bar on the head and some mottlings on the pleura ; three more or less 

 distinct annuli on the lateral, internal and dorsal faces of the caudal 

 femora, the genicular region of similar coloration. Ventral sulcus 

 of the caudal femora blackish except for a distinct pale pregenicular 

 section; caudal tibiae glaucous blue (paler in the female than in the 

 male), blackish at the genicular extremity with a pale patellular spot 

 and a distinct pale pregenicular annulus. Eyes raw umber. Wings 

 with the disk citron yellow, apex hyaline, the longitudinal veins more 

 or less brownish, the cross veins and often some of the longitudinal 

 veins cream, transverse band well indicated but with rather indefinite 

 boundaries and very weak at the posterior anal vein, hardly following 

 the caudal margin.

The types alone have been examined. 



The special collection by the junior author was taken toward noon 

 on the shady path leading to the top of Mt. Lowe. It did not seem 

 particularly vigorous and was captured before its flight and clatter 

 could be noted. 



Anoonia integra Scudder. 



This desert-loving species was taken at three localities : Cotton- 

 wood, September 9, two males; Las Vegas, Nevada, August 10, 

 seven males, one female, one immature individual; Kelso, August 

 12, one male; Indio, July 29, seventeen males, four females. 



The series exhibits a considerable amount of individual variation 

 in size, at least in the male sex, while the color variations are exten- 

 sive as usual in the species. Specimens with green or very pale green- 

 ish in their coloration comprise half (Las Vegas) or slightly less than 

 half (Indio) of the larger lots, while the greenish individuals from both 

 of the localities are more maculate than is the case with greenish 

 individuals from Arizona. The Indio and Cottonwood individuals are 

 as a rule more uniformly maculate than the Las Vegas specimens. 

 The decussate pronotal markings are present more or less distinctly 

 in more than half the series. The Kelso individual has the entire 

 body and proximal portion of the tegmina chalky-white washed and 

 lined with pinkish-red.
