nected across 1st A to Ou by an 

 apparent cross vein, no distinct 

 vein below the lower fork of 2d A; 

 jugum overlying hind wing. Hind 

 wing with similar venation but 

 with SCi lost, anal system reduced, 

 and no jugum. 



Egg spherical, apparently of the flat type ; studded with blunt- 

 tipped spines, white or yellowish; the eggs laid in small clusters in, 

 and under, wet moss. Caterpillar of a slug-caterpillar type, poly- 

 gonal in cross section, exceedingly thin-skinned, and soon shriveling 

 if allowed to dry; with two double rows of socketed scales on each 

 side (fig. 35), irregular on prothorax and last segments; ninth abdom- 

 inal segment well developed. Prolegs represented by conical processes 

 on first eight segments of abdomen, with a large sucker on the ninth 

 and tenth. True legs normal. Head with mouth turned forward, 

 eye apparently single and dorsal. Antennas longer than head, the 

 second segment the longest. Food wet moss, the known species feeding 

 on Hypnum and liverworts. Pupa in a dense, parchment-like cocoon, 

 with large, crossed mandibles ; not well known. Hibernation probably 

 as larva in the cocoon. 



Distribution probably world-wide ; about 35 known species. 



The imagoes feed freely on the pollen of various flowers, using both 

 mandibles and maxillae.
