FAM. CULICID.E

to the surface. Thorax with large, long, narrow-curved scales on the mesonotum ; small fiat scales on the 

 scutellum and flat scales as the prothoracic lobes. Abdomen with flat scales arranged ventrally so as to 

 form slightly projecting tufts. Palpi very small, apparently of one segment only, scaly; antennae with 

 large globular basal joint, long hairs at the nodes, short along the internodes. Proboscis not quite as 

 long as the whole bod}'. Legs long, especially the hind pair. Apices of femora and tibiae dilated; fore 

 femora slightly swollen. Wings with normal Culicine venation, but the 3rd vein, is carried past the mar- 

 ginal cross-vein as a scaled-vein; lateral vein-scales long and nearly over-lapping those of contiguous 

 veins, their apices with marked lateral spines. Male unknown. 



This genus presents affinities to Stegomyia, but can at once be told by the marked lateral vein-scales. 

 The minute palpi however seem to place it in the Aedcomyhiae. Until the tf is found its exact position 

 cannot be defined. 



Geographical distribution of species. — One species only occurs, which is a bloodsucker 

 and very annoying.

7. SUBFAM. HEPTAPHLEBOMYINyE, THEOBALD 



This subfamily has been formed to include an aberrant species in which there is a distinct scaled 

 seventh longitudinal vein. 



Characters. — Head covered with median narrow-curved, flat lateral and upright forked scales 

 as in Culex. Thorax with narrow-curved scales and also the scutellum; metanotum nude. Abdomen 

 simple as in Culex. Palpi of 9 short, clavate, apical segment swollen. Wings with normal Cukx-scales ■ 

 fork-cells long, a distinct scaled seventh long vein present. Male unknown (1).

8. SUBFAM. CORETHRINAE, THEOBALD 



This subfamily contains two old genera Corethra and Mochlonyx to which Coquillett has recently 

 added several new ones. These insects have no true scales as in the other subfamilies and no piercing 

 mouth, but as they venation so closely agrees they have been included in the family Culicida. Undoubt- 

 edly they form a connecting link between the Culicidm and Chivonomidce. It would probably be best to 

 treat them as a distinct family : Corethrinidae. 



Characters. -- Body with hairs, not scaly. Wings with typical Culicine venation but with 

 hair-like scales not true scales, except along the wing fringe. Proboscis very short, not formed for piercing 

 Antenna^- of rj* plumose; of O pilose. Palpi about the same length in the cj and 9 ■ Scutellum simple, 

 -r trilobed. Legs long and slender, hairy, unarmed.
