both Japan and Russia. IMr. Fiske is also working with an interesting 

 egg parasite of the elm leaf beetle. The Coleoptera are receiving the 

 undivided attention of Mr. Burgess. A recent communication has 

 informed the writer that 1,200 larvffi of Calosoma sycophanta have 

 been liberated. The work of Mr. Townsend with Tachina flies prom- 

 ises to give some exceedingly interesting results in the near future, 

 particularly as he is now able to recognize the various imported 

 species in any stage. These three gentlemen have an abundance of 

 assistance and we look forward to most important developments 

 within the next two or three years. 



The efficiency of tlie laboratory and the comfort of the staff con- 

 nected therewith, has been materially increased by the construction 

 of several temporary insectaries or vivaria. One, in particular, is 

 made of 2 x 4 scantling with nothing but a canvas roof and the sides 

 closely covered with fine wire mosquito netting. This gives an abun- 

 dance of room for breeding at a very slight cost. A larger building, 

 devoted mostly to the breeding of Hymenopterous parasites, has a 

 wooden roof covered with tarred paper and rough boarded sides, and, 

 while admirably adapted for its purposes, is somewhat close and un- 

 comfortable for work, being in this respect far inferior to the more 

 temporary structure described above. Entomologists would get many 

 useful hints from an inspection of this work, and we hope that in 

 the near future some of the more interesting departures will be 

 described in fuller detail. 



White-Marked Tussock Moth 



Hemerocaiitim huritstii/iiia Sin. & Abb. Thi.s well known jK'st has caused 

 extensive injuries to horsecliestnuts in i»articular. in liroolciyn. New York, 

 Albany, Troy, Utif-a, Syracuse. Rochester and Buffalo, the first and the last 

 named cities i)robai)ly sufferins; tlie jrreatest injury. This species has ex- 

 cited great interest in the fruit section of western New York by eating holes 

 in young fruit much as do green fruit worms, Xylina sp., as high as 80% 

 of the fruit being reported damaged in one instance. 



Bag Worm 

 Thyrulopteryx ephemera'formis Haw. New York City and Its vicinity rep- 

 resents about the northern extension of this species, as a rule. It was some- 

 what surprising, therefore, to receive healthy larvfe from Germantown, only 

 about forty miles south of Albany. Mr. T. F. Niles, who sent in the speci- 

 mens, states that no young trees have been set in this locality within the past 

 two years, nearer than a quarter of a mile, consequently it would seem as 

 though the species was able, under certain conditions, to maintain itself 

 considerably farther north than has heretofore been supposed possible.
