Eev. T. A. Marshall's monograph of 



reasons which will be stated hereafter. The instability 

 of the colours renders the determination of the species 

 difficult, and their exhibition in a tabular form still 

 more so. 



Table of Species. 



(16) 1. Legs rufous ; ground colour of the body 



black, with or without rufous mark- 

 ings. In other words, the pale por- 

 tions of the body (if any) are rufous, 

 not testaceous. 



Podiscoidal areolet only § as long as 

 the prffidiscoidal 



Podiscoidal areolet § — 2 as long as the 

 prajdiscoidal. 



Fourth abdominal segment shining, not 

 marghied beneath at the sides. 



Antenna; GO- jointed 



Antennai with fewer than 60 joints. 



Palpi testaceous ; hind tibiae yellow 

 with black tips 



Palpi fuscous ; hind tibite rufous with 

 black tips ; (in gasterator ^ , yel- 

 lowish at the base). 



Mesopleura) with a rugose dull fovea ; 

 antenuffi J not more than dO-jointed, 

 shorter than the body 



Mesopleurffi with a punctate shining 

 fovea ; antennae J 54-jointed, as 

 long as the body 



Fourth abdominal segment (like the 3 

 preceding) dull, margined beneath at 

 the sides. 



Segment 1 distinctly longer than 2, 

 contracted at the base ; body elon- 

 gate, slender . . 



Segment 1 scarcely longer than '2, 

 hardly contracted at the base ; body 

 short, stout. 



Antenna? 48 — 52-jointed 



Antenme 37 — 40-jointed 



Legs testaceous ; ground colour of the

testaceous spot on the abdomen ; 

 belly black 

 (lit) 20. Testaceous si^ecies, with some parts
