374 ('• 0. SAKS, 



having each, just above the lateral corner, outside, a somewhat oblique row 

 of densely crowded delicate bristles (see fig. 1 a). 



The urosome is of moderate size and quite smooth above, with (m\j a 

 very small spinule on either side of the dorsal face of the last segment. 



The eyes are well developed, and of an oval reniform shape, with dark 

 pigment. 



The superior antennae (fig. 3) are very short and stout, scarcely exceed- 

 ing in length ' . of the body, and about twice as long as the cephalon. They 

 are rather richly supplied with bristles, and generally have their outer part 

 extended laterally. The 1st joint of the peduncle is very large and massive, 

 considerably exceeding in length the 2 outer joints combined; the last joint is 

 extremely small, being scarcely longer than it is broad. The flagellum about 

 equals in length the last 2 peduncular joints combined, and is composed of 

 7 rather short articulations. The accessory appendage is about half as long 

 as the flagellum, and 3-articulate, the 1st articulation being about the length 

 of the other 2 combined. 



The inferior antennae (fig. 4) are perhaps a little longer than the superior, 

 and have the antepenultimate joint of the peduncle rather thick, forming 

 posteriorly an angular, densely setous projection. The last joint of the ped- 

 uncle is somewhat smaller than the penultimate, both being densely seti- 

 ferous. The flagellum is extremely small, scarcely exceeding in length the 

 last peduncular joint, and is composed of 5 articulations. 



The buccal area (see fig. 1) considerably projects below, being only partly 

 obtected at the sides by the 1st pair of coxal plates. The oral parts comi)os- 

 iug it are on the whole of normal structure resembling those in the geuus 

 Ga))iman(s. 



The anterior lip (fig. 5) exhibits the usual rounded fonn, and has the 

 terminal edge somewhat narrowed and very slightly insinuated in the middle. 



The posterior lip (fig. 7) has the inner lobes well defined, the outer ones 

 projecting outside in a conical lappet. 



The mandibles (fig. 6) are strongly built, and exhibit the usual arma- 

 ture of the masticatory part. The palp is very large, nearly twice as long 

 as the mandible, and has the middle joint the largest, being edged inside 

 with numerous long and slender bristles. The terminal joint is rather 

 narrow and somewhat compressed, with the distal part of the inner edge 

 densely setous, and having besides on the outer edge 3 fascicles of 

 bristles. 



The 1 st i)air of maxilte (fig. 8) have the basal lobe well developed and 

 of a triangular form, with about 8 ciliated setse along the inner edge. The 

 masticatory lobe and the palp are of the usual appearance.
