CULEX JENNINGSI 443 



were found both alone and associated with Culex stenolepis, Wyeomyia ahehela, 

 and Megarhinus superhus. 



Mexico. 



Cordoba, June 14, 1905 ; December 23, 1907 ; January 16, March 17, 1908 

 (F. Knab). 



Culex rejector was first characterized from the larva. Mr. Knab, on his 

 second visit to Cordoba, succeeded in breeding the larvge and making the adult 

 known. The adult occurs in two forms, the thorax either adorned or plain, 

 exactly as in Culex jenningsi, but we have not thought it worth while to propose 

 separate names for these forms.

Original Description of Culex jenningsi: 



$. Proboscis moderately long and slender, not swollen towards the apex, clothed 

 with black scales, not ringed; palpi short, black scaled; occiput clothed with dark 

 scales and lighter ones intermixed, margin of the eyes white scaled; mesonotum 

 clothed with dark-brown scales with bronzy luster with several faintly indicated 

 longitudinal ridges; metanotum dull brown; abdomen depressed, truncate at the tip, 

 clothed with black scales which show a bronzy luster in some lights, the second, 

 third and fourth segments have white basal bands, on the succeeding segments these 

 are represented only by triangular lateral spots, a dark-blue metallic reflection at the 

 tip of each segment, beneath the abdomen is dark scaled with distinct white basal 

 bands; legs black with bronzy luster, the knees and apices of the tibiae on the hind 

 legs silvery white, hind tarsi narrowly ringed with silvery white at the bases; pleura 

 pale greenish with two blackish longitudinal stripes; claws simple; veins of the 

 wings brown scaled, the scales long and narrow. Length, 3 mm. 



J'. Palpi long and very slender, slightly longer than the proboscis, the apices 

 blunt, black scaled without white rings; antennae densely plumose; abdomen with 

 narrow silvery-white basal bands on all the segments. Length, 3 mm. 



Four specimens, Tabernilla, Canal Zone, Panama (August Busck, collector), bred 

 from larvae in water in the leaves of Bromelias. 



Type. No. 10867, U. S. National Museum. 



Allied to Culex consolator Dyar & Knab. 



Named, at the suggestion of Mr. Busck, in honor of Mr. A. H. Jennings, Special 

 Sanitary Inspector of the Canal Zone. 



Original Description of Culex gaudeator: 



2- Proboscis moderately long and slender, enlarged at the apex; palpi short, black 

 scaled; occiput clothed with flat silver-gray scales and with numerous upright 

 forked ones, mesonotum deep-brown scaled, on the anterior half a broad marginal 

 yellowish stripe which curves inward at the middle; the posterior end of the stripe 

 may form a detached dot or the whole marking may be absent; antescutellar bare 

 space surrounded by light-colored scales, the light markings show a brassy or silvery 

 luster in changing lights; scutellum silvery scaled; pleura light brown with patches 

 of white scales; metanotum deep pitchy brown; abdomen depressed, truncate at apex, 

 clothed above with black scales, at the sides with distinct basal triangular white 

 patches, beneath black with broad white basal segmental bands; legs dark with 

 bronzy luster, the knees capped with silvery, hind tibige with a large silvery spot 

 at the apex, tarsi narrowly ringed with silvery white at the bases of the joints, the 

 last joint of the hind tarsi dark on the apical two thirds; claws simple; scales of 

 the wing-veins brown. Length, 3 mm. 



^. Palpi long and very slender, nearly as long as the proboscis, black scaled with- 

 out white rings; abdomen dark scaled with distinct bronzy luster and with narrow 

 basal segmentary white bands, which become dilated at the sides, beneath uniformly 

 silvery white, except the extreme apex. Length, 2.5 mm. 



Seven specimens, Tabernilla, Canal Zone, Panama (August Busck, collector), bred 

 from larvae in water in the leaves of Bromelias.
