 was beset by a half dozen Argentine ants; it is quite possible,

 course of this last fight or during previous activities. 



SIBERIAN ANOPHELES. 



. By C. S. Ludlow, 

 Army Medical Museum, Washington, D. C. 



The collections of mosquitos sent by the Surgeons of the Ameri- 

 can Expeditionary Force in Siberia, have been of much interest 

 because of the new forms they contained, and the specimens have 

 usually been in excellent condition, so that it has been compara- 

 tively easy to differentiate them. 



While there have been some smaller species as a rule the forms 

 have been large, heavily scaled, and more hirsute than the species 

 from the more southern areas. Among these new forms are two 

 Anopheles belonging to the maciiUpennis group, i. e. with spotted 

 wings, very closely allied, yet showing differences which, because 

 the Siberian forms are not well known, it seems desirable to con- 

 sider specific, and both are described below.

 dark brown, basal joint brown with a few flat brown scales, verti- 

 cels brown, scanty, and short, the pubescence is white; proboscis
