinge, very elongate, slender, widest about middle. Pubescence 

 conspicuous on basal half, shorter towards tip, the hairs on first one or two 

 segments pale. Legs shining black, pubescent and strongly bristled. Front 

 tibiae with only apical bristles and these short ; mid tibiae with three widely 

 spaced antero-dorsal spinose bristles besides the apical ones of which one 

 beneath is very long ; hind femora and tibiae slender at base, much dilated 

 towards tip, the femora with a complete antero-ventral row of about twelve 

 strong spines and two strong antero-dorsal spines on apical half ; tibiae with 

 tliree antero-dorsal bristles, one near base, another at middle, the third at tip. 

 Basal joint of front tarsi with a pair of bristles above at tip, and a finer 

 antero-dorsal bristly hair at middle, clothed behind with fine pubescence like 

 that behind tibiae, antero-ventrally with shorter hairs mixed with short bristles 

 of which one at tip is more distinct ; second joint with a similar but shorter 

 and finer pair of bristly hairs at tip, otherwise much shorter haired; middle 

 tarsi very similar but basal joint with the antero-dorsal bristle at middle 

 stronger, the antero-ventral bristles and hairs less numerous, the pubescence 

 behind less dense, while postero-ventrally about base there are 2-3 distinct 

 bristles; basal joint of hind tarsi considerably dilated with a pair of bristles 

 at tip above and a double row of distinct spines antero-ventrall}', otherwise 

 short-haired. Wings faintly yellowish-brown, the stigma slightly more so ; 

 discal vein after leaving discal cell slightly bowed downwards, then curved up 

 towards cubital, and only parallel with it for a very short distance at tip ; this 

 last section of discal vein one-third longer than penultimate section, and the 

 last section of next (tiftli) vein about three-quarters the length of its penulti- 

 mate section. 



Length about 3'75 mm.
