The flattened vibrissae of this species are apparently unique in 

 the genus. 



8. Odinia coronata, new species 



Species with numerous large dark spots in wing, and slender vi- 

 brissae, 



Male: Color as described for 0. williamsi except as follows: Lower 

 portion of second antennal segment with black stripe on outer surface, 

 but inner surface reddish; mesonotum with brown spots about bases 

 of bristles and hairs, and a large, irregular brown spot encompassing 

 and mesad to the base of each fourth dorsocentral bristle, but no 

 median brown stripe; in darkest specimens a brown stripe on each 

 side of mesonotum mesad of humerus and extending caudad through 

 bases of presutural and supraalar bristles to the postalar bristle; 

 mesopleuron predominantly gray, dorsally with a narrow brown stripe, 

 sometimes only a trace of brown ; wing pattern (fig, 8) similar to that 

 of williamsi but darker, the median spot in marginal cell and that 

 encompassing the hind crossvein conspicuously larger and darker. 



Front slightly narrower than in williamsi, 1,77 times the width 

 of an eye and 0.47 times the width of head, with a few minute hairs 

 as in williamsi; vibrissa long and slender, the adjacent oral bristles 

 slender and almost hairlike. Mid tibial apical bristles as in williamsi; 

 hind femur incrassate as usual in males, but not unusually so, the 

 length 2.07 times the greatest diameter; hind tibia as long as hind 

 femur; the latter with one strong preapical antero ventral bristle. 



Female: As described for male, except for the following: Front 

 broader, 1,3 times its own length, twice the width of an eye and one- 

 half the width of the head; hind femur not enlarged. 



Length of body and of wing, 3,5 mm, 



Holotype male (USNM 64275) and allotype, La Union, El Salvador, 

 Jan. 25, 1957, P, A, Berry (no, 807). Paratypes (in USNM): 2 

 females, same data as holotype; male, La Campana, Panama, Janu- 

 ar3'^-March 1938, James Zetek; male. Palm Beach, Panama, Sept, 17, 

 1952, light trap, F, S, Blanton; female, Harlingen, Tex., Aug, 8, 1931, 

 R. L, Clayton; female, Allen, Tex,, Aug. 14, 1931, F. O. Swan. I have 

 also seen two males in poor condition, not included in the type series, 

 one with same data as the holotype and one with same data as the 

 paratype from Allen, Tex. 



This species is a near relative of 0. williamsi from the Galdpagos Is- 

 lands. The form of the vibrissae is the only difference of consequence.
