to examine it. It bears Chambers' handwriting on the label, '''' St7'ol>!x/a 

 alhaciliseeUa Cham.," and it is undoubtedly authentic. 



It is clearly a Menesta^ agreeing- perfectly in venation and palpi with 

 this genus, and is very closely related to the two other species in the 

 genus, l)ut is at once distinguished by the white apical cilia in fore- 

 wing, which contrasts beautifull}' with the very dark shining wing. 

 I have only seen one other specimen of this fine species, namely, in 

 Mr. Keai"fott\s collection, where is found a well-preserved specimen 

 collected ])y him in New Jersey, on June 17. 



STROBISIA Clemens.

This genus is well characterized ])y Clemens, and has the following 

 characters: 



Labial jialpi perfectly smooth, curved, slender; second joint scarcely 

 thickened, terminal joint as long as second, pointed. Forewing elon- 

 gate ovate, apex obtusel}^ pointed; 12 veins, 7 and 8 stalked, or 11 

 veins, 7 and 8 coincident, 2 and ?i stalked. Hindwings narrower than 

 forewing, apex o})tuse, termen slightl}^ sinuate; 8 veins, 3 and -l con- 

 nate, 5 parallel, (> and 7 connate. The species have dark hindwings 1 

 and brilliant iridescent markings on forew^ings. The genus is nearl}^ 

 related to Trichotaphe Clemens. 



Two species hitherto placed in this genus I have transferred to 

 other genera, namely, levi/peddhi Clemens, which l)elongs to Ana- 

 cam/psh^ near tristrigella Walsingham, and will be found treated under 

 that genus (p. 841), and alhacilmeUa Chambers, which l^elongs to and 

 will ])e found treated under Menesta. 



The name argenticilieUa Chambers as found in Chambers' "Index," 

 p. 162, and in Smith's check list, No. 5581, does not appear to corre- 

 spond to any description. The reference given in " Index ''^ is not 

 correct, and the name must be dropped. 



Only two described species are at present referable to this genus. 

 They ma}^ be separated thus: 



Metallic markings, narrow dashes and dots irridipennella, p. 904 



Metallic markings, broad spots and bands emblemella, p. 905
