REPORT ON THE ENTOMOLOGICAL DEPARTMENT. 



By Dr. H. A. Hagen. 



The insect boxes of the collection have suffered somewhat from 

 the introduction of steam. Many of the oldest have warped, 

 and it may be necessary to make the bottom of the boxes of 

 two or three thin sheets, as I had done some thirty years ago. 

 These drawbacks have been counterbalanced by a more fre- 

 quent and energetic supervision. Only few pests (Anthrenus 

 varius) have been observed. 



The additions to the collection consist of a lot of mixed in- 

 sects collected by Mr. G. W. Pepper, near Taunton, Mass. ; some 

 collected by Mr. Fr. Blake of Weston, Mass., near Chicago ; 

 some very interesting biological specimens, mostly Neuroptera 

 from Florida, by Mr. H. G. Hubbard ; and other specimens from 

 Mr. G. Jack, of Montreal, Mr. T. Henshaw, of Boston, Mr. 

 Louis Cabot, of Peterborough, N. H., and Prof. W. J. Farlow. 

 Gaps in the Le Conte Collection were filled, as usual, by pres- 

 ents from Dr. G. H. Horn, of Philadelphia, Pa. A lot of Scor- 

 pions prepared for anatomical use, from Arizona, was presented 

 by the Boston Herald. Dr. F. Thomas Ohrdruf, of Gotha, 

 Saxony, presented a very valuable lot of plants injured by mite- 

 galls, containing forty types of published species ; Mr. B. P. 

 Mann, a lot of Neuroptera collected by him in Brazil ; Mr. G. 

 Barnes, a lot of American Noctuidse and other insects ; and Mr. 

 Geo. F. Atkinson, of the University of North Carolina, insects 

 destroying tobacco, cigars, and cigarettes, in all stages. 



The alcoholic collection has been carefully revised and brought 

 in order ; the determined Myriapoda, Spiders, and Scorpions have 

 been labelled and arranged, and also the types of Chilopoda ; the 

 types of the Scorpions, by Mr. E. Simon, Paris, comprising 91 

 species in 217 bottles ; the types of American Spiders, by Count 

 Keyserling, 162 species in 311 bottles ; the types of Spiders from
