the surface, in a very coarse, irresular reticulation, in wliicli may witli dilliculty lie 

 recognized a ceuti-al, iufralateral series of roundish spots, and a postero-central, 

 .suprastigmatal scries of similar spots !j;ro^vini: sonle^vllat ol)scurc posteriorly; and 

 sometimes a macular, infrastiiimatal stripe; stiijmiita liriirlil luteons, the lips white. 

 Tlie network of interlacinir riilges is concoloro\i> with the ground, the ridges distinct 

 but delicate, low and equal, forming tolerably large cells, the lloor of which is minutely 

 punctate, the punctae ovate. Tlie sparse, dark brown pile consists of hairs which are 

 less than a third as long as the abdominal segments, tipped with blackish fuscous, 

 minutely spiculiferous, and seated on very inconspicuous papillae. Spiracles testa- 

 ceous, with white lips. Length. 9 mm.; breadth in middle of tliorax, 3.1 mm.; In 

 middle of abdomen, 4.75 mm. ; height of thorax, 3 mm. ; of abdomen, 4. .5 mm. 



Distribution (23: 7). Tliis hutterHy is a menihcr of hotli the Caroli- 

 niiin and Alleglianian taiinas, bcinsr tbimd in all the Atlantic state.s from 

 northern Florida to Massachusetts. We know very little of its western 

 extension as it has been seldom expressly recorded, but as it is found in the 

 south as far west as nortlnvestorn Texas and in the north to Dakota (Mor- 

 rison), it probably everywiiere extends to the Great Plains. Worthing- 

 ton says it occurs in Illinois. .Saunders records it from Point Pelee in 

 southern Ontario, and Dimmock took it at Cumberland Gap, Kentucky. 



In Xew England it occurs only in the southern portions and seldom in 

 any great abundance. Its most northern known locality is the vicinity of 

 Boston where it has been taken in West Roxbury, Hyde Park and Dor- 

 chester "quite abimdant" (Faxon), Lynn (ISIcrrill), Quincy (P. S. 

 Sprague), AVyoming (Morrison), Cami)ridgc anil Alilton (Harris), Blue 

 Hill (F. H. Sprague) and Walpole, ]\Iass. (Guild). It has also been 

 found at Springfield (Emery), Mt. Tom (Dimmock), Holyoke Range 

 (Parker) and Holyoke, Mass. (Stebbins) ; and at New Britain (Dim- 

 mock, Hulbert. .Scudder), Guilford (Smyth — Yale Coll. Mus.), Farming- 

 ton (Norton) and New Haven, Conn, "'abundant" (Verrill, Smith. 

 Harger — Mus. Yale Coll.). 



Haunts. The butterfly ma}' be found about red cedars and will hardly 

 be found where these do not occur. The imder surface of the wings of 

 the butterfly so closely resembles the color of the leaves of the red cedar 

 that when it has once alighted upon this tree one can only disco\er it by 

 jarring the trunk and startling it again to flight. 



Oviposition. The eggn are laid near the tips of the blossoming twigs 

 of red cedar, a large number being found I)y ISIr. Hidbert and myself on 

 these spots, while the less forward twigs vs-ere sought in vain for a single 

 egg. They were generally tucked in or near the chinks of the overlap- 

 ping scales but sometimes with no attempt at concealment. 



The female lays with wings erect, first rubbing together the hind wings 

 slowly for a time, then raj>idly, immediately after which she hedges aliout 

 as if to get into a good position, extends and lowers iier abdomen, deposits 

 the Ggg, withdraws the abdomen and then flics away. The sight of the 

 process suggested that perhaps the rubbing of the wings may here be the
