The antennae will sufficiently distinguish this genus only the 



terminal four joints being bare of pectinations. 



ttacrorocampa n. gen. — Head moderate, retracted; eye.s large, naked; 

 palpi scarcely exceeding the front. Thorax wider than long; abdomen 

 exceeding secondaries; (^ antennae bipectinate for the basal 38 joints, the 

 pectinations longest centrally; the terminal 15 joints bare; fore wings 12- 

 veined ; median vein 3-branched, veins 3 and 4 arising close together; 

 cell closed by a concave cross-vein, from which arises vein 5 slightly above 

 the middle; veins 6 to 10 on a stalk out of the apex of the discal cell; no 

 accessory cell, or a very narrow one reaching from discal cell to the origin 

 of vein 7 (which is half way to the apex of the wing) showing a tendency 

 to be obsolete. Vein 1 1 arises from the subcostal about one-fifth its length 

 from end of cell; costa straight, apex subacute, outer margin convex. 

 Wings more than twice as long as broad; secondaries with two internal 

 veins; median 3-branched,. 3 and 4 arising together from lower corner of 

 cell; cell closed by a concave cross-vein, from which 5 arises a little above 

 the middle; 6 and 7 on a short stalk from the upper comer of cell; 8 runs 

 close to the subcostal till just before the end of the cell; it is slightly 

 sinuate, approaching the subcostal most nearly along the middle of the 

 cell. The wing is ovate, evenly rounded; hind tibiae with two pairs of 

 spurs.

The genus is distinguished by the very narrow obsolete acces- 



.sory cell, often wanting, and by the structure of the larva, which 



bears a pair of long tails, even longer than those of Centra.
