OF WASHINGTON, VOLUME XI, 1909. 213 



Thorax dark gray with a long slender appressed tuft of black hairlikt- 

 scales reaching back over the first abdominal segment. Forewings with 

 costa straight to apical third, there sharply deflexed, apex bluntly 

 pointed, termen rounded, dorsal edge straight; color brownish gra\ 

 with narrow ochreous edges and with three transverse, oblique, nearly 

 parallel, narrow lines ; the first from basal fourth of costa somewhat 

 undulated to apical third of dorsal edge; the second also somewhat 

 curved from about the middle of costa to just above the anal angle and 

 the third, which is nearly straight from just before the deflexion of the 

 costal edge to the middle of termen. Cilia short, dark fuscous. Hind 

 wings over 1, triangular with rounded apex and anal angle bright ochre- 

 yellow.' Underside of all wings bright ochre-yellow. Legs ochre- 

 yellow : first pair with the anterior side of the tarsi gray and heavily 

 -caled as in some noctuids ; posterior tibiae with long smoothly ap- 

 pressed hairs above ; the first tarsal joints similarly thickened with 

 shorter hair. Abdomen ochre-yellow with rich chestnut-brown liar- 

 above, one on each joint. 

 Alar expanse, 43-50 mm. 



Habitat Orizaba., Mexico, June (R. Miiller, coll.); Yera 

 Cruz, Mexico (H. Schwarz, coll.).

This species would, on account of the striking- wing" form 

 and the peculiarly thickened front tarsi, fall in Zeller's genus 

 l.oxotoma, which I, however, am unable to consider a g-ood 

 g - enus. The family Stenomidse, which is a primitive family 

 from which the family Oecophoridae has probably developed, 

 exhibits a very wide range of specific specialization, but has 

 differentiated itself into very few tenable genera. The trans- 

 ition of the various forms of the wing's and of the numerous 

 secondary sexual characters, tufts and fringes, exhibited in 

 this family, is so gradual as to defy generic division, while the 

 venation is remarkably uniform throughout the family. It 

 seems at the first study impossible to place a species like the 

 present or the similarly shaped type of the genus Lo.votoum 

 (.elegans Zeller) in tte same genns with the superficially very 

 different typical Stcnoina species; but if the recogni/.cd generic 

 characters are compared one by one, they will be found to be 

 identical and the present Species is, for example, undoubtedly 

 quite as close to Sleinnna Iri^lri^n/n Zeller as to J.o.\-otoi>in 

 /t^a//s Zeller, though the former could not be placed in Zel- 

 ler's genus Loxoioma.
