576 Mr. O. E. Janson's descriptions of 



coarsei" punctures at the sides and several large shallow impres- 

 sions. Scutellum almost concealed by the thoracic lobe, its 

 apex very acute. Elytra slightly transversely ■wrinkled and 

 finely punctured in longitudinal rows on the disc, the punctures 

 coarser and irregular at the sides and apex. Pygidium convex, 

 very finely strigose. Beneath punctured at the sides, meso- 

 sternal process very short, broad and rounded, abdomen 

 depressed; anterior tibiae with an obsolete tooth before the apex, 

 the intermediate and posterior tibins with a strong tooth in the 

 middle. Length 16-19 mm. 

 Mexico. 



Most nearly allied to C. sinaragdiiia, G.P., but of a narrower 

 and more convex form, different colour, shorter head, the 

 clypeus wider in front, with the central ridge shorter and more 

 elevated, the thoracic lobe pointed, and the pygidium more 

 swollen. 



Gymnetis spurca, n. sp. 



Above dull dusky, cinereous thoi-ax dull pitchy black, the 

 sides broadly cinereous, elytra clouded with dusky black in the 

 region of the scutellum and suture, the humeral callosity, two 

 small spots placed obliquely in the middle, and a V-shaped mark 

 behind dusky black, underside and legs shining black, irrorated 

 with cinereous. Head coarsely punctured, clypeiis rounded in 

 front, the apex slightly elevated and sinuous. Thorax much 

 narrower than the elytra at the base, with sparse coarse punc- 

 tures on the disc, which become closer and crescent shaped at 

 the sides. Elytra with the inner carina smooth and well 

 marked, the outer one obsolete, the disc with close roAvs of 

 coarse crescent shaped punctures, becoming confused and con- 

 fluent at the apex, the suture elevated and acutely produced at 

 the apex. Pygidium coarsely and closely strigose. Beneath 

 smooth in the middle, the sides with coarse crescent shaped 

 punctures, mesosternal process broad and obtusely rounded at 

 the apex; anterior tibia? with a small obtuse tooth before the 

 apex. Length 17 mm. 



Ecuador (Buckley). 



Allied to G. litnrata, Oliv., but easily distinguished by its 

 broader and more robust form and very coarse sculpture. 



Gijnmetis fumata, n. sp. 



Above dull smoky cinereous, elytra Avith a small rather ill- 

 defined pale luteous spot on the outer carina at about one-third
