122 THE ENTOMOLOGIST. 



in the second stage it is of a lighter red, without the black band; 

 in the other three stages it is green, with bright yellow tubercles. 

 A. Luna is green in all its stages, the colour in first stage being 

 very light green, almost white; the tubercles are of various 

 shades of red or crimson. The A. Luna moths emerged from the 

 beginning till about the end of June. The larva feeds well on 

 walnut, hazel, and other trees. 



Of Samia Ceanothi, from California, I obtained two pairings, 

 but was not successful with the rearing of the larvse. One of ray 

 German correspondents, however, succeeded, with only six eggs 

 of this species, in obtaining three cocoons, which I consider a 

 very great success. ^S". Ceanothi, in the perfect state, is a little 

 smaller than S. Gloveri, and of uniform colour on the four wings ; 

 rich brown, with white bands and markings. S. Gloveri seems to 

 partake of Ceanothi and Cecroina, but the cocoon of Ceanothi is 

 entirely different from those of Gloveri and Cccropia ; it is pear- 

 shaped, and very pointed at the open end. The interior cocoon, 

 of a brown colour, is small comjiared to the exterior envelope, 

 which is iron-grey. Most of the Ceanothi larvse I obtained died 

 in the first two stages ; a few reached the third stage, and were 

 thus : — Back of body sky-blue ; sides greenish yellow ; tubercles 

 golden yellow all along the back, and on the sides blue ; head 

 green. 



Ceanothi- Gloveri hybrid. — Many pairings took place among 

 different species, the ova being in all cases unfertile, ex- 

 cepting that of a cross between female Ceanothi with Gloveri, 

 which lasted from the evening of the 20th to that of the 21st 

 May, 1880. Over two hundred larvae hatched from the IStli to 

 the 21st June. Unfortunately they all died in first or second 

 stage, a few reaching the third stage. In the third stage the 

 larvae were thus : — Back bluish ; sides yellow; tubercles on back 

 orange-red ; tubercles on sides blue ; head yellow. One of my 

 American correspondents succeeded in obtaining cocoons of a 

 hybrid between Ceanothi and Cecropia. 



In 1880 the cocoons of Gloveri were very bad, and I obtained 

 from my large stock a swarm of cripples, and many pupse were 

 dead. This year (1881), on the contrary, the Gloveri cocoons are 

 both larger and heavier, and the stock I have promises to give 

 chances of success for the rearing of this fine species in England 

 and on the Continent. These cocoons, in 1880 and 1881, were
