AEDE8 SCAPULAEI8 785 



Obiginal Description op Aedes hemisueus : 



This is the species figured hy Dr. Grabham from Jamaica (Can. ent., xxxvii, 405, 

 1905) as " Culex conflrmatus Arrib." We do not believe that the insular form can 

 be conspecific with the one described from the Argentine, especially as it is very 

 different from the one identified as confirmatus from the United States. (See Aedes 

 infirmatus above.) We therefore propose a new name. 



The following is an abstract of the table : 



1. Air tube with the tuft beyond the pecten 8 



8. Pecten of the air tube with evenly spaced teeth 13 



13. Comb scales more numerous to many in a patch 21 



21. Anal segment ringed by the plate 22 



22. Air tube twice as long as wide or less, pecten of 12-14 teeth 26 



26. Scales of comb evenly splnulated without central thorn 27 



27. Body pilose 28 



28. Pecten to four-fifths of tube; tuft almost apical Uemisurus 



Obiginal Desckiption of Aedes indomiscens:

 the eyes and a median line silver scaled ; thorax bronzy brown, a broad silver patch 

 on the disk, broadest at the middle and covering the anterior two-thirds of the thorax; 

 abdomen black above, a pale bronzy longitudinal median line; beneath white, with 

 triangular black spots at the angles of the segments. Legs dark, the hind femora 

 mostly white, with a black apical ring; hind tibiae with a pale longitudinal stripe 

 on the under side, stopping short of the apex. Wing veins brown scaled. Claws of

Desceiption op Female, Male, and Larva or Aedes scapulaeis : 



Female. — Proboscis moderate, subcylindrical, uniform; labellae conically 

 tapered; vestiture black; setae curved, minute, black, those on labellae more 

 prominently outstanding. Palpi short, one-fifth as long as the proboscis; 

 vestiture black, with sparse bristly setae. Antennae filiform, the joints subequal, 

 the distal ones slightly longer, rugose, blackish, pilose; second joint swollen 

 before middle, pale basally; tori subspherical, with a cup-shaped apical exca- 

 vation, yellow, brownish-black on inner side ; hairs of whorls sparse, moderate, 

 black. Clypeus rounded in front, convex, depressed on disc, black, nude. Eyes 

 black. Occiput dark brown; vestiture of narrow, curved scales on the center 

 of vertex, broad ones on the sides, silvery-white with a yellow tint in the middle 

 and along margins of eyes, a large blackish-brown lateral spot; a group of 

 golden-yellow, upright, forked scales on the nape; setae along margins of eyes 

 black, those projecting between eyes pale. 



Prothoracic lobes elliptical, remote dorsally, dark brown, similarly colored 

 to sides of mesonotum, with minute silvery scales and dark setae. Mesonotum 

 dark brown, clothed with narrow, curved scales, a large roundedly hexagonal 

 silvery-white patch medianly on anterior two-thirds, dark brown on the sides of 

 disk and behind, yellowish-silvery around antescutellar space. Seutellum trilo- 

 bate, clothed with yellowish-silvery scales, each lobe with a group of brownish 

 bristles. Postnotum elliptical, prominent, brown, nude. Pleurae blackish, coxae 

 brown, clothed with patches of elliptical flat white scales and rows of pale setae. 



Abdomen subcylindrical, depressed, tapering posteriorly ; dorsal vestiture of 

 brownish-black scales with a slight blue reflection, with large lateral, basal, seg- 

 mental, triangular white patches, each segment with a median basal patch 

 of sordid-white scales, the patches becoming more elongate on the posterior 

 segments and forming a median stripe on the seventh one ; first segment with 

 brownish-black scales and many fine pale hairs ; venter wholly yellowish-white 

 scaled. Cerci black. 



Wings rather broad, hyaline; petiole of second marginal cell about half as 

 long as its cell, that of second posterior cell shorter than its cell ; basal cross-
