Imago. — Head not so broad as thorax, densely hairy ; ^^aZ/^i rather 

 long, with basal and middle joints densely hairy and sometimes 

 bristly, and with terminal joint of variable length, obliquely or hori- 

 zontally porrect, blunt, clothed with short appressed hairs ; antcnnce 

 short, with a stout sub-cylindrical, rather gradually-formed, slightly 

 compressed, usually straight (sometimes slightly bent) club, blunt at 

 tip ; tufts at bases of antennre long, conspicuous. 



Thorax robust, more or less hairy (especially posteriorly and be- 

 neath ^) ; pterygodes with long hair. Wings blunt, not (or very slightly) 

 prominent apically. Forc-vnngs with hind-margin usually rather convex 

 (especially in ^) ; neuration as in Cydopjides ; in $ of some species 

 (only P. Elma in South Africa), costa from near base to about middle 

 recurved so as to form a groove or deep fold. Hind-wings prominent 

 at anal angle ; hind-margin usually entire, but moderately dentate in a 

 few species (only P. Ehna in South Africa) ; neuration as in Cgclojndcs. 



Legs rather long ; fore-tibiae with well-developed acutely-pointed 

 appendage ; middle and hind tibia3 with very long and acute terminal 

 spurs, — the latter also with a second pair of spurs well developed, 

 hairy superiorly (and in $ of some species — none South-African — 

 with a conspicuous tuft of very long hair springing from its base on 



^ The (J in a considerable section of European species (of which Malro', Linn., and 

 Alveus, Hlibn., are well-known members) presents a singular pair of scabbard-shaped scaly 

 and hairy appendages, springing posteriorly from the breast at the base of the hind-legs, and 

 about one-third the length of the abdomen. They partly cover a very deep longitudinal 

 groove which occupies the basal portion of the under side of the abdomen.
