1620 THE BUT'J'KKFLIES OF NEW ENGLAND. 



equal ^vhen of full size, sometimes reduced nearly to dots. Just before tlie tip of 

 the cell tliere is usually a doulile spot, the lower part smaller and sometimes ol)so- 

 lete; and in the medio-submedian interspace, below the lower median spot, there is a 

 pale clouding whicli sometimes is developed to a double spot, the lower portion ex- 

 tending fnrtlier toward the base than the upper. Fringe brownisli olivaceous, witli 

 dusky lines running through it, not so dark below. Hind win/js with the markings of 

 tlie normal type reproduced with a greater or less degree of faintne.ss l^y scattered, 

 dull, tawny scales on a brownish base, sliglitly paler than tlie ground color of tlie 

 wing. Fringe as in fore wings. 



Beneath, fore loings bi-own, Ijlackish toward the base, tlie middle of the wing more 

 or less largely sullused with brownish yellow; the whitish or yellowish spots of the 

 upper surface are repeated, those of the lowermedian and medio-submedian interspaces 

 usually merged into a large, common, irregular, pale patch; above the middle median 

 nervule the outer margin is besprinkled with pale bluish or hoary scales; the trans- 

 verse black streak at the tip of the cell is indistinctly present. Jlind loinrjs very 

 dark, chocolate brown, the baud of the normal type present only as a slightly lighter 

 field often sparsely besprinkled with a few very pale blue, elongate scales, such as 

 give a hoary appearance to the apical half of the outer border, beyond the great 

 transverse belt. Fringe of both fore and liind wings much as above, but sliglitly 

 paler. Described from thirty -one specimens. 



Egg (66:18). Surface of cells each with from 15-25 very minute punctuations; 

 average cells measuring .0085 by .0127 mffi. ; extremes of micropylic canals distant 

 .004 mm. from each other. Cells bordering them (69 :10) .0047 by .0094 mm. ; outer 

 cells of micropylc from .0113 to .0132 nun. in diameter. Color pale green. Height, 

 .74 mm. ; width, .95 mm. 



Edwards is altogether mistaken in saying (Can. ent., xvi:110) that this egg is 

 ribbed like a melon. 



Caterpillar. First stage. Head (80:54) black, shining, smooth, with p.ale hair.s 

 .08 mm. long, infrequent, Inserted in shallow punctures; ocelli and mouth parts black; 

 basal joint of antennae pale, third dusky, last pale; palpi pale fuscous; antennal 

 bristle apparently arising from near tip of dusky joint, .14 mm. long. Body pallid, 

 posteriorly tinged with lemon yellow ; hairs pale, slightly fuscous at tip, not taper- 

 ing and scarcely swollen at the tip, vertical, .08 mm. long. The last segment 

 contains two pairs of long, recurved, bristly, subdorsal hairs .37 mm. long, and in ad- 

 dition along the hinder edge four others, directed backward but not nearly so long; 

 fir.st thoracic segment with a narrow, black, shining shield, .045 mm. in breadth, situ- 

 ated on the anterior portion of the segment, bearing, anterioi-ly .at least, six hairs in a 

 row, posteriorly two lateral ones; there are two colorless papillae, one above the 

 other, in the middle of the sides of the second and third thoracic segments ; spiracles 

 concolorous; legs and prolegs white, claws slightly fuscous. Length, 2.32 mm.; 

 breadth of head, .57 mm. ; of body, .42 mm. 



Second stage. Head smoky castaneous, the posterior rim and ocellar field picoous, 

 minutely scabrous, hairs pale. Mouth parts testaceous, the edge of the mandibles 

 black. Body grass green above, much paler below, the last three or four segments 

 tinged al)ove with pale brown ; sprinkled rather profusely with dusky raised points, 

 each bearing a short blackish hair, not so long as the sliortest of the sections into 

 which the segments are divided; first segment livid; the thoracic shield brownish 

 piceous;legs and prolegs of the pale green color of the under surface; spiracles 

 forming luteous, circular annuli; there is a pale dorsal stripe, in the middle of wliich 

 the darker dorsal vessel can be seen In action; skin very transparent, allowing internal 

 organs to be seen. Length, 7 mm. ; breadth, 1 mm. ; of head, .75 mm. 



Third stage. Head varying from brownish red or ferruginous to a very dark black- 

 ish green, minutely scabrous ; month parts dark ferrnginons, the mandibles edged with 

 black ; ocelli blackish ; antennae pale reddish. Body mottled in about equal measure 

 with dark grassy green and pale ilnll yellowish, darker in the middle of the body, very 

 faintly tinged posteriorly with reddish; specked profusely witli l)lack or blackish
