HARPALIISLE 137 



rounded angles, slightly narrower than the base, which is very finely 

 margined, transverse medially but arcuate laterally, the angles 

 broadly obtuse and rounded; surface feebly convex, the fine lateral 

 reflexed edge equal throughout, the latero-basal area feebly de- 

 pressed, finely, closely punctate, the foveae short, shallow and broadly 

 impressed; stria strong, biabbreviated; elytra short, about a third 

 longer than wide, parallel, depressed, very obtuse at apex, much 

 wider than the prothorax, the sinus rather short and distinct, 

 deeper than usual; striae fine, the scutellar rather short, only feebly 

 oblique, the series distinct, the intervals flat, the polished surface 

 exhibiting somewhat the appearance of having minute sparse 

 punctulation which has become obsolete; tibia? and tarsi slender. 

 Length (cf 1 ) 6.1 mm.; width 2.5 mm. Florida (Lake Worth). 



depressulus n. sp. 



Form not so broad but depressed and otherwise nearly similar in colora- 

 tion, lustre and proportion of the parts, the elytra rather more 

 brilliantly opalescent; head not so short in form, the eyes relatively 

 even still larger, the antennae similarly long and slightly more slender, 

 the labrum darker; prothorax shorter, fully three-fifths wider than 

 long, the apex similarly rather strongly sinuate and barely visibly 

 narrower than the base, which is more rectilinear throughout, not 

 arcuate at the sides and with the angles similarly broadly obtuse and 

 rounded; sides similar; surface rather more flattened over the latero- 

 basal thickly punctured area, but with the foveae obsolete, the dis- 

 tinct median stria similar; elytra less broad, about two-fifths longer 

 than wide, much less obviously broader than the prothorax, similarly 

 parallel and obtuse at apex, the sinus distinct; striae fine but more 

 impressed, the intervals slightly convex, smoother and still more 

 polished and without any indication of minute suffused punctulation; 

 abdomen excessively minutely, sparsely punctulate, each punctule 

 bearing an extremely short erect hair, only visible by oblique illu- 

 mination; hind tarsi rather less elongate than in depressulus though 

 similar in structure. Length (cf) 5-5 mm.; width 2.0 mm. Florida 

 (locality and collector unrecorded) vigilans n. sp. 



6 Color deep black throughout, the reflexed thoracic edge not paler, the 

 legs piceous-black. Body oblong, rather strongly convex, highly 

 polished, the elytra with feeble blue-black lustre; head moderate, 

 three-fifths as wide as the prothorax, the eyes moderate, not very 

 convex, the foveae obsolescent as usual, the very slender antennae 

 and the palpi testaceous; prothorax rather long, subparallel, scarcely 

 a third wider than long, the sides broadly and evenly arcuate; apex 

 deeply sinuate, with prominent and rather narrowly rounded angles 

 and much narrower than the base, which is transverse and distinctly 

 margined, the angles nearly right but distinctly rounded; surface 

 with a very fine even reflexed edge throughout, the lateral surface 

 evenly convex and impunctate from apex to base, the foveae rather 

 large but extremely feeble and with a few distinct punctures; median 

 stria very fine but almost entire; elytra not evidently wider than the 

 prothorax, nearly one-half longer than wide, obtusely ogival at tip, 

 the sinus broad and feeble but evident; striae fine but rather deep,
