both pro thorax and elytra is perfectly even {e.g.^ does not alter 

 its character at all to^vards the margins), except that on the 

 elytra there is a scarcely traceable indication of some longitudinal 

 Isevigate lines (they are so faint and irregular on the example 

 before me as to be perhaps only accidental). Looked at obliquely 

 from the side,. the humeral angles of the elytra appear very well 

 defined and the external outline of the elytra is quite strongly 

 concave from the humeral angles nearly to the middle of the 

 margin. The under surface is nitid and without distinct sculp- 

 ture. The presternum is widely and strongly compressed along- 

 its whole leng-th, the surface of the broad elevation thus formed 

 being flattened and protruding well behind the anterior coxse, it& 

 hinder extremity being strongly and triangularly emarginate ; its 

 width between the anterior cox^e is about equal to the width of 

 the anterior tibiae at their apex. This species belongs to Dr.. 

 Chapuis' Second Group of Pavopsis.

P. hemisjylim'ica, Chap., var. ? Meyricki. Hemisphjerica ; valde 

 convexa ; nitida ; supra rufo-testacea, capite paullo obscuriori, 

 mandibulis apice et antennis (articulis basalibus nonnullis 

 exceptis) nigris ; subtus nigra, lateribus metasterni medio et 

 abdominis apice ferrugineis ; pedibus ferrugineis ; capite 

 crebre sat crasse punctulato haud longitudinaliter impresso ; 

 prothorace quam longiori fere triple latiori, crebre subtilius 

 subaspere punctulato, ad latera paullo crassius punctulato 

 leviter impresso ; scutello punctulato ; elytris sat fortiter sat 

 crebre (quam prothorax minus crebre) punctulatis, interstitiis 

 crebre minute punctulatis, lineis longitudinalibus sublsevibus 

 vix manifesto notatis. Long., 3| — 4 1. ; lat., 2| — 3 1. 

 The shaj)e of the prothorax is characteristic ; looked down upon 

 from the point whence its length seems greatest the head has 

 almost the appearance of being inserted into a cavity formed by 

 three straight lines constituting the front margin of the pro- 

 thorax, and a line drawn across the greatest width of the pro- 

 thorax (where it is about half again as wide as across the tips of 

 the front angles) would fall scarcely behind its line of contact 

 with the back of the head ; the sides and base of the prothorax 

 form an almost continuously even curve ; the sides have a well- 

 defined thickened margin, inside which the lateral gutter is a 

 mere stria, and this thickened margin is quite defined all along 

 the front margin and base. The puncturation of both prothorax 

 and elytra is a little coarser and stronger near the lateral margins 

 than elsewhere. Looked at obliquely from the side the humeral 

 angle of the elytra appears much rounded off and the external 

 outline of the elytra appears as somewhat evenly and gently con-
