angles obtuse, prominent, and not at all rounded, setigerous ; anterior angles 

 rather broadly rounded ; base and apex about equal in length, transverse 

 and nearly straight ; disk convex, more strongly so toward the anterior 

 angles ; lateral setae at two-fifths the length from the apical angles ; border 

 narrowly retlexed , median groove very fine and feeble, extending from the 

 base nearly to tlie apex ; very near the base there is a broadly arcuate im- 

 pressed groove entirely interrupted in the middle, but coarsely and feebly 

 punctate toward the sides, tuberculatlon near each basal angle extremely 

 feeble. Scutellum very small, distinctly wider than long, angulate behind, 

 sides rounded, slightly constricted at base. Elytra at base scarcely wider 

 than the pronotum ; sides parallel and moderately arcuate for nearly two- 

 thirds the length, thence convergent ; disk rather acutely rounded behind, 

 widest at about one-third the length from the base, where it is two-thirds 

 longer than wide, strongly convex ; sutural striae fine, strong, feebly arcuate, 

 with distinct traces of a second stria; each elytron has on the disk two 

 minute setigerous punctures as in g/ossema, and, at the base, a circular 

 setigerous verrucation near the scutellum ; edges narrowly reflexed ; humeri 

 broadly rounded, near wliich there is a short irregularly impressed channel 

 having four small setigerous punctures nearly equidistant and scattered 

 along its entire length ; there is also a large setigerous puncture posteriorly 

 at the edge ; epipleurae wide at the basal third, where the inferior edge is 

 feebly sinuate. Abdomen feebly convex ; terminal segment with two apical 

 pairs of setae. Legs long and slender ; posterior trochanter with one discal 

 seta; posterior femora with three equidistant erect setae. Length 2.4 mm.

Taken under rubbish on the sea-beaeh ; it resembles at first sight 

 incinriis, but differs greatly in tlie color, want of elytral maculations, 

 niueli more slender form of body, opatiue integuments, and many 

 minor eliaracters, among wliicli may be mentioned the transversely 

 arcuate furrow at the base of the pronotum, which is densely and 

 evenly foveate throughout its length in inciirvus.

 extremely minutely and irregularly punctate more especially toward tlie 

 eyes, polished, with brilliant and varied metallic red and green reflections ; 

 labrum and maiidihles black, the former four-fifths wider than long, almost
