second segment, is prolonged into a long and thick column, which 

 consequently is placed just behind the posterior margin of the cepha- 

 lothorax ; its length is greater than that of the scutum, and equal to 

 one third of its breadth at the base, lt is almost cylindrical, mode- 

 rately thinuer towards the middle, (a feature most marked, when seen 

 troni behind) and distincly enlarged terminal ly, where it is compressed. 

 The top is provided with two spines, both situated in the longitudinal 

 section of the body; the one, the anterior, is directed forwards and 

 upwards, the other, the posterior, backwards and upwards (fig. 5). 

 Each spine as almost equal to half the length of the top of the 

 column ; the distauce between the bases of the spines equal to the 

 length of the tibial part in lateral view, distauce between tips of 

 spines equal to the length of the tarsus of the palps. The outline of 

 the body between the ocular tubercle and the column is scarcely 

 slanting, but the slope of the scutum behind the column is well marked, 

 but rather smooth. The scutum consists of seven segments, not of 

 five as generally in the Gagrellinae; the five first are marked by 

 indistinct transverse grooves ; the sixth and seventh nave no move- 

 ment of their own in this species, as their articulating membranes are 

 quite stiff and immovable. The eighth tergite is completely free. The 

 anterior portion of the scutum, as well as its descending lateral por- 

 tion, are beset with fiat granules, standing rather apart especially 

 towards the middle; the base of the column is provided with similar 

 but bigger granules, gradually merging into the rather big tubercles 

 of different size and structure, with which the median portion is armed; 

 the tubercles of the top are scarcely as big as those of the middle. 

 The tubercles of the column seem to be placed without proper order, 

 sometimes densely crowded sometimes far apart. The sixth and the 

 seventh tergites are almost smooth, the articulating membranes com- 

 pletely so. The eighth tergite is provided with bigger granules, es- 

 specially posteriorly. The sternites are provided with a single trans- 

 verse row of granules. The genital operculum, as well as the coxae, 

 bear similar but bigger granules, placed rather apart. 



Appendaeres. — The basai joint of the antennae has in the middle 

 above, where the joint is raised, a number of black granules. — The 

 palps are simple. Their femur is equal in length to the two following 

 joints, but distinctly shorter than the tarsus; the lower side is pro- 

 vided with a number of bigger and smaller teeth. The patella is en- 

 larged distally ; its inner sunface is beset with small granules, while 

 the outer and upper sides are smooth, but for a transverse row of 

 teeth along the front margin. The tibia is almost one and a hall longer 

 than the patella and about three times longer than broad. The tarsus 

 has a longitudinal row of 34 teeth with black tips, which begins near
