names quinquefasciata and viridata with this species; viridaia is ahnost 

 certainly correctly applied and if it be found that the former name 

 should be transferred to fiircata will then be the proper one to use for 

 this species. Through the kindness of Mr. S. Henshaw of the Cam- 

 bridge Museum we have received photographs of the types of these two 

 species which we publish on Plate \l Figs. 10, 11 ; the name qmiiquc- 

 fasciata we apply to the form with rather clear well-defined bands com- 

 parable to the form fuscoundata of fiircata; ziiidata is greener and 

 much more suffused and indistinct in maculation and without the ruddy 

 shades of the former form.

Even a casual glance at the Uncus of this species shows that it 

 has nothing whatever to do with fuicata as listed by Mr. Swett; in 

 common with rcflata Grt. and cochizcata Swett it has a conical Uncus 

 with narrow truncate apex ; the latter form shows distinctions in tlie 

 penis armature from albifasciata and is therefore a distinct species, but 

 the former is practically identical in genitalia and we consider that the 

 name reflate can only be used in a varietal sense for the Arizona race of 

 a species which on account of the law of priority must bear the name 

 albifasciata Pack, although evidently the nimotypical form is an aber- 

 rant one. 



The species is easily separable from fiircata by the form of the 

 postmedian band which is narrow, sharply angled inwardly at the cell 

 and then bulging outwardly; Mr. Swett is mistaken in stating (C. Ent. 

 XLIII, 78) that this cone-shaped projection (as he calls it) is not 

 found in albifasciata, for Packard's figure of the type distinctly shows 

 it ; the pale patch in the subterminal band is smaller, whiter and is sit- 

 uated between veins 4 and 5 (not veins 3 and 4 as in fiircata) with 

 frequently a short tail crossing into the space between veins 3 and 4. 

 As already stated the nimotypical form with white median band as 

 figured by Packard (Monog. PI. VIII, Fig. 34) is rare; reseda Swett 

 is clearly referable to this species and represents a form suffused with 

 ruddy; in his description Mr. Swett mentions particularly the white 

 tailed spot in the subterminal band; the early date of capture (Feb.) 

 also points to this species. We have before us a form from Sonoma 

 and Alameda Cos., Calif., which appears to be much more of tlie normal 

 form in California than any of those forms to which names have
