Obiginai. Desceiption op hwmagogus splendens. 



5. In ground-colour deep black, the base of the femora, and the coxae 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 Gulex cyaneus, save the head and thorax.
