almost concoloroas with primaries. The cliscal dots are larg;’e and distiuct, exactly as in 7). drexeUL 
Otherwise the motli is the same as its allies. 
Expanse ot wings, 47-00 mm. 
From I), dvexclu it differs in the absence of the bright costal shade, the more uniform coloration 
from I), ministra, as alreadj^ pointed out under that species. With the other species it could 
scarcely be confounded, (Dyar.) 
— Of nearly the same size and shape as in that of J>. (IrexeUi, but considerably smaller 
than that of J>. imhniL Differs from that of i>. drexelii in the upper end with the n)icroi)yle being 
somewhat depressed. It Ls round, barrel- shaped, the shell porcelain white. Tlie micropyle is 
somewhat larger than that of I>, drexelii. Described from living si)eciinens received from Miss 
C. G. Soule. 
Larva, — I have not seen the larva alive. The excellent figures kindly loaned me by Miss 
Morton well represent this species, which is readily recognized by its checkered ai)peara7ice. ‘ 
The following description of the eggs and larval stages has been kindly sent me by Dr. Dyar:- 
E(jif, — Laid in i^atches of 90, 95, 102, on underside of leaf of the food plant, lindromeda 
liguHtrina. Cylindrico-pyriform, being of less diameter just below the summit, flattened at base- 
and vertex. LTniform white, with a rather large central black spot at vertex. Diameter, 1.1 mm.f. 
height, 0.7 mm. 
Larra^ Jirst stage, — Head round, shining black; width, O.o mm. ; cervical shield, anal idate, 
thoracic and anal feet, and leg-idates black. Body wine-red, a broad subdorsal and lateral yellow 
band, each containing a narrow red line. No lines on venter. Hairs, several from a wart, the- 
warts minute, dark brown; no secondary hairs. 
fSccoiid stage, — Head shining black or with a slight brownish tint, rounded, rather higher than 
wide; width, 1,1 mm. Body dark wine-red, Hie bands as before, greenish yellow; venter with a. 
narrow central pale yellow line. Later the bands become almost white. Besides the hairs froiu 
the warts, short, fine, secondary hairs are xiresent on the skin. 
Third stage, — Head higher than wide, narrowing toward apex, the sutures depressed. Color 
red-brown, the ocelli and mouth black; width, l.G m. Cervical shield black or iiartly orange; feet 
and anal plate shining black. Body blackish brown, the stripes at first as before, but later they 
appear as four very broad, lateral, clear white (or bright yellow) bands, with slight traces of the 
ventral lines. In a few the pedal line is tolerably distinct, but narrow. Bases of the legs and 
corresponding spots on legless segments dark wine-red. Hairs not abundant, pale, the secondary 
ones very short. 
Fmrth stage , — Head as before; width, 3.1 mm. Body black, the side stripes much broader 
than the intervening spaces, continuous, clear white (or yellow). The A'entral stripes (two pedal 
and medio- ventral) are represented by a few linear dots yr are absent. Cervical shield light brown 
anal plate black or partly brown. Thoracic, anal feet, and leg plates black, the bases of the feet 
red, as before. The stripes are not confiiient at either extremity. 
Fifth stage , — Head rounded, as high us wide, shagreeiied, shining; color, orange-brown or 
light mahogany-red; Avidtli, 5.3 mm. Cervical shield, anal plate, bases of legs, and corresponding 
spots on legless segments mahogany-red. Anal and thoracic feet blackish. Body black, the 
ventral lines as l)efore, but the lateral are broken by the black ground color into a series of 
subquatlrate spots, as follows: The two upper lines are broken in all the segmental incisures and 
broadly through the center of the segment; the ihird (lateral) is broken in the same mannei’, but 
less broadly in the center of the segment, while the fourth (siibstigmatal) is not broken in the 
incisure nor center of the segment, but once before the spiracle and again toward the imsterior 
edge of tlie segment. The spottings are i>artially obsolete at the extremities. Primary hairs 
arising from tlie wart-areas long, white; secondary ones veiy short, black. There are two forms 
of this larva in which the spots are i>urc white or bright yellow, respectively.

Pupa. — 6 and $ . Head rather xironiineut, roughly corrugated, with the three frontal ridges 
moderately well marked; the head is broader and the ridges less marked than in D. perspicua. 
Thorax and body coarsely punctured, but not so much so as in D, perspicua.,. The body Ls less dull,,
