by the regularly oval, deeply striate elytra, without distinct 

 humeral angles, though the base is slightly emarginate, and 

 the basal fold meets the margin in a well-defined angle ; the 

 dorsal punctures are three — the first on the third, the other 

 two on the second stria ; the wings are not developed. The 

 prothorax is quadrate-ovate, narrowed behind, scarcely wider 

 than long, with the sides strongly but not widely margined, 

 and subsinuate behind; the hind angles rectangular, not rounded 

 in five specimens, feebly rounded in a sixth ; the base is ti'un- 

 cate, finely margined, somewhat oblique at the sides near the 

 angles ; the transverse impressions are well marked, and the 

 basal impressions are deep and not punctured. The under 

 surface of the joints of the front tarsi of the ^ are clothed 

 with long golden-yellow hair; the front tarsi are without 

 grooves ; the middle and hind tarsi have a distinct exterior, 

 but no interior groove.

^neo-niger, nitidus, alatus ; protliorace fotundato-quadrato, postice 

 paiilo angustiore, latitudine vix breviore, lateribus et basi late

 tusis, subrotundatis, licet sat distiuctis, basi utrinque late im- 

 pressa et subtiliter rugosa; elytris clougato-ovalibus, thorace 

 paulo latioribus, striis subtilibus baud puuctatis, puuctis 3 dor- 

 salibus, l""o in 2"% alteris in stria 3'^ sitis.

One female. This species appears more nearly allied to P. 

 Harrisii, Lee, than to any other in my collection, but differs 

 by its much smaller size and by the absence of the impression 

 near the posterior end of the fifth stria. It resembles in the 

 form of the prothorax P. f rater, Lee.*, but is smaller, and has 

 the second dorsal puncture on the second stria, while in that 

 species it is on the third. 



y Zacotus, no v. gen. (Broscini). 

 y^ Zacotus Matthewsn. 

 Supra piirpureo-cupreus, nitidus, subtus niger ; capite obscure cu- 

 preo, fronte profuude impresso, lateribus et inter oculos valde ru- 

 goso ; prothorace convexo, ovato, latitudine paulo longiore, postice 

 augustato et peduneulato, lateribus versus basin sinuatis, linea dor- 

 sali profunda, impressionibiis transversis parum distiuctis ; disco 



* I am informed by Baron Cliaudoir that P. f rater, Lee, is the same 

 as Agonum brevicolle, Dej. iii. 159. The latter, however, is described as 

 having four dorsal punctures, while in many specimens of P. f rater which. 

 I have examined I perceive but three. I am therefore inclined to believe 

 that Dejean's species is only an individual variation of P. fossiger.
