Still another extreme form of the typical defensaria Gn. 

 remains without a name, and I propose to describe it as follows: — 

 Xanthorhoe defensaria Gn.,var. conciliaria, var. nov. 



Expanse 23-25 mm. Wing pattern same as xnnovxwdA defensaria 

 Gn. except that the bands are a very deep reddish chocolate, 

 the fore wings are basally yellowish and the outer margin is a 

 reddish yellow or ochre. This yellow, suffused variety corre- 

 sponds to the yellow variety of mnnitata, (Jiethlandica Prout). 

 Doubtless this variation occurs in most of the Cidaria group 

 allied to mnnitata Hiib. Tht white^anded spring form also 

 shows this \ariation, but I think it docs not differ sufiftciently 

 from conciliaria to receive a separate name. The dark-red, central 

 band is lighter than normal and the wavy lines of the outer margin 

 are present, but are reddish instead of fuscous. 



This variety is very distinct. I have it only from Victoria, 

 B C., though no doubt if is common in Alaska. In some specimens 

 the outer margin is entirely ochreous without markings exqept 

 the marginal white line and two marginal white dots opposite 

 the angle of the extradiscal line.

There is a possible third brood which is found in the late fall 

 up to October 1st. This is very small and stunted, and there is a 

 tendency for the median band to be very narrow. The central 

 band is of the same colour as in the normal male but is more solid 

 and less distinct. This form is certainlv worthy of a name and 

 may be described as follows: — 

 Xanthorhoe defensaria Gn. var. thanataria, var. nov. 



Expanse 18-20 mm. The bands are of the same shape as in 

 the normal form but tend to be very narrow. Basally the male is 

 pale ashen without lines, the central band dark and almost solid, 

 in some specimens showing irregular lines. Outer margin very
