Type flava Walker (Cat. Brit. Mus., V, 1107) ; also citrina Schaus 
are before me. 
Family MEGALOPYGID/E. 
Genus Aidos Hiibner. 
1818 — Aidos Hubner, Verz. Bek. Schmett. 191. 
1S95 —Brachycodion Dyar, Can. Ent. XXVII, 244. 
This has the venation of amanda , but veins 8 and 9 form a rounded rather than an 
angular furcation and 10 and II are very shortly stalked together. On hind wings 
veins 3 and 4 are shortly stalked ; 6 and 7 separate and parallel; 8 free to base. 
Type amanda Stoll; also yamouna Dogn. ( Eucleayamouna Dognin, 
Le Nat., XIII, 126) from Mr. Schaus’ collection. 
Genus Brachycodilla, nov. 
Antennae lengthily pectinated on basal half, terminal half simple (serrate), the 
regions sharply marked ; head sunken, palpi short, porrect, just reaching frontal tuft. 
Robust, vestiture suberect; legs rather long, posterior tibiae with terminal spurs only. 
Venation essentially as in Aidos ( vide Can. Ent., XXVII, 244), but vein 8 of hind 
wings is joined to subcostal by a strong bar at the end of the cell. 
Type castrensis Schaus (Journ. N. Y. Ent. Soc., IV, 56) ; also B. 
carmen Schaus (Talima carmen Sch.) and B. admirabilis Schaus 
( Perola admirabilis Sch.) are before me, the latter retained in my 
collection by the kindness of Mr. Schaus. 
Genus Cyclara Schaus. 
1896 —Cyclara Schaus, Journ. N. Y. Ent. Soc. IV, 57. 
Besides the characters given by Mr. Schaus, vein I of fore wings has a long 
branch on the lower side (characteristic of the Megalopygidae) ; vein 6 arises above 
the concavity of the cell ; cell broad ; stalk of veins 7 and 8 drooping from that bear¬ 
ing 9 ; hind wings with veins 6 and 7 remote and parallel ; 8 touching the cell ex¬ 
cept at base and extreme apex. Antennae much shorter than half of fore wing, but 
not disproportionately short as the body is slender, pectinated to the tip ; eyes large ; 
palpi very short, almost rudimentary, not reaching the front; legs slender, rather long, 
hind tibiae without spurs. A fragile insect, with proportionately large rounded wings. 
Type ovata Schaus. Mr. Schaus’ type is before me.
