some badly worn, near Goldroad and Little IMeadows. Sev- 

 eral more were taken at the same places in 191 1 and 1912. 



Further east in Arizona at Ash Fork, Jerome, in the 

 Verde River valley below Jerome, and further south at Phoe- 

 nix, I have not seen californica but have taken S. crocale in 

 the Verde Valley and at Phoenix. Mr. Wright told me that 

 he took all of his specimens in a canyon in Riverside County, 

 California, on the east slope of the San Jacinto range, about 

 opposite Palm Springs on the Southern Pacific Railroad. In 

 May, 1913, I saw several just a little north of this on a moun- 

 tain road west of Banning, which I am quite certain were S. 

 californica, but could not obtain them as I had no net with 

 me. I rather believe they are to be foimd in the foothills all 

 along the Colorado River valley, and the valley running up 

 through Imperial and Riverside Counties, which opens into 

 the Colorado valley, 



L. bachmanni. 



This species is fairly common in the fall season about Gold- 

 road, Arizona. In October, 1910, they were very numerous, 

 especially in the stretch of valley below Goldroad, where 

 Bigelovia graveolcns was in full bloom. Riding horseback on 

 a windy morning through this brush, I could see twenty or 

 thirty at a time tailing out to leeward from every clump of 

 graveolcns. Catching them was not an easy matter. T would 

 look forward to netting at least half a dozen specimens from 

 one of these groups, but after one or two ineffectual passes 

 with the net they would all disappear. Observing them care- 

 fully, I noticed that instead of flying away they would dart 

 into the thicket and alight on the dead twigs with their wings 

 folded and their antennae pointed forward in line with the 

 perch on which they sat. Here they would remain motionless 

 until my hand or the net approached within a few inches of 

 them, when they would dart away and settle on another perch. 

 The under side of the wings, when folded, has a perfect pro- 

 tective gray coloring which matches the gray of the twigs, 

 and it was interesting to note the evident use these insects 

 made of it.
