Oropeza obscura Johns. 



1909 Oropeza obscura Johns. Proc. Boston Soc. Nat. Hist., vol. 34, p. 122. 

 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, Eurypogon 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 LXXXVI, 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 LXXXVI, 467) seven-toothed, median point long and slender, a pro- 

 longation of outer mental plate. Hypopharynx (Plate LXXXVI, 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 cardq large, triangular, with two setifero us 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
