REPORT OF THE STATE ENTOMOLOGIST I91O 9 



mological station, both of Paris ; the University at Zurich ; the 

 exceptionally valuable collection of forest insects in the forestry 

 school at Munich ; the natural history collections in the Sencken- 

 berg Museum at Frankfurt ; the Winnertz collections in the Uni- 

 versity of Bonn ; the Museum of Natural History, Berlin, and the 

 Museum of Natural History at Hamburg. In addition, the entomo- 

 logist spent several days with Prof. J. J. Kieffer of Bitsch, Ger- 

 many, studying his exceptionally valuable collection of Cecido- 

 myiidae, and a day with Prof. E. H. Riibsaamen at Remagen, Ger- 

 many, which was devoted largely to examining his numerous excel- 

 lent drawings and a discussion of the classification of this group. 

 A portion of a day was spent with Oberforster H. Strohmeyer of 

 Mi^inster, Germany, studying his excellent collection of Scolytidae, 

 while another day was passed with Oberforster Karl Philip at 

 Sulzberg obtaining first-hand information of forestry methods as 

 practised in Germany. 



Publications. Numerous brief, popular accounts dealing with 

 injurious insects have been prepared by the entomologist for the 

 agricultural and local press, besides a few more technical papers 

 for scientific publications. A revision of Museum Bulletin 129, as 

 noted above, was issued during the year, while the report for 1909 

 appeared July last. A tabulation of the midge galls known to occur 

 upon several plants was published in August under the title of 

 Gall Midges of Aster, Gary a, Quercus and Salix. 



Collections. A most valuable addition to the collections w^as 

 secured through the generosity of Prof. J. J. KiefTer, of Bitsch, 

 Germany, who kindly donated to the museum a number of his 

 generic types of European gall midges. These have been carefully 

 mounted and are now accessible to students in the group. A fine 

 series of Italian midge galls was secured by exchange with Dr 

 Mario Bezzi. These were carefully arranged and labeled by Miss 

 Hartman. Miss Cora H. Clarke, as in preceding years, has con- 

 tributed some valuable biological material, mostly insect galls. 



The arrangement and classification of the collection has been 

 pushed as rapidly as possible, though it should be remembered that, 

 with the limited office staff, it is practically impossible to keep the 

 collections properly classified, while the securing of extremely desir- 

 able additional material must of necessity proceed slowly. The 

 restrictions due to a small staff will become more apparent with 

 the occupancy of quarters in the new building, accompanied by the 

 obligation of maintaining a larger exhibit. The school teachers of
