necessary comparisons to determine it a new species and the de- 

 scription is withheld. It is a very beautiful species, the very heavy 

 silvery median line on head, mesonotum, and scutellum resembling 

 those of Culex serratus Theobald, while the scale positions remove it 

 from that genus. 



The genus is named for Dr. Finlay, who was probably the first to 

 suggest the connection between moscpiitoes and " yellow fever." 



CULICES. 



Culex microannulatus Theo/>. 

 Culex annulifera, sp, nov. 



9. Head covered with dark brown and light scales, two bands of white 

 flat scales on the sides, curved creamy, and dark forked scales on the occiput, a nar- 

 row white rim around the eyes, and a few brown hairs between the eyes : antenna; 

 brown, verticels and pubescence brown, but giving pale reflections, first joint testa- 

 ceous : palpi brown with small white apex : proboscis dark brown at base and ape.\, 

 with a very broad cream-colored band, equal to one half or more the length of the 

 proboscis, between : eyes brown. 



Thorax dark brown, covered with dark brown curved scales with curved white 

 and creamy scales in irregular and indefinite lines and spots : scutellum dark brown 

 with cream-colored curved scales, hairs brown : metanotum dark brown : pleurx" 

 dark, with numerous patches of white scales. 



Abdomen covered with very dark (almost black) scales and basal white bands, 

 sometimes extending as small lateral spots : ventrally largely white scaled with apical 

 white spots on many of the segments. The abdominal markings vary in defmiteness 

 in the individuals, but the dorsal basal bands and the ventrolateral apical spots seem 

 persistent, while the very small dorso-lateral spots are not. 



Legs: coxffi and trochanters all more or less white scaled : femora all dorsally 

 dark brown heavily sprinkled with white scales, white or creamy knee-spot, some- 

 times involving both sides of the joint, ventrally much lighter : tibi;\: all dark, slightly 

 sprinkled with white, and sometimes, on the fore and mid legs, a narrow white ring 

 at the apex : all the metatarsi dark with narrow basal light bands, and that on the 

 hind leg somewhat heavier and sometimes a few light scales scattered through the 

 dark ones : first and second tarsal joints on fore and mid legs have narrow light basal 

 bands third and fourth joints dark, sometimes a very small basal spot on the third : 

 all the tarsal joints on the hind legs have heavy basal white bands. Fore and mid 

 ungues equal and uniserrate, hind simple. 



Wings heavily brown-scaled ; cells small : first submarginal narrower than and 

 the same length as second posterior, the base of the latter well interior; the stems of 

 both nearly equal to the length of the cells : supernumerary cross-vein is two thirds the 

 length of the mid-vein which it meets, posterior cross-vein is as long as the mid-vein 

 and distant from it a little more than its own length. Halteres light, the knob white- 

 scaled. 



Length 6 mm., with proboscis 9 mm.
