FALL AND COCKERELL. 233 



this is scarcely evident in my examples. In luteipennis the lateral 

 margin of the hind angles is represented by a very fine, short carina, 

 the true margin taking the form of a short inferior subniarginal 

 raised line nearly as in Cardiophorus. This inferior line is appar- 

 ently totally absent in calif ornietis. Only males are known to me 

 in this genus, the genitalia being virtually identical in the two 

 species. 



Cebrio COinpositus n. sp. — Dark brown, abdomen somewhat paler, legs 

 and antennae rufotestaceons. Head rather finely but not densely punctate, the 

 punctures distant by nearly their own diameters as a rule; prothorax sparsely 

 very finely punctate, the punctures separated on the average by three to four 

 times their own diameters ; elytra striate as in 6ico?or and mandibularis. Mandi- 

 bles moderately prominent, nearly as in hicolor ; labrum deeply sinuate, appar- 

 ently subconnate with the front but with distinct suture. Antennse slender, 

 feebly serrate ; second joint one-half tlie length of the third, the latter a little 

 more than half as long as the fourth ; terminal joint rather abruptly pointed at 

 apex, but not distinctly constricted. Prothorax trapezoidal, wider tlian long, 

 sides nearly straight, hind angles rather strongly divergent. Prosternal process 

 narrow, nearly as in mandibularis. Length 1.3 mm. 



Santa Fe (Fenyes). 



This species agrees with bicolor in its only moderately prominent 

 mandibles, with mandibularis in its narrow prosternal process, and 

 with estriatMs in its narrow feebly serrate antennae. The prothorax 

 is more strongly narrowed from the base and more sparsely finely 

 punctured than in any of these species, and the disparity in color 

 between the upper and lower surfaces is less marked than usual. 



BUPRESTIDJ^. 



Chrysobothris convexa n. sp. — Moderately robust, more strongly con- 

 vex than usual, both above and beneath ; bronzed, moderately shining. An- 

 tennse not narrowed externally, bronzed at base, outer joints piceous, third joint 

 as long as the next two. Front convex, pubescent, with a single well-defined 

 chevron. Clypeus with a very narrow acute cuspiform emargination, margin 

 each side broadly squarely truncate. Eyes more widely separated on the vertex 

 than their own width as seen from above. Prothorax three-fifths wider than 

 long, widest near the front, sides nearly straight and convergent posteriorly, 

 more rapidly convergent to apex, which is a little narrower than the base; sur- 

 face moderately closely somewhat irregularly punctate, a transverse series of 

 four small, feebly elevated, smooth callosities before the middle ; median line not 

 at all impressed, smooth posteriorly, separating two rather broad but distinct 

 basal impressions, which are limited laterally by a short smooth longitudinal 

 elevation. Elytra slightly wider than the prothorax, not quite twice as long as 

 wide, sides parallel in basal three-fifths, apices rounded and serrulate; each with 

 three narrow smooth discal costse, the first nearly parallel with the suture,
