Original Desceiption of H^magogus splendens. 



$. In ground-colour deep black, the base of the femora, and the coxge in part, 

 somewhat yellowish. Occiput, mesonotum and scutellum wholly covered with 

 brilliant green and coppery squamulae; pleurae densely snow-white squamulate. 

 Abdomen brilliant steel-blue, in some reflections black; a spot on the sides of each 

 segment snow-white. Legs blue, like the abdomen, shining black in some reflections; 

 the undersides of the femora, towards the base, with white squamulae. Wings 

 hyaline, somewhat brownish in front, squamulae black, evenly distributed. Length 

 5 mm. 



Eight specimens. 1000 feet. The single male specimen was injured after the 

 drawings were made. It does not appear to differ, however, from the female. The 

 colouring must be much like that of Culex cyaneus, save the head and thorax. 



Description of Female, Male, and Labva of H.,emagogus splendens: 



Female. Proboscis long, slender, subcylindrical, uniform, labellae conically 

 tapered ; vestiture deep blue-black ; setae minute, curved, black, those on labellae 

 more prominently outstanding. Palpi small, less than one-sixth as long as the 

 proboscis; vestiture black, with a few moderate setae. Antennae filiform, the 

 joints subequal, rugose, coarsely pilose, black; second joint slightly swollen 

 beyond middle; tori rather small, subspherical, with a cup-shaped apical ex- 

 cavation, black, with a few minute hairs on inner side. Clypeus rounded tri- 

 angular, convex, prominent, black, nude. Eyes black. Occiput clothed entirely 

 with broad, flat, dark metallic blue scales with an iridescent reflection; pos- 

 terior part of cheeks and under surface silver scaled ; bristles along margins of 

 eyes coarse, black, a pair of longer black ones projecting between the eyes.
