reddish-brown, with a lighter line at base. Hindwings fuscous-brown 

 with red-brown suffusion along termen. Cilia red-brown, with ochreous 

 line at base, and ochreous tips. Discoidal lunule shows faintly. 



?. Forewings ■ pale ochreous. Marks as in male, but slightly less 

 defined. Cilia lighter than in male. Hindwings lighter than in male. 



The underside of both sexes is well marked with a well - defined 

 reniform marking and discoidal lunule, also a well-defined line at about 

 § passing right across both wings. In both sexes varieties occur with 

 a strong fuscous suffusion from base above dorsum to near tornus, as 

 seen in some specimens of Morrisonia omoplaca. Specimens such as 

 these might be better to illustrate from, but apparently are not the 

 typical form. The fore wing of the moth being dark in colour, with 

 few determined markings, makes a poor illustration. 



Apparently close to rubescens, but more strongly crested, deeper in 

 colour in the $, lighter in colour in the $. The subterminal line in 

 rubescens is more deeply indented than in pascoei. 



The first specimen came to " sugar " at Orepuki, 1st September, 

 1910 (a $). In November of the same year- 1 took another at Queens- 

 town (<?), and this year Mr. M. 0. Pasco has been kind enough to send me 

 about twenty taken at " treacle " at Queenstown in October. As it is 

 through Mr. Pasco's kindness I have the chance of describing from such 

 a good series, I am naming the moth after him. 



The Larvae and Pupae of some New Zealand Butterflies. 



In Hudson's " New Zealand Moths and Butterflies " we have details 

 of the life-histories of most of our butterflies. The following additional 

 notes may prove of interest. Owing to inability to devote special time 

 to the larvae taken, the information here given is but scrappy and in- 

 complete. 



Chrysophanus boldenarum. 



This little butterfly appears to be commonest on the Canterbury river- 

 beds. It frequents patches of Donatia, flitting in dozens over the heated 

 shingle patches. The first specimens appear about October, and I have 

 taken it as late as March. 



On the 20th November, 1909, I found larvae and pupae of this butter- 

 fly under stones in the Makikihi River bed. I was successful in rearing 

 three. These all emerged on or close to the 18th December, 1909. In 

 November, 1910, I again 

 found the larvae at St. 

 Andrew's, Canterbury. 



A point which appears 

 to me of great interest was 

 that in each case the larvae Larva, 



and pupae were under Chuysophanus boldenakum. 



stones that also sheltered 

 ants' nests, and at least two of the chrysalids had ants running over them 

 when I lifted the stone. Both these chrysalids produced butterflies. As 

 certain of the Lycaenidae in other countries have been taken in conjunction 

 with ants, this point in connection with one of our New Zealand butter- 

 flies promises to be worth investigating.
