STAPHYLINIDyE. 17 



wider than the head, widest just behind the middle, where it is slightly 

 wider than the elytra, the sides rounded, more converging anteriorly, 

 the base strongly, evenly arcuate, becoming transverse near the angles, 

 which are slightly more than right but not at all blunt; surface evenly 

 and moderately convex, unimpressed; elytra parallel, only moderately 

 transverse, the suture just visibly longer than the prothorax; abdomen 

 slender, much narrower than the elytra, parallel, narrowing a little 

 and very pale apically, the fifth tergite much longer than the fourth, 

 the sixth (c?) truncate medially at apex, the truncature with about six 

 slender aciculate close-set serrules and separated at each side from a 

 slender porrect spicule by a moderate sinus. Length 1.85 mm.; width 

 0.48 mm. Rhode Island (Boston Neck). 



Related to angustiventris but separable at once by its very short 

 vestiture and much stouter, more incrassate antennae; the type 

 was inadvertently included under that species in my original 

 description. Angustiventris, described originally from Cedar Rapids, 

 Iowa, has since been collected by Wickham at Iowa City. 



Ischnoglossa tenuicauda n. sp. Rather stout and convex anteriorly, 

 the abdomen slender, slightly shining, dark red-brown, the abdomen with 

 a blackish cloud at the fourth tergite, the head also blackish; punctures 

 small but rather close-set and asperate, dense on the elytra, the pubescence 

 short, rather abundant and subdecumbent; head small, convex, trans- 

 verse, the eyes convex and prominent, at about half their length from the 

 base, the tempora less prominent; antennae pale, moderately short, 

 strongly incrassate, the first three joints subequal in length, the fourth 

 about as long as wide, the outer joints more than one-half wider than 

 long, the last longer than the two preceding; prothorax formed nearly 

 as in abscissa, but widest more nearly at the middle, less dilated and not 

 wider than the elytra, the latter relatively larger, parallel, the suture 

 distinctly longer than the prothorax; abdomen much narrower than the 

 elytra, slender, parallel, with thick margins, feebly narrowing apically, 

 the sexual characters nearly as in abscissa. Length 2.3 mm.; width 0.56 

 mm. Florida. 



Differs from abscissa, to which as well as angustiventris it is 

 allied, by its relatively larger elytra, smaller head and more elon- 

 gate fourth antennal joint; from the latter it differs, in common 

 with abscissa, in its much shorter vestiture. The type was erro- 

 neously included with the types of angustiventris in my description 

 of that species. 



Ischnoglossa intenta n. sp. Moderately stout and convex, the ab- 

 domen very slender, red-brown, the legs and antennae still paler, the 

 tergites all blackish at their bases; surface feebly shining, finely, closely, 

 asperately punctate, the vestiture pale, very short, rather close and fine, 

 longer though very fine on the abdomen; head small, convex, transversely
