REVISION OF NEARCTIC TERMITES. 141 



mainland, at Miami Beach, 3 miles across Biscayne Bay from Miami, 

 and Cocoanut Grove (Brickell Hammock); on Adam Key, a coral 

 reef in Dade Comity, about 27 miles south of Miami; and Paradise 

 Key (Royal Palm Hammock), in the Lower Everglades, approxi- 

 mately 48 miles southwest of Miami, and west of West Lake, Lower 

 Everglades, in dead saw-cabbage palmetto trees (Paurotis) in ham- 

 mocks. 



N. castaneus burrows in the decayed wood of dead trees, logs, 

 stumps, and branches. It is a large species and the burrows and 

 chambers excavated in the wood are imusually large. (PL 23.) 



SWARMING. 



On May 14, 1916, winged, pigmented adults of this termite were 

 found in a large colony at Paradise Key, Florida. It probably 

 swarms the last of May or first of Jime. Winged adults attaining 

 mature pigmentation were found on February 25, 1919, west of 

 West Lake, in the Lower Everglades. 



E. A. Schwarz collected winged adults at Cayamas, Cuba, "27/5." 

 P. Cardin collected adults flying at dusk, at light, May 24, 1918, at 

 Santiago de las Vegas, Cuba. 



In the soldier caste the antenna is simple; that is, the third joint is 

 not enlarged, as in most species of Kalotermes; also the femora are 

 not swollen, as in species of Kalotermes (fig. 20). 



In habits this species of Neotermes is not different from species of 

 Kalotermes. According to Hagen (1858) a specimen in the Museum 

 at Vienna bears the label, " f requentissime in domibus habitat?" 

 Biologically Neotermes is closely related to Termoysis, much more so 

 than to Kalotermes. There is an "ergatoid" nymph similar to that 

 in Termopsis; there are similar impressed pellets of excrement 

 which resemble those of Termopsis. 



The Rev. F. L. Odenbach, of Cleveland, Ohio, has kept alive a 



colony of this species for 17 years. The interesting notes he has 



taken on this colony are quoted in a previous paper (Thompson and 



Snyder, 1919).

Genus CRYPTOTERMES Banks. 



All the species of Cryptotermes Banks are interesting because of the 

 peculiar shaped head of the soldier. The front of the head has a 

 "caved in" or truncate appearance. Only three species of Crypto- 

 termes have been found in the United States: C. cavifrons Banks of
