still quite unable to divide our series in a satisfactory way. We must 

 therefore leave the species as a small, variable, pale coloured Oidac- 

 matophorus, without strict definition. The larger specimens are from 

 Utah, and approach caudclli Dyar, but lack the prominently dark-lined 

 veins in the lobes of the primaries. 

 The life history is unknown.

The species is still known only from the unique type 9 , so we reproduce 

 the original description and notes. 



"Primaries pale straw-color, immaculate, slightly tinged with smoky along 

 terminal margins of lobes ; first lobe pointed, second lobe rather broad with 

 well defined upper angle. Secondaries pale smoky with lighter silky fringes. 

 Beneath, smoky. Legs pale ochreous, first two pairs blackish inwardly. Ex- 

 panse 14 mm. 



"Habitat. Marco, Fla. (Apr. 24-30). 1 9. Type, Coll. Barnes. 



"From several larvae, found boring in the stems of the Eupalorium species 

 above referred to, we succeeded in breeding this single specimen." 



We would call attention to the fact that the type has a brown 

 head with a whitish patch between the antennae, and that vein Rj, and 

 all of those in the second lobe of the priinaries are distinctly marked 

 vvitli smoky brown, most heavily in the outer margin. The thorax 

 and abdomen are pale yellowisli white, the latter with a dorsal and 

 several ventral and lateral brown stripes. We associate with the 

 type a single other 9 from St. Petersburg, Fla., Oct., whose expanse 

 is 19 mm., but we are not at all certain of the identity of this specimen.

 Head light brown, yellowish white between the antennae. Palpi moderate, 

 oblique, whitish, slender. Antetmae whitish. Legs whitish, the first two pairs 

 shaded with fuscous inside; tibiae of hind legs slightly shaded outside. Thorax 

 and abdomen yellowish white. Abdomen apparently with a few faint brown 

 stripes. We have few specimens in which these can be observed.
