436 TROGOSITIDA. 
50. Tenebroides fulgens, sp.n. (Tab. XIII. fig. 24.) 
Niger, nitidus, supra capite prothoraceque «neo-auratis, elytris purpureis. 
Long. 47 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne black, with extremely large club. Head rather small, convex, moderately 
coarsely punctured. Thorax of a golden-brassy colour, very shining, somewhat 
sparingly punctate, rounded at the sides and narrowed behind, the front angles a little 
prominent, the lateral margin crenulate, the basal margin uninterrupted. Elytra with 
series of punctures, viewed from the outside appearing striate, of a beautiful metallic 
purple colour, very shining. Ventral segments sparingly and obsoletely punctate. 
Allied to 7. politus, though very different in colour. M. Léveillé informs me that it 
also approaches 7’. gownellei, Lév. Only one specimen has been received. 
51. Tenebroides merens, sp. n. 
Minutus, niger, nitidus, antennis pedibusque rufo-obscuris ; prothorace basin versus angustato. 
Long. 3 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Antenne thick, dark red, the two joints preceding the club transverse, the joints of 
the club adpressed and with very small sensitive aree. Head narrow, convex, some- 
what closely and coarsely punctured. Thorax rather narrow, much narrowed behind, 
the front angles scarcely at all produced, the lateral and basal margins very fine, the 
latter uninterrupted ; the surface somewhat sparingly punctate. Llytra shining, 
obscurely striate, with scarcely visible interstitial punctuation. 
Only one specimen has been received of this distinct little species. It differs greatly 
from T. politus and T. fulgens in the structure of the antenne. 
52. Tenebroides zapotensis, sp.n. (Tab. XIII. fig. 25.) 
Parvus, subcylindricus, niger, antennis elytrisque rufis, his ad apicem nigris, pedibus piceis. 
Long. 44 millim. 
Hab. Gvaremata, Zapote (Champion). 
Antenne red, stout, the three joints of the club broad, but adpressed, their sensitive 
are: small. Thorax quadrate, transversely convex, straight at the sides, truncate in 
front, with the anterior angles not at all produced, the lateral margin as fine as the 
basal margin, the latter not interrupted in the middle; the surface coarsely punctate. 
Elytra bright red, broadly black behind, with regular series of impressed punctures, 
the lateral series very fine but quite distinct, the interstices finely but distinctly punc- 
tured. Legs broad, the middle tibiee with two spinules on the outer edge. 
Only one specimen was obtained of this very distinct species; in size and appearance 
it resembles a Corticeus (Hypophlwus), a genus of Tenebrionide.
