pressed ; basal segment as long as the hind coxae and 

 trochanters, straight, deplanate, the spiracles subprominent; 

 postpetiole quadrate; second segment one fifth shorter than 

 first; third segment somewhat shorter than second. Segments 

 one, two and three finely aciculate-coriaceous; the following 

 segments aciculate but not coriaceous ; terebra not exserted. 



Legs not slender, somewhat stout; hind tibiae incrassate 

 towards the apex, closely setulose ; calcaria slightly curved, 

 as long as onychium, claws stout. 



Length 4 mm. 



A species with head and thorax somewhat shining and 

 abdomen dull satiny shining. Head and antennae black ; 

 clypeus testaceous, palpi piceous. Thorax immaculate black. 

 Wings hyaline, iridescent, with rosy and blue reflections ; 

 tegulae black ; radix pale ; nervures and stigma piceous. 

 Abdomen entirely black. Legs fulvous ; coxae and trochanters 

 black ; anterior femora in part, hind femora almost entirely, 

 as well as hind tarsi, nigrescent. 



Instantly known in the present genus by the sculp- 

 ture and conformation and the peculiar dullness of the 

 abdomen. Also the stout legs and especially the more 

 strongly incrassate hind tibiae are conspicuous. The present 

 species seems to be closely allied to Atractodes alutaceus THS., 

 from which the more strongly compressed abdomen and 

 the entirely black antennae will at once distinguish it.
