15 Pronotum narrowly deplanate at the sides basally. Elongate-sub- 

 oval, rather strongly convex, very shining, deep black, the tarsi 

 rufous; anterior tibiae paler than the others; elytra without any very 

 obvious trace of iridescence; head small, with long neck and well 

 developed eyes, four-sevenths as wide as the prothorax; mandibles 

 black, the palpi pale; antennae nearly black, testaceous basally; 

 prothorax nearly a third wider than long, the sides very evenly, 

 moderately rounded; apex sinuate, distinctly narrower than the base, 

 the incised line deep, the stria deep and almost entire; base margined 

 except medially, the angles broadly obtuse, rounded; anterior im- 

 pression obsolete, the posterior feeble, the medio-subbasal punctures 

 evenly scattered and distinct; foveae deep, not quite attaining the 

 base; elytra one-half longer than wide, fully a fourth wider than the 

 prothorax, arcuately narrowing behind the middle, the sides feebly, 

 subequally arcuate to the base, the sinus short, unusually deep; 

 striae somewhat coarse, strongly and conspicuously, subcrenalately 

 punctate, the seventh obsolete basally; intervals rather strongly 

 convex. Length (9 ) 7-6 mm.; width 2.75 mm. Florida (Dunedin), 

 Blatchley cursitans n. sp. 



Pronotum not deplanate at the sides basally 16 



16 Form rather stout and subventricose, highly polished, deep black, 

 the tarsi paler; elytra feebly iridescent; head elongate, with prom- 

 inent eyes and long neck; mandibles blackish throughout; antennae 

 fuscous, testaceous basally; prothorax barely a fourth wider than 

 long, the sides very evenly, moderately arcuate; apex moderately 

 sinuate, evidently narrower than the base, which is finely margined 

 laterally and with broadly obtuse rounded angles; apical incised 

 line very fine and feeble, interrupted at the middle; impressions fee- 

 ble, the stria very fine; medio-subbasal punctures almost wanting; 

 foveae narrow and deep, distinctly separated from the basal margin; 

 elytra one-half longer than wide, fully two-fifths wider than the 

 prothorax, rather rapidly, arcuately narrowing in about apical third; 

 sides slightly more arcuate basally, the subapical sinus short and 

 notably shallow; striae rather fine but well impressed, the punctures 

 distinct and subcrenulate but not coarse; seventh stria obsolete bas- 

 ally; intervals broadly convex. Length (9) 8.6-9.5 mm.; width 

 3.4-3.5 mm. Florida (Dunedin), -Blatchley comptus n. sp. 



Form much narrower, not so ventricose and not quite so convex, simi- 

 larly colored, the elytra feebly iridescent; head barely at all elon- 

 gate, with large prominent eyes and moderate neck, nearly two- 

 thirds as wide as the prothorax; mandibles obscure rufous, blackish 

 distally; antennae piceous, testaceous basally, the palpi pale; pro- 

 thorax a fourth to third wider than long, the parallel sides evenly 

 and rather strongly arcuate; apex rather deeply sinuate, much nar- 

 rower than the base, with but slightly blunt prominent angles and 

 very fine and feeble though entire incised line; base finely margined 

 laterally, with broadly obtuse and rounded angles; impressions both 

 feeble, the stria very fine, biabbreviated, the medio-subbasal punc- 

 tures minute, few or wanting; foveae narrow, deep, far from attain- 

 ing the base; surface very feebly declivously flattened postero-lat-
