of females. The reproductive forms were not ail together, but grouped 

 in lots of half dozen or more in chambers in different parts of the log. 

 Eggs were very numerous in this colony; they were in large clusters 

 in different parts of the log. 



The females had distended abdomens, the largest being 10 mm. in 

 length; the average length was 8.2 mm. The pigmentation was of 

 the characteristic grey-brown color of this form; there were 17 seg- 

 ments to the antennae. One female had a black band of fungus on 

 an abdominal tergite. Njmaphs with short wing pads were present 

 in the colony; they are probabl}^ of the second form. 



On July 9, 1918, at Falls Church, Virginia, R. A. St. George and 

 the writer found enlarged third form queens in a large colony of 

 jiavipes in a decayed Virginia scrub pine stump about 3 to 4 inches 

 above the ground. This was about noon and some of the queens 

 were exposed by the first blow of the hatchet; 17 queens wore pres- 

 ent; the largest queens were 9.5 mm. in length and 2,75 mm. in w^idth 

 measured while living. Wing pads were absent and the abdomens 

 of the queens were apparently more cyhndrical than those of the 

 second form. The pigmentation was of a light straw color; the an- 

 tennae had 16 segments. No males were recognized. 



Eggs in clusters and young were present. These eggs were ap- 

 parentl}^ not different from those laid by the queens of the first and 

 second forms. A few nymphs of the second form ( ?) with short 

 wing pads were in this colony. This is the greatest number of this 

 form of queen found in the United States, there being more pres- 

 ent than the total number previously found in ail species of 

 Nearctic Reticulitermes. 



Termitopliilous Stapiiylinid beetles were present in this colony. 



On July 18, 1918, a pair of first-form reproductive individuals was 

 found by tlie writer in a decayed stump at Falls Church, Virgmia. 

 The queen was not greatly enlarged, being under 14 mm. in lengtii 

 measured living. Eggs and young were present. 



At Veitch, Virginia, on July 26 R. A. St. George and the writer 

 found six enlarged second-form queens in a colony in a decaying 

 stump. Nymphs of the second form with short wing pads were pres- 

 ent in tills colony. Eggs and young were in the colon}'. 



The writer found a large first-form queen of Jiavijjcs witli attending 

 male in the partly decayed root of a living oak tree at Falls Church 

 on August 2. The queen was 12.5 mm. in length and 4.5 mm. in 

 width (measured living). Large clusters of eggs and young were 

 present. The termites had entered the root through tiie burrows of 

 a large Prionid beetle ; the colony was large. The male was attracted 

 to the female and remained with her in a cell in the more solid wood. 



In another nearlw colonv in a decayed pine stump a large queen 

 and attending male were found. The queen measured from 12.5 to
