exposed to the light there would be pigment in the body tissue. 



In case of species Termopsis, which are not subterranean in 

 habit, third form adults, which are found in colonies, have deeper 

 pigment to the body and portions of compound eyes are present. 

 Offshoot colonies may be established in the same log or even in 

 nearby logs by these third form adults. 



Third form adults of Prorhinotermes simplex Hagen have a deep 

 pigmentation to the body and have both eyes and ocelli; hence 

 these reproductive forms are capable of coming out of parent 

 colonies in infested logs into the full sunlight and establish new 

 colonies in nearby logs. The deeply pigmented apterous adults of 

 species of Zorotypus may do likewise ; it is not yet proved whether 

 Zorotypus is a social insect with a caste system, or not, i. e., lives 

 in colonies or is merely gregarious and lives in communities. If 

 the latter is true, of course the migration would necessarily not 

 be accompanied by workers. Much of this, however, is conjec- 

 ture. 



Third form adults of termites, like adults of the second form, are 

 polygamous, there being a large number of females to a small 

 number of males. The presence of either of the two types of third 

 form reproductive adults of Zorotypus in large numbers in the 

 same community indicates that the habit of polygamy likewise 

 occurs in case of apterous adults in the order Zoraptera. 



Results of Breeding Experiments. 



The preliminary results of breeding experiments conducted 

 with species of Reticulitermes, Neotermes and Termopsis have al- 

 ready been briefly outlined in previous papers, (Snyder, 1915, 

 Thompson and Snyder, 1919, and Banks and Snyder, 1920). A 

 more detailed account will be given herewith. Heath (1903) has 

 described breeding experiments conducted with species of Reticu- 

 litermes and Termopsis; some of Heath's results need further 

 elucidation. 



Feytaud (1912) has published the results of his breeding ex- 

 periments with Reticulitermes lucifugus Rossi; Feytaud's results 

 differing somewhat from those obtained by the writer with other 

 species of Reticulitermes in the United States; unlike in the writ- 

 er's experiments, no soldiers were reared in his incipent colonies. 



Wheeler (1907) states that: "In incipient ant colonies, the queen 

 mother takes no food, often for as long a period as eight or nine 

 months, and during all this time is compelled to feed her first 

 brood of larvae exclusively on the excretions of her salivary 

 glands. This diet, which is purely qualitative, though very lim- 

 ited in quantity, produces only workers, and these of an extremely 

 small size (micrergates)."
