332 PROCEEDINGS OF THE NATIONAL MUSEUM vol.99 



Elytra at base as wide as pronotum at base; sides parallel from 

 bases to middles, then arcuately converging to the tips, which are 

 separately broadly rounded or subtruncate ; lateral margins not ser- 

 rate, but with a large tooth near apices; disk moderately, uniformly 

 convex ; surface more or less distinctly, longitudinally costate, coarsely, 

 densely punctate, the punctures arranged in double rows between the 

 costae, rather densely, irregularly clothed with short, recumbent, 

 whitish hairs. 



Abdomen beneath finely, densely, uniformly punctate, impunctate 

 along posterior margins of sternites, densely, uniformly clothed with 

 moderately long, recumbent and semierect, white hairs ; posterior mar- 

 gin of second sternite truncate ; last visible sternite depressed on each 

 side of middle, and terminating in an acute spine. 



Length 8.5-10.5 mm., width 3.5-4.5 mm. 



Ty^pe locality. — Piura, Peru. 



Type and paratype.—V.S.'NM. No. 58785. 



Described from two sepcimens (one type). The type was collected 

 at the type locality and the paratype was collected at Lullana, Peru, 

 both by C. H. T. Townsend. 



This species is allied to Tyndaris marginella Fairmaire, but it differs 

 from that species in being uniformly brownish black, without any 

 yellow spots, and in having the elytra distinctly costate with the coarse 

 punctures arranged in double rows between the costae. 



TYNDARIS REEDI, new species 



Short, robust, rather strongly shining ; head and pronotum cupreous, 

 the latter with five small, round equally spaced orange-red spots along 

 anterior margin ; elytra black with a vague brownish tinge, and each 

 elytron ornamented with four or five small orange-red spots, two at 

 base, one at humeral angle, one at middle equally distant from sutural 

 and lateral margins, and sometimes one at apical third a short distance 

 from sutural margin; body beneath black, with distinct purplish, 

 greenish, or bronzy reflections in different lights. 



Head feebly, uniformly convex, longitudinally carinate on vertex 

 and occiput, without a median depression; surface coarsely, densely 

 punctate on front, confluently punctate on occiput, sparsely clothed 

 with short, recumbent, whitish hairs; intervals smooth; epistoma 

 broadly, shallowly, arcuately emarginate in front; antenna serrate 

 beginning with fifth segment. 



Pronotum very strongly, uniformly convex, slightly wider than 

 long, distinctly narrower at apex than at base, widest at middle ; sides 

 strongly arcuately rounded; lateral margin when viewed from side 

 entire and slightly arcuate ; base sinuate on each side, the median lob© 

 strongly produced and vaguely emarginate in front of scutellum;
