slightly nearer base. Claw- joint of mid-tarsi only slightly excavated, 

 claws same as of anterior tarsi. Posterior claw-joint normal, very small, 

 with simple claws of same size. 



Female anterior and mid claw- joints alike, single tooth on each of 

 claws. Posterior joint of same size, claws simple, as in male. 



Abdomen dark brownish black, yellowish white bands at base of each 

 segment, considerably narrowed centrally. Bands become wide laterally, 

 more noticeable posteriorly, and at segment seven broaden to entirely 

 cover dorsal surface. Beneath, entire surface pale yellow. 



HABITS OF THE ADULT 



This species was not recognized as distinct until 1903, but was con- 

 fused with both stimidans and vexans. It was this fact that prevented 

 its recognition as a migrant in 1902, when I first met with the species 

 in great numbers and found it as early as April, the dominant form in 

 South Orange. In 1903 as early as March 23, larvae were well advanced 

 at the edge of the Newark marsh, and adults began to issue during the 

 early days of April. But it was not until the last days of the month 

 that the bulk of the brood began to issue, and during the early days of 

 May the migration was on in full force. May 12 they had reached South 

 Orange, and by the middle of the month the entire countryside was cov- 

 ered with them. A second and much larger brood became started on the 

 marshes late in May, and before the end of June was fully a-wing. Mi- 

 gration began during the last days of June and, north and west, local- 

 ity after locality was covered to an extent greater than usual. Sollici- 

 tans was also in this swarm which filled the cities and towns bordering 

 on the marsh as they had rarely been filled before. 



On the morning of July 2, I was met when I stepped outdoors by a 

 famished horde containing sollicitans, taeniorhynchus, and cantator. 

 The preceding evening we had sat comfortably out on the porch, with- 

 out disturbance from mosquitoes. The incoming horde settled the com- 

 fort for weeks thereafter. This same brood was traced to Plainfield, 

 Dunellen, Bound Brook, and Somerville, where the migratory forms 

 rarely get. The Newark swarm was traced to Summit and Morristown, 

 and may have extended further. 



In 1904 marsh conditions favored the early brood, and unusual 

 swarms developed on the Raritan, Elizabeth, and Newark meadows 

 early in May. By May 10 the whole marsh area was a-wIng, except 

 along the Shrewsbury, where the work done by the Monmouth Beach 

 and Rumson Neck Associations completely annihilated the immense 

 brood that was developing. The ditches were completed just in time to
