36 MAINE AGRICULTURAIv EXPERIMENT STATION. I913. 



Rhogas Canadensis Cresson. 



A specimen of this species was taken at Orono, May 15^ 

 1912, on a Norway spruce twig upon which there were many" 

 larvae of Bpinotia piceafoliana, and it may therefore possibly 

 be a parasite upon it. Mr. Cresson's description of the species- 

 reads as follows : 



"Female. Black fviscous, opaque; face, mouth, palpi and orbits, dull) 

 rufo-testaceous ; antennae fuscous ; middle lobe of mesothorax, scutel- 

 lum, most of pleura, spot on each extreme side of metathorax (some 

 times wanting), legs, except tibiae and tarsi, and the abdomen beneath,, 

 rufo-testaceous ; tibiae and tarsi, semi-circular spot at tip of first abdom- 

 inal segment, and the second and third segments except sides, luteous ; 

 apical segment pale fuscous ; wings ample, hyaline, iridescent, nervures 

 fuscous; stigma whitish varied with fuscous; metathorax and abdomen 

 finely sculptured. Length 6 mm." Cresson. Trans Amer. Ent. Soc- 

 II. 380. 1869. (Aleiodes). 



The species was originally recorded from Canada. 



This Maine specimen dififers from the above description in 

 having a dusky face, yellowish scape, and yellow basal joints 

 of the tarsi. Professor J. C. Bradley compared this specimen 

 with the type at Philadelphia verifying my determination. Lot
