fine, groove-like, very finely, closely punctate, the seventh distinct

 mm.; width 2.5-2.6 mm. Florida (Sarasota), Blatchley. 



celer Dej. 



Body shorter, more ventricose and rather more convex, polished, black, 

 more piceous beneath, the tarsi dull rufous; elytra moderately iri- 

 descent; head slightly elongate, with large and rather prominent 

 eyes, almost three-fourths as wide as the prothorax; antennae pice- 

 ous, paler basally; prothorax smaller and narrower than in the pre- 

 ceding, barely a fourth wider than long, the parallel sides very evenly, 

 moderately arcuate and finely, diaphanously reflexed; apex moder- 

 ately sinuate, with bluntly rounded angles, slightly narrower than 

 the base, which is margined except medially, not rufescent at the 

 middle; incised apical line very fine, obsolete medially; subbasal 

 punctures few; foveae deep, attaining the base; impressions obsolete; 

 elytra shorter and more oblong-oval, scarcely one-half longer than 

 wide and three-sevenths wider than the prothorax, more regularly 

 rounded behind in apical two-fifths, the sides gradually more arcu- 

 ate basally; subapical sinus shorter and distinct; reflexed margin 

 rufous; striae rather fine but more impressed, the punctures much 

 more distinct, minutely crenulating the intervals, which are slightly 

 more convex; seventh stria evident throughout, though merely a 

 series of fine punctures except apically. Length ( 9 ) 7.0 mm.; width 

 2.4-2.5 mm. Florida (Dunedin), Blatchley concinnus n. sp. 



The species named lateralis above, I received under the name 

 reflexus Lee., but there are only five discal striae on the elytra, the 

 sixth and seventh barely traceable, and, if such a remarkable and 

 wholly exceptional character as this exists in reflexus, from Tampa, 

 it surely would have been mentioned by the describer. Again the 

 elytra in reflexus are said to be not wider than the prothorax; this 

 is in all probability not rigorously true, as the hind body is always 

 at least somewhat wider than the prothorax in this genus, but the 

 language used seems to show that the difference in width in the 

 case of reflexus must be very slight; it is very pronounced in later- 

 alis. LeConte, although laying considerable stress upon the par- 

 tial obliteration of the incised line along the apical thoracic margin 

 in crenatus and tceniatus, unaccountably makes no allusion to the 

 still more complete obliteration of this line in saphyrinus; it is simi- 

 larly obsolete in lateralis and presumably also in reflexus, being, in 

 the case of these larger species, to some extent correlated with the 

 basally broadly reflexed sides of the prothorax. 



Some of the small species above described, such as suturalis and 

 cervicalis, are apparently rather closely allied to velox Dej., but the
