Casey — Observations on the Staphylinidae. 379 



sinuate to the base; punctures sparse, fine and rather feeble ; elytra 

 longer than wide, as long as the prothorax and slightly wider, the 

 punctures rather fine but close-set throughout, except along the upper 

 part of the deflexed flanks, where there is the usual polished impunc- 

 tate line ; abdomen nearly as wide as the elytra, inconspicuously punc- 

 tulate as usual. Length 5.0 mm.; width 0.73 mm. Wellington. 



langnidns n. sp. 



4 — Form stout, parallel, shining, dark rufo-piceous throughout, the legs 

 and antennae pale; head in the male large, gradually dilated toward 

 base, with the eyes small, in the female a little narrower, parallel, with 

 the eyes larger, the basal angles unusually broadly rounded in both 

 sexes, the punctures very fine, remotely scattered toward the sides; 

 third antennal joint notably longer than the second; prothorax large 

 In the male, much smaller and shorter in the female, scarcely narrower 

 than the head in the former, distinctly so in the latter, a fourth to nearly 

 two-fifths longer than wide, the sides strongly converglDg and the apical 

 angles rather broadly rounded, the punctures rather fine and sparse but 

 distinct; elytra scarcely as long as wide, much shorter and slightly 

 wider than the prothorax, the punctures rather fine but strong and close- 

 set throughout; abdomen broader than usual, about equal in width to 

 the elytra, finely, sparsely punctulate. Length 5.9 mm. ; width 0.9 mm. 

 Cape Town capensis n. sp. 



Form moderately stout, parallel, shining, smaller In size, rufo-piceous 

 throughout, the legs and antennae paler; head behind the antennae 

 rather longer than wide, parallel, the basal angles moderately rounded; 

 punctures fine and somewhat close- set laterally, wanting almost through- 

 out the width anteriorly, the antennae nearly as in the preceding species ; 

 prothorax two-fifths longer than wide, equal in width to the head, the 

 apex sublruncate, the apical angles very distinct and only narrowly 

 rounded, tne sides rather strongly conrerging; base subcircularly 

 rounded, the punctures fine and sparse; elytra and abdomen nearly as 

 in capensis. Length 5.6 mm.; width 0.8 mm. Cape Town. 



diligens n. sp. 



The more sharply angulate basal angles of the head and 

 apical angles of the prothorax and general form of the head 

 serve to distinguish diligens from capensis, the type of the 

 former being apparently a male. 



Enlissns Mann. 



The genus Eulissus appears to be the only one devoid of 

 dorsal pronotal series of punctures known thus far to the 

 palaearctic fauna. These structural types are numerous in 

 the warmer parts of North and South America and Eulissus 

 is approached most closely perhaps by the genus Saurohyp- 

 nu8, of Sharp. The pronotum is not wholly sculptureless in
