thorax covered with a dense short ochraceous pubescence ; the disk 

 of the thorax thinly sprinkled with short black hairs ; the posterior 

 tibiae obscurely ferruginous; the tarsi ferruginous; thelegs coveredwith 

 bright golden-yellow pubescence ; wings subhyaline, the nervures fer- 

 ruginous ; the tegulae yellow with a fuscous stain in the middle. Ab- 

 domen obscurely chalybeous, closely punctured, the two basal segments 

 strongly so ; the apical margins of the segments with smooth shining 

 narrow blue fasciae. 



Male. Closely resembling the female, but with the legs black; the 

 posterior femora incrassate, the tibiae narrow at their base and broadly 

 dilated at their apex, which, as well as the calcaria, are pale testaceous. 



This species closely resembles a species from North China, N. chaly- 



beata, Westw. MS., from which it is readily distinguished by the form 



of the fourth ventral segment, which is notched in the middle, 



rounded, and then emarginate with the lateral angles rounded; in the 



species from China the margin is arched, and fringed with fulvous 



pubescence.
