54 TIIOS. L. CASEY. 



aiigiilate posteriorly, and at the apex there is a very deeply impressed, 

 posteriorly bifurcated puncture ; antennae slightly longer than the width of 

 pronotum, basal joint moderately robust and elongated, second less robust 

 and shorter, joints three to six slender, sixth much the. shortest, joints 

 seven to eleven enlarged as a very elongated compact cylindrical club, 

 darker in color. Prothorax nearly twice as wide as long ; sides nearly 

 parallel and feebly arcuate ; base rather strongly arcuate and very feebly 

 sinuate near the basal angles, which are acute ; apex broadly and evenly 

 arcuate ; disk narrowly mai-gined posteriorly, finely, evenly, and very con- 

 spicuously reticulated, also strongly, evenly, and rather distantly punctate ; 

 in the middle there are four distinct impressions at the corners of a square ; 

 just inside the posterior margin there is a transverse row of very large deeply 

 impressed punctures. Elytra three times as long as the pronotum, rather 

 acutely rounded behind ; disk minutely reticulated, though not as distinctly 

 as the pronotum, very strongly punctate, punctures large, very deeply im- 

 pressed and arranged in striae-like rows, fifth and sixth rows discontinuous. 

 Prosternum broadly and roundly emarginate anteriorly ; distance of front 

 coxae from the emargination equal to one-half the distance between them. 

 Length 1.8 mm. 



Willets Point, Long Island ; one specimen. 



This is a somewliat remarkable species ; the front coxae are more 

 widely separated than usual. '1 he specimen described above is slightly 

 immature, thus causing a warping of the elytra after drying ; the 

 exact form of these parts cannot tlierefore be exactly stated. 



PSIXLIODES. 



P. extricata n. sp. — Form elongated, narrowed behind, somewhat 

 depressed ; body glabrous, shining, brassy-bronze above, much more piceous 

 beneath. Head convex, moderate in size ; interocular surface almost con- 

 tinuous in convexity with the eyes, nearly twice as wide as the latter, feebly 

 and evenly punctulate and minutely granulated ; eyes not at all prominent ; 

 labruni one-third wider than long, roundly and feebly emarginate in the 

 middle anteriorly, anterior angles rounded, surface with two feeble approxi- 

 mate setigerous impressions in the middle ; antennae moderate, testaceous at 

 base, piceous toward the tip where they are thickly pubescent, joints two, 

 three, and four uniformly and rapidly increasing in length, fifth much 

 shorter, sixth slightly longer than the fifth. Prothorax twice as wide as 

 long, base one-third longer than the apex ; sides nearly straight ; base and 

 apex broadly, evenly, rather strongly, and nearly equally arcuate ; posterior 

 a ngles atute turn above; disk finely and evenly unctulate, and finely 

 reticulated, punctures separated by about five times their own widths ; base 

 narrowly and evenly margined. Scutellum sub-triangular, sides arcuate, 

 broader than long. Elytra at base as wide as the prothorax ; sides rather 

 strongly arcuate and convergent posteriorly ; disk four times as long as the 

 pronotum, acutely rounded behind, strongly punctate : punctures deeply 

 impressed and arranged in striae-like rows, distance between the rows greater 

 than the distance between the punctures in the rows ; surface also minutely
