Mr. Hyslop has sent to the writer, at various times during the past 
two or three years, larvae of Oropeza obscura. Numerous larvae and 
one pupal skin were found under dry moss (Hedwigia albicans [Web.] 
Lindb.) on rocks in the South Mountains, Maryland, on November 4, 
1916, by H. L. Parker. They were associated with the larvae of a dascillid 
beetle, Hurypogon niger (Melsh.). Additional specimens were found in 
a decaying log, but the preferred habitat seems to be beneath moss. The 
dark green larvae are very sluggish. 
Larva.— Length, 11-12 mm. 
Diameter, 1.7-1.8 mm. 
Color dark brownish green, ventral surface clearer green. 
Form depressed; body short and stout. Dorsum covered with small, blackened points, 
producing the dark color of this region of the body. Segments much wrinkled, especially 
on basal ring. On each side of penultimate segment a stout tubercle which simulates dorsal 
lobes of spiracular disk. Spiracular disk (Plate LX X XVI, 469) moderate in size, surrounded 
by six fleshy lobes, dorsal pair short and slender, lateral pair long and slender, ventral pair 
very short and blunt; ventral lobes sparsely fringed with short, black hairs, and with a pale 
apical area bearing a sensory bristle; inner face broadly suffused with brown; at base of 
other lobes similar but smaller triangular brown marks; a dusky area ventrad of spiracles. 
Spiracles large, placed obliquely. Anal gills four, large and blunt, pale yellow. 
Head capsule of the massive tipuline type. Labrum broad, with a short, blunt lobe on 
either side; median epipharyngeal region with dense rows of stout setae and two small 
papillae on margin; lateral lobes with about four or five sensory bristles or papillae of various 
sizes. Mentum (Plate LX X XVI, 467) seven-toothed, median point long and slender, a pro- 
longation of outer mental plate. Hypopharynx (Plate LXX XVI, 468) five-toothed, the 
three intermediate teeth the largest, lateral tooth on either side small. Antenna slender, 
cylindrical, with apical segment very reduced. Mandible rather slender, with about seven 
blunt teeth on margin. Maxilla with cardo large, triangular, with two setiferous punctures, 
the outermost very large and hyaline and with two long, powerful setae; lobes of maxilla 
fringed with dense hairs; palpus short, disklike, with a large group of tiny hyaline papillae 
at apex. 
Pupa— Length of cast skin, about 12 mm. 
Coloration brown; pronotal breathing horns dark blackish brown. (It is possible that 
the pupae when alive are dark green in color, like the larvae.) 
Labrum triangular. Labial lobes large, separated by apex of labrum. Sheaths of maxillary 
palpi short and stout, apex recurved to beyond midlength. Antennal sheaths moderately 
elongated. Pronotal breathing horns elongate, slender, cylindrical, tips a little expanded. 
Mesonotum on either side of median line with a large, roughly triangular, reticulated area 
which is slightly elevated, with apex of triangle directed toward mid-dorsal line. Mesonotum
