Imago. — Read not quite as wide as thorax ; tuft near base of each 

 antenna rather full ; palpi short, broad, densely scaly and hairy ; 

 terminal joint conical, short or very short [except in Bjcelcelce and 

 Kohcla, not projecting much beyond short hairs of middle joint] ; 

 antenna: of moderate length, with a more or less gradually-formed, 

 elongate, fusiform club, tapering to a point, more or less bent or 

 elbowed, but (except in Flesus and some intimately allied species) not 

 hooked. 



lliorax moderately stout, considerably shorter than abdomen. Forc- 

 ivings rather broad ; costa scarcely arched beyond basal curve ; hind- 

 margin entire or moderately denticulate (in Djcdaila^^ 3Iotozi, Nottoana, 

 FhyllopMla, and Flesus^ more or less excised or hollowed inferiorly 

 between second or first median nervule and snbmedian nervure) ; 

 inner margin straight ; costal nervure situated at some distance from 

 costa, except at its extremity — at or a little beyond middle — where it 

 abruptly curves upward ; discoidal cell about two-thirds length of wing ; 

 lower radial originating a little nearer to upper one than to third median 

 nervule ; first median nervule given off much nearer to base than to 

 second median nervule ; in ^ Nottoana a long costal groove or fold 

 from near base to about middle. Hind-ioings rounded, not (or very 

 slightly) produced about anal angle ; hind-margin usually slightly or 

 moderately dentate (in Dja:la:Ice decidedly so, and with a marked exca- 

 vation between second subcostal and third median nervules). Legs of 

 moderate length, rather stout, more or less hairy ; terminal spurs on 

 middle and hind tibia? long and strong, — the second pair on the latter 

 also well developed ; tarsi more or less spinulose beneath ; spur on fore- 

 tibiee rather large ; in male, fore-tibia3 sometimes {Djcclcclcc) with a long
