144 MEMOIRS ON THE COLEOPTERA 



deeper black but with distinct aeneous lustre; legs piceo-testaceous; 

 head four-sevenths as wide as the prothorax, the eyes well developed 

 and prominent; antennae slender, fuscous, paler basally, extending 

 behind the thoracic base; prothorax four-fifths wider than long, the 

 sides almost evenly rounded, parallel basally, gradually converging 

 apically; apex deeply sinuate, three-fourths as wide as the base, 

 which is rectilinearly transverse; surface nearly even, without punc- 

 tures or foveae, the median stria distinct but only present medially; 

 elytra a third longer than wide, parallel, with slightly arcuate sides 

 and very little wider than the prothorax, evenly rounded in about 

 apical two-fifths, the sinus very feeble; striae very fine, the scutellar 

 short and oblique; intervals flat; anterior tarsi (cf 1 ) short, distinctly 

 dilated, the intermediate long, feebly dilated, the posterior very long 

 and slender, rather longer than the tibiae. Length (cf 1 ) 4.3 mm.; 

 width 1.75 mm. North Carolina (Southern Pines), Manee. 



contractus n. sp. 



6 Form rather narrowly oblong-oval, deep black, strongly shining (cf ), 

 rufo-piceous beneath, with paler epipleura, the legs testaceous; 

 antennae very slender, pale testaceous throughout, the palpi with the 

 usual coloration as in opacnlns; head short, subtransverse, slightly 

 more than half as wide as the prothorax, the foveae excessively 

 minute; eyes rather well developed and separated by but little more 

 than three times their length; prothorax fully three-fifths wider than 

 long, the sides gradually more converging anteriorly, the apex deeply 

 sinuate, rather more than two-thirds as wide as the base, which is 

 just visibly sinuate, the angles right, with their apices very narrowly 

 blunt; surface smooth, rather more steeply declivous anteriorly at 

 the sides to the fine reflexed edge than in the preceding species, the 

 edge rather more horizontal but less broadly expanding posteriorly, 

 though similarly disappearing near basal third or fourth; foveae not 

 wholly obsolete as in the four preceding but broadly lineiform and 

 evident, though short and very feeble; elytra a third to two-fifths 

 longer than wide, gradually rounding behind from near the middle, 

 the sinus barely traceable and vestigial, the striae fine, coarser apic- 

 ally as usual, the scutellar short and extremely feeble; intervals 

 flat. Length (cf) 5.0-5.6 mm.; width 1.8-2.2 mm. Texas (Gal- 

 veston). Five examples adjunctus n. sp. 



The above characters of ovalis Dej., are selected from the rather 

 diffuse original description; it is said by Horn that the surface 

 lustre is slightly iridescent, but I hardly think this term can apply 

 to such iridescence as is observed in the preceding genus, and it is 

 not alluded to by Dejean in his description. 



Selenophorus Dej. 



As a group of the Selenophorids, this genus is well distinguished 

 from either of the preceding by the much more convex form of the
