Table of Suhfamilies. 



1. Proefurca comparatively loug, 2nd. loufjitu- 



dinal vein originating in knee-shaped form 

 from it, approximately opposite anterior 

 cross-vein (at most Iialf-way between 

 origin of prasfurca and the cross-vein, and 

 this only in some species o1 Argyr amoeba);* 

 antenna) widely separated at base ; frous 



in J nearly as wide as in $ Anthracin^. p. 176. 



Prtefurca comparatively short, 2nd vein ori- 

 ginating acutely (not in knee-shaped form), 

 always much nearer origin of prjefurca 

 than of anterior cross-vein ; antenna; 

 nearly always approximate at base ; eyes 

 in (5 normally contiguous or nearly so, 

 sometimes distinctly separated, but irons 

 always much narrower than in $ f 



2. Abdomen, hind legs, and antennoe conspi- 



cuously long; eyes normally contiguous 

 in both sexes; only three posterior cells; 

 thorax not unusually humped ; occiput 



concave ; bare species Systropin^, p. 289. 



Abdomen, legs, and antennae (taken together) 

 not conspicuously long; eyes normally 

 contiguous in J , wide apart in $ ; pos- 

 terior cells usually four; thorax often 

 considerably humped ; occiput generally 

 inflated ; bare, moderately or densely 

 pubescent species ;]. 



3. Abdomen rounded or oblong ; often f uvry ; 



antennte never conspicuously long 4. 



Abdomen more or less cylindrical, bare or 

 with bristly hairs ; antennae very long, 

 especially 1st joint ; proboscis nearly 

 always long. (Thorax more or less 

 bumped, generally with conspicuous 

 bristles; abdomen drooping; prothorax 

 sometimes forming a shield ; body often 

 with scaly pubescence) Toxophortn^^, p. 286. 



4. Abdomen short and rounded; thorax and 



abdomen generally with dense furry pu- 

 bescence ; proboscis long and with small 

 labella; t thorax generally arched ; 2nd 

 longitudinal vein never with a strong loop 

 near tip ; head generally narrower than 



thorax Eojibyliin^, p. 259. 



Abdomen oblong, rather flattened, seldom 

 really furry ; proboscis generally short 

 and with larger labella; thorax oenerallv 



* At least two (European) exceptions are known, CalliMoma and Mulio. 

 t Some species of Usia have the ejes in tlie (^ widely sejjarated, but they 

 are easily recognised by their abort, ruunded bare abdomen. 

 \ Except in a few non-Oriental genera.
