STAPHYLINID.E. 75 



than the prothorax, wider than long, not much swollen and with rounded 

 sides hasally, the eyes prominent, at a little more than their own length 

 from the base and slightly less prominent than the sides behind them; 

 antennae as in occipitalis but not quite so stout, the outer joints less 

 transverse, the last joint longer than the two preceding, gradually very 

 acutely pointed; prothorax two-fifths wider than long, evidently wider 

 than the head and correspondingly narrower than the elytra, feebly ob- 

 trapezoidal, with but slightly arcuate sides, the surface feebly impressed 

 longitudinally near each side, having, parallel with the basal margin, 

 a transverse subimpressed line slightly more advanced at the middle, 

 the median line very faintly impressed; elytra moderately transverse, 

 much longer, as well as wider, than the prothorax, nearly flat, the straight 

 sides feebly diverging from base to apex; abdomen subparallel, not as 

 wide as the elytra. Length 2.7 mm.; width 0.58 mm. Arizona (Walnut), 

 Wickham. 



Distinguishable from occipitalis by the denser sculpture and duller 

 lustre, relatively smaller head, which is less enlarged at base or less 

 triangular, with smaller eyes which are at a greater distance from 

 the base, less stout and darker antennae, less transverse prothorax, 

 longer, relatively narrower and less parallel elytra and by the incised 

 transverse basal line of the pronotum, which is wholly wanting in 

 occipitalis and replaced by a transversely oval ante-scutellar im- 

 pression, not observable in relrusa. 



Apalonia Csy. 



The very minute species of this genus resemble outwardly, to 

 some extent, very much reduced forms of the fauveli type of M yr- 

 medonia, and there is similarly no trace of infra-lateral cephalic 

 carinse; the following is an additional species: 



Apalonia divisa n. sp. Rather slender, subcuneiform, convex, highly 

 polished, impunctate, excepting a few fine setigerous punctures, the 

 abdomen with four longitudinal series of punctures bearing longer 

 black setae, situated at the apices of the tergites; color very pale flavo- 

 testaceous, the head and a transverse discal elytral band, interrupted 

 at the suture, darker, piceous, the abdomen, excepting the first two seg- 

 ments, deep black; head moderate, wider than long, parallel and nearly 

 straight at the sides, the eyes small, prominent, at much more than their 

 own length from the base; antennae rather short, very slender and pale 

 flavate, becoming rapidly thick and blackish apically, having sparse 

 black setae as in seticornis and also Myrmedonia fan-veil, the third joint 

 not longer than the second and much thinner, four to six longer than 

 wide, seven as long, and the ninth nearly as long, as wide, the tenth 

 moderately transverse, the last symmetrically pointed apically and rather 

 longer than the two preceding; prothorax obtrapezoidal, equal in width
