The queens of the species of Reticulitermes do not reach extraordi- 

 nary size and never lose the power of locomotion. They probably 

 change their location in the colony to conform to the most favorable 

 conditions of temperature and moisture and go below the frost line in 

 the gromid in winter. There is no permanent, centrally located 

 royal cell. The largest queen oi jiavifes so far foimd was of the first 

 form and was 14^ mm. in length and 4 mm. in width, measured Mdiile 

 living. The attendant males have the abdomens slightly distended. 

 The largest queen of the second form measured 12 mm. in length 

 (alcohohc specimen), and the largest third form queen was 7 mm. in 

 length, measured while living. 



The finding of these reproductive forms and the conditions under 

 which they occur in colonies have aheady been discussed in previous 

 papers. A few additional later findings will be recorded. 



On April 29, 1915, Dr. H. von Schrenk found five queens of the 

 second form of R.fiavifes in the decayed wood at the base of a white 

 cedar telephone pole at St. Louis, Missouri. The antemiae consisted 

 of 14-15 segments, there was pigmentation to compound eyes, abdo- 

 mens were distended irregularly, distorted in outline, lumpy due to 

 being unevenly distended, the pigmentation was pale bro\Mi or grey, 

 length 8^ to 10 mm. ; wing pads were as in nymphs of the second form. 



On May 15, 1915, Prof. W. M. Wheeler found a large queen and a 

 king of the first form oijiavipes at Blue Hills near Boston, Massachu- 

 setts. This queen was 10 mm. in length with the abdomen markedly 

 distended. 



On July 26, 1915, a first form or "true" queen (jlavipes) 13 mm. in 

 length and a king 6.5 mm. in length were found by the writer at Falls 

 Church, Virginia, in a decaying tulip tree stump, in a longitudinal 

 royal cell, the burrows leading to the royal cell being round and of a 

 diameter as large as the distended abdomen of the queen. 



Durmg an inspection of telephone poles, from October 15 to 26, 

 1915, near Savannah, Georgia, several reproductive forms were found 

 in the bases of the poles. A queen of the first form 10 mm. in length 

 (measured after being preserved in alcohol) with distended abdomen, 

 was found in one colony oijiavipes, and four queens and five males of 

 the second form, the queens having distended abdomens, the largest 

 female being 8 mm. in length (measured after preserving) in another 

 colony. 



On June 23, 1916, at Dead Run, Virginia, a first form queen of 

 jlavipes was found by the writer in a cell in an oak stump in the more 

 solid outer layers of wood, about 1 foot from the ground. This queen 

 was 15 mm. in length and 4 mm. in width (measured after preserved 

 in alcohol). 



On March 28, 1917, C. A. Mosier and the writer found a colony of 

 jlavipes in a decaying log on Long Key, in the Lower Everglades of 

 Florida, in pineland. This colony contained young reproductive
