Hybrid Ceanothi-Gloveri. — Although Gloveri moths refused to pair 



among themselves, I had several crossings between Gloveri, ceanothi and 



cecropia. The ova obtained from a long pairing of ceanothi % with Gloveri 



$ were the only ones which were fertile. Unfortunately the larvse bred 



on Willow and Plum died, some reaching the third stage like ceanothi. 



The pairing of ceanothi and Gloveri was from the evening of the 20th 

 to the evening of the 21st of May. 'The larvae hatched from the 15th to 

 the 21st of June, the majority having hatched on the 16th and 17th. 



First stage — Larger larva?, black ; smaller ones follow, the colors 

 becoming of a more uniform hue as the larvae increased in size. They 

 looked like cecropia larvae. 



Second stage — Larvae yellow, with black tubercles ; head black. 



Third stage — Back bluish, sides yellow ; tubercles on back orange-red, 

 tubercles on the sides blue ; head yellow. 



Eight larvae, the produce of a pairing of female Saturnia Pyri with 

 unknown Samia (the pairing was not seen), lived seven days on Plum ; 

 they were bright yellow with a dark ring round each segment. 



The other crossings obtained were: June 12th and 13th, ceanothi % 

 and cecropia £ ; June 15th, Gloveri °. and cecropia £ ; June 18th and 

 19th, cecropia % and ceanothi $. In all the above cases the ova were 

 infertile.

On June 7th, 1879, I obtained some eggs from a $ captured the day 

 before. The eggs were smooth, pale green, spherical in shape and rk inch 

 in diameter. The eggs hatched on the 12th. Larva }i inch long, pale 

 green, largest at middle of the body and tapering slightly towards both 

 ends. Head slightly bilobed, of a faint brownish color, with a dark brown 

 spot on each side. The first segment has three minute brown tubercles 

 on each side of the dorsal line, and a large oval, though but slightly 

 elevated, dark brown tubercle on the dorsal line. The remaining seg- 

 ments have no tubercle on the dorsal line, but the second, third and
