Arizona and Texan $ 's from the same localities cannot be separated 

 from $ 's from Florida or the Eastern States ; it is quite possible that 

 the variation is seasonal as we have noticed in the little dated material 

 we possess, that the most heavily marked forms have all been cap- 

 tured in September whilst those from the same region (Huachuca 

 Mts.) taken in July are all more lightly marked. Careful breeding 

 will be necessary to settle the number of generations of this species 

 in the south and the possible variation between the various genera- 

 tions as well as in each generation, nothing definite having to our 

 knowledge ever been published on this subject. We think in view of 

 the fact that Florida 9 's vary so constantly and markedly from the 

 western 9 's that the name sentiae, which, in sens strict, is only appli- 

 cable to the Jamaican race, might for the present with a fair degree 

 of accuracy be applied to the race of eubule from Southern Texas 

 and Arizona. It would be interesting to learn from what further 

 localities the sennac form of 9 is known. 



Kricogonia lyside Godt. 



After careful examination of a very long series from Browns- 

 ville, Texas, we have come to the conclusion that this is an extremely 

 variable species and that the various names included as species under 

 this genus are in reality merely 3 or ? forms. 



Typical lyside is the form with deep yellow base to primaries and 

 no maculation with the exception of a small black streak at base of 

 inner margin on primaries in the $ ; terissa Luc. is the form with a 

 black streak from costal margin of secondaries % across the wing; 

 although Lucas mentions the 9 sex we have only seen $ 's and im- 

 agine it is a male form entirely ; Aaron calls this the summer form 

 (Pap. IV, 174) but all our dates of capture are March which would 

 rather point to its being a spring form; it is figured by Holland (PI. 

 34, Fig. 20) as lyside. Fantasia Butl. is a 9 form with smoky apex 

 of primaries, the ground color varying from white to yellow ; the base 

 of the wing is generally not noticeably yellow ; this form intergrades 

 with another 9 form, imicolor G. & S., which is entirely immaculate 

 yellow, and which has been redescribed and figured (PI. 26d) as xan- 

 thopsia by Rober in Seitz Macrolepidoptera. 



Lattice Lint, was a mixture of two forms; the $ as stated by 

 Aaron (1. c. p. 174) is evidently lyside Godt. and the 9 belongs to
