VENATIONAL VARIATION. 
The Forewing. 
Humeral Veinlet (hm).—The humeral veinlet varies greatly in strength. 
Its condition has some reference to the shape of the wing at the base; 
where the costa is deeply hollowed out, or the wing narrowed in some other 
way, as in Sabatinca calliarcha, S. chrysargyra (fig. 5), or S. barbarica, 
hm has almost disappeared. ; ' 
Subcostal Vein (Sc).—The upper fork (Sei) is well developed in all the 
ecies. 
Subcosto-radial Cross-vein (Sc-r).— This eross-vein is present in lucia, 
ianthina, doroxena, calliarcha, caustica, q rijuga, eodora, and chrysargyra. 
It is absent in ?ncongruetia, 
aurella (a trace sometimes), barbarica, demissa, rosicoma, and zonodoza. 
In the last two there is not even à bend in the veins to indicate where the 
cross-vein originally joined. ei : 
Radius (R).—The radius forks into Ria and Ri, before 4 in all species ; 
both branches are strong, well-developed veins. — ; 
Radial Sector. (Rs).—The radial sector is twice dichotomically forked. 
В, Б 1n ucilia the secondary radial 
species, the next farthest 
being calliarcha. The forking of В, is fairly uniform as to position in 
all the species, but that of R,_, varies considerably. In demissa, rosi- 
coma (fig. 6), zo and caustica R,-5 18 short-stalked ; in eodora, 
barbarica, calliarcha, and inco the stalking 1s medium (about half- 
way); in chrysargyra, aurella, and quadrijuga the vein is long-stalked ; in 
lucilia and ianthina the branches are connate in оп 
ft i 
Fourth Median Vein (M,).—M, usually rises fr 
of mf’; it connects with Сш at the forking of the. І 
cases its apex is farther distad than its base. This arrangement is most 
noticeable in lucilia and calliarcha. In rosicoma and zonodoxa the point
