11 Larva* —Determined on four specimens, drawn from comparison 
of the four. 
General appearance—A slender larva with much pigmentation in 
median strip. 
Antennae—No branched hair on shaft, terminal spines, equal, hair 
divides into three branches. 
Prontal hairs—Three pairs; anterior median and posterior vary 
(see plate). In three of the four specimens the external hair is 
dendriform, in the fourth it is rather penniform in shape. This larva 
was taken from a small collection, of which some five or six developed 
into imago of squamosa. 
The exact shape of the hair is scarcely appreciable under a lower 
magnification than x 100, and is readily overlooked and can scarcely 
be differentiated in the living larva. There is no other difference. 
Palmate hairs—Rudimentary on thorax, well developed on first 
abdominal segment and exceptionally large on second to seventh 
inclusive. The leaflets are relatively narrow and few, about 16 in 
number (as in Jacobi), in contrast to ardensis, in which they are 
broad and numerous—about 25. 
Average radius 0'144 mm. 
Average relation of filament to total length of filament and leaflet 
as O'36 is to 1. Maximum O'40 ; minimum O’35. 
Habitat. —Found occasionally on coast and at levels of 2,000 ft. 
to 2,800 ft. ; once in residual pools in a river bed, and three 
times in marshy pools directly fed by small springs.
