some Pterophorids. Head rounded, flattened before, held flatly, 

 rather thick and 'not markedly bilobed, apex in joint 2. Whitish, 

 thickly streaked with red brown over the sides and vertex, leaving the 

 face and a streak on the front of the lobe above broadly pale, enclos- 

 ing a brown dot at tubercle ii ; sutures of clypeus brown, mouth sor- 

 did. Body without cornified shields, the tubercles small, marked in 

 velvety black, ia + ib, iia + iib, iv + v on thorax, iv -f v on abdo- 

 men, vii of three distinct tubercles in a line. Broad whitish dorsal 

 and substigmatal bands, the dorsal one continuous on joints 2 to 

 13, the substigmatal one obsolete at the ends. Sides finely streaked 

 in blackish, largely transversely so, with traces of a pale subdorsal line 

 and containing large black spots on tubercles i, ii and iii ; subventer 

 blackish mottled but less distinctly than the sides and more diffusely ; 

 venter grayish shaded except between the feet. Feet all pale, the 

 thoracic ones brownish tinted. The larvae are in alcohol and I cannot 

 determine whether the general color when living was whitish or green- 

 ish. Mr. Schwarz does not recollect what the life habits of the larvae 



Ethmia subcserulea IVa/s. 



Near to discostrigella and perhaps only a local form of that species. 

 The bright gray ground color is only a little obscured by blackish 

 scales. The male genitalia are the same.

Ethmia confusella Walk. 



I identify six specimens from Key West, Florida, as this species. 

 The ground color is light gray with very numerous black dashes and 

 dots. The anal plate ends in a single spine. Side pieces broad, 

 rounded, curved inward at the ends, with a curved, thick spine at 

 upper angle, both this spine and the anal spine dark brown. 



Ethmia josephinella, sp. nov. 



Thorax rubbed, the patagia white. Fore wings ochraceous white, the costal 

 half shaded with brown in a dense irroration, its lower edge in the cell composed of 

 a number of large, rounded, confluent spots and a spot on vein 4, above which a pro- 

 jection runs out almost to the margin ; four spots below the median vein, somewhat 

 diffuse, and a patch of scales about the middle of the inner margin ; a row of terminal 

 dots. Hind wing pale, semitranslucent, dark at tip. Abdomen ochraceous. Ex- 

 panse, 24 mm.
