Gen. 32. CMbrOpOIltiUS, Giesbr. 1899. 



Syn: Artotrogus, Brady (part). 



Generic Characters. Body robust, with strongly chitinised integuments, 

 and with some of the epimeral lappets very prominent. Tail somewhat pro- 

 duced and having the genital segment in female less expanded than in the other 

 genera. Caudal rami lamellar, with comparatively short apical setse. Anterior 

 antennae comparatively stout and scarcely at all attenuated clistally. Posterior 

 antenna? with the terminal joint comparatively short. Siphon rather strong and 

 not much produced. Maxillse with the lobes very unequal in size and each 

 provided with 2 slender apical setse. Both pairs of maxillipeds, but especially 

 the posterior ones, very powerfully developed. Natatory legs on the whole agreeing 

 in structure with those in Bradypontius; inner ramus of 4th pair, as in that 

 genus, distinctly 3-articulate. Last pair of legs somewhat more fully developed 

 than in the other Dyspontiidce. 



Remarks. This genus, established by Giesbrecht, is allied to Brady- 

 pontius, agreeing with it in the presence of a distinctly 3-articulate inner ramus 

 on the 4th pair of legs. It differs however in some points rather conspicuously, 

 both as regards the outward appearance and some of the structural details, and 

 therefore ought evidently to be supported. We do not know at present more 

 than a single species, to be described below.

Specific Characters. Female. Anterior division of body moderately 

 expanded and somewhat depressed, with the greatest width slightly exceeding 2 /3 

 of the length. Cephalic segment large, though not occupying quite half the total 

 length, free edge evenly curved, frontal part rounded, without any dorsal crest, 

 postero-lateral corneis divided into 2 short lappets; rostral projection well defined, 

 incurved. Epimeral lappets of the 3 succeeding segments rather unequal, those 

 of antepenultimate trunk-segment much the largest, and greatly projecting to each 

 side; those of penultimate segment well developed, though smaller than the 2 

 preceding pairs. Tail attaining nearly half the length of the anterior division; 

 genital segment gradually somewhat dilated anteriorly; anal segment about the
