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 roth to September 27th, 
was 17% 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 oth, the grubs of this species of tachina fly 
were again found in two sexta 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.

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 9th at 8 o’clock; 
a resolution was passed to the effect that, hereafter an abstract 
of the minutes be submitted to the EnromotocicaL 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
