NEOPHASIA. 
NEOPHASIA MEN APT A. 1—3. 
Neophasia Menapia, (Pieris) Felder, Weiner Ent. Monats. Ill, p. 271, 1859. Pieris Tau, 
Scudder, Proc. Bost. Soc. Nat. Hist. 1861. Ninonia, Bois. Lep. de la Cal. 1869. 
Male. Expands 2 inches. 
Upper side white with a faint pink tinge ; costal margin of primaries partly bor- 
dered from base by a black band which curves downward at extremity covering the 
arc ; apical border black, sinuate within, enclosing from three to five subovate white 
spots, and terminating abruptly on second median nervule ; fringes white. 
Under side white, the markings of upper surface repeated ; the apical spots 
enlarged ; the nervures of secondaries narrowly edged by black scales, and crossed 
by a submarginal black stripe not always complete. 
Body black covered above with white hairs ; beneath, thorax white, abdomen 
yellowish; legs black and white; palpi same; antennae black; club black, tip pale 
fulvous. 
Female. Expands 2.2 inches. Similar to male. 
This fine species is as yet rare in collections. According to Felder it is found 
in Utah. Boisduval describes it as coming from eastern California ; and Mr. 
Scudder as found abundantly at Gulf of Georgia. Although Felder’s description 
was published in 1859 and translated in Morris’s Synopsis in 1862, none of our col- 
lectors suspected the identity of the species with Tau, Scudder, or Ninonia, Bois. 
till 1870 and after the Synopsis of the Pieridse in this work had been published. 
Dr. Behr, in 1869, Trans. Am. Ent. Soc. erected for the present and an allied 
species the new genus Neophasia, between Pontia and Pieris, “differing from 
the former by the shape of the wing, and from the latter by its gauze-like 
substance, by the shape and proportions of the head and the slenderness of the 
thorax and abdomen.” According to Dr. Behr, both these species are found in- 
habiting the pine forest region of the mountain chains parallel to the coast of the 
Pacific, and he agrees with Mr. Lorquin in the opinion that the larvae feed on 
some coniferous tree ; “an unusual food for a Pieris, but not unknown in the case 
of certain Australian species.”
