Ç. Ccphalü tho rax. — Dislinct convex eyes removed I'roni the iVonl margin 

 a distance a trifle shorter than their diameter. The céphalothorax is a little longer 

 than hroad in the middle, where it is broadest ; the lateral margin is moderately 

 convex in the middle and has a short concavity or an incision opposite to the 

 posterior transverse stripe. Two prominent transverse, in the middle almost straight, 

 grooves or stripes are found, of which the anterior is very slightly curved forwards 

 in the middle, while the posterior really consists of two lateral forwards curved 

 portions, establishing a median obtuse angle, open towards the front, with each 

 other. The céphalothorax is provided all over with distinct, but rather minute, 

 conical and rounded granules as well as with distinctly clavate, fairly long hairs, 

 which are widened out towards the tip, and here as broad as long; along the front 

 margin six longer hairs are found, on the head and first thoracic tergite a good many 

 and on the second thoracic tergite 12 along and in front of the hinder margin. 



Abdomen (PI. Ill, fig. 7 a). — The abdomen is distinctly longer than broad 

 and all its tergites are longitudinally divided (the first and the last to a certain 

 degree excepted); the three first are very distinctly shorter than the following. All 

 the tergites are covered with scale-shaped granules, only wanting around fissures 

 and articulate cavities of the hairs, which consequently are placed in white spots; 

 the hairs are clavate like those of the céphalothorax, but much more elongate, 

 especially those of the last tergites (fig. 7 a). The three first tergites bear only a 

 marginal row of about 12 hairs; all the following tergites with the exception of 

 the eleventh, which has the few hairs placed without proper order, bears 6 hairs 

 in front of the marginal row; neither is the number of hairs in the latter row 

 quite constant — the fiftli having 14 and the tenth tergite only 10 f. inst. — , nor 

 their position along posterior margin, as they are sometimes placed a little in front 

 of it; the number of hairs is not always the same on each side of the longi- 

 tudinal line — the ninth tergite f. inst. bears five hairs on the right side and six 

 on the left. The eleventh tergite bears a pair of "tactile" hairs. The sternite are 

 almost smooth and bear a marginal row of about 18 almost pointed hairs and the 

 two last sternites bear in addition to these a pair of "tactile" hairs each. 



Antennae (PI. Ill, ligs 7 d-c). The flayelliun consists of four hairs, of which 

 the anterior is enlarged towards the tip with two anterior teeth (fig. 7 c). The 

 lamina interior has three dentated lobes and a short terminal spine with rather 

 long teeth; the basal of the 20 teeth of the serrula exterior is only slightly enlarged 

 dislally and the terminal not ditTerent from the preceding ones. The galea is 

 distally divided into about six teeth and is rather short, but distinctly projecting 

 beyond the terminal hair (fig. 7 c). 



Maxillae. — The maxillae are slightly granular laterally, and the interior 

 margin of the manducatory part is straight ; the lamina is rather short and broad. 



Palps (cf. PI. Ill, fig. 7 e). — The palps, which are granular all over with the 

 exception of the smooth fingers, are shorter than body; the stalks, the hand and 

 the lower surfaces are less distinctly granular than the rest. Moderately long or
