high, dry, sandy hillsides and dies down by the end of May. P. indra 

 occurs and disappears simultaneously with it. I have noticed this during 

 five seasons of collecting. During a light shower I took 2 5 on it, 

 notwithstanding large sage brush being all around to hide in. P. 

 zolicaon feeds on the same plant. The larva of zolicaon is orange and 

 black, and I have found larvae almost entirely black, which I took to be 

 P. indra. I had them pupate, but a small Ichneumon, about 2 mm. 

 long, attacked the pupae and destroyed them, along with pupae of 

 rntulus, delimits, bnicci. ciirymcdon and zolicann. all of which are 

 found there. The pupae are nearly black, while that of zolicaon is a 

 light brown. 



On July 20, 1916, I took one P. indra on Foggy Dew Creek, Okanogan 

 County, Washington, at an elevation of about 2,000 feet, also at the 

 same place a Parnassius and several Ocncis gigas. The male indra 

 seems to prefer the tops of the foothills, where it is found in company 

 with brucei and zolicaon, while what females I took were found at the 

 water edge and low canyons. It is characteristic that indra when 

 aroused always flies uphill. All my indra were taken from April 20 

 to May 25, by which time only old specimens are found. P. brucei 

 in the same place raises 2-3 broods a season, but its food plant grows 

 on irrigation ditches and is green all summer. The larva of brucei 

 will eat the wild parsley, but zolicaon and what I believe to be indra 

 will not eat the food plant of brucei, but starve instead. 



In the same region I took a hybrid of B. lorquini and B. disippus, 

 which is in the collection of the American Entomological Society.

Entomological Literature. 



COMPILED BY E. T. CRESSON, JR., AND J. A. G. REHN. 



Under the above head it is intended to note papers received at the 

 Academy of Natural Sciences, of Philadelphia, pertaining to the En- 

 tomology of the Americas (North and South), including Arachnida and 

 Myriopoda. Articles irrelevant to American entomology will not be noted; 

 but contributions to anatomy, physiology and embryology of insects, how- 

 ever, whether relating to American or exotic species, will be recorded. 



The numbers in Heavy- Faced Type refer to the journals, as numbered 

 in the following list, in which the papers are published. 



All continued papers, with few exceptions, are recorded only at their 

 first installments. 



The records of papers containing new species are all grouped at the 

 end of each Order of which they treat. Unless mentioned in the title, 

 the number of the new species occurring north of Mexico Is given at 

 end of title, within brackets.
