SOME NEW AMERICAN MOSQUITOES 67 



ond marginal one-third of the cell ; posterior cross vein not quite its own 

 length nearer base than the anterior one ; broad ovate scales on forks of 

 second and fourth and on third veins, even the outstanding scales rather 

 broad to the sixth vein ; narrow almost ligulate scales present only (in my 

 specimen) on stems of fork veins and basal part of forks of fifth and on 

 sixth ; color of scales dark, almost blackish on the first veins, with bronzy 

 luster. Halteres light golden at base, dark at knob. 



Femora with a whitish ventral longitudinal stripe, the rest of the legs 

 clothed with brownish black, flat, nowhere raised sccJes, v^athout white 

 markings, submetallic, shining lighter bronzy beneath ; some spiny bristles 

 present, especially on the tibia and on first tarsals ; claws equal and sim- 

 ple. Length of femora 1.75, 1.65, 1.50 mm.; hind first tarsal longer 

 than tibia. 



Length: Actud, 3.8 mm.; calculated, head, 0.6 + thorax, 1.3 + 

 postnotum 0.2 + abdomen, 3 = 5 mm. 



Described from three females. Type in the collection of the Institut 

 fiir Schiffs- und Tropenkrankheiten at Hamburg; two cotypes in the 

 collection of the U. S. National Museum, Washington, D. C. 



Panama Canal Zone, caught near Corozal, MiraHores Lake, and 

 Culebra, on different days in November, 1913, by myself. 



Following the tables of Howard, Dyar and Knab (in mss.) the spe- 

 cies proves to be a Lesticocampa by the well-separated thoracic lobes, 

 the contiguous eyes, the long and slender proboscis, and the nude cly- 

 peus. In the species table it might be separated from rapax and dicel- 

 laphora by : " Scutellum entirely dark." 



The whole animal presents a monotonous brown-blackish appeeirance, 

 with lighter colors beneath ; nevertheless, in the sun, legs, abdomen, and 

 proboscis show a brilliemt bluish or greenish meteJlic luster, which is most 

 obvious on the occiput. 



Comparing our species with the tables of Theobald and Lutz we can 

 not use the male palpi. Nevertheless our species is easily excluded from 

 the genera : Rhynchomyia by the absence of the conical prominence, 

 from Hyloconops and Goeldia by the proboscis being not swollen, from 

 Trichoprosopon by the nude clypeus, from Sabethes by the absence of 

 the raised scales, from Phoniom^ia, Wyeont\)ia, and Menolepis by the 

 broad wing-scales, from Sabethoides by the position of the cross veins, 

 from Prosopolepis, Dendromyia, and Sabethinus by the slender and long 

 proboscis, furthermore from Prosopolepis by the absence of scales on
