separated; frontal fovea broad, shallow, poorly defined ventrally 

 well defined dorsally and extending above the anterior ocellus; 

 immediately below the anterior ocellus is a broad, shallow, depressed 

 area; postocellar furrow present; postocellar area fully twice as 

 broad as long; head distinctly expanded behind the eyes; flagellum 

 not compressed, shorter than the thorax and distinctly thickening 

 ai)ically; basal vein and cubitus joining the subcosta at the same 

 place; third intercubitus strongly curved so the third cubital cell 

 is one-fifth shorter on the cubitus; nervulus distinctly beyond the 

 middle. Bright, metallic blue; tarsi and flagellum black; wings 

 (lark brown with a strong violaceous reflection posteriorly, becoming

ARGE PAGANIFORMIS, new species 



Closely allied to yagana (Panzer) and geei Rohwer. Can readily 

 be distinguished from both of these species by the truncate, anterior 

 margin of the clypeus. 



Femole. — ^Length, C.5 mm. Anterior margin of the clypeus trun- 

 cate, supraclypeal area strongly convex but not carinate; frontal 

 fovea broader and deeper between the bases of the antennae, very 

 slightly expanded just below the anterior ocellus; postocellar area 

 very indistinctly defined; head distinctly expanded behind the eyes; 

 flagellum cylindrical, subequal in length with the thorax; basal vein 

 joining the subc;osta slightly before the origin of the cubitus; third 

 intercubitus strongly curved; third abscissa of radius one-fifth longer 

 than the posterior margin of the third cubital ceil; nervulus received 

 at the middle of cell. Metallic blue; abdomen beyond the first seg- 

 ment f errugineous ; legs metallic except the black tibiae and tarsi; 

 wings dark brown with a slight violaceous reflection; venation, in- 

 cluding costa and stigma, black.
