Obs. D. mgrimaculatus, Mq. (Ct. Guide, 1258. 2), is doubt- 

 less a misprint for D. nigrilamellatus, Mq. (Brassy- green, an- 

 tennae black, arista naked, legs black or piceous, wings smoky- 

 hyaline ; male with black lamella. Length 2| lines.) 



Obs. D. chalybews, Wd. (Blackish-green, front and thorax

 very pubescent, legs yellow, tip of hind femora, hind tibise ex- 

 cept the base, and tarsi black, anterior metatarsi yellow, wings 

 blackish, the cubital and subapical veins nearly parallel ; male 

 with yellowish lamellae edged with black. Length 2 lines), has 

 been admitted into the British lists, perhaps by mistake for D. 

 chalybeus, Mg., which is treated as a variety of species 9, in the 

 first section.
