6 S and 4 9 serratus emerged July 30th, and 5 9 emerged 

 August I St. Some of the larvae pupated July 31st, and Aug- 

 ust 3d, 2 9 serratus emerged, so that the connection between 

 the white-banded larva and serratus adults was fully estab- 

 lished. The determination of the adult was suggested doubt- 

 fully by Mr. Dickerson and confirmed, independently, by Mr. 

 D. W. Coquillett. August 13th another lot of mixed larvae 

 and pupae were brought in. One full-grown larva was isolated 

 and pupated a few minutes later, leaving a larval skin which 

 was mounted in balsam. Adult from this pupa issued August 

 19th — a vsix-day pupal period. Other adults from the mixed 

 lot of pupae emerged August 15th, — 6 % and i 9 . 



A few larvae were collected September 3d, and then the pools 

 dried up : adults were taken in the w^oods, near the dried-up 

 pools, September 14th. Rain having filled the pools soon 

 after, another collection was made September 30th, containing 

 larvae and pupae. Adults emerged : 2 (? , i 9 , October 3d ; 



7 (? , 9 9 , October 5th. 



While collecting in the woodland pools of the Great Piece 

 Meadow, an extensive Swamp area bordering the Passaic 

 River, Mr. John Grossbeck took serratus larvae, full and half 

 grown, September 9th and loth. Pupation began September 

 1 2th, and the first adult emerged September lytli. Others 

 emerged September 21st, before the culture was closed. An- 

 other lot of mixed pupae was taken September nth, and 7 % 

 and I 9 serratus emerged during the two days following. 



During early September, Mr. Henry L. Viereck took adult 

 serratus at Cape May Point, but did not find the larvae. 



The species therefore ranges the full length of the State of 

 New Jersey, probably breeding nearly or quite always in tem- 

 porary woodland pools, while the adults rarely leave the 

 vicinity of the places that gave them birth. It is certain that 

 I never received any with the miscellaneous lot of material 

 collected near and in towns and villages. 



The larva is well shown by figure 2, and is 6-7 mm. in 

 length excluding the anal siphon. The head is dark brown, 

 widest at the eyes, tapering anteriorly and somewhat flattened 

 in front. Antennae not quite half the length of the head,
