short, transverse; the last pointed. 



The lahivm consists firstly, of a triangular or heart-shaped nientum, en- 

 closed between, and connate with the cardinal pieces of the maxilla?; a fine 

 impressed line indicates their suture ; secondly, of a short, transverse, palpi - 

 gerous piece, bearing on each side a short. 2-jointed palpus, with a stout 

 basal and small narrow terminal joint; thirdly, of a large horny piece, situ- 

 ated behind the latter one, and occupying the whole width between the 

 lobes of the maxillae. It is bisinuated anteriorly and as it projects above the 

 palpi, the latter are very indistinct, and appear concealed in an excavation. 



First thoracic segment but little longer than broad, deeply punctate, 

 like the head; a transverse furrow, running near by, but somewhat obli- 

 quely to, the anterior border, separates anteriorly a narrow, densely striate 

 band, which is broader on both sides than in the middle; a second trans- 

 verse, but less definite furrow runs from the middle of the back, where it 

 is almost obsolete, down both sides, reaching the first furrow on the under- 

 side of the body. 



Second and third thoracic segments transverse, almost three times broad- 

 er than long, deeply punctate, like the first. The stigma is placed on each 

 side near the anterior margin of the mesothorax. 



Feet inserted in a depression on the underside of the thorax; they are 

 very short, approximated at their bases and consist, besides the coxa, of 

 three short, stout joints, the last of which ends in a strong unguis. 



Abdominal segments, eight in number, cylindrical, broader than long, 

 perfectly annular, as there is no visible suture on the sides or below, sep- 

 arating the ventral from the dorsal segments. The dorsum is punctate, 

 but more sparsely than the thorax; the venter is smooth, except at the 

 posterior margins of the segments, which are finely striate. The eighth 

 segment is punctate all round, and more densely than the others. The 

 posterior part of this segment is obliquely truncate and is closed posterior- 

 ly by a round, flat, horny piece, punctate on the outside and which can, 

 to a certain extent, be opened and closed like a lid, being connected by a 

 hinge superiorly and an expanding membrane inferiorly. This lid is to 

 be considered as the ninth segment of the abdomen. 



The segments 2 — 7 of the abdomen, have each, on the dorsal side, near 

 the anterior margin, a pair of deep pits, somewhat angular anteriorly. 



The eighth segment has, on the same place as the pits of the previous 

 segments, a pair of short, oblique grooves, running towards the anterior 

 incisure and finely striated at the bottom. The presence of eight pairs of 

 abdominal stigmata is indicated by small, round, smooth discs or depres- 

 sions, with eleA^ated margin, situated on both sides of the body, on the
