tended delicately and sinuously to a fine point; interior linger long and slender, 

 tapering gently throughout, straight, excepting as it follows the curve of the clasp. 



Described from 12 <J 1$. 



Caterpillar. Last stage. Head light colored, the triangular suture dusky, the 

 bottom of tlie triangle fuscous, and all the sides, from the interior base of the summit 

 spine to the anterior portion of the ocellar liehl, and excepting a curved streak running 

 backwards above the ocellar field, blackish; summit spine entirely black, very stout'i 

 the spinules emitted about the middle, the basal portion half as long again as broad, the 

 spinules very stout, scarcely tapering, abruptly docked, not so long as the apical por- 

 tion, and diverging from it at an angle of about 30° to 40°, the main stem provided 

 with a few miniature spinules emitting rather long hairs ; other spiniform papillae 

 pale, the hairs also pale; mandibles very dark reddish. 



Body " light green, the dorsal and subdorsal rows of spines shining black, except at 

 base, which is rufous, with long branches; those of the anterior segments more 

 numerously branched than the others and having each point tipped with a seta ; the 

 super and substigmatal rows rufous, tipped with black. Length tAvo inches " (Lintuer). 



Chrysalis (83 :36, 44, 45) of a " beautiful green, delicately reticulated," the meso- 

 thoracic and first and second abdominal tubercles of the laterodorsal series " golden " 

 exteriorly and posteriorly ; mesonotal tubercle similar to that of P. comma and ridged 

 "with black anteriorly . . . stigmata brown with a brown spot beneath"; creraaster 

 " bordered with brown" (Lintner). Length 25.5 mm. ; height at mesonotal tubercle 

 !) mm. By Mr. Lintner's favor I have seen the skin of his original specimen. 



Distribution (20: 4). This butterfly, more properly a member of the 

 Canadian than of the Alleghanian fauna, occupies nevertheless nearly the 

 whole northern half of the latter, being reported from Iowa (Austin, Os- 

 born), northern Illinois "abundant" (Thomas), Wisconsin (Chamber- 

 lin. Hoy), southern Michigan "common " (Harrington), New Harmony, 

 Ind.,* (Boisduval-LeConte), Rockport, Poland and Cleveland, Ohio 

 (Kirtland, Kirkpatrick), Fredonia, N. Y. (Mark), Philadelphia "rare" 

 (Blake), Maryland "rare" (Uhler) and Long Island (Graef). A single 

 individual of what was probably this species (" polychloros ") is reported 

 by Jones as taken in Bermuda by Canon Tristramf. In the north this 

 species is generally very common throughout all the inhabited part of 

 Canada. It has even been found within the limits of the Arctic fauna, at 

 Okak in Labrador, whence it was brought by Dr. Packard, and specimens 



*This seems doulitful; for it may s«imply 

 have been received from Say. 



tit is also quoted in Sagra's Cu)»a among the 

 butterflies of that island, but so many other 

 l)utterflies foreign to Cu))a arc catalogued in 

 the same work, that its testimony is of little 

 value; yet there is a single worn specimen of 

 this species in the Museum of Comparative 

 Zoology, purporting to have been taken in 



Cul)a ))y Mr. Charles Wright; this liotanist 

 has certainly collected largely in the moun- 

 tains of Cuba, ))nt Dr. Gundlach has for years 

 devoted particular attention to the insects of 

 this island, collecting in every part of it with- 

 out meeting this Imtterfly. It seems, there- 

 fore, more probable that there has been some 

 error in the labelling of this specimen in the 

 Cambridi;e 3Iuseum.
