discernible, followed by a heavier row of six black dots. Hind 

 wings with a continuation of the inner row of heavy black dots, 

 the last two heaviest; also the first row of spots or crescents be- 

 tween this and the margin. A large, distinct red patch in the anal 

 angle and a smaller patch of blue or purple scales. 



9 . — Similar to the male. 



Expanse 32 mm. 



Types. — One male and one female in the author's collection. 

 Eleven topotypes. One or more topotypes will be deposited in 

 the Barnes' collection. 



Habitat. — Oak Creek, Kern County, California, June 29, 1905, 

 collected by the writer. Oak Creek "flows" from the Tehachapi 

 Mountains into the Mojave desert. The type locality is in semi- 

 desert conditions, but about two miles further down are true desert 

 conditions with the characteristic tree yuccas and other desert 

 plants. 



The male specimen selected as the type was sent to Dr. Mc- 

 Dunnough, who returned it marked "A form of sylvinus close to 

 dryope Edw." There are two or three specimens in the series with 

 no fulvous on the upper sides of the wings; but the very lightly 

 marked under side and peculiar light fulvous extension on the upper 

 side mark this as a readily distinguishable desert race. 



Glaucopsyche behri australis, subsp. nov. 



This Southern Californian race of hehri (Edwards) has been 

 generally named and distributed by collectors as antiacis or poly- 

 phemiis, but as Dr. McDunnough has shown in his careful studies 

 of Boisduval's types these names cannot hold, but are applicable 

 to species or forms of the San Francisco Bay region. It is figured 

 on Plate XXIX, 367, b., c, of Wright's Butterflies of the West 

 Coast, as antiacis. Australis is very variable, much more so than 

 behri, and is evidently in a comparatively rapid process of species 

 change or formation from the probable original form of the San 

 Francisco region with large, distinct, round, black spots, known as 

 behri. The spots on the under side of the fore wing of australis 

 (type) are large but ru,n together as compared wuth behri, and with 

 white rings; while those on the hind wing are much smaller. A 

 surprisingly large number of specimens taken in the region of
