the back, one on each side, and two near each of the late- 

 ral margins ; the sixth segment is quadrate ; the seventh, 

 eighth and ninth gradually narrowed to the tip, which is 

 entire, with the two very minute caudal styles scarcely 

 visible at the sides ; the operculum is swollen in the middle, 

 and extends beyond the extremity of the last dorsal seg- 

 ment. The legs are short ; the anterior femora curved at 

 the base ; the tibiae simple ; the four posterior femora 

 thickened, and serrated beneath ; the tibiae short, simple, 

 but slightly dilated within near the base, and the middle 

 pair have a slight dilatation on the outside towards the 

 base.

The whole insect is of a pale brown colour, with the legs 

 paler luteous brown, and the extremity of the abdomen 

 paler ; it is covered with minute pale glossy granules, and 

 has a very fine polished line running along the middle of 

 the thorax and abdomen on the under side ; these granules 

 are fewer on the abdomen. The head is furnished with 

 two small raised spaces between the eyes. The mesothorax 

 is considerably elongated, as is also the metathorax, which 

 is strongly divided near its extremity into two parts by a 

 transverse line. The abdomen is entire, gradually widened 

 to the fourth segment, behind which it is gradually nar- 

 rowed, the three terminal segments being narrower than 

 the head ; the last (ninth) dorsal segment is subemarginate 

 behind, exposing a small rudimental joint, and with two 

 small styles at its outer angles. The operculum extends 

 nearly to the extremity of the ninth dorsal segment, be-- 

 tween which and it are to be seen three pairs of dilated ap- 

 pendages, forming the internal organs of generation. The 

 fore legs (as well as the antenna;) are broken off in the 

 unique specimen in the National Collection. The four 

 hind femora are slightly thickened at the tip, with two or 



three minute spines, and the tibiae and tarsi are simple. 

 The presternum and mesosternum are divided into two 

 parts by a transverse line across the centre of each.

Head unarmed, convex, black above, variegated with 

 pale luteous brown or buff marks, two more conspicuous 

 spots between the eyes, and two broader stripes extending 

 from the eyes to the back margin of the head ; upper lip 

 luteous ; palpi pale brown. Antenna? black (more than 

 \\ inch long), irregularly ringed with luteous ; basal joints 

 moderate-sized. Prothorax longer than usual, dirty luteous, 

 with a large elongate-triangular black patch extending down 

 the middle from the anterior margin ; lateral margins with 

 a dark stripe and an oblong dark patch near each posterior 

 angle ; anterior angles obliquely truncate for the insertion 

 of the spiracles ; lateral margins also deeply emarginate 

 above the insertion of the fore legs. Mesothorax but little 

 longer than the prothorax, black above, slightly varied with 

 luteous, armed in the middle towards its hinder margin 

 with a strong erect spine, which is swollen behind. Meta- 

 thorax of the same length as the mesothorax, its anterior 

 portion only one-third of its whole length, dirty luteous 

 with black dots ; each division armed behind with a coni- 

 cal tubercle, the hinder one being the largest. The ab- 

 domen is dirty luteous, with small black dots arranged 

 symmetrically ; the first and second segments with a small, 

 the third with a conical raised tubercle, and the fourth with 

 a large raised semicircular crest ; the two anal styles short, 

 slender, and obtuse ; the operculum extending beyond the 

 extremity of the abdomen, slender. The legs are rather 

 short, the hind ones scarcely extending beyond the extre- 

 mity of the abdomen ; the fore femora rather thicker than 

 the others, dirty luteous, with a dark patch near the end ; 

 middle and hind femora varied with small black spots ; 

 tibiae and tarsi ^aried with black and luteous. Body
