Hawaiian Islands. ] 
Comparison of Hawaiian specimens with the large American 
series in the collections of the Philadelphia Academy proves con- 
clusively the synonymy indicated above. At the time varipenne 
was described, the literature on the genus was in great confusion, 
due largely to the very unsatisfactory treatment in Redtenbacher’s 
“Monographie der Conocephaliden.”’ 
The discussion of the species by Swezey, covering twelve 
pages, is extremely interesting and contains much valuable data. 
Rehn and Hebard have more recently shown that Niphidiwm 
meridionale, propinquum and brachypterum are synonyms of this 
species.* 
Previous to Swezey’s description of varipenne, the species had 
appeared generally in the Hawaiian literature as Xiphidium fus- 
cum, owing to Brunner’s original misidentification. 
Hawaii, 4000 feet, V, 8, 1919, (J. A. Kusche), 42 (1 brachyp- 
terous), [Hebard Coll.]. 
Mount Konahuanui, Oahu, VI, 6, 1919, (J. A. Kusche), 16, 
I 2 (brachypterous), [| Hebard Coll.]. 
The species appears to have been introduced into Hawaii about 
1890, and was reported as occurring “only around Honolulu,” in 
1899. It is now plentiful and very widely distributed in the Ter- 
ritory. 
In the Americas, saltator is the most widely distributed and 
abundant of the tropical species of the genus, occurring from Costa 
Rica and Montserratt in the West Indies southward to Paraguay.
