Type locality. — Panama, Kepiiblic of Panama. 



Type^ allotype., and paratype. — U.S.N.M. No. 49551. 



Remarks. — Described from three examples (one male type). The 

 type was collected by Brother G. Regis; the male paratype, labeled 

 " Panama, 1917 ", is from the Wirt Robinson collection ; and the 

 allotype was collected near San Sebastian, Guatemala, by L. Thiel. 



This species resembles cyanitarsis Castelnau and Gory, but it 

 differs from that species in being much larger, in having the an- 

 terior margin of the epistoma deeply, arcuately emarginate, and in 

 having the emargination at the apex of the last abdominal segment 

 different. 



PARATYNDARIS MEXICANA, new species 



Male. — Robust, cylindrical, strongly acuminate posteriorly, uni- 

 formly black, with a vague purplish reflection in certain lights, and 

 each elytron ornamented with a large, rounded, reddish-yellow basal 

 spot, and with two similar spots along the lateral margin, one near 

 the humerus and the other at the middle. 



Head with the front nearly flat, and distinctly narrower at top 

 than at bottom; surface coarsely, densely punctate, and densely 

 clothed with long, semierect, whitish pubescence, which nearly con- 

 ceals the surface ; epistoma broadly, arcuately emarginate in front ; 

 antenna slender, very short, serrate from the sixth joint, and ex- 

 tending slightly beyond anterior margin of pronotum. 



Pronotum globose, slightly wider than long, widest at middle, 

 and the sides strongly, arcuately rounded; disk vaguely, longi- 

 tudinally depressed on basal half; surface coarsely, densely granu- 

 lose, and rather densely, uniformly clothed with rather long, semi- 

 erect, white hairs. Scutellum very small, narrowly oblong, and 

 nearly smooth. 



Elytra as wide as pronotum at base, the sides feebly, arcuately 

 expanded behind the humeral angles, then obliquely narrowed to 

 the tips, which are separately subtruncate and very coarsely, irreg- 

 ularly dentate; lateral margins coarsely, irregularly dentate on 

 apical halves ; disk moderately convex, feebly, longitudinally striate, 

 the striae punctate, intervals narrow, feebly convex, densely, rather 

 coarsely, irregularly punctate, rather densely clothed with moder- 

 ately long, semierect, white hairs, and each elytron with a longi- 

 tudinal row of short, erect teeth near the lateral margin on apical 

 half. 



Abdomen beneath vaguely granulose, coarsely, densely punctate, 

 and rather densely clothed with long, recumbent, white pubescence; 

 third segment with a broadly rounded, smooth, median lobe on the 

 posterior margin, the lobe projecting over the anterior part of the 

 fourth segment; last segment long, and strongly acuminate at apex; 

 pygidium densely granulose, and very coarsely, confluently punctate.
