which Montana Verity from Hall Valley, Colo., is apparently a syn- 

 onym; this Colorado race can in our opinion scarcely be separated 

 from the Californian form. 



ANTHOCHARIS STELLA Edw. 



This form is characterized in the original description as having 

 the $ pale lemon yellow but the series in the Edwards Collection at 

 Pittsburgh is very varied, both white and yellow forms being labelled 

 Stella in Edwards' handwriting. A $ from Yosemite however agrees 

 with the description and is further labelled 'type' in red ink so we 

 would restrict the type to this specimen as the locality is mentioned 

 in the original description. We doubt if the form is constant. 



Callidryas eubule L. 



As stated in the Biologia (p. 141) Linne evidently described this 

 species from a 9 from Carolina and his sennae from a $ from 

 Jamaica. Butler, in his revision of the genus (Lep. Exot. p. 58) re- 

 gards them as two species and his figures are quite accurate; he sep- 

 arates them mainly on the heaviness of the purplish markings on the 

 underside in sennae as compared with eubule and the deeper tone of 

 the ground color. In a pair from Jamaica before us this is certainly 

 very evident, especially in the 9 sex. 



Typical eubule is the form with the 9 the same yellow color as 

 the $ and with the marginal dark spots confined generally to the ends 

 of the veins and not continuous; this form seems to be the only one 

 in Florida, judging by a long series before us from Palm Beach, 

 Chockoloskee, and Glenwood and extends northward through the 

 Eastern and Middle States. In Texas we meet with a 9 form which 

 has much heavier marginal markings and is either yellow in color 

 with the secondaries considerably tinted with orange or else a very 

 pale whitish ; in Arizona this latter seems to be the usual form. These 

 9 's approach very close to our Jamaica 9 of sennae; although the 

 ground color of the underside is rather paler, the maculation is just as 

 heavy; the pale 9 may be yamana Reak, but we do not know the 

 type nor where it may be found. In the $ sex the form can scarcely 

 be separated from typical eubule; in general the maculation is heavier 

 and some Arizona specimens agree exactly with our Jamaican $ ; 

 there is also a tendency for the discal spot on underside of primaries 

 to become decidedly larger and more figure-of-eight-shaped ; other
