the eleventh slernile hears only a single pair. The slernites are not longitudinally 

 divided and bear a transverse row of 10 hairs behind the margin of the sclerites. 



(<^). Antennae (figs. 4 a-b). — The antennae are almost half as long as the 

 céphalothorax and one third as broad; they are jirovided with a good many longer 

 and shorter hairs. The immovable finger is terminated with a moderately curved 

 blunt hook; after this follow dorsally along the inner margin first three very small 

 teeth, rather apart from these a large stout tooth with several smaller ones behind, 

 which decrease backwards at least in most specimens (fig. 4 a). The movable finger 

 is more slender and moderatelj' curved without any pronounced hook; inner 

 margin with seven or eight tiny teeth (fig. 4 b). The lamina exterior is wanting; 

 the flagellum consists of four hairs of almost equal length, which bear a few 

 short teeth along the front margin (fig. 4 a, f). The serrula interior is only free in 

 its distal fifth part and consists of about 20 teeth ; the basal of these is longer 

 than the following, squarely-truncate, ones and pointed; the teeth become again 

 longer and more independent towards Hie tip; the terminal one, which is placed 

 on a level with the preceding, as well as the penultimate are always completely 

 free, pointed and serrated along hinder margin (fig. 4 a, f )■ The serrula exterior has 

 its distal third part free, is almost semilunar in shape and consists of 17 blunt or 

 fairly pointed teeth (fig. 5 a); the galea is long and moderately curved. 



La bru m (figs. 4 c-d, /, cf. p. 27). — The anterior portion is rather long and 

 broad with moderately convex sides and fairly rounded in front; il is minutely 

 reticulated above; its hindmost prolongation (p) as long as broad and fairly 

 rounded behind. 



Maxillae (figs. 4 c-f, cf. p. 27). — The maxillae have, seen from beneath, their 

 basal portion covered by the first pair of coxae; they are much broader behind 

 than in front and have the sides steep; their manducatory part is short and bears 

 three long pointed hairs. The lamina maxillaris superior is long, obtusely rounded 

 in front and projecting as far as the labrum ; the lamina inferior is very short and 

 rounded (fig. 4 d, Is-li). The median lyriform organ beneath is almost circular and 

 very prominent (fig. 4 e, f, cf. p. 28). 



Palps (fig. 4g). — The palps are almost smooth and provided with rather 

 short pointed hairs; the upper surface is in the middle anteriorly provided with 

 four tactile hairs, placed in a square {t); the immovable finger bears a very great 

 number of tactile hairs namely about 20, at least two are placed near the base of 

 the finger posteriorly; the movable finger also bears a great number viz. about 10. 

 The trochanter, which is about 15 longer than broad, has a very indistinct 

 stalk; the anterior outline is moderately convex, while the posterior has a basal 

 concavity and a distal convexity. The femur, which is about four times longer 

 than broad, has its stalk very indistinct; the anterior margin is moderately convex 

 from base to tip, while the posterior is slightly concave beyond a short basal 

 elevation; it is a Irille broader than the tibia and much longer. The tibia, which 

 is about three times longer than broad, has a distinct short stalk; anterior margin
