the type of Ischyrus. In other ways, also, it differs so profoundly 

 from Ischyrus, as to excite surprise that its essential differences 

 were apparently unnoticed by Mr. Crotch. The last joint of the 

 maxillary palpi is very strongly dilated and transverse and the tibiae 

 are triangular, both of which characters are at radical variance with 

 those of Ischyrus. The antennal shaft is very much more slender 

 and the 3-jointed club smaller, shorter and still more compact. Of 

 Pseudischyrus brunneus Lac., I have a good series, taken at Palm 

 Beach, Florida; it agrees very well with the original description 

 but, when mature, is deep black above, with the head pale brown 

 and the pronotum nubilously piceous toward the sides and apex 

 as stated, the under surface piceous-black, the prosternum, meta- 

 parapleura, legs and antennas pale; it varies very much in the size of 

 the body 2.4-4.4 rnm. The following is an evident additional 

 species of the genus: 



Pseudischyrus acuminatus n. sp. Elongate-subrhomboidal, strongly 

 convex, black above, the pronotum nubilously pallescent toward the 

 apical angles, the head brown; under surface, legs and antennae colored 

 nearly as in brunneus (nigrans), the pale parts of the surface more obscure, 

 the elytra feebly alutaceous; head nearly half as wide as the prothorax, 

 minutely, evenly and sparsely punctate, the eyes very coarsely faceted; 

 antennae small, not as long as the prothorax, the basal joint large and 

 cylindric, the second small and subglobular, the shaft very slender 

 basally, increasing in thickness distally, the third joint very slender, 

 longer than the next two; club barely more than half as long as the re- 

 mainder, oblong-oval, rather compact, the joints much wider than long; 

 prothorax much longer than in brunneus, but little over one-half wider 

 than long, the sides nearly straight, moderately converging from the 

 base, slightly more arcuate anteriorly; apical angles rather blunt but 

 anteriorly prominent, the apex transverse between them; base gradually 

 and strongly lobed medially, finely margined except on the lobe; punc- 

 tures very minute, sparse, less sparse but not distinctly larger laterally; 

 scutellum slightly wider than long, broadly angulate behind, very finely, 

 rather sparsely punctate; elytra about three-fourths longer than wide, 

 two and two-thirds as long as the prothorax and, at basal third or fourth, 

 distinctly wider than the latter, the sides evenly arcuate, gradually strongly 

 converging to the apex, which is very much more narrowly rounded 

 than in brunneus, the apex feebly and nubilously pallescent; punctures 

 very fine, moderately close-set in very even, unimpressed and entire 

 series, becoming feebly impressed laterally, the intervals sparsely, evenly 

 and excessively minutely punctulate; abdomen finely, sparsely punctate, 

 the flat triangular tibiae asperately punctulate. Length 3.8 mm.; 

 width 2.0 mm. Florida (Lake Co.).
