 ? . Cephalothorax. — The two rather indistinct eyes or 

 ocular spots are removed from the front margin a distance 

 equal to their diameter. The cephalothorax, which is as 

 broad bcliind as it is long, is only one-fourth as broad an- 

 teriorly as posteriorly ; the front margin possesses a slight 

 median incision. The foremost of the two rather shallow 

 transverse grooves is straight or moderately curved back- 

 wards, while the hinder is distinctly curved forwards, and 

 so is also the hindmost margin of the second tergite, which 

 is so similar to an abdominal tergite that Lewis counted 

 it amongst them. 



The skin of the head, the first and in a less degree the 

 second thoracic tergite are everywhere beset with very 

 minute granules. The first thoracic tergite and at least 

 the hindmost part of the head bear besides a number of low, 

 round, and rather large granules and tubercles ; the tergite 

 possesses about fifty, while the head has comparatively few, 

 which decrease in number as well as in size anteriorly. The 

 cephalothorax bears some few rather slender, but blunt 

 hairs, which, at least posteriorly, are placed each on its own 

 tubercle. The granulation of the second tergite is so similar 

 to that of the abdominal tergites that I can refer to the 

 description of these. 



Abdomen (fig. 2 a). — The abdomen, which is broader in the 

 middle than it is long, is shaped similarly to that in Chiri- 

 dium ; it slopes gradually from the middle towards the sides, 

 and from the seventh tergite both forwards and backwards ; 

 the lateral outline is distinctly convex. The tergites slightly 

 increase in length from the first towards the ninth, but much 

 more in breadth towards the seventh. The second thoracic 

 as well as the first ten abdominal tergites bear a pair of 

 lateral, more or less marked projections. 



Each abdominal tergite, with the exception of the eleventh, 

 is divided into a posterior and an anterior portion by a 

 transverse raised band or line, which is more zigzag than 

 straight. These two portions are again subdivided into more 

 or less round areas by short ridges, neither so raised nor so 

 broad as the transverse band, between Avhich and the margins 

 they extend. The depressed spots thus formed bear each a 

 median knob, on which, at least sometimes, a short clavate 

 hair is articulated : in each row about twenty of these areas 

 are present ; but they are sometimes rather indistinct, 

 especially those of the anterior row, which are often covered
