REVISION OF THE TENEBRIONID.fi OF AMERICA, 



R, flabellicornis, Sturm. (Xyletinus) Oat. 1820, p. 50, pi. 1, &g. 7. 



I have before me ten specimens of this insect, and find them all agreeing with the 

 characters of the genus as defined by Dr. Leconte, and showing no differences among them- 

 selves in the formation of their antenna". The species is similar in sculpture to the 

 Kledona before- described. The antennae and legs are pah; reddish brown. 



Length .10 inch. 



Middle and Western States and Canada West (Pettit). 



May not this genus be allied to the Eutomides, lately referred to this family'? 



TRIBE XX [X APOCRYPHINI. 



Body slender, apterous ; head not constricted behind ; labrum prominent, clypeal mem- 

 brane distinctly visible; eyes small, emarginate, coarsely granulated; mention small; last 

 joint of maxillary palpi strongly securiform; antenna 1 eleven-jointed, slender, scarcely 

 thicker externally; prothorax globose, marginal ridge rounded or wanting; trunk pedun- 

 culated; elytra, embracing widely the flanks of abdomen; epipleurse narrow; middle coxa) 

 without trochantin ; hind coxa' small, widely separated ; legs long, femora clavate ; tibia' 

 slender, spurs small ; tarsi pubescent with long hairs ; hind margins of third and fourth 

 ventral segments coriaceous. 



The last character alone serves to remove this tribe from the association in which it 

 was placed by Dr. Leconte, to the place assigned it by Lacordaire, preferring, however, 

 to retain it as a distinct tribe. 



APOCRYPHA, Esch. 

 Apocrypha, Esch., Zool. Atl. IV, p. 18. 



Our species, three in number, all small, are found in California, under chips, etc., 

 in very dry places ; they are very agile and difficult to capture. 



A. anthicoides, Esch., loc. cit., pi. 18, fig. 7. 



Thorax globoso-oval, broader than long; broader in front of middle, sides strongly 

 rounded and gradually narrower toward apex. Surface rather coarsely but sparsely punc- 

 tured, and very sparsely clothed with yellowish hairs. Color brownish testaceous, elytra, 

 blackish, base broadly brownish testaceous. Beneath colored as above, legs paler. 



Length .11 inch. 



San Francisco and Tejon, Cal. 



A. dyschirioides, Lee, Ami. Lye. V, 187. 



Smaller than the preceding. Head and elytra, dark brown or black, thorax rufous, 

 shining. Thorax longer than broad, sides nearly straight in front, gradually widening 

 beyond the middle, then rapidly narrowing. Under surface blackish, feet rufous. 



Length .08-10 inch. 



Found with the preceding.
