distinct from it. Tlie ornatnentation of the pronotum in fnnginns 

 does not consist of tubercles round and distinct as in longipennis, but 

 rather of very minute acute asperities at the roots of the hairs, and 

 in all my specimens these have a distinct arrangement in transverse 

 wavv lilies, more especially toward the middle of the disk. 



T. loilgipeiinis n. sp. — Form ratlier elongated ; sides parallel. Color 

 above piceoiis-blafk throughout ; legs, basal joints of the antennae, coxae, 

 and oral organs dark piceo-rufous ; remainder of antennae and under surface 

 piceous-black ; pubescence rather sparse, fine, slightly sericeous, piceo-cine- 

 reous. Head distinctly more than twice as wide as long, nearly transversely 

 truncate anteriorly ; surface smooth, strongly shining, minutely reticulated, 

 excessively minutely asperate at the roots of the hairs ; eyes ratlier large 

 and prominent ; labrum minute, very strongly inflexed, strongly rounded 

 anteriorly ; antennae nearly as long as the head and prothorax together, 

 slender, third joint two-tliirds as long as the fourth, remaining joints equally 

 thick, club large, very strongly compressed, eighth joint shorter and wider 

 than the seventh, last three joints abruptly much wider, nearly equal in 

 width, rapidly increasing in length. Prothorax widest slightly in advance 

 of tlie base, where it is about twice as wide as long ; base scarcely one-third 

 wider than tiie apex ; sides evenly divergent, evenly and rather feebly 

 arcuate throughout their length ; posterior angles not at all produced, 

 slightly obtuse and very slightly rounded ; base and apex transverse and 

 nearly straight ; disk strongly convex, very slightly inflexed at the sides, 

 finely rather strongly and evenly tuberculate, tubercles round, flattened, 

 without regular arrangement, interspaces strongly rugulose, shining ; finely 

 maigined along the sides ; just inside the posterior angles there is a very 

 feeble impression. Scutellum moderate, triangular, very slightly wider than 

 long, finely asperate. Elytra just visibly narrower than tht; pronotum ; sides 

 jiaialli'l and nearly straight, obliquely truncate behind ; exterior angles very 

 broadly rounded, interior distinctly rounded ; disk moderately convex, about 

 one-fifth longer than wide, two-thirds longer than the pronotum, finely and 

 feebly asperate, the points being arranged in oblique and irregular rows near 

 the suture, also finely and strongly rugulose and reticulated, shining. Legs 

 well developed ; anterior coxae globose and prominent, posterior lamellate, 

 strongly arcuate posteriorly, most strongly so near the raiddU of each, not 

 attaining the elytra. Last segment of the abdomen equal in length to the 

 three preceding together. Length 0.9 mm. 



Philadelphia, Fairmount Park, 3. 



Found in fungous earth under fallen leaves in a wooded ravine. It 

 differs from fnnginns in its more elongate narrow form, in the nature 

 of the pronotal sculpture, and very markedly in tiie nature of tlie sides 

 and posterior angles of tlu^ pronotum ; the posterior coxae are sligiitly 

 longer and more regularly arcuate In-hind. The antennal club is so 

 strongly compressed, that viewing it from above tlie antenna a|)pt'ars 

 to be attenuated and without a vestige of club; laterally, however, 

 the club is seen to be unusually strong.
