MONOGRAPH OF WEST INDIAN STAPHYLINTDAE 183 



Records. — The following is the only record known to me : 

 Cuba: Imias (Darlington, in M.C.Z.)- 



Specimens examined. — I have seen only the holotype. 



Remarks. — This specimen differs from cubensis in numerous small 

 details and especially in the shape of the pronotum. 



I have received no record of its habits.

DescHption. — Piceous. Head about four-fifths as wide as prono- 

 tum; eyes slightly prominent; clypeus truncate, margin finely crenu- 

 late; labrum scarcely emarginate, alutaceous; antennae slender; 

 faintly or not alutaceous except basally, distinctly punctulate ; with a 

 few larger punctures at sides. Pronotum one-tenth wider than long, 

 slightly narrowed behind, base nine-tenths as wide as apex; sides 

 feebly arcuate; apical angles denticulate; lateral margin only slightly 

 broader basally, with conspicuous smooth midline; not alutaceous 

 but strongly punctulate. Elytra as wide as pronotum and as long 

 as wide; sides nearly parallel; with a few large setigerous punc- 

 tures; coriaceous. Ahdomen not distinctly alutaceous, finely not 

 densely punctate. Anterior face of front tibia with setigerous punc- 

 tures scattered. Length, 71/2 mm. (From Darlington.) 



Type locality. — Central Cuba, Central Soledad, near Cienfuegos, 

 Santa Clara Province. 



Types. — Holotype in the Museum of Comparative Zoology (No. 

 21238). 



Records. — The following is the only record known to me: 



Cuba: Central Soledad (Darlington, 1937). 



Specimens examined. — I have seen no examples of this species. 



Reinarks. — Though separated in the key from manni^ this species 

 is very similar to it. In fact I think it very unlikely that it can be 

 retained as distinct. The considerable difference in size appears to 

 me to be the only positive character distinguishing them. Since both 

 are represented by unique types, it will be necessary to obtain addi- 

 tional material before a solution can be found, unless a study of the 

 genitalia of this genus reveals usable specific characters. (The 

 type of manni is a female.)
