Goleoptei'ological Notices, VI. 64*1 



trunc<ate at base, the angles rounded ; tempora parallel ; eyes small and feebly 

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

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

 only 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 ))ase; humeri distinct; disk transversely impressed 

 near the base; omoplates large and only moderately prominent. Aljdomen 

 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 diftering markedly in the form of the 

 prothorax and in the quadrate head. 



4. F. gileiisis n. sp. — Nari'ow, convex, polished and sculptureless through- 

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

 setae; body black, the metasternum, legs and prothorax more or less rufesceut; 

 anteunie pale testaceoiis; elytra Avith a narrow straight flavous fascia near the 

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

 longer than wide, lounded 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 bodj^, gi'adually and moderately incrassate, the last 

 joint as in miimhi. Profliorux scarcely visibly narrower than the head, dis- 

 tiuctl}' longer than wide, deeply constricted near basal third, the anterior lobe 

 wider than long, subelliptieal 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 quite stout and sub- 

 pedunculate. Length 3.0 mm. ; width 0.65 mm. 



Arizona (Tu9son). 



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

 copulatory spicule almost completel}^ 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 acutel}' 

 and extremely finely attenuate from Ijase to apex, the sides 

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

 is only partially and basally sheltered in the inferior excavation 

 -of the spicule, the latter scarcel^^ serving as a protective sheath.
