ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



Location of Pupae of Megathymus cofaqui (Lep.). 



While collecting pupae and larvae of Megathymus yuccae I observed 

 in one clump of Yucca aloefolia where I was collecting, several pouch- 

 es of what I thought were Meg. yuccae but I noticed they were nearly 

 all a light colored yellow instead of black, as is common, and were lo- 

 cated on the sides and prostrate stems of the plant some were even 

 on partially rotten stalks instead of in the top of the leafy cap as is 

 usual with yuccae. My first impression was that they were the pouches 

 of new larvae and was very much surprised to find on examining them 

 that the majority contained pupae. The pupae were much smaller and 

 slightly different in appearance from yuccae. I took home a few of 

 these pupae and some of the larvae. The larvae I kept in their sec- 

 tions of the food plant with the ends put in an inch or so of water, 

 which I changed twice a week. When the pupae emerged I noticed 

 immediately that they were different from yuccae, although the latter 

 varies considerably, and after several examinations Mr. Jacob Doll 

 pronounced them to be M. cofaqui. So far I have succeeded in ob- 

 taining four males and four females and I have one or two pupae and 

 two larvae yet to hear from. The females vary quite a little but the 

 males not so much. Mr. R. E. Ludwig, of this place, has also obtained 

 one male cofaqui from a number of pupae that he supposed were 

 yuccae. He states that he did not notice any difference in the pouch 

 or position on the stem so it may be that my observations relate to 

 some purely local condition. These pupae and larvae were obtained in 

 the early part of March and I still have two that are in the larval state 

 although the others have pupated and images emerged from the pupae.

EDntomological 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 are given at 

 end of title, within brackets.

 tomology, Series A, London. For records of papers on Medical Ento- 

 mology, see Review of Applied Entomology, Series B.
