SIX NEW OR LITTLE KNOWN LARVAE OF PTEROPHORIDAE. 



BY HARRISON G. DYAR, WASHINCTON, D. C. 



Tric/iopiilns lobidac/ylus Filch. — Head 

 faintly brownish, retracted at the apex under 

 joint 2 ; width .7 mm. Body shining green, 

 serai-transparent ; no marks ; tracheal line 

 faintly showing by transparency, dorsal 

 vessel darker. Warts rather few haired, i 

 and ii united into a single wart, iii small, a 

 single hair above and behind spiracle (iiia) 

 iv and v united, vi and vii small ; a few short 

 secondary hairs subventrally ; all the hairs 

 glandular and gummy, swollen at the tips 

 even without a lens and often with drops 

 along the shaft. The hairs are sordid white, 

 sparse, and rise i mm. above the dorsum. A 

 row of minute, impressed, black dorsal dots 

 on joints 5 to 11. At the bases of the several 

 haifs are brown rings, causing the warts to 

 appear slightly discolored. In J larvae the 

 sex-glands appear in joint 9, yellowish, not 

 pronounced. 



Pupa. Attaclied by the cremaster; with- 

 out winged elevations; green, vinous patch 

 on segments 4-5 of abdomen. Head rough- 

 ened with coarse tubercles, vinous brown ; 

 thorax obliquely truncate anteriorly, 

 rounded ; hairs shorter and fewer than 

 in the larva, scarcely glandular. Length 

 8 mm. 



On smooth leaved golden-rod (Solidago), 

 Van Cortlandt Park, New York City, May. 



OxvptHiis tenuidactylus Fitch. — Head 

 green, .7 mm. wide. Body pale green, with a 

 faint sub-dorsal white band. Warts i and ii 

 united, bearing about ten setae with simple 

 ends ; iii with six setae ; a small wart behind 

 it with two setae (iiia); iv + v with two 

 large setae and several small ones; a single 

 seta behind this (iii b) ; vi with a distinct 

 tubercle, but somewhat confused ainong the 

 secondary hairs ; vii of three large setae with 

 several shorter ones ; secondary hairs scat- 



tered o\'er tile bodv, and these as well as 

 some shorter ones from tlie warts, liave 

 s\^■ollen or cleft tips. 



Pupa. Slender, tapering behind, fastened 

 by the cremaster. A row of sub-dorsal tu- 

 bercles bearing four spines in a fan-like ar- 

 rangement, continued as a carinated ridge 

 on the thorax. Thorax widened, the cases 

 produced into a point along the abdomen. 

 Two slight points above the eyes. Whitish 

 green, cases more greenish. There are sev- 

 eral spines on the thorax, and some fine, soft 

 hairs on abdomen laterally. Another pupa 

 was light purplish brown. 



On the buds of blackberry (Rubus), Keene 

 Valley, N. Y., June. Found with Butalis 

 basiliin's Zell., but more closely resembles 

 the blackberry buds than this Tineid does. 



Pterophorus rliynchosiue n. sp. — Expanse 

 18 mm. Head and thorax yellowish gray; 

 abdomen neatly lined with brown ; a luedio- 

 dorsal and six lines on each side; abo\'e, the 

 first and tliird segments are tufted with white 

 posteriorly; legs pale yellow, white towards 

 the tips, narrowly lined with brown longi- 

 tudinally. Fore-wings yellow-gray ; a small 

 double black dot at base of fissure, and one 

 half way between this and base ; a minute 

 dot towards apex of first lobe. Fringe pale, 

 the outer third on first lobe black ; terminal 

 part of fringe of second lobe blackish, basal 

 part pale, cut by five black wisps ; the fifth at 

 apex. Hind wings blackish, a black dot at 

 apex of each lobe; base of fringe of third 

 feather whitish, contrasting. 



Larva. Downy, pale green, with short 

 white hairs. Pale green, the body tapering 

 a little posteriorly ; no marks except a very 

 faint, whitish subdorsal line along warts i 

 and ii; warts small, i and ii separate, but 

 somewhat approximate ; a small wart (iiia)
