158 INSECUTOR INSCITI^ MENSTRUUS 



parallel to the side piece and similarly haired ; basal lobe 

 quadrately expanded, densely tubercular, with moderate setae; 

 a stout spine with hooked tip on the lower margin and a 

 shorter straight one above the middle of the side margin. 

 Harpago with short stout hirsute stem, a seta at base and 

 two before apex ; filament thickly fusiform, short, pigmented. 

 Harpes normal ; unci membranous. Basal appendages short 

 with four or five terminal spines. 



"As compared with dorsalis Meigen of western Europe, to 

 which this species is allied, the two spines on the basal lobe of 

 the side piece are much more remote. They are also more 

 remote and differently placed from the corresponding spines 

 in curriei Coq., the North American representative. I con- 

 sider the species distinct on genitalic characters." 



Taken, the male at Mostovoi, July ; the female at Vladi-

 American Expeditionary Force, Siberia. The male was taken 

 at Mostovoi early in July by Major R. E. Graham, M. C, 

 U. S. Army, the female was taken at the Emergency Hospital, 

 Vladivostok, August 5. Although the collections from Siberia 

 have been received in excellent condition, and contained many 

 specimens, these are the only two of this species, none of those 

 belonging to the more or less closely allied forms showing the 

 brilliant thoracic markings. 



Aedes cyprius, new species. 



Female : Head brown, covered with yellowish white broad 

 curved scales over the vertex and occiput, and extending well

 deep yellow and brown with white flat fragile looking scales,
