HOPLOPHORA ANOMALA. 659 



Roman districts. It may be readily distinguished by the 

 large, square, chitinous projection from the progaster. 



Colour darkish yellow-brown to red-brown. 



Texture dull, coarsely pitted all over with wide but 

 shallow pits about CO to the millimetre, which often 

 cannot be seen in specimens mounted in balsam. 



Form almost elliptical, rounded jjosteriorly. 



Cephalothorax with a strong, longitudinal median 

 carina, not reaching the anterior or posterior margin ; 

 aspis divided into two portions just behind the carina, 

 the front portion is far the larger, and is pitted ; the 

 hinder part is marked with rather indistinct, sub- 

 parallel, longitudinal curved ridges. Cephalothorax 

 rather shallow in the arch ; rostral portion curved, 

 posterior portion straighter. A pair of fine curved 

 hairs just in front of the carina may be considered the 

 rostral hairs. Palpi showing plainly from the lateral 

 aspect. Maxillae and mandibles not very large for the 

 genus, the latter slightly but distinctly dentate. Pseudo- 

 stigmata rather conspicuous for the genus, not at 

 all hidden. Pseudo-stigmatic organs of moderate 

 length, setiform, somewhat recurved. Interlamellar 

 hairs long, setiform, directed forward almost hori- 

 zontally. 



Legs moderately long, the two hinder pairs are the 

 longer, abundantly provided with long setiform hairs ; 

 claws monodactyle. 



Abdomen rounded posteriorly, greatly arched ; there 

 is a large, squarish, chitinous, shelf 'like projection from 

 the progaster occupying nearly its Avhole width, and 

 overhanging the cephalothorax when the creature is 

 extended, but standing free in the air when the animal 

 is closed up. The anterior edge of this projection has 

 a notch to fit the carina of the cephalothorax. There 

 are two longitudinal rows, of about five very long seti- 

 form hairs each, on the notogaster, and two rows of 

 shorter similar hairs on each side. Genital and anal 

 plates large and about equal in size, the former almost 

 square, the latter rounded posteriorly. The dorsal
