Hab. : Reno, Nevada. Two 2 specimens ex pupae. One 

 in my own and one in Mr. Fred Burns' -Coll. 



A number of specimens of H. burnsi have hatched out 

 asymmetrically; in fact I know no insect which has thrown so 

 many erratic specimens in which the wings of one side are 

 oddly marked. One curious female specimen has the right 

 half as in the female of ab. conjuncta and the left one as in 

 the normal female with the addition of a patch of black scales 

 between the discal spot and the submarginal band. More heav- 

 ily marked on the nervures. 



The hybernated pupae from last season commenced to hatch 

 with two days of this year's brood, though here in the north 

 of England, they must have been subjected to very diverse 

 temperatures from those in Nevada.

By E. B. Williamson, Bluffton, Indiana. 



A specimen from the Wabash River near Bluffton, Indiana, 

 compared with a specimen from Wister, Oklahoma, has col- 

 ored areas of wings more extensive; there is more brown in 

 the membrane of the fore wing in the colored area (in both 

 cases brown is anterior to A for the full length of the colored 

 area and, distal to the quadrangle, extends across the full width 

 of the colored area but it is evident only on close examination, 

 because it does not extend beyond the area of pink veins) ; in 

 the hind wings the colored area is about the same in extent 

 and shape in the two specimens, excepting that in the Indiana 

 specimen the distal prolongation of the brown area toward 

 the nodus is carried farther (3.5 mm. distant in Wister speci- 

 men, 3 mm. in Indiana specimen). 



In the case of the Wister specimen, however, the body colors 

 are distinctly and conspicuously darker, having metallic re- 

 flections, compared with the dull black of the Indiana speci- 

 men. The humeral stripes, strongly evident in the latter, are 

 not represented at all in the Wister specimen ; and the exten-
