A single worker from Indefatigable Island (F. X. Wil- 
liams), unmistakably belongs to this species, though it is 
somewhat damaged. The hairs on the body, however, are 
more abundant, more flexuous and paler than in my speci- 
mens from Argentina, Brazil and British Guiana, but in this 
respect the Galapagos specimen agrees with a series taken 
by Silvestri at Talca, Chili. S. seevissima, as the foregoing 
localities show, is very widely distributed in tropical America. 
It was originally described from Brazil. 
7. Solenopsis geminata (Fabricius). 
Emery records this species as having been taken by Baur 
on Chatham Island. Perhaps the specimens belong to the 
following variety. I have omitted the long and tangled 
synonymy of S. geminata, much of which can be found in 
Dalla Torre’s Catalogus Hymenopterorum 7, 1893, p. 76. 
8. Solenopsis geminata galapageia, new variety. 
Several workers and females taken by Dr. Williams on 
Charles Island “under stones near top of crater’ average 
smaller than the corresponding phases of the typical geminata. 
The females are only 6—6.5 mm., the largest workers only 
44.5 mm., whereas the females of the typical geminata 
measure 7—8 mm., the largest workers 6—6.5 mm. In color 
the Galapagos specimens are much like the typical Central
