Original Description of Culex magnipennis : 



Larvse of this large and interesting species were taken in a shaded pool at Sodus 

 Point, N. Y., Aug. 25, adults emerging the 29th. The female is remarkable on account 

 of her large wings with broadly rounded anal lobes. 



Description. Male. Proboscis long, curved, yellowish, specked with black, tip jet 

 black. Palpi four segmented, longer than the proboscis, not plumose; basal segment 

 globose, second sparsely, third moderately, fourth and fifth rather thickly clothed 

 with small, brown, appressed scales, a few longer, black, ventral setae on the apical 

 portion of the third and fourth segments. Antennae black, basal segment reddish, 

 subglobular; others ringed with white and bearing basal whorls of long, black hairs, 

 except the two apical ones, which are very long, slender and sparsely clothed with 

 yellowish white plumes. Eyes greenish, deeply emarginate. Occiput sparsely 

 clothed with golden yellow scales, a distinct line occurring along the posterior 

 margin of the eyes, forming a median tuft. Prothorax with distinct median and sub- 

 lateral black lines, sparsely clothed with short, golden yellow scales, slightly thicker 

 on each side of the black lines, lateral portions bearing longer, black setae. Pleura 

 sparsely clothed with short, yellowish scales. Scutellum rather prominent, irregu- 

 larly fuscous, bearing long, yellowish setae; postscutellum naked, yellowish, rounded. 

 Halteres: basal portion irregularly expanded, yellowish, transparent, apical part 

 capitate, fuscous. Abdomen brown, mottled dorsally with dark brown, nearly black 

 scales; laterally there is an indistinct row of yellowish scales; antepenultimate seg- 

 ment irregularly mottled with yellowish scales. Ventral surface suffused with 

 orange yellow scales. Coxae clothed with golden yellow scales; femora yellowish 

 beneath, dark brown above, rather thickly mottled with yellowish scales. Tibiae 

 and tarsi black, except that the former are sparsely mottled with silvery white 

 scales. Ungues of fore and mid legs unequal, one claw bidentate, the other uniden- 

 tate, posterior claws simple. Wings hyaline, sparsely clothed with brownish scales; 

 fringe slaty gray; posterior cross vein less than its own length from the mid cross 

 vein; petiole of first submarginal cell about two thirds the length of the cell, that of 

 the second about three fourths. 



A rather large mosquito measuring about 5 mm., wing spread, about 10 mm. 



Female. Antennae dark brown, sparsely ornamented with very fine, yellowish 

 white scales, and with short basal whorls of long, black hairs; basal segment sub- 

 globose with an inner patch of whitish scales. Proboscis longer than the abdomen, 

 light brown, tipped with dark brown and ornamented laterally and ventrally with 

 whitish or yellowish scales. Palpi short, brown, second joint and apex of terminal 

 segment rather thickly clothed with yellowish white scales. Eyes coarsely granu- 

 late, dark green. Occiput rather densely clothed with yellowish scales, which form 

 a line along the posterior margin of the eyes; erect black scales rather sparse. 

 Prothorax light brown, with distinct, narrow, median and submedian lines, each 

 bordered by a rather thick row of golden yellow scales; other portion of prothorax 

 rather sparsely clothed with golden yellow scales and ornamented laterally with 

 long, black setae. Pleura clothed with irregular patches of silvery white scales. 

 Scutellum slaty brown, with median and lateral patches of golden yellow spines; 

 postscutellum smooth, pinkish. Base of halteres semitransparent, pinkish, apical 

 portion capitate, dark brown. Abdomen dark brown, profusely ornamented with 

 orange and yellowish white scales in the form of broad, basal bands, the median 

 portion being narrow and composed of orange scales, while the lateral portion ex- 

 tends almost the entire length of each segment and forms a nearly complete, lateral, 

 yellowish white line; median and posterior portions of each segment dark brown 

 with a few orange and yellowish white scales, the latter nearly covering the ante- 

 penultimate segment. Abdomen clothed laterally with long, silky, white hairs;
