STAPHYLINIDS OF CAYMAN ISLANDS—-BLACKWELDER 119 
Not taken since the original discovery by Dr. M. Cameron. I have 
examined the type briefly but was unable to identify any of my speci- 
mens with it. (The statement in my monograph that no examples had 
been seen was an error due to an oversight.) 
5. CARPELIMUS sp. 
Little Cayman: South Town (1). 
One example that seems to differ from the four listed above is not 
identifiable at this time because of its condition. It appears to have 
an unusual type of sculpturing on the pronotum. 
6. BLEDIUS ESPOSUS Blackwelder 
Bledius esposus BLACKWELDER, U. S. Nat. Mus. Bull. 182, p. 114, 1943. 
Little Cayman: South Town (4). 
Taken in the light-traps in May and June 1938. This species was 
previously known only from the holotype from Antigua. One speci- 
men is deposited in the U. S. National Museum. 
7. BLEDIUS MANDIBULARIS Erichson 
Little Cayman: South Town (127). 
Taken in the light-traps in May and June 1938. This is the most 
unusual record in the entire collection, since it is a species previously 
unknown in the West Indies or in the Tropics. It is widespread but 
not common in the United States, ranging from Connecticut to Florida 
and west to Texas and Utah.

what picescent. Head very convex above but somewhat flattened be- 
tween the eyes, with irregular elevations along the midline, which is

straight, submentum strongly and deeply impressed at base, the pit 
imperfectly divided into two by a broad elevation of its floor, the pit
