365 
Epicranium with normal number of primary setae, 13, and punctures, 7, and with 
three small ultraposterior punctures (x, y, z). 1 
Anterior setae (A lf A 2 , A 3 ) in an obtuse angle; A x and A 2 closer together than A 2 
and A 3 ; anterior puncture Aa posterior to A 2 and on a line with A l and A 2 ; A 3 directly 
lateral to Aa. Posterior setae (P x , P 2 ) and posterior punctures (Pa, Pb) near the middle 
of the head; P t and P 2 on a level with AdL and Adf 2 , respectively; Pa on a line between 
Li and P 2 , nearest L { ; Pb on a line between F l and P 2 , approximate to P 2 . Lateral 
setae (Li) closer to A 3 than A 3 is to A 2 , anterior to P x ; lateral puncture (La) directly 
posterior to, and distant from the seta. Of the ocellar setae ( 0 lf O a , O a ) O x is equi¬ 
distant from and lateral to ocelli ii and iii; 0 2 closely approximate to and ventral to 
ocellus i; 0 3 posteroventral to and remote from 0 2 , on a line with ocellus v and vi; 
ocellar puncture (Oa) between and equidistant from 0 3 and ocellus vi. Subocellar 
setae (Soj, So 2 , So 3 ) triangularly placed, nearly equidistant; subocellar puncture 
(Soa) between and equidistant from So 2 and So 3 . Genal 
seta (G x ) and puncture (Ga) both present; seta anterior to 
puncture. 
Labrum (PI. 10, A, B) with median incision acute, rather 
deep. The three lateral setae (La 1? La^ La 3 ) close to the 
edge; La x and La 2 approximate, La3 remote. Median setae 
(Mj, M 2> M 3 ) in the usual Micro arrangement with M 2 latera 
and slightly posterior to M 2 ; M 3 well back of anterior 
margin; M x and M 3 equidistant from M 2 . M x on a line 
with L&j; M 2 slightly anterior of Laj. 
Epipharyngeal shield (ES) small, arrow shaped; epi¬ 
pharyngeal setae (ET) broad plates, triangularly placed; 
epipharyngeal rods not discernible within the labrum 
proper; posterior projections short. 
Mandibles (fig. 7) longer than broad; 5 teeth, 4 lower 
teeth long and sharply pointed; upper fifth tooth rounded; 
one long and one shorter seta on upper side near lower 
edge. 
Labium and maxillae normal. 
Antennae four-jointed, with second joint more than half. Fi G . 7—Pyroderces riUy'%: Right

Three pairs of normal thoracic feet; four pairs of abdom- enlarged ' ^ ori « inal ) 
inal prolegs with unevenly biordinal crotches, arranged in a complete circle; anal 
prolegs with a transverse line of biordinal crotches. 
Setal arrangement of body normal, as shown in figures C and D, Plate 11. 
Pupa. —Pupa smooth, with setae on vertex, first thoracic, and on all but the first 
abdominal segments. No cremaster. 
SPECIFIC DESCRIPTION 
Moth (PI. 7, B ).—Labial palpi light reddish brown; second joint with two ill- 
defined darker brown annulations; terminal joint with three blackish annulations. 
Head light chestnut-brown; lower face yellowish iridescent. Antennae whitish with 
sharply defined, narrow, blackish brown annulations. Forewings chestnut brown 
with whitish straw-colored streaks, edged by irregular black scales; an oblique 
whitish fascia on basal third edged on the inner side with black; an ill-defined group 
of black scales in the middle of the wing, edged with white; a subcostal longitudinal 
white streak at apical third, terminating in black scales; a similar, fainter, subdorsal 
streak terminating in black scales at apex of the wing; cilia yellowish gray. Hind
