(54 PIERIS RAP^. 



'I'hc very first words lie says, aftor " Xov. 8p.," arc "Size and form of Pieris Rap<v, L." ! ! and well 

 could he sa}' so, for the inic which he described as the V is the comiuon 'f form of that species; the other is 

 also a r?', with the dark :i|ii(:il patch of primaries represented hy a few scales only ; examjiles exactly like this 

 one I also liave from (Icnnaiiy. 



But whenever I think of this conicciy (it'errors, an iineontrollahie desire overcomes me to lie back and in- 

 dnlirc in a glorious i,niffa\v over the tiiliibility of ns poor humans, for in our beloved studies it is as Butler says, 

 in Ilndibras, of reiiirion, " still be dointr, never done ; as if religion were intended for tiothing else but to be 

 mended." 



The two types of I'. Marginalis arc in Mus. C'omp. Zool. at (Janibridge ; the ^ came from Crescent City, 

 Cal., an<l the + from Gulf of (ieorgia. 



Tlic two types (i( P. Yreka are from California. 



Tlicrc is a curious thing in connection with these western examples of Rapse, (Marginalis and Yreka,) 

 that tiicy sliDuhi have been found in California and Washington Territory fiuir or five years before the species 

 was introduced into Canada and the United States from Europe; this fact furnishes material for .some reflection. 



I trn.-i my readers will forgive me right cheerfully for not going into elaborate griseous, luteous, cyaneous 

 descriptiiius of the.-ic e( mmon species; it ncay even he considered waste of time and material to have figured 

 thciii, l)Ut 1 iiavc ilone so with the purpose that all might see for them.selves that P. Marginalis and ]'. Yreka 

 are nothiui; but 1'. Hapac, and i\ Pallida, P. Castoria, and P. ^'enosa are but forms of P. Xai)i, aud not have 

 to depend on my determinations alone. 



Fig. 8 illustrates the curious cf variety of P. Ra|)a', first descril)ed by Mr. Scudder, under the name of 

 Novangliie,* in 1.S72, and which has no analogue in the oUl world; it is not of unfrcipient occurrance, 

 and some ol uiy friends inform me that these yellow males are from Iarv;e, which feed on Mignionctte, but if 

 that be the case, why arc the females produced from larvae feeding on that plant not likewise lemon yellow, 

 or do only the male larvae aileet that food, perhaps there may be females of like yellow colour, Itut I have 

 never yet seen or licarr! of any such, all that have come under my observation were males, and I am of the 

 opinion that they bear to the normal form, the same relation that Colias Heliehtaf does to C. Erate,| whatever 

 that relation may be. lint it is really wonderful that within the few years that have elapsed since the time 

 of P. Rapae's introduction from Europe, there should have ari.sen a variety which is so entirely unlike any- 

 thing found in the old country.

Mai.k. E.\|)ands If inches. 



Body black above, l)eneath white. 



Upjier .surfiice white, with black at base of all wings. Primaries have a black apical patch broken with 

 white ; a black discal spot. 



Secondaries with a small black spot on costa near the a])c.x, and a minute black di.scal point. 



lJtnlcr surfiice white. Primaries, a small yellowish grey s])ot on costa not far from the apex, also a few 

 specks of greyish c.\tend in a broken line from this spot to the exterior margin ; discal spot enclosing a white 

 line. 



Secondaries with three irregular bands of greenish grey, the second and third ones connected on the me- 

 dian ncrvnrc by a cro.ss-i)and ; on these greenish bands are a number of round, white dots. 



The female 1 have not yet had the op])ortunity of examining, but Mr. Edwards, in his description, says 

 it is " similar to male."

This fine insect is distinct both in form and ornamentation from ail other known American species of 

 Anthocharis ; though smaller, it forcibly reminds us ot the beautiful Zegris Eupheme§ of Ru.ssia and Syria, 

 the markings of under side of secondaries bear a wonderful resemblance to those of that species, as does also
