the adjacent island of Cuba (and Hispaniola in antilleorum and 
blackwelderi). 
Two of the other 16 species listed are based on records that can- 
not be verified: Acanthinus ebeninus on an old specimen with a 
“Cuba” label, and Amblyderus sp. on some specimens from Puerto 
Rico that cannot now be located. Ten are shared with continental 
areas of the New World: Acanthinus angusticollis, concinnus, quin- 
quemaculatus and scitulus, Anthicus pallidus, Sapintus similis and 
teapensis, Thicanus texanus, and Vacusus holoxanthus and vicinus. 
These may have reached the Greater Antilles without human help, 
but Vacusus holoxanthus is found mainly from Chile to Bolivia, and 
Acanthinus scitulus seems not to have been present in the lowland 
localities that were extensively collected in the 1930’s, so is probably 
of recent introduction. Finally, 4 species of Anthicus are of Old 
World origin: floralis and formicarius, which are almost cosmopoli- 
tan; tobias, which is expanding its range in several parts of the 
world; and crinitus. 
Two large genera, the world-wide Tomoderus and the New World 
Ischyropalpus, are conspicuous by their absence. The latter genus, 
at least, should have been collected if it was present; mainland spe- 
cies are often abundant on blossoms. That the fauna has not been 
completely sampled is indicated by the addition of a species of 
Mecynotarsus from Hispaniola through the recent collecting of J. 
and S. Klapperich. 
Acknowledgements 
A critical part of the material reported here was collected by 
Philip J. Darlington, Jr. in the 1930’s. I wish to thank Dr. Darling- 
ton and subsequent curators of the M. C. Z. for permission to retain 
these specimens until they could be studied in comparison with 
continental faunas. The second large lot came from the collecting of 
Richard E. Blackwelder and Edward A. Chapin, and was made 
available by the U. S. National Museum; it was collected in the same 
period. The largest recently collected lot originated in the collecting 
of J. and S. Klapperich in the Dominican Republic, and was made 
available by Dr. M. Branucci of the Naturhistorisches Museum in 
Basel.
