336 THE CANADIAN ENTOMOLOGIST 



THE OCCLRREXCE OF THE GENliS ACIIRYSO- 

 CHARELLOIDEA GIRAULT IN NORTH AMERICA. 



BY A. A. GIRAULT, GLENNDALE, MD. 



This omphalinc genus is characterized by the two grooves 

 on the scutellum and the 4-jointed clul). As regards the latter, 

 there is uncertaintN' in the following new species; for the distinct 

 terminal spine of the club, although "jointed" or constricted 

 at about its middle, is not articulated, and the club must, therefore, 

 be called 3-jointed with a terminal spine. This throws doubt on 

 the genotype as regards this character. Its description should be 

 verified. I had no opportunit\- to re-examine the type. The 

 genus structurall\- is very similar to Gyrolasella of the Elachertini, 

 but the body is metallic and the postmarginal vein is slightly 

 longer than the stigmal but not nearly half the length cf the 

 marginal. Besides, its habitus is that ni Chrysocharis; resembling 

 also Diaid.nopsis. Marginal \ein a little shorter than the sub- 

 marginal or subcqual to it. 



AchrysoGharelloidea albiscapus, new species. 



Female. — Length 0.75 mm. 



Aeneous green, the fore wings lightly dusky throughout. 

 Scape whitCj the legs golden yellow except the cox;e. Scaly- 

 reticulated, the scutellum more finely so, the postscutellum and 

 propodeum subglabrous, the latter with weakly indicated median 

 and "lateral" carinje ("lateral carinie" just laterad of the small 

 spiracle). Pedicel intermediate between the funicle joints in 

 length, 1 a little longer than wide, 2 quadrate; club somewhat 

 longer than the funicle, its joints no longer than the funicle joints. 

 Mandibles 4-dentate. Marginal cilia of fore wing somewhat 

 longer than usual (not extremely short, not a seventh of the greatest 

 wing width). Stigmal vein with a distinct neck. Parapsidal 

 furrows distinct, nearly or quite complete. Caudal wings with 

 about se\en lines of discal cilia where widest, their longest marginal 

 cilia distinctly longer than those cilia of the fore wing. Pubescence 

 very sparse. Caudal tibial spur single, small.
