REVISION OF NEARCTIC TERMITES. 109 



Banlvs in Colorado by A. B, Champlain, and one young male collected 

 in a large colony in Colorado by B. T. Harvey. 



Only one male of this type has yet been found in colonies of species 

 of Reticulitermes. No nymphs with long wing pads, or winged adults, 

 have been found in colonies with this reproductive form. It probably 

 also breeds true to type. This type of reproductive form does not 

 leave the colony unless by subterranean tunnels. In species of Reticu- 

 litermes there is usually but little pigment to the body of this form; 

 there are only traces of eyes. This is no doubt due to the subter- 

 ranean mode of life of these termites. 



The reproductive forms of the species of the family Kalotermitidae, 

 including the genera Termojms, Kalotermes, Neotermes, and Crypto- 

 termes, which are not subterranean in habit, are always to be found 

 in the infested wood. Queens of the first and third forms have 

 commonly been found in colonies of species of Termopsis; typical 

 queens of the second form have not been commonly found but forms 

 with rudimentary wing pads are common (fig. 66, 1). Only one 

 queen of the third form has as yet been found in colonies of species 

 of Kalotermes (namely jouteli Banks). Queens of the first arid second 

 forms are not rare in species of the family Kalotermitidae. 



In the genera Termopsis and Kalotermes and ProrJiinotermes re- 

 productive individuals of the third form have marked pigment to 

 the body and eyes, unlike those in species of Reticulitermes. These 

 differences are explained by the fact that species of these genera 

 live above ground. 



Probably only the first form adults have image perception, but 

 the other castes (even workers and soldiers) may perceive light or 

 direction by means of the ocelli and reduced compound eyes. 

 (Thompson). 



No types of reproductive forms of Nearctic termites ever entirely 

 lose their power of locomotion, and there is no permanent royal ceU. 

 Their location in the colony will depend upon the season of the year 

 and geograpliical locality. During warm summer weather they are 

 usually within the more solid wood of infested trees, logs, and 

 stumps, and, strange to say, they are often in the outer layers of 

 wood. 



In the case of the wood-boring subterranean species, the reproduc- 

 tive forms may be found either in the earth or in the wood. During 

 warm weather they are usually above ground in the wood. In 

 winter they are below the frost line in the ground in cold climates. 



The burrows in the vicinity of the cell in which large mature 

 queens are present are of larger diameter than usual; these have 

 beeti used as passageways by the queen in coming up from the ground. 



Although their abdomens are slightly distended, the males of the 

 first form are very active; they are usually present in the royal cell
