[(Schwarz's San Diego, Texas, specimens were Constrictotermes cinereus Buckley 

 and Amitermes (?) perplexus Banks, winged adults of the latter being collected on May 31 

 and thought to be " Termes fumosus Hag. ")•] 



I found this species [(Constrictotermes cinereus Buckley)] throughout spring and fall 

 in smaller or larger colonies, usually witliin tolerably dry cow's dung, in which it 

 constructs long and winding galleries. Other colonies were seen under fence boards 

 lying on the ground, and one under a large Poh/porvs lying on the ground. The 

 species is much more active than any other termite known to me, and closely resembles 

 in its movements one of the wingless Psocids. The colonies are composed of workers 

 and nasuti, the former being much more numerous than the latter. In no instance 

 has a single larva or sexed individual ever been seen in siich situation. It must be 

 inferred, therefore, that the true nest is deep in the ground. 



On May 31 a flight of termites [Amitermes (?) perplexus Banks] "took place on the 

 public square of the town of San Diego during a rainstorm. I failed to find the exact 

 spot from which the swarms issued, but the specimens proved to belong to Eutermes. 

 Since no other species of this genus was ever seen by me in southwestern Texas, I 

 infer that these winged specimens belong to Eutermes nigriceps. They agree well 

 with Hagen's description of Termes (Eutermes) fumosus from Vera Cruz, Mexico 

 (Linn. Ent. 14, p. 123), of which Dr. Hagen himself thinks that it may be the winged 

 form of Haldeman's species. "

LEUCOTEKMES TENUIS Hagen. 



For taxonomy see p. 76. 



This species, whose habitat is Santo Domingo (Port aux Princes) 

 and Brazil ( according to Hagen) , has also been found in the Bahamas 

 (Fish Hawk Key, Andros Island) by Desneux. He collected winged 

 adults on May 19, 1904. According to Sharp (1901) this termite was 

 introduced to the Island of St. Helena and was so destructive that 

 Jamestown, the capital, was practically destroyed and new buildings 



had to be erected. 



swarming. 



This termite swarms during the first part of May in Cuba and the 

 Bahamas. Winged adults were collected on Fish Hawk Key, Andros 

 Island, Bahamas, May 19. It occurs in various places in Cuba and 

 southward to South America. E. A. Schwarz collected winged 

 adults of this termite at Cayamas, Cuba, "6/5, 18/5, and 11/6." 

 Specimens of workers and soldiers of L. tenuis from Coxipo, Cuyaba, 

 Brazil, are in the collection of the United States National Museum. 

 This species occurs in Panama, Obispo (Banks, 1918). 



According to Silvestri (1903) Leucotermes tenuis has two types of 

 soldiers — "miles major" and "miles parvus." Mr. Banks and the
