MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 173 



long, suddenly narrowed basally, base about five-sixths as wide as 

 apex; sides evenly arcuate in apical two-thirds, then emarginate to 

 base; with elevated impunctate median stripe, not set off by definite 

 series of punctures; with coarse setigerous punctures generally not 

 separated by their diameter; obsoletely alutaceous. Elytra a little 

 wider than pronotum, as wide as long, not much enlarged ; with coarse 

 but very small setigerous punctures, rather dense but not at all serial, 

 somewhat obscured by the dense but feeble alutaceous ground sculp- 

 ture. Abdomen with only traces of alutaceous ground sculpture; 

 with moderately large but shallow and indistinct setigerous punc- 

 tures. Anterior face of front tibia with a rather indefinite series of 

 setigerous punctures. Length, 2 to 21^ mm. 



Tyi)e locality. — "New Caledonia, Bourail. — Sumatra." Of fawveli., 

 Haiti. 



Types. — Presumably in the collection of Blanche Rancin, Caen, 

 France. Of faii/veli^ in the collection of Dr. Cameron. 



Records. — The following are the records known to me : 



Cuba: (C. Wright, in M.C.Z and U.S.N.M.). 



Jamaica: Milk River (Blackwelder station 415), Moueague (Blackwelder station 



375), Santa Cruz (Blackwelder station 421), Spanish Town (Blackwelder 



station 377), Troy (Blackwelder station 409). 

 Hispanlola: Haiti (Cameron, 1913, as faiiveli; Leng and Mutchler, 1914; Not- 



man, 1925); Dominican Republic, Sanchez (Darlington, in M.C.Z.) . 

 Puerto Rico: Juana Diaz (Oakley, in U.S.N.M.), Lajas (Dozier, in U.S.N.M.). 

 Guadeloupe: (Fauvel, 1903; Bernhauer, 1910). 



Central America: Mexico (Bernhauer, 1910; Notman, 1825; U.S.N.M.). 

 Africa: Madagascab (Fauvel, 1903; Bernhauer, 1910; Cameron, 1930), Seychelles 



Islands (Bernhauer and Schubert, 1911). 

 Orient: Burma (Fauvel, 1903), Ceyi.on (Fauvel, 1903), Singapoee (Cameron, 



1921), India (Bernhauer, 1910; Cameron, 1930), Malay (Cameron, 1930), 



SuNDA Islands (Bernhauer, 1910), New Caledonia (Fauvel, 1889; Cameron, 



1930), Sumatra (Fauvel, 1SS9 ; Cameron, 1928, 1930). 



/Specimens examined. — I have seen 1 example from the West Indies 

 in Dr. Cameron's collection, 3 from the Museum of Comparative 

 Zoology, 7 in the United States National Museum, and 30 collected 

 by Chapin and Blackwelder in February 1937. I have seen also 

 specimens from India, Singapore, and Mexico. 



Remarks. — This species could be easily confused with Osorius^ but 

 it is readily distinguished by the posterior emargination of the sides 

 of the pronotum. This is the only species of the genus known to 

 occur in the Western Hemisphere. 



My specimens were all caught flying at dusk; five of the Puerto 

 Rican specimens were intercepted by the Plant Quarantine service 

 at New York "in soil from Puerto Rico."
