The Synonymy and Habits of Pseudohazis eglanterina Boisd. 



Dyar, in a footnote to his description of the preparatory stages of Pseudohazis 

 shastaensis,^ remarks, "The common form of Pseudohazis with purphsh fore wings 

 has, strictly, never been described. Boisduval says of eglanterina 'alae anticae 

 albidocarneae,' which apphes to the form described as arizonensis by Strecker. 

 Behren's shastaensis was described from very black examples of the purple winged 

 form, so this name will retain. The form is constant, and has as good right to speci- 

 fic recognition as any species in the genus." The species of Pseudohazis commonly 

 found in California, and plentiful in this valley, I had considered as eglanterina 

 Boisd., but recently I sent a specimen to Dr. Dyar and he pronounced it shastaensis 

 Behrens. In fact, the eggs for his life- history of shastaensis came from Watson ville 

 in this valley. He also gives Yosemite, Monterey County and Portland, Oregon, 

 as localities in which shastaensis occurs and in his list of the lepidoptera of North 

 America (Bull. 52, U. S. Nat. Mus.), he gives Rocky Mts. to Arizona as the habitat 

 for eglanterina and Pacific States and Colorado for shastaensis. The only distinc- 

 tion between the two, so far as known to me, is that shastaensis has a more or less 

 pronounced purplish tinge to the wings. Behren's types were very heavily marked 

 specimens. Strecker^ writes, "The best known and by far the commonest is the 

 Calif ornian form eglanterina; it is very variable in the black markings; in some 

 instances being almost as heavily blacked as the variety of P. hera, in others it is 

 scarcely more so than in P. nuttalli 9 ; nor is this diminution of the black confined 

 to the females only as I have males w^ith as little black on as any female I have yet 

 seen, and even less. An extreme case in point is the male aberration (fig. 9) in 

 which the black marks are almost totally obliterated on both surfaces. Though 

 the upper surface of primaries is more generally flesh colored or pinkish, this is not 

 always the case, as I have seen and possess examples of both sexes in which the 

 primaries are the same yellow color as the secondaries, and others in which part are 

 yellow and part flesh colored." 



Mr. J. G. Grundel, who has collected by the hundreds the Pseudohazis found 

 here, tells me it is quite distinct from Mt. Shasta specimens which he considers typical
