Mansotiia pseudotitillans Theobald. 



Panoplites pseudotitillans Theobald, Mon. Culic, ii, 178, 1901. 

 ■• Mansonia pseudotitillans Theobald, Mon. Culic, v, 448, 1910. 



V Mansonia pseudotitillans Howard, Dyar & Knab, Monog., iii, 521, 

 P 1915. 



Evidently close to titillans if not identical. It is described as 

 slightly larger and of a yellowish brown tint. The male is not 

 known. 



Mansonia humeralis Dyar & Knab. 



Dyar & Knab, Ins. Ins. Mens., iv, 61. 1916. 



No male of this interesting species has yet come to hand, nor 

 have we noted specimens from any other than the type locality. 

 The genitalia should be of the type of titillans. 



Mansonia amazonensis Theobald. 



Panoplites amazonensis Theobald, Mon. Culic, ii, 182, 1901. 

 Mansonia amazonensis Theobald, Mon. Culic, v, 450, 1910. 



Evidently allied to humeralis, but the golden scales cover the 

 front of the mesonotum instead of being confined to the shoul- 

 ders. The male is unknown. 



Subgenus COQUILLETTIDIA Dyar 



Eggs deposited in floating boat-shaped masses! 



Mansonia perturbans Walker. 



Howard, Dyar & Knab, Monog., iii, 505, 1915. 



M. ochropiis Dyar & Knab is probably a rare aberration of 

 this species, comparable to the flaveolus form of titillans. The 

 only specimen known was taken by me near Lake Winnepe- 

 saukee. New Hampshire, in company with normal perturbans. 



Mansonia nigricans Coquillett. 



Howard, Dyar & Knab, Monog., iii, 511, 1915. 



Male genitalia. — Clasp filament simple, slender, with a long 

 terminal spine. Side piece three times as long as wide, conical, 

 excavated at base ; apex of excavation thickened, shortly pro- 

 duced and bearing a long spine, about half as long as the side 

 piece. Harpes slender, curved, with two claws at tip. Unci
