Hudson river valley. The results of this work are given in 

 detail in the entomologist's report. A study of our mosquito 

 fauna has been undertaken and will be continued another year. 



Collections. Systematic collecting was pursued in the vicinity 

 of Albany, and considerable additions were made to the state 

 collections. Every opportunity was embraced to secure desir- 

 able specimens for exhibition purposes, and a number of addi- 

 tions have been made to the general collection exhibited in 1901 

 at the Pan-American Exposition. A small special collection, 

 illustrating the more important mosquitos and their differences, 

 has also been placed on exhibition, and arrangements have been 

 completed for supplying public schools with small collections 

 of insects at a nominal expense. The general state collection 

 has received considerable attention, and gratifying progress in 

 the systematic arrangement of the Coleoptera and Lepidoptera 

 can be reported. 



Publications. The following publications have been issued 

 during the year: Museum bulletin 46, Scale Insects of Impor- 

 tance and List of the Species in Netc York State}; Museum bul- 

 letin 47, Aquatic Insects of ihe Adirondacks; Museum bulletin 

 53, 11th Report of ihe State Entomologist ; and Museum bulle- 

 tin 57, Elm Leaf Beetle in Xew York State. The latter is an 

 extended and revised edition of Museum bulletin 20 and was 

 issued on account of the great, demand for information con- 

 cerning this serious pest of our elms. Those now in press are 

 mentioned in connection with the investigations on which they 

 are based. 



Other lines of work. The report from the corps of voluntary 

 observers and the lists of publications and of contributions, 

 contained in the entomologist's report, are records of other 

 activities of the office. 



A detailed report on the work of this division is contained in 

 Museum bulletin (34.
