Family MEGALOPYGID^E. 



Genus Aidos Hiibner. 



1S1S — Aidos Hubner, Verz. Bek. Schmett. 191. 



1895 — 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 11 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 yamonnaDogn. (Bttc/ea yamounaDognin, 

 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. admirabills Schaus 

 (Bero/a adinirabilis 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 Megalopygidre) ; 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. Antennce much shorter than half of fore wing, but 

 not disproportionately short as the body is slender, pectinated to the lip ; eyes large ; 

 palpi very short, almost rudimentary, not reaching the front ; legs slender, rather long, 

 hind tibice without spurs. A fragile insect, with proportionately large rounded wings. 



Type ovata Schaus. Mr. Schaus' type is before me.
