lation. First joint of the posterior tarsi short, extremely obliquely truncate 

 at tip. Length 3.3-i.tJ min. 



Sea-beaclies of New Jersey, 8. 



A common littoral species, distinguislied by its pale color, very 

 narrowly oval form and punctuation. Tlie last three joints of the 

 antennae forming the club <ire abruptly nearly black, all the preced- 

 ing joints being very pale ; the sixth joint, although nearlv as wide 

 at apex as the succeeding ones, does not in my opinion form part of 

 the club.

C decoi'is n. sp. — Form regularly elliptical, nearly two and one-half 

 times as long as wide ; very convex ; head piceous ; prothorax paler, piceous- 

 brown, hind angles and base gradually paler from diaphaneity : elytra pale 

 ochreous-yellow, under surface and legs same ; antennae dark reddish-brown, 

 very slightly pal(U- toward base and at the tip; pubescence pale yellowish, 

 dense and coarse on the elytra, more fine and sparse on the pronotum. Head 

 strongly deflexed, as wide as long, rather densely pubescent; eyes rather 

 large and prominent, sparingly setose ; interocular surface feebly and evenly 

 convex, polished, coarsely, very deeply and evenly punctate; punctures 

 round, so deep as to appear like perforations, slightly narrower than the 

 interspaces, finer and more close toward the labrnm, which is small, trans- 

 verse, and constricted slightly at base ; antennae short, slightly longer than 

 the width of head, club very prominent, four-jointed ; third joint equal in 

 length to the second, slightly thinner, longer than wide, fourth scarcely 

 longer than wide, as thick as the third, fifth trapezoidal, twice as wide as 

 long, shorter than the fourth, sixth and seventh very short, trapezoidal, 

 nearly three and four times as wide as long respectively, eighth longer than 

 the two preceding together, trapezoidal, one-third wider than long, joints five 

 to eight gradually and connectively increasing in width to the apex of the 

 eightli, where the club reaches its maximum thickness, and is thence cylin- 

 drical and very compact to the tip, ninth and tenth equal, shorter than the 

 eighth, about twice as wide as long, eleventh wider than long, very broadly 

 rounded at tiji. Prothorax widest at two-thirds its length from the apex, 

 where it is nearly one-half wider than long ; sides thent-e just visibly con- 

 vergent posteriorly, more strongly convergent anteriorly, nearly evenly 

 arcuate throughout ; apex broadly arcuate, three-fifths as long as the base, 

 which is broadly and very feebly arcuate, ahrujttly slightly more strongly 

 so toward the midtlle ; basal angles obtuse and not rounded; disk strongly 

 convex, coarsely, strongly, and sub-variolately punctate, punctures very 

 irregularly and loosely scattered, at many spots arranged in very straggling 

 broken series, interspaces finely and feebly punetulate, polished. Elytra at 

 base as wide as the pronotum; sides parallel for three-fifths the length from 

 the humeri, thence gradually convergent behind, obtusely rounded at the 

 immediate apex ; disk strongly convex, widest at alwut one-third its length 

 from tiie humeri, where it is fully three-fourths huiger than wide, with the
