on the Life History of Nonagria oblonga (Grote)." [Pub- 

 lished in the present number of ENT. NEWS]. He ex- 

 hibited specimens of the insect in its various stages, as well 

 as some drawings of the same. Prof. G. N. C. Henschen gave 

 an interesting talk on "The Psychic Powers of Ants," 

 illustrating his remarks with citations from Lubbock and Forel. 

 There was a fair attendance. Chairman A. F. Satterthwait 



presided.

The Entomological Division of the Harrisburg Natural His- 

 tory Asso., met in the rooms of the Division of Zoology at the 

 Capitol, on the evening of June n, 1908, at 8 o'clock, Mr. A. 

 F. Satterthwait presiding. Mr. H. L. Viereck gave a most 

 interesting and instructive talk on the "The House fly and the 

 Possibility of its Extermination." He told of its habits, its 

 part in the spread of disease as known from experiments and 

 from its work at the Chickamauga concentration camp where 

 he became a victim of the fever. In view of the enormous 

 money losses alone from the ravages of typhoid, he thinks that 

 a crusade against the house fly would be a paying investment 

 for the Commonwealth of Pennsylvania. The proper treating 

 and enclosing of all manure accumulations in cities could easily 

 be accomplished and would go a long way toward the abate- 

 ment of the fly nuisance in town. Mr. W. R. Walton exhibit- 

 ed several specimens of the peculiar Ortalid fly Myrmecomyia 

 myrmecoides (Loew). He said that in view of the fact that 

 Aldrich gives no note of its distribution except a reference to 

 its type locality (D. C. ) and that it does not appear in Smith's 

 list of N. J. Insects it might be well to record its capture. The 

 specimens, five in all were taken in the immediate vicinity of 

 Harrisburg, three of them on blackberry blossoms, one on the 

 trunk of a locust tree and one on wild rose and all in close prox- 

 imity to locust trees. Mr. P. H. Hertzog gave an account of 

 his troubles with the wire-worms which are very troublesome 

 about Harrisburg this year.
