230 THE BUTTERFLIES OF THE WEST COAST 



391. Lycaena Echo. Not elsewhere ilhistrated.

Echo is a variety of Piasus, showing a series of dots on outer 



margin of hind wings. The female only has this variation ; it is 



not a seasonal form, but appears at any time during the flight of 



the species. 



392. Lycaena Arizonensis. Not elsewhere illustrated.

 This is another and possibly a climatic variation of Piasus, con- 

 sisting mainly in the increased duskiness of both fore and hind 

 wings, and, so far as my observation extends, in the presence of 

 the Echo-like ocelli on hind wing in every instance. This form is 

 found in the hilly or mountainous parts of southern Arizona. 



393. Lycaena Monica. 

 No figTire. 



In 1866 a small tailed Lycsena from southern California was 

 named, and later was figured by Strecker, the figure looking like 

 a small-sized male Amyntula, with two small black dots on the 

 wing just above the tail, the tail thread-like, similar to the tail of 

 some Thecla. Since those early days no one has seen Monica, and 

 some writers have even dropped the name from the list. I know 

 nothing about it, and have no faith in it ; I think Monica was a 

 small Amyntula, and should be dropped. Lyarna Tcjua is an- 

 other name that has still less claim upon the list for a place therein ; 

 Tejua was figured on the same plate with Monica ; it was shown as 

 the same style as Monica, but with one dot on each hind wing, 

 and very long and slender tails, longer and slenderer than any 

 known Lycasna carries today. I have no faith in Tejua, but I men- 

 tion the name simply to account for all known names and forms.
