34 STRATIOHYIDJE. 



upper facets distinctly larger than lower ones ; frons in $ 

 moderately broad; proboscis barely protruding from mouth- 

 opening; palpi small. Antennae very characteristic; in 6 first 

 two joints short, minutely bristly, 2nd rather shorter than 1st; 

 3rd with seven annulations, 1st and 2nd annulations short, bare, 

 cylindrical, about the size and length of the first two antenna! 

 joints ; 3rd annulation in the shape of a two-pronged fork with- 

 out stem ; 4th and 5th annulations similarly shaped but with 

 stems; 6th annulation elongate, much broader at tip than base; 

 7th annulation somewhat like 6th but shorter and more linear ; a 

 long terminal style of about half as long as whole antenna, com- 

 posed of very dense microscopic feather-like pubescence. In 2 , 

 two basal joints and first two annulations of 3rd joint as in <$ , 

 except that from inner or under side of tip of 2nd annulation 

 emerges a long feather-like ray, the double row of plumes 

 drooping downwards ; 3rd annulation very short, cylindrical, 

 much narrower than 2nd, bearing two similar rays ; 4th and 5th 

 annulations very elongate, narrow, cylindrical, each bearing two 

 such rays ; 6th and 7th very elongate, about as long as 4th and 

 5th, rather wider towards tips, without rays but microscopically 

 pubescent ; style as long as in tf , but apparently of a sponge-like 

 texture, generally white, w T ith microscopic pubescence. Thorax 

 elliptical, broader behind, moderately arched; scutelhun nearly as 

 long as broad, more than semicircular, with four distinct sub- 

 equal spines. Abdomen of five segments, not longer than thorax, 

 slightly broader, almost rounded, anterior corners rather angular, 

 rather thick ; c? genitalia very small, barely projecting ; those of 

 the 2 apparently telescopic, cylindrical, of two pieces and with 

 two small finger-like terminal lamellae. Legs moderately long, 

 slender, without conspicuous pubescence. Wings of normal sub- 

 family venation ; 3rd vein forked ; three discal cell veinlets 

 equidistant, including the upper branch of the 5th vein ; anal cell 

 closed at some distance from border ; wdngs folded over abdomen 

 at rest, longer than abdomen. 



Range. The Orient and South Africa. 



Only one species is definitely known as Indian, P. fastuosa, 

 Gerst., though the Indian Museum possesses two specimens in 

 bad condition from the Andaman Islands which Bigot named 

 " continua, Walk." ; but thej r cannot be this species and are pro- 

 bably P. quadridentata, I\, a species easily recognised by the large 

 golden-haired spots with angular inner corners on the anterior 

 margin of the thorax.
