joined by cross-vein in outer fourth; ist anal vein obsolescent; Ms near Ms, Mi 

 from upper angle of cell; Rs and R4 stalked, Rj and R: from areole, Ri from 

 middle of cell ; secondaries, M:, Ms, Cui, close together from near lower angle of 

 cell; R and Mi from a point or stalked; subcostal cross-vein present or absent; 

 cellula intrusa on both wings ; frenulum well developed, reduced, or rudimentary. 



The genus Givira as defined by Walker is not readily recognized ; 

 Schaus, however, has defined it very exactly in Jour. N. Y. Ent. Soc, 

 IX, p. 48. His genus Eugivira, which only differs from Gk'ira Walk, 

 in that R and Mj of secondaries are stalked and not from a point, is 

 hardly sufficiently removed to warrant the name; Dyar has evidently 

 united it with Givira in his Synopsis. (Proc. Nat. Mus. XXIX, p. 

 339). Inguromorpha Hy. Edw. seems undoubtedly a synonym, as 

 Dyar's definition of it agrees exactly with Giz'ira; we cannot agree 

 with Dr. Dyar in his statement (Ent. News, X, p. 129) that in arbe- 

 loidcs the basal }i of ist anal vein is entirely lacking; on our specimens 

 it is reduced but still present, making arbcloidcs correspond with the 

 type species of Inguromorpha; arbcloidcs was placed by Schaus in 

 Eugivira. 



The species basalis Wlkr., and franccsca Dyar are only known to 

 us by photographs, but are probably correctly placed, as Dr. Dyar in- 

 forms us a cross-vein exists between anal veins.
