black linear center; rudiments of tlie exterior lino in spots near tlie costa. 

 Median brauclies marked in black. Posterior wings, beneath, white, tinged 

 with ochreous. Costa and costal angle more conspicuously ochreous. Discal 

 dot round, black, distinct. Median line subobsolete, punctiform ; black atoms 

 border the costa and outer margin, accumulated at the costal angle.

This is the first species of Valeria which has been discovered 

 in North Amei'ica; it belongs to the same section of the genus as 

 the European V. oleagina ( W. V.), than which its wings are more 

 elongate, and antennae slightly less pectinated. Our species has a 

 marked bombyciform appearance, caused by the pectinated anten- 

 nae, the short, robust thorax and abdomen, the former thickly 

 clothed, and by the peculiar squaraation. It has also a superficial 

 resemblance to the common Iladena adjunda (Boisd.), caused by 

 the conspicuous white reniform and orbicular. 



I have dedicated this interesting species to my kind friend Mr. 

 A. R. Grote, to whom I am much indebted for aid in my ento- 

 mological work. 



Ablepliaron fuiuosuia, nov. sp. 



Palpi outwardly and legs inwardly concolorous with the breast, which is 

 blackish drab, tibiae and tarsi outwardly and the front lighter drab. Thorax 

 and anterior wings above dark shining brownish drab, the color slightly 

 increasing in depth from the base outwards. From the base beneath the me- 

 dian nervure there is a light linear shade extending one-third the length of 

 the cell. All the nervules are marked with lighter drab, particularly towards 

 their termination. The proximity of the costal branches gives the costal 

 margin an eyident lighter appearance. Posterior wings, above, uniform dark 

 shining drab ; wings beneath dark drab, nervules of both wings lighter, but 

 not so conspicuously so as on the anteriors above. Anteriors with the costal 

 margin, and a central shade proceeding from the base, of a brownish drab. A 

 diffused blackish spot at the termination of the cell. 



Expanse, 36 m. m. Length of lodij, 14 m. m. Ilaljitat, Massa- 

 chusetts. May 24th and 26th. Coll. H. K. Morrison. Closely 

 allied to A. Henrici, with which it agrees in form and structure. 



This species may, by the discovery of intermediate specimens, be 

 considered an abnormal variety of Henrici, but at present and until 

 further material is obtained, I am disposed to think it distinct, in 

 which opinion Mr. Grote concurs.
