350 THE CANADIAN ENTOMOLOGIST 



specimens, including those of my own collection, that of Mr. 

 E. H. Blackmore, the Museum of Comparative Zoology, Cam- 

 bridge, Mass., and the American Museum of Natural History, New 

 York^ — is the mals with a dark, greyish outer border on the fore 

 wings ard a rather indistinct, brownish median band, beyond which 

 are rows of triple dots on the veins, with traces of wavy lines. 

 The female differs from the male in that the l)and is of a solid, 

 dark, reddish-chocolate colour, the outer border is dark fuscous 

 gra\-, and the hind wings are darker basally and have several 

 undulating lines but not so many as the fore w'ings. When these 

 wavy lines are rubbed they show onK- as points on the veins, 

 and it was doubtless a rubbed specimen that formed the basis 

 of Guenee's description. Both the male and the female belong 

 to what I term the normal summer form, occurring from July 3 

 to August 30, according to my series. 



XaKlhorhde defeusaria in all its forms can be separated from 

 convallaria in that the basal line of the latter has a very strong, 

 regular, outward curve, where in defensaria it runs almost straight, 

 in a more or less shaded line, to the inner margin. They average 

 between 20 and 25 mm. in expanse in my series, only one or two 

 measuring below 20 mm. and about the same number over 25 

 mm., but none above 27 mm. 



I think this typical, normal, summer form with the gray 

 outer margin can be readily recognized by this description. I 

 have specimens of it from British Columbia and California. This 

 t\pical form represents the second brood, there being an early 

 spring brood which I shall discuss later. There are several varietal 

 forms of the summer brood. Packard (Proc. Boston Soc. Nat. 

 Hist., vol. XlII, p. 398, 1871) describes " Xanthorhoe (Coremia) 

 calif or niata, one female. Edwards, from California" as new. In 

 the material studied there is a specimen bearing this label and a 

 small, round, punch label, "No. .138.')." Beneath this on a large 

 label is written "figured in Monog." in Packard's handwriting. 

 This is undoubtedly Edwards' female, from California, and is 

 not a variety of miinitata Hiib., but of defensaria Guen. (See 

 Packard's Monograph, p. 137, 1876). He evidently mixed munitata 

 Hiib. and defensaria together, as he remarks on the peculiarities 

 of the Labrador specimens. The specimen of californiata Pack.
