the apex the flagellum terminates in a short, sharp, subulate portion, 

 at the base of which a fine, straight, pallid, bristle-like process 

 springs from the upper edge and extends backwards beyond the 

 apex. 



Upper jaw of mandibles in $ (fig. 22) much resembling that of 

 cervina, the first two teeth large, almost straight, followed by two 

 small teeth and a large one ; the terminal fang rather long and 

 slender, with strong sigmoid flexure, strongly depressed at the base, 

 curving first upwards and then at the apex strongly and suddenly 

 downwards. Lower jaw with two strong curved teeth and two or 

 three small ones between them just in front of the hind tooth ; the 

 upper surface not sulcate laterally alongside of the teeth. 



Female with 2 small teeth in the upper jaw, between the second 

 and third large tooth, and 2-3 small ones in the lower jaw between 

 the two large ones (Fig. 22) ; in one specimen there is also a 

 small tooth between the first and second large tooth in the upper 

 jaw.

 of the mandibles, the under surface of the thoracic segments and of 

 the basal joints of the legs pale yellowish ; under side of palp and of 

 the three posterior femora paler than the upper side. Ventral plates 

 of abdomen pale, with blackened lateral borders in the ? , but more 

 or less darkened in the $ . The soft skin on the sides of the abdo-
