CULEX REJECTOR Dyar & Knab. 

 Culex rejector Dyar & Knab, Journ. N. T. Ent. Soc, xiv, 207, 221, 1906. 

 Oeioinai. Description of Cxjlex eejectok: 



Antennas with the tuft near the outer third, pale; head hairs, the upper tuft 

 multiple, the lower single; body glabrous; lateral hairs in twos on segments 2 to 5, 

 single on the sixth; tracheal tubes narrow, angled. Air tube very long, 10 X 1, 

 nearly straight, with four small tufts on posterior margin; pecten of very long 

 spines to one-fifth. Lateral comb of the eighth segment of long spine-like scales. 

 Lateral tuft of the anal segment very large; gills long and pointed. 



Collected by the junior author in a large Bromeliaceous plant at Cordoba, Mexico, 

 with C. gravitator. All these larvae died, presumably from lack of their natural food. 



The following is an abstract of the table : 



1. Antennas with the tuft outwardly placed, the part beyond slender. . 5 

 5. Air tube four times as long as wide or over 7 



7. Anal appendages four, normal 8 



8. Air tube with four to ten paired tufts along the posterior line in a 



straight row, none displaced, or the hairs obsolete or absent. 18 



18. Air tube without a crown of spikes, smooth throughout 19 



19. Air tube with small double or single hairs or bare 31 



31. Air tube uniform, without any swelling 32 



32. Air tube with slight tufts 33 



33. Pecten of the air tube reaching one-fourth or less 35 



35. Pecten sparse and long 36 



36. Lateral hairs in twos after the second segment; comb of the eighth 



segment of very long spines rejector 



Desceiption of Female, Maim, and Labva of Cuibx eejectok: 



Female. — Proboscis slender, Tiniform, labellae conieally tapered; vestiture 

 bronzy black; setse minute, curved, black, those on labellae more prominently 

 outstanding. Palpi short, less than one-fourth as long as proboscis, slender, 

 bronzy black. Antennae moderate ; joints subequal, rugose, pilose, black ; hairs 

 of whorls sparse, moderate, black; tori subspherical, with a cup-shaped apical 

 excavation, luteous, darker within. Clypeus rounded triangular, blackish 

 brown, nude, small. Eyes black. Occiput blackish, clothed broadly with 

 narrow, curved, pale ochraceous scales; ocular margins white scaled; cheeks 

 clothed with broad, flat gray scales; many slender, erect, forked, brown and 

 ochraceous scales dorsally. 



Prothoracic lobes elliptical, remote dorsally, brown, clothed with narrow 

 whitish scales and black bristles. Mesonotum dark brown, an impressed median 

 line, on either side of it a bare stripe ; vestiture of small narrow, curved, bronzy 

 brown scales, uniform, or the scales on anterior angles and anterior half of 

 lateral margin broadly shining yellowish, forming a lunate patch on each side, 

 those surrounding ante-scutellar space grayish white. Scutellum trilobate, 

 clothed with narrow, curved whitish scales, each lobe with a tuft of black 

 bristles. Postnotum elliptical, prominent, dark brown, nude. Pleurae greenish, 

 with a transverse dark band under the wing and another across the middle; 

 some patches of small elliptical white scales ; coxae pale yellow. 



Abdomen subcylindrical, depressed, truncate at tip; dorsal vestiture black 

 with a strong bronzy reflection, a row of narrow basal segmental white bands or 

 median dorsal white patches, or without any dorsal markings ; a row of lateral, 

 basal, segmentary, triangular white patches, joining bands when present; venter 

 whitish scaled. 



Wings moderate, hyaline; petiole of second marginal cell about half as long 

 as its cell, that of second posterior cell as long as its cell ; basal cross- vein dis- 

 tant more than its own length from anterior cross- vein; scales of veins rather 

 long, linear, brown, those on costa blackish with a bronzy and blue luster, scales 

 on fork of second vein denser, narrowly ovate. Halteres whitish, with black
