34 LIGHTENS I A VIBTJKXI. 



much longer than the antennse ; there are several hairs 

 arising from the apex of the femur, several on the 

 lower portion of the tibia, and two very minute ones 

 on the underside of the tarsus ; digitules to claw 

 nearly as long again as the latter and very broadly 

 dilated at the apex ; those of the tarsi are slightly 

 thickened at the apex, but are not knobbed. Stigmatic 

 area (fig. 6) with three spines and a small group of 

 spinnerets. Marginal spines (fig. 6 a) shaped like a 

 mason's chisel, being gradually flattened towards the 

 extremity and suddenly truncate ; they are probably 

 hollow secreting organs, as there is a distinct trace of 

 a groove or channel on the flattened portion near the 

 apex. Mentum monomerous ; loop of rostrum shorter 

 than antennae. Inner margin of anal lobes with two 

 hairs. Anal ring with eight hairs. 



Long, 3*50-5 mm. ; wide, 2-40-3 mm. 



Ovisac of female (fig. 1) elongate-ovate, slightly 

 narrowed in front, flat convex, and composed of a 

 rather compactly- woven white cottony material, open 

 at the anterior extremity, where the body of the female 

 permanently closes it. 



Long, 4-6 mm. ; wide, 2 '25-3 mm. 



Male (fig. 7). Colour deep orange-yellow; head, 

 apodema, and all chitinised portions of thorax, as 

 well as the deepened portions of the abdomen, orange 

 brown or pale brown ; legs dusky yellow, or dull 

 orange brown ; eyes and ocelli shining black ; wings 

 beautifully iridescent under strong reflected light ; 

 costal nervure roseate. Stylus comparatively short 

 and pointed. The white caudal filaments are nearly 

 as long again as the body. Eyes (fig. 8 a), rather large, 

 placed just below the antennas ; and just within the 

 latter and towards the apex of the head is a pair of 

 larger ocelli, and above the genae a second pair of very 

 minute ones (fig. 8 /;) ; ventral ocelli (fig. 9 b) four, the 

 lower pair largest, each situate in the centre of a more 

 or less triangular plate. 



Expanse of wing, 3 mm.
