AN ACKNOWLEDGMENT. 



In the March number of Insect Life (p. 290), is a notice of my paper 

 in Garden and Forest, on Zeuzera jyyrina, which makes it necessary to 

 credit the observations to those who gave them to me for use. The 

 hgures used were drawn by Mr. C. P. MacChesney, of Arlington, K. J., 

 and were simply put into shape for engraving by me. Mr. Angelnian 

 found the larva, and the facts used all came to me from these gentlemen. 

 Mr. MacChesney published his own observations in Ent. Amer.^ VI, No. 

 2, and this paper must be credited as the scientific presentation of the 

 matter rather than my popular account to which accident alone gave a 

 date not intended and an apparent priority which it does not de- 

 serve. — [John B. Smith, Rutgers College. 



the genital armature in male hymenoptera. 



General Radoszkowski, at the meeting of the French Entomological 

 Society, of September 11, 1889 (see Bulletin Eutomologique, p. clxxii), 

 presented a communication on the subject of the use of the male genital 

 armature in Hymenoptera for the separation of species. Following in 

 the line of the investigations of Dufour, Sichel, Fred. Smith, and E. 

 Saunders, and adopting in the main the nomenclature of Dufour, and 

 has found that these parts are of great value in the distinction of spe- 

 cies, as they have proven to be with other orders. He has applied this 

 method of diagnosis to ujore than 40 genera and 500 species. He has 

 expressed himself as of the opinion that of all char acters known among 

 the Hymenoptera the form of the genitalia is the surest and most stable 

 for generic and specific characters as well as for varieties. The forms 

 examined seem to belong mainly to the Anthophila, MutilUdce, and Chrys- 

 ididw. 



THE man infesting EOT. 



At the 27th of March, 1889, meeting of the French Entomological 

 Society Mr. Emile Gounelle exhibited a larva taken from a man who 

 came from Brazil, and stated that similar cases were not rare, particu- 

 larly around St. Paul. Mr. Laboulbene added that he had also ob- 

 served a similar larva taken from a Brazilian woman recently arrived 

 in Paris. It was taken from a painful tumor and recognized as a species 

 of Dermatobia. It was placed in a breeding cage, but died before 

 transformation. 



THE EGGS OF ATHERIX. 



Mr. J. E. Ives, in the March number of Entomological Neivs (p. 39), 

 describes a mass of eggs taken from the under surface of a tree over- 

 hanging a small stream, which was determined by Dr. Williston as those 

 of the Leptid genus Atlierix. The same thing has recently been figured 

 and described in England, and certain egg-parasites are also figured. 

 Some thirteen years ago we collected a large number of these eggs upon
