CICINDELID.E AND CARABID^: 151 



Dicaelus subtropicus n. sp. Small in size, rather narrowly oval, deep 

 black and opaque throughout; head rather short, evidently more than 

 half as wide as the prothorax, smooth, the obsolete rugulosity excessively 

 minute, the anterior impressions distinct, prolonged obliquely along the 

 sides of the epistoma; antennae rather short, filiform, not attenuated but 

 brown distally; prothorax a third to fourth wider than long, parallel, 

 arcuately and moderately narrowing apically, the median part of the 

 base more than half the maximum width and feebly sinuate; surface 

 nearly flat, rather narrowly but distinctly reflexed at the sides, gradually 

 a little more broadly basally, the edge even and fine throughout, having, 

 near inner two-fifths and basal third at each side, a fine longitudinal im- 

 pressed line, extended by broad and feeble impression obliquely to the 

 base near lateral fourth, and also anteriorly for a long distance, the basal 

 and apical transverse impressions almost obsolete; median stria fine but 

 evident; lustre opaque, the sculpture excessively minute and not distinct, 

 not at all rugose; elytra but very slightly wider than the prothorax, two- 

 fifths ( 9 ) to one-half (cf) longer than wide, more gradually and less 

 obtusely rounded behind in the latter sex, the sides feebly arcuate; striae 

 very deeply impressed, finely but very distinctly punctate; intervals 

 strongly convex, the alternate ones distinctly broader and more convex 

 but not at all cariniform, the humeral carina acute but only moderately 

 prominent, gradually obtuse and obsolescent posteriorly. Length 

 13.0-14.5 mm.; width 5.0-5.7 mm. Florida (Palm Beach), Kinzel. 

 Six examples. 



Differs from both ovalis and furvus in its narrower form, thoracic 

 impressions and alternately distinctly wider and more convex strial 

 intervals, also in the evidently punctate striae, the punctures later- 

 ally somewhat indenting the sides of the intervals, as in crenatus 

 though less strongly. 



Dicaelus debiliceps n. sp. Elongate and slender, subopaque, deep black 

 throughout; head smaller than in any other species, less than half as 

 wide as the prothorax, smooth and rather shining, the sculpture vestigial 

 and faint; anterior impressions deep, oblique; antennae slender, filiform; 

 prothorax not distinctly shorter than wide, the sides broadly, subevenly 

 arcuate, converging a good deal anteriorly, becoming parallel toward base, 

 the surface throughout and the two anterior marginal punctures nearly 

 as in elongatus and simplex, the apex relatively more narrowed than in 

 either; elytra two-thirds longer than wide, gradually arcuately narrowing 

 behind from near the middle, at which point they are very slightly wider 

 than the prothorax, moderately convex, the striae rather fine and only 

 very moderately deep, the intervals equal and broadly, feebly convex, 

 the humeral carina as in elongatus. Length ( 9 ) 14.7 mm. ; width 5.65 mm. 

 Pennsylvania (Buena Vista Spring, Franklin Co.). 



This species belongs to the elongatus series and resembles it closely 

 in general characters, but it is smaller and very much more slender, 

 with a relatively still smaller head and more equal and very much
