ClCINDELID.E AND CARABID.E 57 



Carabus lecontei n. sp. Stout, convex, strongly shining and feebly 

 sculptured, deep black, the elytral margins strongly and the broad 

 thoracic margins more feebly bluish; head two-fifths as wide as the 

 prothorax, the anterior impressions at the sides of the epistoma deep; 

 antennae rather long, black, the fifth joint not quite three times as long 

 as wide; prothorax large, transverse, four-fifths as wide as the elytra, 

 nearly one-half wider than long, the sides subparallel, broadly, feebly 

 rounded anteriorly, thence just visibly converging and nearly straight 

 to the rounded basal angles, which are very broadly but feebly produced 

 posteriorly, the median truncate part of the base equal to half the maxi- 

 mum width; surface broadly convex, smooth and wholly punctureless, 

 except in the broadly concave side margins, which become very broad 

 and deep basally, the smooth lateral edges very thick; anterior impassion 

 obsolete but with a very few faint punctures, the transverse basal 

 impression conspicuously deep and punctured; median stria fine, entire; 

 elytra not quite one-half longer than wide, oval, slightly broader behind 

 the middle, evenly and strongly convex, rather broadly reflexed at the 

 sides, having close-set unimpressed series of very fine, well spaced punc- 

 tures, which become coarser and altogether confused on the flanks, also 

 having three series of deep non-metallic foveae; hind tarsi much longer 

 than the tibiae; under surface and legs deep black throughout, except 

 the side-pieces of the prosternum, which are violaceous. Length 24.0 

 mm.; width 10.7 mm. Texas. A single female example. 



The type formed a part of the Levette collection and has puzzled 

 me for many years; it is related to sylvosus Say, but differs in the 

 much larger and broader prothorax with less rounded and less 

 basally converging sides, distinct median stria and deeper basal 

 transverse impression of the latter and relatively shorter elytra, 

 having the series of punctures wholly unimpressed. 



Carabus patulicollis n. sp. Elongate, subparallel, rather strongly 

 convex, shining, piceous-black, piceo-rufous beneath probably im- 

 mature, the legs and antennae black; head half as wide as the prothorax, 

 with very prominent eyes, finely punctured and rugulose basally, the 

 vertex longitudinally and closely plicate toward the eyes, the impressions 

 at the sides of the epistoma deep, very smooth and polished; antennae 

 three-fifths as long as the body; prothorax transverse, nearly one-half 

 wider than long., fully three-fourths as wide as the elytra, with broad 

 flat polished vermicular rugae throughout and with a few fine scattered 

 punctures sublaterally, becoming gradually coarse, dense, punctured 

 rugae in the lateral concavity and in about lateral fourth of basal half, 

 where there is a broad feeble longitudinal impression at outer fourth; 

 margins fine, broadly and moderately reflexed basally, more abruptly 

 anteriorly, widest a little before the middle, the sides broadly rounded, 

 distinctly converging and straight in about basal half to the rounded and 

 posteriorly produced angles, the base wider than the apex, the truncate 

 part rather more than half the maximum width; surface without anterior 

 or posterior transverse impressions, the median stria fine but distinct;
