776 MOSQUITOES OF NORTH AMERICA 



The larvje live in ground pools of a temporary nature, yet such as do not 

 dry too quickly, such as woodland pools, or edges of swamps. The eggs probably 

 hibernate, and there are probably several broods during the year, eggs hatching 

 when the conditions are favorable. Professor Smith found the larvae associated 

 with Psorophora sayi and Aedes sylvestris. Concerning the habits of the adults 

 he says: 



" This is another woodland mosquito, and one which has not, up to the 

 present time, been found in towns or even on porches of buildings surrounded 

 by trees. It has never been found indoors, anywhere. The species breeds in 

 some numbers on the ridge back of South Orange, but none of the specimens 

 taken in that place were referable to this species. Outdoor captures were made 

 July 3d, at Trenton, by Mr. Grossbeck; July 4th and 5th, at Chester, by Mr. 

 Dickerson; July 13th, at Summit; July 17th and 18th, at Deckertown; July 

 31st and 33nd, at Lake Hopatcong, all by Mr. Grossbeck; August 35th, at 

 Jamesburg, by Mr. Marsh, and September 3d, in the Great Piece Meadow, by 

 Mr. Brehme. All these localities are from the more northern section of the 

 State and none are south of the red shale except the Jamesburg locality. All 

 the collectors report that this mosquito is fierce in its attack, but not one was 

 really bitten. The insects seemed to tackle low — ^that is, they rarely came above 

 the knees, Mr. Grossbeck being especially emphatic on this point. The result 

 was that these parts, being protected by the clothing, did not suflEer, while the 

 insect yet gave an exhibition of its good intentions in the matter."

We have carefully examined the types of Culex inconspicuus, which are in 

 very poor condition, and have been able to satisfy ourselves that they are this 

 species. Professor Smith kindly loaned them to us, and also the original slides 

 of the larvae. The larvae are in the third stage, not mature, and this, together 

 with some slight exaggeration of the characters which occurs in the drawing 

 (Smith, Eept. on Mosquitoes, 1905, p. 396, fig. 93), accounts for the apparent 

 specific characters shown for the larva. We therefore make the reference to 

 the synonymy positively." 



It is possible that the yellow stripes on the mesonotum may vary in width and 

 intensity of color, in which case Aedes angustivittatus may prove to be only 

 a variety of this species. The lateral white abdominal spots of Aides trir 

 vittatus are in some specimens extended dorsally to form basal segmental 

 bands.
