soil contained in a jar in the laboratory, while ten more pupated with- 

 in the body of the host, the last three segments of which were packed 

 tightly with them. Otherwise, the entire cavity of the body was empty, 

 Twenty-one (21) flies were reared from this single larva. The length 

 of the pupal instar of the fly from September loth to September 27th, 

 was iJ l / 2 days, probably lengthened somewhat by the dryness of the 

 soil in the confining jar. The variation in size of the puparia was mark- 

 ed, ranging in length from 8.10 to 4.90 mm. with all gradations. 



On October 8th and gth, the grubs of this species of tachina fly 

 were again found in two scxta caterpillars from tomato plants, and 

 twenty-four (24) puparia were afterwards obtained from the hosts, 

 averaging twelve (12) apiece. But four of these flies had emerged up 

 to November 16, 1904. The two hosts showed symptoms similar to 

 those of the first case. This parasite was kindly determined for me 

 by Mr. C. H. Tyler Townsend, Division of Insects, U. S. National 

 Musuem, as "Argyrophylax protoparcis Towns, (or a n.sp. ?)." A. A.

Doings of Societies. 



At a meeting- of the Entomological Department of the Har- 

 risburg Natural History Association held in the rooms of the 

 Division of Zoology on the evening of April gth at 8 o'clock; 

 a resolution was passed to the effect that, hereafter an abstract 

 of the minutes be submitted to the ENTOMOLOGICAL NEWS for 

 publication in its columns. In the absence of the regular chair- 

 man, Mr. P. H. Hertzog consented to preside. Mr. Henry 

 L. Viereck then spoke at some length on "The Possibilities of 

 a Universal System of Scientific Nomenclature." He first 

 gave a short review of the history of the Linnean System of 

 nomenclature and of the difficulties which had been encounter- 

 ed in recent years because of the enormous increase in the 

 number of described froms in all branches of zoology. 



It became necessary that many points be arbitrarily defined 

 in order to prevent inextricable confusion. He mentioned the 

 work of the International Zoological Congress telling what it 

 had accomplished and what it still hoped to do. 



Mr. Warren S. Fisher then presented a paper on "Insects 

 Injurious to Forest Products." Emphasizing the importance 

 of the study of forest entomology, he outlined the methods of
