450 STAPHYLINIDAE. 



legs reddish-testaceous. Length (in well extended examples) 

 5 mm. A rather broad subdepressed species with facies of 

 Tachinus. Head black, m front rufescent, the vertex with a 

 very fine smooth shining line in the middle, between the bases 

 of the antennae with a fine transverse shining line, joined by 

 the preceding, the rest of the surface finely, sparingly 

 punctured, glabrous, very distinctly coriaceous; eyes not 

 prominent, semi-circular. Antenna? with the 2nd and 3rd 

 joints of equal length the 4th a little longer than broad 

 narrowed at the base, the 5th much stouter, obconical, 6th 

 scarcely longer than broad. 7th to 10th transverse, gTadually 

 increasing in breadth, 11th oval, oblong, nearly as long as the 

 two preceding together. Thorax strongly transverse, widest 

 a little in front of the obtusely rounded posterior angles, the 

 sides margined, evenly rounded and narrowed ant^iorly ; 

 base not bordered ; puncturation and ground sculpture as on 

 the head, glabrous. Elytra a little wider and longer than the 

 thorax, transverse, very little narrower at the base, the sides 

 very slighth' rounded, broadly superficially impressed from the 

 shoulder to the posterior third, postero-external angles broadly 

 rounded, puncturation and ground sculpture as on the fore 

 parts. Abdomen narrowed from base to apex, more shining 

 than the fore parts, very finely and sparingly punctured, very 

 finely and sparingly pubescent, ground sculpture very fine, 

 transversely strigose. much less distinct than the fore parts. 



cf . 8th dorsal segment in the middle on either side with 

 a short, broad pointed lobe separated from each other by a 

 shallow arched emargination. and from the less advanced 

 postero-external angles by a broad shallow emargination ; 5th 

 ventral segment broadly triangularly impressed for the posterior 

 two-thirds in the middle line : fith broadly triansnlarly excised 

 in the middle, on either side of the excision with a setiferous 

 tubercle, between this and less advanced postero-external 

 angle, broadly shallowly emarginate. the emargination with 

 a small tooth, the postero-external angle with a long seta. 



9 ■ 8th dorsal segment posteriorly with four long processes. 

 the inner yjair narrower and sliffhtlv more advanced than the 

 outer ; 6th ventral segment with six long processes, the two 

 inner broader, more advanced and separated from each other 

 'n- a deep oval excision, the apex of each with three spines. 

 the lateral spines subequal and with a seta at the apex of each. 



Mt. Duht, 3500 feet. 4 specimens.
