ADELOCEPHALA, Boisd. 



Adelocephala albolineata, n. s. (Plate 1, fig. 7, % .) 



I 'rimaries bright yellow finely mixed with dark scales and crossed 

 by two distinct white lines. The first of these runs from costa, above 

 the discal cell, inwardly obliquely to submedian nervure, whence it is 

 rounded to extreme base of the wing, nowhere touching internal 

 margin. A white spot at the lower extremity of the discal cell. The 

 second white stripe runs inwardly very obliquely from the apex to 

 internal margin, which latter it joins at within its middle, at a point 

 beneath the inner extremity of the discal cell. External and internal 

 margin bordered with white scales. 



Secondaries of a deep pink, of a more intense color on the disc and 

 along the basal half of internal luargin, which parts are covered with 

 longer scales than the rest of the wing. A black discal spot. A 

 continued, white, subterminal stripe, which does not run parallel with 

 the external margin of the wing, since it emanates at the apex and 

 joins internal margin much within anal angle. Costal and external 

 margins of a dull whitish shade. 



Under surface very pale, dull whitish, with a pink tinge, which is 

 very faint and evenly spread over the secondaries, but is brighter 

 over the primaries centrally, deepening especially on the disc where 

 the scjuammation is concolorous with upper surface of secondaries. 

 On the primaries, below the costa, centrally, are scattered bright 

 orange-yellow scales; a distinct black discal spot; the outer oblique 

 white stripe of the upper surface is here faintly reproduced. On the 

 secondaries a dark brown discal spot ; the subterminal white band of 

 the upper surface is here distinctly reproduced. Thorax, above, con- 

 colorous with upper surface of primaries, bright yellow; a whitish 

 stripe along the inner margin of the tegulae. Head, much sunk 

 beneath the elevated prothoracic pieces, which render it invisible from 

 above. Abdomen, yellow dorsally ; laterally and beneath, with under 

 thoracic surface, of a dull whitish pink tinge somewhat darker than 

 the under surface of the wings. 



Exp. % 2.50 inches. Length of body, 1.15 inch.

The individual of this species, that we have before us, is deprived 

 of its antennae. The species is very distinct from our more Northern 

 Adelocephala bicolor Grote, (JDryocampa bicolor Harris.) and may be 

 readily distinguished by its white lines, which are unusual. Sphingi- 

 campa distigma Walsh, and Dryocampa bicolor Walsh, are identical
