remains in close continuity with the first longitudinal vein, curving first 

 downward and then upward, and diverging from it only near the tip, and 

 then Imt little, being separated from it at its tip by scarcely more than the 

 thickness of the costal vein ; the transverse shoulder vein is slightly oblique; 

 the third longitudinal vein strikes the tip of the wing, and the second divides 

 the space between this and the costa, running for the greater part of its 

 length parallel to the latter, turning slightly upward at the tip: the third 

 and fourthjlongitudinal veins are pretty closely approximated, and parallel 

 as far as the transverse vein in the middle of the wing; from this to tin- 

 large transverse vein they diverge gently, and are again parallel beyond; 

 the small transverse vein is placed a very little before the middle of tin- 

 wing; the lariM- transverse vein is straight, nearly perpendicular to the e" 

 its lower extremity distant from the margin by about half its own length, 

 its upper extremitv dividing, just before the middle, the part of the fourth 

 longitudinal vein lying beyond the transverse vein : the fifth longitudinal 

 vein vanishes just before reaching the border; the two small basal cell- are 

 nearlv equal in si/.e, in length about midway between the lengths of tin- 

 two transverse veins. The wing is covered pretty abundant! v. veins and 

 membrane, with delicate microscopic hairs, and appear- to lie nnitonnlv 

 hyaline, though a little fuscous on tin- >h>ne. The specimen appears to lie
