white-fringed allies by the pure brown color of the marginal area 

 of primaries, with no dusting of white, and by the conspicuous 

 extra-discal band and its whitish servated edging. 



Thanaos Clitus. 



Male. — Expands from 1.5 to 1.7 inch. 



Upper side of primaries umber-brown, so much dusted with 

 whitish scales and clothed with white hair as to discover the 

 ground color only in small patches, as along the hind margin, 

 and also a little within the margin and on basal area ; the usual 

 extra-discal spots are black, on the upper half the wing long, 

 acute, below broad, lanceolate ; on middle of disk a broad, 

 black cross-band, reaching inner margin, and the basal area is 

 mottled with black; a clear brown, but not well defined patch, at 

 end of cell; on costal margin four sub-apical diaphanous dots, 

 three in straight line, the fourth a little inside ; a similar dot in 

 upper median interspace, and one at the end of cell. Secondaries 

 uniform black-brown ; fringes of primaries black-brown, of 

 secondaries white, cinereous at outer angle. 



On under side the spots are repeated, a little enlarged ; 

 primaries have a marginal row of white points, sometimes meet- 

 ing ; also an extra-discal series of light-brown patches more or 

 less dusted with white scales ; in some examples, however, these 

 also are wanting, unless next inner margin, and the whole limb is 

 thinly dusted white, through which runs a submarginal series of 

 brown patches ; in all cases there are many white scales over 

 apical area. 



Secondaries immaculate, except for a few whitish points 

 along posterior part of hind margin, which sometimes are de- 

 veloped into a white macular band. 



Body above black-brown, thorax and abdomen beneath grey- 

 brown ; legs dark brown, with ferrginous hairs on under side ; 

 palpi dark brown, the tips of the hairs whitish ; antennae black, 

 on under side slightly annulated white ; club black above, 

 ferruginous below and at tip.

NOTES ON LETIDOPTEROUS LARVAE. 



By a. S. Packard, Jr., M.D. 

 The following larvae were collected during the past season in 

 Maine, while engaged in collecting material for a revised and 

 enlarged edition of Bulletin No. 7 of the U. S. Entomological 

 Commission (Insects injurious to Shade and Forest Trees), 

 which is to form the Fifth Report ot the Commission to be 

 prepared under the direction of the Commissions of Agriculture. 

 The writer would here ask aid from lepidopterists in the way of 

 specimens and notes concerning any insects found on any kind
