MONOGRAPH OF WEST INDIAX STAPHYLINIDAE 103 



stices. Male, seventh steriiite Aaguely emurgiiiate, eighth somewhat 

 depressed and feebly emarginatc; ninth longitudinally depressed. 

 Female^ unknown. Length, 3 mm. 



Type locality. — Jamaica, main range of Blue Mountains, elevation 

 5,000 to 7,388 feet. 



Types. — Holotype, Museum of Comparative Zoology, collected by 

 Dr. P. J. Darlington on August 17-19, 1934. 



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



Jamaica: Blue Mountains (Darlington, in M.C.Z.). 



Specimens examined. — I have seen only the holotype. 

 Remarhs. — This species is very distinct from all others in the 

 West Indies. It can be recognized at once by its strigose. surface. 

 I have received no record of its habits. 



IX. Genus PAROSUS Sharp 



Purofius SHAiiP, 1887, p. 701. 



Genotype. — P. hUa.ris Sharp (monobasic). 



Diagnosis. — Body depressed, punctate; antennae inserted at sides 

 of head close to eyes; labrum profoundly emarginate at middle 

 and dentate at sides; mandibles porrect, curved; maxillary palpi 

 subulate, third segment much enlarged; gular sutures united at gular 

 pits in center of ventral surface, continued as single suture; pro- 

 sternum short, anterior coxal cavities confluent, widely open behind; 

 coxae not very prominent though rather transverse; jniddle coxae 

 contiguous; posterior coxae contiguous, not expanded laterally under 

 the femora; abdomen strongly margined; sternites of the first and 

 second segments not present; tibiae unarmed; tarsi 3-segmented. 



Rrviaik.s. — The genotype from Panama and the two species frcmi 

 the West Indies are the only members of this genus known. The 

 above diagnosis has been taken from Sharp's re'narks and from a 

 series of P. hiiaris in the United States National Museum.
