218 THE CANADIAN ENTOMOLOGIST. 



an extraordinary and easily recognizable colour variety of fimbriaris, 

 although at first sight it might be taken for a distinct species. From the 

 present collection it would seem to be as common as the typical reddish 

 form. Types in Mus. Brem. 



Etuoptocnemis fimbriaris would seem to be a local insect, since I have, 

 with the one exception above noted, never before met with it in^.ny collec- 

 tion submitted to me, nor have I ever collected it myself. It would seem 

 to be not only quite variable, but its scanty markings are also easily 

 removed by attrition, when it presents a vague and pale appearance, only 

 the reniform being indicated. The insect is best known by its bipectinate 

 male antenna?, its pilose thorax and weak body parts, the armature of its 

 thinly clothed legs, the well-developed fringes, silky and comparatively 

 wide wings. Superficially it rather resembles some of the red species of 

 Agrotis. It is probable that the median lines, if fully developed, would 

 be double, with pale included shade, judging from those specimens in which 

 they are marked on costa. They would then correspond with the yellow- 

 ish reniform, which appears as a broad abbreviated line or bar, edged 

 with black. But, in the specimens before me, the lines are usually 

 obliterate and, even in one fresh male, their location can be barely made 

 out, though with the help of the microscope. I trust before long some 

 locality will be found for this interesting noctuid, and its history be fully 

 made out.

Synopsis Family Japygid^;. 



The family Japygidce has representatives in almost all parts of the 

 world. Nearly a dozen species have been described, the majority of 

 which are from Europe. The species are local and rare, and not usually 

 found north or south of about 40° of latitude. Only a single genus is 

 known — Japyx. 



Japygilve. 



Antennae multiarticulate ; prothorax minute ; tarsi biunguiculate ; 

 claws equal ; abdomen with ten segments ; segments one to seven with 

 bristle-like rudimentary abdominal appendages ; caudal appendages un- 

 segmented, horny, pincer-like. 



The characters of the single genus are the same with those of the 

 family.
