ANTHOPHILA. 



Stelis JAPONICA, Sp. nov. 



Niger, abdoinine rufo, basi niger ; alls violaceis, basi fere 

 hyalinis ; apice scutelli excisa. Long, fere 12 mm. 



Hab. Japan. {^George Lezvis). 



Scape sparsely covered with pale hair, the flagellum 

 microscopically pilose ; the tip obscure rufous. Head 

 rugosely punctured ; the sides of the face thickly covered 

 with long white hair ; the vertex and mandibles more 

 sparsely haired ; mandibles rugosely punctured, but not so 

 coarsely as the head, the apex shining, impunctate. Thorax 

 rugosely punctured ; the scutellum with larger punctures 

 than the mesonotum ; shortly pilose ; the metanotum 

 covered with long white hair. Mesonotum with a distinct 

 furrow down the centre. Scutellum with the apex pro- 

 jecting over the metathorax, margined, with a slight but 

 distinct waved incision ; at the base there is a deep curved 

 furrow in the middle. Abdomen shining ; punctured, 

 rugosely punctured towards the apex ; the segments im- 

 punctate at their junction, and depressed at base and apex ; 

 the apial dorsal segment with a distinct raised margin and 

 slightly incised in the middle. The femora coarsely 

 punctured, closely covered with pale to blackish hair ; the 

 tarsi thickly covered with fulvous hair on the lower side ; 

 and sparsely with pale hair above ; calcaria brownish. 



The late Mr. F. Smith records {Trans. Ent. Sac, 1873? 

 p. 204) Stelis abdominalis, a species described by himself 

 from Celebes {Proc. Liin. Soc, 1858, p. 7), from Japan. It 

 is of course possible that he may have had the true Stelis 

 abdominalis from Japan, but it appears to me that the 

 species I have just described cannot be abdominalis, in as 

 much as the latter differs from it in several respects ; 

 namely, in being nearly two lines smaller ; in the abdomen 

 being entirely ferrugineous, in the " posterior margin of the 

 scutellum being rounded," and the wings are uniformly 

 coloured.
