metallic-green above, thickly covered with brownish hairs, and the 
ventral surface is pearl-gray. The antenne are light-brown with 
yellow-tipped knobs. The palpi and legs are brown above and light 
pearl-gray beneath. The wing expanse averages about 2% inches 
and the length of the body 5¢ of an inch. 
The caterpillars feed on hollyhock, mallow and tree mallow. 
MUELLER’S BUTTERFLY.’

This variety is so differently colored that at first glance it might 
easily be taken for an entirely different species until one becomes 
accustomed to knowing it. There is a blending of the tawny and 
black colors and a certain segregation of them so as to form no dis- 
‘tinct and sharp division lines. Usually, however, the tawny replaces 
some of the black. The large white rectangular spot on the costal 
margin is also sometimes replaced by the tawny and the eye-spots on 
the undersides of the hind wings are indicated by small indefinite 
white blotches. The color of the body, legs, antenne and palpi is 
normal of the species. The three specimens in the collection of the 
University of California average a little smaller than do those of 
the species. 
‘Dr. E. C. Van Dyke has kindly furnished the following interesting note: ‘“Varie- 
ties like muelleri Letcher, for cardui Linn. has a similar variety occasionally and speci- 
mens of atlanta Linn. and huntera Fab. have been seen which show a decided tendency 
toward the same type of markings, are in reality pathological phases which have the 
reddish markings extended or agglutinated at the expense of the other colors. They 
invariably occur during the summer or the first part of autumn and are no doubt 
sporadic seasonal phases produced as a result of certain mid-summer conditions. A 
particularly interesting thing in connection with muelleri Letcher is that a number of 
specimens occur every year, particularly in the territory back of Oakland and Berkeley, 
Cal., where the greatest numbers of the phase have been observed in the state. None of 
the specimens seen show any indication of being hybrids.”
