Alphabetical List of the American Lymantriid Genera. 
lacteolaria. 
lephassa. 
9 and 10 stalked; 11 free. Hindwing broad; costal margin straight; termen well rounded; veins 3—5 as 
on fore wing; 6 and 7 stalked; 7 close to 8 to end of cell. 
Type: L. lacteolaria Hulst. 
L. lacteolaria Hulst. (75 c). <$. Palpi, head, and collar pale yellow; shaft of antennae white, the 
branches fuscous. Body white. Wings white, thinly scaled. Forewings: basal third of costal edge fuscous; two 
fine parallel drab lines, the first from subcostal towards end of cell, inbent to inner margin at one third from 
base, the second from vein 10; 2 minute drab streak on discocellular. Expanse: <$ 24—30 mm, $ 42 mm. 
Arizona; Mexico; Guatemala. 
L. lephassa Drc. (= dianaria Dyar) (75 c). Differs from L. lacteolaria Hulst. in the absence of 
lines on forewing, and the branches of antennae are wood brown. Expanse: 26 mm. Mexico. 
Note. In Stiibel Beise p. 132, pi. 5, f. 9 a Leucoma pasaleuca is described and figured, but judging from the venation 
it is not a Lymantrid. 
The type of Microrgyia aniazonum Fldr. is lost as stated by Dr. K. Jordan, its position therefore not to be 
ascertained. 
Geometrodcs mimica Fldr. is a Geometrid; as stated by Dr. K. Jordan, the specimen is in good order and exhibits 
- in spite of vein 5 arising from lower angle of cell — the structures characteristic of Geometridae, a well developed proboscis, 
ocelli, the Greometrid abdominal tympanun etc.
