Subfamily ACROLOPHIN^ 



(Anaphorinae; Psychidse, in part, of Kirby and Tutt) 



Head retracted; eyes medium-sized, usually hairy; ocelli absent; palpus large, 

 with the first joint large, upturned to the middle of the front, and, in the west- 

 ern genus Eule piste, as long as the other two together; the palpus as a whole 

 often upturned to vertex, or even far beyond, especially in the male; in the 

 female, typically porrect and shorter. Maxilla obsolete. Antenna with some- 

 what globular scape; the shaft smoothly scaled above, sometimes in more than 

 two rows, and finely pubescent with sense hairs below; in male, laminate, rarely 

 pectinate. Vestiture of head, including palpi, thorax and femora, reugh, but fine 

 and very dense, largely of spatulate hair; abdomen also rather hairy; R 6 of fore 

 wing running to outer margin. Hind tibia hairy rather than bristled. 



Larva (fig. 91) with front reaching only halfway to vertex, the adf rentals 

 very wide and reaching vertex; ocelli six, but not regularly arranged, the fourth 

 and lower being much closer together than the second and third are; head ven- 

 trally chitinized behind labium. Leg with trochanter one-third as wide as femur; 

 prothoracic legs separated by a distinct, chitinized sternum; thorax with setae 

 on large shields; tubercles iii to v apparently taking the place of pleural sclerites; 

 cervical shield extending the whole width of the prothorax and enclosing the 

 spiracle; prolegs with one complete ellipse of hooks, preceded by several (3-6) 

 rows of rudimentary ones; the anal proleg with a curved band. 



The larva of one species is known to live in a tube near the surface of the 

 ground, feeding on grass and the like, and pupating in the ground. 



Pupa heavily chitinized, suited for coming up through the earth; antenna 

 shorter than fore wing; fore wing bluntly rounded. 



This group is entirely American, and predominantly tropical. Besides Acrolo- 

 phus there are a couple of other well-defined genera.
