REVISION" OF NEARCTIC TERMITES. 159 



16 mm. in length and 2.5 to 4 mm. in width, according to whether 

 the body was distended or contracted in crawUng. The male was 

 attracted to the female, although not fomid with her. The queen was 

 in a cell in the outer layers of wood. Numerous eggs and young were 

 present. 



In this same woodlot a male of the first form was found in a cell 

 near a knot in a decaying pine stump. No queen was found, although 

 very large egg clusters were present. Undoubtedly this male is a 

 mature king, and the queen escaped or was crushed. 



On August 19, 1918, M. A. Murray found a mature first-form king 

 oi Jlavipes in a large colony in a decayed chestnut stump at Chain 

 Bridge, Virginia. No queen was found; there were young in the 

 colony. 



On April 21, 1919, a very early record for the occurrence above 

 ground of reproductive forms oi Jlavipes was noted. In a decayed 

 stump, about 1 foot high, 29 females of the second form were found; 14 

 of these females had their abdomens distended (the largest queens 

 being 8 mm. in length), evidently had been fertilized, and were egg 

 laying queens. The abdomens of 15 were undistended and they might 

 easily have been mistaken for males. These females had the usual 

 pigmentation of reproductive individuals of the second form, and 

 there were no anal appendices present. There were 15 to 18 segments 

 to the antennae and the eyes were sUghtly pigmented. Several fe- 

 males had longer wing pads than is usual. No second form males 

 were captured or observed. Young were present in this colony. 

 About one-haK dozen winged, pigmented first-form adults were also 

 present; both sexes were represented — 6 females and 2 males. 



It is a question whether these queens with distended abdomens are 

 young and were produced this year contemporaneously with the 

 winged first-form adults, or whether they are the parents of the entire 

 colony. 



On April 30 M. A. Murray found a first-form queen in a colony at 

 Falls Church, Virginia. This is an early record for the finding of a 

 queen above ground. The colony was in a decayed pine stump and 

 was not large; 676 workers, 65 soldiers, 30 nymphs of reproductive 

 forms and 26 young. This was just after the swarm. 



The queen had a distended abdomen and is 12 mm. in length 

 (measured after being preserved in alcohol). There are 14 segments 

 to the antennae. 



While all of the first-form queens which have been found, with 

 few exceptions, were of large size, none of them were over 14i mm. 

 in length when measured living. 



It wiU be seen from these notes and what has already been pub- 

 lished that first form reproductive individuals are not rare in colo- 

 nies oi Havipes in the eastern United States,
