in front of tlic row on each side ; the eleventh tergite beai's 

 one pair of " tactile " liairs in addition to the usual, which 

 are long and placed without order. The lateral memVu'anes 

 are provided with densely placed longitudinal wrinkles or 

 ridges. The fourth to the eleventh stcrnites are scarcely 

 ditferent from the corresponding tergites. 



Antenna (fig. 1 a). — The /fa(/e(lum seems to consist of three 

 almost simple hairs. The immovable finger bears on the 

 inner dorsal margin some few minute teeth just behind the 

 tip and farther backwards three larger. The galea (fig. 1 a), 

 which is scarcely longer than the distal curved hair, has at 

 least six distal teeth. The serrula is composed of about 25 

 rather high teeth, of which the basal one has the usual wide 

 fiap. 



MaxUJce. — The maxillae, especially their distal portion, 

 which is surrounded by a broad, exteriorly dentated lamina, 

 are provided with many hairs. 



Palps (fig. 1 b) . — The palps are smooth, with the exception 

 of the exterior surface of the trochanter. The hairs are 

 rather scarce, slender, broken, and distally provided with a 

 tooth ; they appear rather long, especially on the inner side. 

 The fingers possess several tactile hairs. The trochanter, 

 which has a rather long stalk, is distinctly longer than broad ; 

 its inner outline is evenly convex, its outer more abruptly so ; 

 a slightly marked upper protuberance is present. The femur, 

 which has a short rather distinct stalk, is not so broad as the 

 trochanter ; the inner surface is in the proximal half sliglitly 

 convex and in the distal slightly concave; the outer side is 

 evenly convex. The tibia, which has a moderately short but 

 distinct stalk, is shorter than the femur and a little broader; 

 the inner surface is beyond the notch, which marks off the 

 stalk, moderately convex ; the stalk has exteriorly a basal 

 prominence, which forms part of the articulation, and a distal 

 low elevation separated from the former by a little notch ; 

 the joint proper is at first almost straight and then distinctly 

 convex. The hand, which is almost as long as but broader 

 than the tibia, is evenly convex both inwards and outwards ; 

 it is broader than high and distinctly longer than the fingers, 

 which scarcely gape when closed. 



Coxce. — The third and the second pairs of coxae are of 

 almost equal breadth and widened out distally; the fourth 

 pair, which is almost as broad basally as distally, is as broad 

 as the third is at the end ; the hinder margin is almost 

 straight and forms an obtuse rounded angle with the inner. 



Legs (figs. 1 c-f). — The scarce hairs of the legs are almost 

 all provided with one or two minute teeth distallv, and
