Aedes iridipennis, new species. 



Head with pale yellow scales, some rather broad; a patch 

 of black ones on each side; bristles black. Mesonotum with 

 dense narrow curved scales, black and pale yellow intermixed, 

 the black predominating in two central bands and posterior side- 

 stripes, the yellow forming a narrow line between these, a patch 

 in front of wing-base and a border to ante-scutellar space. 

 Abdomen black, with narrow basal segmental white bands, 

 triangularly widened on the sides; venter pale, with a black 

 medio-ventral band, broken at apices of segments and some 

 black on the posterior borders of the segments laterally. Legs 

 deep blue-black, the setae pale by contrast; femora whitish 

 below towards base ; knee spots narrowly whitish. Wing-mem- 

 brane clear, strongly iridescent ; scales narrov/ly ligulate, black. 

 Claws of female toothed on front and mid legs. 



Type, female. No. 25264, U. S. Nat. Mus. ; head of Indian 

 Creek, south base of Cochise Head, Chiricahua Mountains. 

 Arizona, altitude, 6,100 feet, biting by day in a cave, August 17, 

 1917 (C, H, T, Townsend). 



A second female, Bogota, Colombia, 1918 (Fr, Apollinaire- 

 Marie), the property of the Museum of Natural History, Paris, 

 France, is very similar. The light scales of the head and meso- 

 notum are a little darker and more golden yellow, the dark areas 

 less sharply marked. The wing scales seem a little darker, and 

 tend to be denser at the bases of the fork-cells and third vein. 

 The specimen is damaged, proboscis and antennae missing, as 

 well as all legs save one fore femur and tibia and one hind 

 femur. The abdomen is well preserved. The specimen may 

 not be conspecific with the above, but seems so closs as to 

 deserve citation.
