'64 PIERI8 RAP.E. 



The very first \yor(l.s he says, after " Nov. Sp.," arc " Size and form of Pieris Hap<r, L." ! ! and well 

 could lie say so, for tlie one which he described as the V is the comiuou d' form of that species; the other is 

 also a d, with the dark apical patch of primaries represented hy a few scales only ; examples exactly like this 

 one I also have from Germany. 



But whenever I think of this comedy of errors, an uncontrollable desire overcomes me to lie back and in- 

 dulge in a o;lorions gufiiiw over the fallibility of ns poor humans, for in our beloved studies it is as Butler savs, 

 in Hudiliras, of religion, " still be doing, never done; as if religion were intended for nothing else but to be 

 mended." 



The two types of I'. Marginalis arc in Mus. Comp. Zool. at Cambridge; the d came from Crescent City, 

 Cal., and the V from Gulf of Georgia. 



The two types of P. Yreka are from California. 



There is a curious thing in connection with these western examples of Rapa?, (Marginalis and Yreka,) 

 that they should have bc<>n found in C'alifornia and Washington Territory four or five years before the species 

 was introduced into Canada an<l the Tnited States from Europe; this fact furnishes material for .some reflection. 



I trust my readers will forgive me right cheerfully for not going into elaborate griseous, luteous, cyaneous 

 de.scri|)tions of the.se c( mmon species; it may even be considered waste of time and material to have figured 

 them, but I have done so with the purpose that all might see for themselves that P. Marginalis and P. Yreka 

 are nothing but P. Ra|)ae, and P. Pallida, P. Castoria, and P. Venosa are but forms of P. Napi, and not have 

 tfl dejiend on my determinations alone. 



Fig. S illustrate- the curious n' variety of P. Rapa', first described by Mr. Scuddcr, under the name of 

 Novanglise,* in 1872, and which has no analogue in the old world; it is not of unfrequent occurrance, 

 and some of my friends inform nie that these yellow males are from larvse, which feed on Mignionette, but if 



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

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

 never yet seen or heard 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 Helichtaf does to C. Erate,| whatever 

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

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



thing found in the old country 



ANTHOCHARIS OLYMPIA. k<,wakl.s 



Trans. Am. Ent. Soc, Vol. Ill, ji. 266, (1871). 



(PLATE VIJI, FIG. 9, d.) 



Male. Exjiands 1-j inches. 



Body black above, beneath white. 



Upper surface white, with black at ba.se of all wings. Primaries have a black apical patch broken with 

 white ; a black di.scai spot. 



Secondaries with a small black spot on costa near the apex, and a minute black discal point. 



Under surface white. Primaries, a small yellowish grey spot on costa not far from the apex, also a few- 

 specks of greyish extend in a broken line from this spot to the exterior margin ; discal spot enclosing a white 

 line. 



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

 dian nervure by a cross-band ; on these greenish bands are a number of round, white dots. 



The female 1 have not yet had the opportunity of examining, but Mr. Edwards, in his description, says 

 It IS " similar to male." " tr > j

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

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

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