A chrysalis formed at 3 P. M., August 16, 1902, excluded the 

 adult at 10 A. M., August 26, or after nine days, nineteen 

 hours. The butterflies continued to emerge until August 30, 

 in the laboratory, and on that date one was captured out-of- 

 doors. 



In 1903, in the same locality, a colony of full-grown cater- 

 pillars of this species was found on cottonwood on May 23. 

 They were taken to the laboratory and fed on willow. 



June 6, 1903 — Pupation commenced. 



June 9 — Chrysalids. 



June 19-21 — Butterflies. 



This would indicate at least two broods; there is time for 

 three. 



On the Genus Anaxipha (Orthoptera ; Gryllidae). 

 By James A. G. Rehn and Morgan Hebard, Philadelphia, Pa. 



An examination of material of the genus Anaxipha from 

 the United States shows that two species occur in North Ameri- 

 ca, north of the Rio Grande. It is also true that Scudder's 

 Cyrtoxipha delicatiila is a synonym of the less well known of 

 the two, Anaxipha pidicaria (Burmeister), being based on the 

 long-winged form of this species. We have before us Scud- 

 der's type of delicatiila and other long-winged individuals re- 

 ferable to both species of the genus. The perforation of both 

 faces of the cephalic tibise has been considered of great impor- 

 tance in the separation of Anaxipha and Cyrtoxipha, while the 

 macropterous condition found in forms of Cyrtoxipha had not 

 been reported in the other genus. The type of delicatiila has 

 the tibiae doubly perforate and the wings are decidedly caudate, 

 but a peculiar facies to the head and pronotum seen in forms 

 of the genus Cyrtoxipha is not apparent in the specimen. 



We have been able to bring together for examination a con- 

 siderable number of specimens of both forms of the genus, in- 

 cluding a number of long-winged individuals, and we find that 

 while the majority of the brachypterous individuals have the 

 cephalic tibiae uniperforate, two short-winged specimens of 

 exigua have the same portion strongly perforate on both faces,
