PSYCHE. 



[March 1S93. 



tufts on joints 5 and 6 white, brownish or 

 black, on joints 7 and 8 pale yellow or 

 white. Pencils about 1.5 mm. long preceded 

 by some shorter, but equally black hairs. 

 Other hair blackish and yellowish mixed. 

 Retractile tubercles orange red. 



Sixth and seventh stages (the 7th in some 

 § larvae). — As before, except the brush 

 tufts are all alike, brownish white, darker 

 along the crest. There is a yellowish band 

 subdorsally on joints 11 and 12, and a sub- 

 stigmatal one, broken on each segment, but 

 reaching the whole length. 



Cocoon. — As in all the other species of this 

 genus. 



Pupa. — Structurally as in the other spe- 

 cies. Smooth, yellowish white, with more or 

 less black shading on the back, in some cov- 

 ering most of the surface and extending on 

 the under side. A few silky white hairs over 

 the surface and in some three tuft-like 

 structures on the back. 



Length $ 10 mm., $ 18 mm.; width $ 



3-5> ? 5-5 mm. 



Larvae from Nanaimo, B. C. 



Orgyia ANTiquA Linn.* 



nova Fitch. 



Egg. — As in O. badia ; laid without cov- 

 ering. 



First stage. — Like O. badia. 



Second stage. — As in O. badia, but there 

 are a few short black hairs from the dorsal 

 warts on joints 5-8. The orange retractile 

 tubercles now first appear. 



Third stage. — The hair pencils are now 

 present, 1 mm. long; also the brush tufts, 

 those on joints 5 and 6 black on joints 7 and 

 8 white, the one on joint 8 consisting of only 

 a few hairs. 



Fourth stage. — Body black, the warts ii 

 and Hi red; hair pencils 2.5 mm. long, black. 



* In Ent. Amer. Mr. Edwards describes accurately 

 stages i to iii of O. nova and then says there is no 

 change to maturity. This may be an oversight as the 

 lateral pencils do not appear till stage iv. But his 

 statements would imply that he was describing O- 

 badia. The larvae were from Houghton, Mich. 



From wart v on joint 5 is a white hair pencil, 

 not plumed ; from wart v on joint 6 a plumed 

 black one, both these 1.5 mm. long. These 

 lateral hair pencils are not seen in O. badia> 

 which the larva otherwise closely resembles, 



Fifth stage. — As before. The brush tufts 

 on joints 5 and 6 are faintly brownish, on 

 joints 7 and 8 yellowish, but nearly the same 

 color. The markings are as in O. badia. 



Sixth and seventh stages (7th stage some 

 $ larvae). — Head shining black, labrum and 

 bases of antennae white; width 2-8 mm.; 

 and 3.5 mm. in the seventh stage. Body 

 dark gray, paler below, legs flesh color. It 

 is marked as in O. badia. There is a pair of 

 plumed black pencils from wart ii on joint 2, 

 from wart v on joint 6 and a single one dor- 

 sally on joint 12; also a pair of simple white 

 pencils from wart v on joint 5, and in one 

 example an additional pair of black plumed 

 pencils from wart v on joint 7, distinct and 

 only a little shorter than the others. Some 

 short brown hair precedes the black pencil on 

 joint 12. Brush tufts yellowish white or 

 whitish brown, darker along the crest. 



Cocoon and pupa as in O. badia.

This can hardly be anything else than O. 

 leucostigma S. & A.f I have not seen the 



t Since the above went to the printer, I have examined 

 the figure of leucographa in the copy of the Zutrage in 

 the Harvard College library and find that it represents 

 O. leucostigma S. & A. The varietal name proposed by 

 Hv. Edwards for the form without the white spot, viz., 

 var. obliviosa, will stand as valid. It will prove that 

 this has been redescribed by Mr. Beutenmuller (Psyche, 

 v. 5, p. 300) as the only character for specific separation 

 between obliviosa and inornata is the difference be- 

 tween "yellow" and "orange" in the coloration of the 

 warts of the larvae.
