Jamaica. This may be a misidentification. Gibson (Ent. News, 
XXVIII, 444, 1917) is certainly in error in stating that the 
beak in serratus does not extend beyond the metasternum and 
in reporting the species as occurring over practically the entire 
United States. Van Duzee in his Catalogue records it from 
Florida and Texas. 
Harmostes affinis Dallas 
1852. Harmostes affinis Dallas, List Hem. II, 522. 
Seven specimens from Antigua. These answer in every re- 
spect to Dallas’ short description of the species, the habitat of 
which was unknown. Mr. Van Duzee in recording the species 
from Florida (Bull. Buffalo Soc. Nat. Sci., IX, 161, 1909) gives 
a good account of the differences between this species and 
serratus. It is known also from Jamaica. 
Corizus hyalinus Fabricius 
1794. Corizus hyalinus Fabricius, Ent. Syst. IV, 168. 
Three specimens from Antigua. This species, almost cos- 
mopolitan in its range, has been recorded from Cuba, Jamaica, 
and Grenada. I have determined specimens in the collection of 
the American Museum of Natural History from Cuba, San 
Domingo, Antigua, and Porto Rico. The West Indian speci- 
mens differ in no respect from those in the United States. Van 
Duzee in 1909 reported it from the Bermuda Islands. 
Corizus side Fabricius 
1794. Corizus side Fabricius, Ent. Syst. IV, 169. 
1859. Corizus pictipes Stal, Freg. Eug. Resa, Ins., 239. 
1842. Corizus vincentii Westwood, in Hope Cat. II, 26. 
One hundred and four specimens from Antigua and three 
from Barbados. A widely distributed and common species 
throughout most of the neotropical realm, spreading into the 
southern United States. Reported from Grenada, St. Vincent, 
Jamaica, Cuba, and Isle of Pines. Specimens from San Do- 
mingo, Guadeloupe, Porto Rico, Cuba, and Jamaica are to be 
found in the American Museum of Natural History collections. 
Mr. Morrison has taken it also in St. Croix. This species is
