terior wings, largely maculate with black. A broad dorsal series of 

 black spots on the segments. A reduced lateral series of similar spots. 

 Underneath, all the segments are neatly banded with black anteriorly. 



Exp. % , 1.20 inch. Length of body, 0.50 inch. 



Habitat. — Nevada. Mr. J. Akhurst. 



Allied to A. blakei, Grote, from Colorado; the anterior wings are 

 less produced apically, the external margin less oblique. The broader 

 transverse bands on the anterior wings, the black caputal and thoracic 

 parts, and the absence of median spots on the secondaries sufficiently 

 separate this species from its congener. The habitus of Arctia neva- 

 densis, recalls that of certain European species of the genus. 



PARORGYIA, Packard. 

 With respect to the synonymy given by Dr. Packard, in his " Synop- 

 sis," of " Parorgyia achatina," there is an evident misconception. In 

 the first place it is clear that Sir J. E. Smith's Pludsena achatina is 

 not the species described in the " Synopsis." An examination of Ab- 

 bot's figure and a comparison of the description with that given by Dr. 

 Packard will at once show plenty of distinguishing characters. From 

 the figure and the remark, that " the black curved line running longi- 

 tudinally from the base towards the posterior angle of the wing is its 

 very distinguishing character," it is plain that Phalxna achatina Smith, 

 is a near ally of P. parallela nobis, while there are sufficient differences 

 to allow us to consider our Eastern species as distinct from the one 

 from Georgia. On the other hand Hubner figures " Orgyiu leuco- 

 phsea," in illustration of " Phalsena leucophxa Smith," but the species 

 is certainly not Abbot's as may be seen by a comparison of the two 

 Plates. Again, Hiibuer figures a species which he calls " Dasychira 

 vtdgaris Tephra" on the plate cited by Dr. Packard as represent- 

 ing " Dasychira achatina Hubner." This species (Dasychira tephra, 

 Walk.) better corresponds to Dr. Packard's description, without, how- 

 ever, coinciding. Whether the species described by Dr. Packard be 

 then Dasychira tephra Hubner sp. or not, we cannot decide, having no 

 specimens; it is, however, clear to us that neither correspond with Abbot's 

 figure. A % specimen in the collection of Mr. Walsh, which we have 

 no longer at hand, agreed with Dr. Packard's description, and has been 

 determined by Mr. Grote as " Parorgyia achatina Packard.'' We offer, 

 then, the following as the correct synonymy of Phalsena achatina Smith, 

 a species which, with Parorgyia leucophxa Packard (Dasychira leuco- 

 phxa Walk.. Phalxna leucophxa Smith ). will probably be re-discovcrcd 

 as soon as Southern specimens are received.
