I* texana n. sp. — Oblong, the sides nearly straight and parallel in middle 

 two-thirds, pale ochreous-testaceous throughout, rather shining ; pubescence 

 fine and dense. Head moderate in size, nearly one-half as wide as the pro- 

 thorax, feebly convex, impressed at the base of the epistoma, finely and not 

 very densely punctate ; eyes large ; antennae very long and slender, filiform, 

 two-thirds as long as the body, third and fourth joints slender, equal. Pro- 

 thorax a little less than twice as wide as long, strongly narrowed from base to 

 apex ; sides strongly, almost evenly rounded, almost parallel in basal third ; 

 apex truncate, three-fifths as wide as the base, the latter transverse, the 

 sinuation, on each side of the rather narrow median lobe, feeble but distinct ; 

 basal angles right, narrowly rounded ; disk strongly convex, finely, densely 

 punctate, the punctures slightly separated ; basal foveae almost obsolete. 

 Elytra about three and one-half times as long as the prothorax, and, at the 

 middle, not appreciably wider, rather abruptly, strongly rounded behind ; 

 disk comparatively coarsely, very densely punctate, with series of nearly 

 similar close-set punctures, the series feebly impressed, especially strongly 

 so toward apex throughout the width. Abdomen finely, rather sparsely punc- 

 tate, the metasternum extremely sparsely, rather coarsely so, the propleuree 

 polished, finely, sparsely punctate throughout. Legs slender, the basal joint 

 of the hind tarsi distinctly shorter than the remainder. 



Male. — Eyes separated by their own width ; fifth ventral segment nearly as 

 in valida, but rather more rounded behind. 



Length 7.7 mm. , width 3.1 mm. 



Texas. 



This species is allied to valida, but easily distinguishable by its 

 more oblong parallel form, longer prothorax, larger head, smaller 

 and more distant eyes, more distinctly impressed elytral series, and 

 more sparsely punctate abdomen. 



The maxillary palpi are nearly as in valida, the last joint about 

 twice as long, but scarcely twice as wide as the penultimate, the 

 outer side about one-fourth longer than the apex, the inner side a 

 little more than one-half as long as the outer. 



TEDIXUS n. gen. 



Mandibles distinctly notched at apex, the lobes subequal. Antenna? slen- 

 der, filiform, the third joint shorter than the fourth, less conspicuously so in 

 the female. Maxillary palpi with the fourth joint as in Isomira, rather slen- 

 der, the angle at the base less than right, the inner side much shorter than 

 the apex, the latter longer and more oblique in the male than in the female. 

 Labial palpi with the third joint one-half longer than wide, the apex truncate, 

 the truncation just visibly oblique. Anterior coxae separated by a distinct 

 longitudinally convex prosternal process, which attains the level of the coxal 

 apices, very declivous behind. Tarsi not as long as the tibiae, the basal joint 

 of the posterior elongate, the anterior distinctly dilated in the male ; ungues
