tubercle) ; the space between the basal enlargement and the recur- 

 rent shaft not exceeding the width of the latter. The shaft is 

 strongly sinuate above near the apex, the length of the sinus being 

 about equal to the width of the eye-tubercle ; the posterior end of 

 the sinuated portion is provided at the lower (posterior) outer edge 

 with a sharp tooth, beyond which the shaft is continued for a short 

 distance to terminate in a sharp point ; the tooth is situated over or 

 slightly behind the eyes when the flagellum is depressed, and is 

 never absent. The shaft is also cylindrical throughout and quite 

 smooth, except on the anterior half of the sinuated portion, which is 

 provided with an oblique and very minutely granular band, com- 

 mencing anteriorly on the upper surface and ending behind on the 

 outer side. 



Upper jaic of mandibles in $ . Terminal fang short and weak, 

 curving downwards and outwards at the apex but without sigmoid 

 flexure ; the fang flattened at the base above and slightly dilated on 

 the inner side, the dilation often minutely and angularly prominent 

 or almost toothlike anteriorly. First and second tooth large, straight, 

 followed by 2 small teeth, the anterior of which may be very minute 

 or even absent from one or both jaws, the last tooth of the single 

 series large, quadrate, emarginate at apex. Lower ja-w with 2 large 

 curved teeth and a much smaller tooth between them just in front of 

 the hind one. 



Upper jaw in ? and young with 3 large strong teeth in the single 

 series and a pair of small ones between the second and third, the 

 anterior of these small teeth very minute, although apparently never 

 absent. Lower jaw with 2 large teeth and a small one between them. 



Colour. Entirely pale yellow to reddish yellow, the skin of the 

 abdomen generally darker greyish yellow or grey (often very dark in 

 badly preserved spirit specimens). The long hairs and the bristles 

 on the legs and head-plate, and especially those on the mandibles, 

 reddish or reddish yellow ; the hairs on the abdomen yellower and 

 generally of a beautiful golden colour, sometimes with a reddish 

 tinge. Terga not differently coloured from the sides of the abdomen. 

 Malleoli pale. Head-plate irifuscated just behind the pale anterior 

 border. 



Legs and palps with a thick under-coat of very short hairs, which 

 are much more numerous than the longer ones. 



Dimensions. $ : Tibia of palp a little shorter than (18'7 : 19'1), 

 equal to, or a little longer than (17'4 : 16'9) the metatarsus + tarsus 

 and always exceeding the tibia of IV. leg (by lj 2^- mm.). $ : 

 Width of head-plate equal to or considerably less than the tibia of
