NEW YORK STATE MUSEUM 



work has been established and we look for a great extension of 

 interest in the local suppression of these annoying pests. 



Aquatic insects. The studies of insects inhabiting our fresh 

 waters have been continued by Dr James G. Needham. His report 

 on the work done at Old Forge was made public in the Entomolo- 

 gist's report for 1907. Dr Needham is now engaged in completing 

 his monographic account of the stone flies (Plecoptera) , a work 

 which should be ready for the printer some time during the com- 

 ing winter. Dr Betten has made good progress in his studies of 

 the caddis flies (Trichoptera), and it is expected that his work 

 upon this group will soon be completed. 



Publications. Many popular economic notices have been con- 

 tributed by the Entomologist to the agricultural and local press, and 

 a few accounts of more general interest have been widely dissemin- 

 ated through the agency of the associated press. A large number 

 of Cecidomyiidae, reared in 1907, rendered it advisable to publish 

 preliminary descriptions of these, and a reprint from the report for 

 that year, entitled New Species of Cecidomyiidae II, was issued 

 October 26, 1907. Owing to numerous delays in printing, the re- 

 port for last year did not appear during the fiscal year, as a large 

 amount of time was necessarily expended upon the more technical 

 part in carrying it through the press. 



Collections. The additions to the collections have not been as 

 numerous as in preceding years, owing to the necessity of giving 

 more attention to the arrangement and classification of material 

 on hand. A number of previously unknown Cecidomyiidae were 

 reared and several important gaps in our knowledge respecting this 

 group filled. 



Several extremely desirable accessions, aside from those men- 

 tioned above, have been made to our biological collections. One 

 of the most interesting was a complete series representing the egg, 

 larva, pupa and adult of the remarkable Taeniorhynchus 

 perturbans Walk., generously contributed by Mr J. Turner 

 Brakely of Hornerstown, N. J., the discoverer of the early stages 

 and one of the most active in working out the life history of this 

 previously very elusive species. 



Two important additions have been made to the exhibit collec- 

 tions, namely, an enlarged model of the onion fly, showing the 

 egg, maggot, puparium, adult fly and an onion infested by maggots; 

 also an enlarged model of the cigar case bearer, showing its work 

 upon apple leaves. Both of these were executed by Mrs Otto 

 Heidemann of Washington, D. C.
