BUTTERFLIES OF SAN DIEGO. 



It was my good fortune to spend two mpnths of the early part 

 of 1889 in Southern California. Arriving in San Diego on the 

 22d of January I proceeded to acquaint myself with the lepidop- 

 teraofthe vicinity. The season seemed to correspond nearly 

 with the months of April and May in the Northern States (east 

 of the Great Divide ), and though there were two or three light 

 frosts after my arrival, the spring flowers soon spangled the 

 mesas and canyons with a profusion I never saw elsewhere. For 

 a few days the majority of the butterflies I found were remnants 

 of last year's crop, worn and faded, and of species found in my 

 Dakota home. Pyrameis Cardui (known by the boys under the 

 name of Chinamen) were common on the mesas and even in the 

 streets of San Diego; Pyrgus Syrichtus was not uncommon on 

 mesas; and Danais Archippus still lingered among the Eucalyp- 

 tus trees of Maribou Park. Pyrameis Carye, then quite common, 

 was new to me. 



But the spring butterflies soon came fluttering into notice, 

 and among the first and most abundant were the Meliteas. They 

 soon crowded the mesas east of San Diego in wonderful abun- 

 dance. Though they are rare in Dakota, the speckled beauties 

 rose in great numbers before me on the uplands of San Diego. 

 There were Melitea Palla, Gabbii, Whitneyii, Quino, Anicia, 

 Editha and Chalcedona, and their numbers seemed to increase 

 until I left San Diego, on February 23d. 



The beautiful Anthocharis Reakertii was soon common in the 

 valleys and canyons east of San Diego, and my captures there 

 have proved valuable exchanges. 



Thecla Melinus, T. Augustus and T. Dumetorum (Affinis) 

 were also common. The bright green of the under side of the 

 wings of the latter species made it a conspicuous object, as it 

 flitted in the sunshine. The Theclina were distinctly home-keep- 

 ers, never going far from some bush or point which each seemed 

 to have selected as his abiding-place. 



I spent many pleasant hours (in spite of the cactus) in the 

 canyon, east and south of Old-town. It was here that I cap-
