32 THOS. L. CASEY. 



abruptly acuminate, very feebly narrowed toward the base; maxillary palpi 

 long, first joint cylindrical, very minute, second at base as wide as the first, 

 much the longest, for three-fifths its length it is very narrow, cylindrical, 

 and bent upward slightly, then suddenly expanding into a flattened, sub- 

 securiform club, third joint nearly one-half as long as the second, strongly 

 flattened and broadly securiform, widest in the middle, fourth joint one-half 

 longer than the third, flattened, strongly securiform, widest slightly behind 

 the middle, where it is three-fifths as wide as long, surface thickly covered 

 with 8hort erect setae, from the immediate apex protrudes a long slender 

 spine ; labrum twice as wide as long, very convex, transverse anteriorly, 

 sides very strongly arcuate and parallel. Prothorax widest in the middle, 

 where it is slightly broader than long and wider than the head ; sides thence 

 very strongly convergent and feebly sinuate anteriorly, rather feebly con- 

 vergent and nearly straight posteriorly ; anterior margin three-fifths as long 

 as the base; disk very convex, highly polished, and impunctate. Elytra at 

 l)ase as wide as the prothorax ; sides moderately divergent posteriorly, nearly 

 evenly and rather strongly arcuate ; together broadly and transversely trun- 

 cate behind ; suture one-half longer than the pronotum ; disk evenly convex, 

 striae two on each elytra, sutural continuous throughout, medial abruptly 

 ending just before the middle ; surface highly polished, impunctate ; humeri 

 rather liroadly rounded. Abdominal segments arcuately and rapidly decreas- 

 ing in width, not as long as the elytra, strongly bordered ; surface highly 

 polished. First joint of posterior tarsi very short, second and third of equal 

 length. Length 1.5 mm,

Appears to be wklely distributed and not uncommon. Reitter, in 

 the " Insecten Deutschlands," says that the third joint of the maxil- 

 lary palpi in the genus Tyclius is '"■ very small, scarcely visible." 

 Tiiis is certainly not the case with the North American representa- 

 tives of the genus, as in all of our species, which I have examined, 

 the third joint is very fully developed, and in 7'. hngipalpus Lee. it 

 becomes nearly as long as the second joint. 



BRYAXIS. 



B. graciliti n. sp. — Form rather slender. Pubescence very long, rather 

 abundant, erect, setiform, pale fulvo-cinereous, prominent, less dense on the 

 pronotum. Head moderate, length from clypeus to base but very slightly 

 greater tiian width across the eyes, which are small, very prominent, and 

 nearly ht-mispherical ; genae distinct, equal in length to the eye ; interocular 

 surface moderately convex ; the three foveae are at the apices of an equi- 

 lateral triangle, they are prominent, almost exactly equal, circular, im- 

 pressed, and spongy at the bottom ; antennae as long as the head and pro- 

 thorax together, first joint indented above to fit the supra-antennal tubercle, 

 second joint very slightly smaller, remaining joints to the ninth more slender, 

 sub-cylindrical, equal in thickness, ninth slightly larger, very slightly
