AMERICAN COLEOPTERA. 83 



striate, striae coarsely punctured especially near the apex, intervals slightly 

 convex, densely punctate. Length .48— .80 inch, .909; 12—20 mm, 22.59. 

 PI. II, fig. 7. 



The thorax is very variable in shape and convexity — usually nearly 

 square slightly narrowed in front, sometimes slightly transverse, the hind 

 angles are never strongly divergent. The disc may be either normally 

 convex or variously impressed. The mandibles when closed leave but a 

 small open space between them and the labrum. 



C mandibularis Lee. (^nacAt7i<s). ^Moderately elongnte, fusco-testaceous, 

 sparsely pubescent. Head piceous or nearly black, moderately densely punctate. 

 Labrum transverse, feebly emarginate, usually pale in color, either connate with 

 the front without suture or with the suture more or less distinct. Mandibles 

 slender, prominent, and when closed leaving a wide open space between them. 

 Antennae moderately serrate, terminal joint deeply constricted at tip. Thorax 

 broader than long, sides moderately arcuate, hind angles acute, divergent, surface 

 moderately densely punctate. Prosternum extremely narrow between the coxae. 

 Elytra a little broader than the thorax, deeply broadly striate, striae coarsely 

 punctured especially near the apex, intervals densely punctulate. Body be- 

 neath paler than above and moderately densely punctate. Length .44 — .54 inch ; 

 11— 13.5 mm. 



Of this species we know males only. 



Occurs in Florida. 



C estriatns n. sp. — Moderately elongate, pale brownish testaceous, finely 

 pubescent. Head moderately densely punctured. Labrum transverse, feebly 

 emarginate, suture distinct. Mandibles rather short, when closed not leaving a 

 space between them. Thorax nearly square, sides feebly arcuate, hind angles 

 short, acute, divergent, surface not densely punctate. Prosternum very narrow 

 between the coxae. Elytra a little wider than the thorax, surface not striate but 

 densely punctate and with faint traces of three discal costae. Body beneath not 

 densely punctate. Length .44 inch; 11 mm. 



The antennae are less serrate than in the two preceding species and the 

 terminal joint is not constricted, this character with the absence of elytral 

 striae will serve to distinguish it. 



One specimen, Texas. 



SCAPTOI.ENITS Lee. 



The species of this genus which occur in our fauna are from Texas. 

 In the Annales de la Societe Entom. de France, 1874, p. 523, Chevrolat 

 cites <S. 6r(2^^«^■ from Texas ? and p. 524, *S'. GaUfornicus from California, 

 while in the list of species p. 509, both are quoted from Mexico. I have 

 no doubt that they are really Mexican. 



Three species are otherwise known to me. 



Last joint of maxillary palpus as long or longer than the preceding. Last joint 

 of labial palpi longer. 

 Elytra rather deeply sulcate and suhcostulate liCCOntei Salle.
