intersected with black ; below dark, ashy ; forewings with 

 black ocellated spots ; secondaries with a broad, transverse, 

 toothed, white band and with black, ocellated spots in the 

 basal area? (basilaribtis.)

This beautiful species does not resemble any of our European 

 species. It is a little larger than our battus. Above the wings 

 are violet-blue with a rather wide dusky border and white 

 fringe broken with black. Below it is dark cinder-colored ; 

 the forewings are marked with one basal spot, with a central 

 lunule and with a sinuous line of well ocellated black spots; 

 outside of the sinuous line one can see a sort of whitened 

 band followed by little black crescents. On the secondaries 

 the base is even more obscure and offers towards the base 

 some black, ocellated spots, upon the cellule a whitened blot, 

 next in order a row of black spots followed by a very clear 

 white transverse band, toothed like a saw. 



The female differs from the male in that one can perceive on 

 the upper side of the secondaries the trace of two or three 

 obsolete tawny lunules. 



This charming Lycaena was taken by M. Lorquin in the far 

 South in the vicinity of Los Angeles. 



From the above descriptions I draw the following conclu- 

 sions : 



The under side of L. rhaea (or more properly speaking L. 

 sagittigera, Felder, syn. L. rhaea, Boisd., since Felder de- 

 scribed it before Boisduval's second paper was published) is 

 strikingly different from any other species. Boisduval no- 

 tices this at once in his description. If Lorquin had sent him 

 any of these specimens prior to 1852 he would have describ- 

 ed them fully in his first paper just as he did in his second 

 paper. Sagittigera reaches its perfection in Southern Califor- 

 nia where Lorquin collected it subsequent to 1852. 



Concerning L. piasus this is not strikingly different from 

 certain other species and Boisduval did not exert himself to 

 give a careful detailed description. We note its juxtaposi- 

 tion to L. pseudargiolus in the list of descriptions, and we 

 know that it is somewhat different. It is one of our com- 

 monest spring butterflies and Lorquin could not have failed 

 to send a large series of them prior to 1852. If Boisduval 

 intended his description of piasus to cover sagittigera, where
