the diffuse white longitudinal bands, which become obsolete anteriorly. 

 The stigniatal band extends down below the spiracles and contrasts 

 the black subventral tubercles. Its central part represents the inter- 

 segmental, substigmatal white patches of octomaculata, though the 

 marking is here quite undefined. Posteriorly the white bands tend to 

 usurp the whole ground area, showing the origin of the white ground 

 in octotnaculata. 



Nearly two years ago, Mr. Lembert sent me an egg of A. 

 mariposa (or possibly A. Ridingsii). The following is its appearance 

 under the microscope: — Flattened, round, strongly depressed centrally 

 at the micropyle. Rather less than forty deep grooves run vertically, 

 a few not reaching the summit; the edges of these grooves are some- 

 what sinuate, as if formed of rows of large pits which had become 

 confluent in a vertical direction. In a rather large area around the 

 micropyle, the grooves cease and are replaced by closely crowded 

 punctures, but not small, with sharply elevated rims. Diameter, .7 

 mm. Height about .2 mm. Base flattened. 



ACTIAS LUNA. 



On 24th May Mr. Lachlan Gibb took a female, which he left alive to 



get eggs, a number of which were laid between the 25th and 29th. On 



the 14th June the eggs were hatching, and the larvae were offered butternut 



leaves, which they eat readily, and matured very rapidly. About the 27th 



of the month, Mr. Gibb kindly gave me four of these larvae, which were 



then apparently more than half grown. They moulted once only, so far 



as my observations went, after I received them, and on 1 2th July three 



spun their cocoons, the fourth doing this on the i6th. Early in August 



Mr. Gibb asked me to take charge of his cocoons, and keep them with 



mine, as giving a better opportunity of getting another lot of eggs next 



season, and on 20th August I was surprised to find that one of Mr. Gibb's 



cocoons had disclosed the imago, a $ . Thinking that this was only the 



forerunner of others, I kept it alive, taking all the cocoons down with me 



to Murray Bay, but no other emergence took place. 



Mr. Street, jr., of this city, has since informed me that he saw a 

 specimen on our mountain at about the same time as this one emerged.
