Goleopterological Notices, VI. 647 



truncate at base, the angles rounded; tempora parallel; eyes small and feebly 

 convex; antennfe nearly one-half as long as the body, gradually and strongly 

 incrassate, the eleventh joint much shorter than the two preceding. Ptoihorax 

 cnly just visibly narrower than the head, a little longer than wide, deeply 

 constricted near basal third, the anterior lobe very large, wider than long and 

 widest near its anterior third, somewhat trapezoidal, the sides arcuate; basal 

 margin distinct; collar very short but deeply constricted. Elytra two-fifths 

 longer than wide, abruptly, obtusely rounded behind, inflated and distinctly 

 wider in the middle than at base; humeri distinct; disk transversely impressed 

 near the base; omoplates large and onh* moderately prominent. Abdomen 

 finely but sparsely pubescent. Legs moderately short and stout, pubescent. 

 Length 1.9 mm. ; width 0.7 mm. 



Texas (Austin). 



The single specimen is a female and represents a species allied 

 distinctly to munda^ but ditfering markedly in the form of the 

 prothorax and in the quadrate head. 



4. F. gilensis n. sp. — Narrow, convex, polished and sculptureless through- 

 out the upper surface, with some short and slender and long stiff bristling 

 setae; bod}- black, the metasternum, legs and prothorax more or less rufescent; 

 antennae pale testaceous; elytra with a narrow straight flavous fascia near the 

 base and another, similar, distinctly behind the middle. Head oval, rather 

 longer than wide, rounded at base, the angles very broadly rounded; eyes 

 small, just before the middle, convex and prominent; antennae rather less than 

 one-half as long as the body, gradually and moderatelj- incrassate, the last 

 joint as in munda. Prothorax scarcely visibly naiTower than the head, dis- 

 tinctly longer than wide, deeply constricted near basal third, the anterior lobe 

 wider than long, subelliptical and widest rather before the middle ; basal mar- 

 gin distinct. Elytra one-half longer than wide, barely twice as wide as the 

 prothorax, almost evenly, not abruptly rounded behind, quite distinctly in- 

 flated, and noticeably wider at or just behind the middle than at base; humeri 

 distinct, widely exposed and obliquely rounded at base; disk feebly impressed 

 near the base. Abdomen finely and rather densely pubescent. Legs distinctly 

 and more coarsely pubescent, moderately long, the femora qrrite stout and sub- 

 pedunculate. Length 2.0 mm. ; width 0.65 mm. 



Arizona (Tucson). 



The single male, from which this description is drawn, has the 

 copulatory spicule almost completely protruded ; it is of singular 

 form and very simple structure, three-fifths as long as the entire 

 abdomen, slender, nearly straight in profile and gradually acutelj"- 

 and extremel}' finel}' attenuate from base to apex, the sides 

 straight; the slender efterent duct beneath is much shorter, and 

 is onh' partiall}' and basally sheltered in the inferior excavation 

 -of the spicule, the latter scarcelj' serving as a protective sheath.
