the primaries being not dissimilar to a small specimen of L. uniformis. 

 In the genus Anarta its closest ally appears to be quadriUmata which 

 has rather similar maculation, and similar eyes, but is quite distinct. 

 The type was submitted to Dr. McDunnough to see if he could match 

 it with other material, but the specimen he submitted is not a very good 

 match, being somewhat darker, especially on the secondaries, when 

 normally one would expect the secondaries of the male sex to be some- 

 what paler. This specimen, also, is not in the best of condition, the 

 fringes rather ragged, and the antennae missing. Otherwise the 

 authors would have made the male the holotype.

Lasionycta marloffi Dyar. 



1922, Dyar, Ins. Insc. Menst., XI, 167, Anytus. 



This insect, described as an Anytus is a Lasionycta close to 

 L. perplexa Sm. and L. alberta B. & Benj., but presumably distinct on 

 minor genitalic characters as shown by topotypical specimens.^

1895, Grt., Abh. Nat Ver. Bremen, XIV, 74, phoca Mosch, designated

Proboscis fully developed ; palpi oblique, the 2nd joint fringed with hair 

 in front, the 3rd moderate, porrect ; frons rounded out, roughened, with or 

 without a slight vertical ridge, sometimes nearly heart-shaped due to the vertical 

 ridge becoming heavy and a slight indentation being produced at its base; a 

 corneous plate below; eyes moderate to large, rounded; antennae of male 

 ciliated; head and thorax clothed with hair and scales, pro- and metathorax 

 with spreading crests; abdomen with a dorsal series of crests which are weak 

 and easily lost and weak lateral fringes of hair. Fore wing with veins 3 and 

 5 from near angle of cell ; 6 from upper angle ; 9 from 10 anastomosing with 

 8 to form the areole; 11 from cell. Hind wing with veins 3, 4, from angle of 



SThanks are due to Messrs. Doll and Marloff for furnishing topotypes of marloffi; and 

 to Mr. Carl Heinrich who made genitalic slides while the junior author examined types in 

 the National Museum.
