PONTANUS, gen. nov. 



Form and shape of Derephysia, differing by the foliaceous 

 margin of the pronotum not anteriorly produced, but con- 

 vexly rounded, the anterior angles not distinguishable. 



It is necessary to denote the ])osition of the following 

 species described by AValker, but his unique type is in only 

 moderately fair condition, and hence the above brief but 

 salient generic characters must be relied upon until further 

 material is available. 



Pontanus gihhiferus. 



Mmanthia gibbifcra, Walk. Cat. Het. vi. p. 107 (1878). 



Hah. Australia. 



A species (excepting the structure of the pronotal margin, 

 as detailed above) having a general resemblance to Dere- 

 physia foliacea^ Fal 1 . 



Genus Leptostyla. 



Leptostyla cytharina. 



Monanthia ctjtharina, Butl. Proc. Zool. Soc. 1877, p. 90. 

 Hah. Galapagos Islands: James Island (C Darwin, Brit. 

 Mus.). 



Most nearly allied to L. constricta, Champ. Butler's species 

 has not been recorded by Lethierry and Severin. 



Paracopium, gen. nov. 



Allied to Copium, Thuuh., in general structure and appear- 

 ance, but having the pronotum altogether without the cellular 

 margin and the lateral margin of tlie coriura only somewhat 

 obscurely cellular on its posterior half. Antennae stout, but 

 less incrassated than in Copium, and not pilose ; second joint 

 very short and more slender than the first; third longest, 

 about twice the length of the first and second together ; fourth 

 fusiform, a little curved and reflected at base ; lateral margins 

 of the pronotum very slightly acutely prominent. 



Paracopium cingalensis. 



Dictyonota cingalensis, Walk. Cat. Het. vi. p. 178 (1873).
