his exceptionally valuable collection of Cecidomyiidae, and with 

 Prof. E. H. Riibsaamen at Remagen, Germany, a day devoted 

 largely to examining his numerous excellent drawings and a discus- 

 sion of the classification of this group. A portion of a day was 

 spent with Oberforster H. Strohmeyer of Miinster, Germany, study- 

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

 upon several plants was published in August under the title of 

 Gall Midges of Aster, Carya, Qiiercus and Salix. 



Collections. A valuable addition to the collections was 

 secured through the generosity of Prof. J- J- Kieffer, 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 accessible to students of 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 Hart- 

 man. Miss Cora H. Clarke, as already noted, has contributed 

 some valuable biological material, mostly insect galls. 



The arrangement and classification of the collection has been 

 forwarded as rapidly as possible, though with the limited office 

 staflf it is practically impossible to keep the collections properly 

 classified, while the securing of desirable 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 Albany, Troy and presum- 

 ably other near-by localities are making extensive use of our exhibit 

 collections in connection with the regular school work. It is the 

 aim of the Department to have a representative collection of the 

 species occurring in the State, though the assembling of such means 

 the "s<^ork of years. 



The nearly completed monograph on the gall midges shows that
