150 MAINE AGRICULTURAL EXPERIMENT STATION. 1906. 



and elm. A' Tachina parasite is active against these caterpillars 

 in Maine. 



Garden Fleas. In contrast with the past two seasons no 

 observations of the garden flea, Smynthiirus alhamaciilata, 

 Harvey, were made. During the early spring, at the time these 

 minute insects have previously been most conspicuous, contin- 

 uous rains prevented field observations on such insects as these. 

 The account of injury due to this species given in Bulletin No. 

 123 of this Station, page 220, was the occasion of several 

 requests from specialists in this group for reference to the 

 original description. Professor Harvey's description together 

 with drawings by Mr. J. H. Emerton were published in the 

 Report of this Station for 1896, pages 124-126. 



Mosquitoes. There is no adequate record of Maine mosqui- 

 toes, although in many parts of the State certain species are 

 excessively troublesome. A few collections were made this 

 season and sent to the Bureau of Entomology, Washington, 

 D. C, where several specialists are at work on this family. 

 Doctor Dyar kindly determined them as follows : 



Anopheles punctipennis Say. Orono, July 27 and October 

 I, about light in house. 



Anopheles qtiadriniacnlatus Say. Orono, September 20, in 

 house. 



Aedes fiisciis O. S. Orono, July 27. 



Acdes canadensis Theob. Trenton, August 10; Caribou, 

 August 17. 



Acdes sylvestris Theob. Trenton, August 10. 



Aides sollicitans Walk. Trenton, August 10. 



Acdes ahfitchii Felt, Htchii Felt, or siibcantans Felt. (Adults 

 alike — need larvae to separate). Orono, August 3; Trenton. 



All of the species of Acdes except fnsciis given in the fore- 

 going list were until recently commonly referred to the genus 

 Culex. 



Insects for Identification. A few, only, of the large number 

 of insects received for identification this season are recorded in 

 the following pages. 



Such common, widespread, and constantly recurring forms 

 as the cecropia moth and oyster-shell scale have been omitted. 

 Such information as the increasing parasitism of the red-humped 

 caterpillar has been summarized in a single statement elsewhere 

 in the bulletin rather than listed as 70 or 80 separate items.
