anticae linea discoidali, posticae punctis marginalibus nigrescentibus, lunulisque 

 subraarginalibus fulvis signata?. 



Alse subtus cinereas, linea discoidali, serieque punctorum quadran- 

 gularium albo marginatorum signatas. Luuularum series submarginalis duplex, 

 lunulas fulvas includens, in posticis intus triangulis albis suffulta. Lunulas 

 marginales in posticis metallice micant. 



Of this species I possess only one specimen ; but this differs so much from 

 the other California Lycasna?, that I consider myself justified in giving a 

 diagnosis of it, although, as a rule, descriptions of Lepidoptera belonging to 

 complicated and difficult groups should not be given without ample material on 

 which to base them. 



This specimen is from Mono Lake, and was collected by the Geological 

 Survey.

This species was collected at an elevation of eleven thousand feet, on the 

 head-waters of the San Joaquin River, by the Geological Survey. It repre- 

 sents the European L. Battus. 



16. L. Enoptes, Boisd. Hills near the Mission Dolores, and in the San 

 Bruno Hills. This species is rather rare. It represents the European L. Aegon. 



17.' L. Antccgon, Boisd. The most common species near San Francisco, 

 and found nearly everywhere through Central California. There are several 

 generations succeeding each other through the year. A specimen I received 

 from the head-waters of the San Joaquin River differs somewhat from this ; but 

 as I have only one of this variety, I will not venture to express a decided opin- 

 ion in regard to it. It is, perhaps, an Alpine variety, and corresponding with 

 a similar one of L. Sapiolus, of which I received several specimens forming a 

 series of transitions from the common type. 



18. There is a species approaching the European L. Agestis, and which I 

 received from the head-waters of the San Joaquin River ; but the specimens in 

 my possession are too imperfect to allow of an accurate description being given. 



19. L. Amyntula, Boisd. From the Contra Costa hills, where, in May and
