of immovable finger loiij;, slender, and moderately curved ; 

 behind the tip, and well removed from it, is situated a strong, 

 conical, dorsal, marginal tooth, followed by about five more 

 or less distinct low and rounded teeth (fig, 2d]. 



Serrula interior (fig. 2 b) consists of eighteen teeth, of 

 ■which the proximal are more or less squarely tnmcate 

 and almost completely fused — four basal ones excepted, 

 — while the distal are much more free, pointed, and 

 minutely spined along posterior margin. No indepen- 

 dent terminal spine placed on a lower level than the teeth 

 of the serrula proper is present, as is the case in Ideobisinin 

 Balzunii and crassimanum, Bal. (comp. Hansen, 15, pi. v. 

 fig. 6b), as well as in two undescribed Indian species 

 examined by me — unless the last tooth of the serrula should 

 correspond to it. 



The galea (fig. 2 c) is slender, moderately long, curved, 

 and blunt ; a few minute teeth are noticed near the tip. 

 The terminal point of the movable finger is distinctly longer 

 and more curved than that of the other finger; above its 

 terminal hook we find a much shorter and stouter one. 

 The tip of the immovable finger is placed between these tw^o 

 when the hand is closed. Behind the described dorsal tooth 

 a long and broad marginal projection is placed, which on 

 the right antenna has the margin slightly folded (fig. 2 d), 

 and on the left (fig. 2 c) is broken up into blunt teeth. 



The serrula exterior, of which a distal third portion is 

 free, consists of about twenty teeth, which are squarely 

 truncate and touching each other in almost their whole 

 length (fig. 2 c). 



Maxilla (PI. X. fig. \a), — The labrum is well developed 

 and widened out distally. The median triangular portion of 

 the maxillae, seen from below, appears strongly raised and 

 falls steeplj laterally. In front we find, as usual, an interior 

 marginal lyriform organ, consisting of a single semicircular 

 fissure (fig. \ a, i), and more behind a median lateral 

 one, consisting of several more or less curved fissures 

 (fig. \ a, in). The terminal portion is thinly chitinized, 

 placed on a higher level than the basal region, and is 

 provided with two pointed hairs ; at its base a single very 

 long and slender one is situated. Along the terminal portion 

 a narrow lamiiia inferior (?) is placed, and in addition to 

 this a broader and longer lamina superior. 



Palps (PI. X. figs. 1 b-c). — The palps seem to be smooth, 

 with the exception of the exterior basal elevation of the 

 femur, which is granular. Longer or shorter, pointed and 

 simple hairs are abundant everywhere. The hand bears
