the pedicel and ring-joints ; the first ring-joint narrow, longer dislally, 

 about a half the length of the second which is quadrate ; joints 2, 3 and 4 

 of the funicle subequal, about a fourth shorter than joint i and each 

 slightly shorter than the one in the series of three just preceding ; funicle 

 joint 5 intermediate in length between joints 4 and 6, the latter the 

 shortest funicle joint, quadrate and about a fifth shorter than joint 5 and 

 a third shorter than joint i ; funicle joints gradually decreasing in length 

 and gradually increasing in width, the funicle cylindric-clavate, the joints 

 wider at the apex ; club short, distinctly wider than the funicle and about 

 a third its length, conic-ovate, 3 jointed, widest at the apex of the first or 

 proximal joint, which is subquadrate and equal in length to the 6th funicle 

 joint, but about a fourth or fifth wider ; the second club joint nearly twice 

 wider than long, narrowing cephalad, narrower than the proximal joint, 

 but a third shorter; the apical club joint small and conic, its longitudinal 

 axis equal to the length of the preceding joint (Fig. A) ; flagellum hispi- 

 pubescent, clavate, the hairs directed cephalad and closely applied to the 

 joints, giving the appearance of longitudinal carination to them, and ar- 

 ranged in two rows. Mandibles 4-dentate on each side and symmetrical, 

 the lateral tooth longest and most acute forcipiform, the two inner paired 

 but unequal and smallest and the mesal tooth conic ; teeth of mandibles 

 fuscous. (Fig. C).
