mine the amount of time that has been required for the selection 
of short wings, but I imagine that the process has been rapid and 
in the span of a few thousand years. 
Creagrophorus jamaicensis Peck, 1972 
My Jamaican field work yielded no collections of this poorly 
known genus and species. However, Dr. Newton has found another 
four specimens in the collections of the Museum of Comparative 
Zoology, from Port Antonio, Jamaica, collected by A.E. Wight, 
“12/14.” The male protarsal segment number was previously not 
known for this species. Examination shows that the one male in 
the new material has three protarsal segments. Thus, the tarsal 
formula for both sexes of the species is 3-3-3. Since Matthews 
(1888) reported his species to have a formula of 4-4-3, they should 
be reexamined to confirm this and allow a more secure character- 
ization for the genus. The unusual shape of the first abdominal 
sternite that Matthews mentioned is a longitudinal carina crossing 
the face of the segment, so that it superficially looks as if it were 
composed of two segments, of which the first is triangular and 
separated by the coxae. The characters of the longitudinal carina 
across the first abdominal segment and the 3-3-3 tarsal formulae 
of both sexes are shared with Aglyptinus and the Scotocryptini, 
eyeless inquilines in Meliponine bee nests. These characters unite 
all these beetles more than had been previously thought. The com- 
pact antennal club of Creagrophorus separates it from Aglyptinus 
and the Scotocryptini, with their longer and less compact clubs. 
Apheloplastus Brown 
Diagnosis (drawn from Brown, 1937, 1963). Shape rounded, 
strongly convex. Antennae with 10 segments, club composed only 
of last four enlarged segments, with no smaller segment between 
the seventh and eighth. Antennal grooves beneath head. Pro- 
sternum finely carinate before the coxae. Mesosternum carinate, 
vertical between coxae. Middle and posterior legs with tibiae very 
broad, and tarsi compressed. Male and female with tarsal formu- 
lae of 5-5-4. Six visible abdominal sternites. 
The aedeagus is unusually small in relation to adult body size, 
ranging from 0.2 to 0.3 mm in different species.
