36 GENUS CROESUS. 



notum deep ; breast smooth, shining, -with the pubescence less dense, 

 more scattered ; cenchri pale, large ; tegulae piceous. Abdomen a little 

 shorter than the head and thorax, apex angustate, densely pilose, saw 

 projecting, sheaths hairy ; cerci short. Wings with the basal half 

 smoky, the apex hyaline, costa and stigma dark fuscous. Legs : coxse, 

 trochanters, and femora black ; knees, tibiae and tarsi white ; posterior 

 tarsi a little darker ; apex of tibiae fuscous ; posterior tarsi shorter 

 than tibiae, calcaria short. 



The <$ has the antennas short, slightly pilose. 



Length 2 lines. 



The black coxse, trochanters and femora, less pilose 

 antennge and shorter cerci and calcaria will readily 

 enable this species to be separated from padi. The 

 ? may be known from the same sex in eradiatus by 

 the wings being smoky at the base with the apical 

 half hyaline. 



Larva : head deep shining black, legs white, upper 

 half of body deep brownish, rather glistening, black, 

 lower half glistening white. The base of the second 

 and the anal segment white, the head hairy, body 

 covered with tubercles, from each of which issues a 

 long hair. 



It feeds on Rubus idceusand R.fructicosus, and in its 

 habits and mode of pupation agrees with the other 

 species. 



Bare. Clydesdale, Worcester.
