 times with a dot on either side. There is a small, black central dot on each 

 of the following segments, though they are often absent on the posterior 

 one. Length when full grown, 5 lines. The adult has been described by 

 Cameron as follows : 



Black, shining. Antennae short, stout, 

 covered with a stiff pile ; two first joints 

 together equal in length to the third, which is 

 twice longer than the fourth, the remaining 

 joints to the eighth shorter, the ninth joint 

 conical, longer than the preceding. Head a 

 little narrower than the thorax, scarcely pubes- 

 cent, shining, smooth, sutures moderately dis- 

 tinct ; labrum and mandibles piceous ; palpi 

 dark testaceous. Thorax shining, smooth, 

 glabrous ; tegulae black. Abdomen short, coni- 

 cal, thick, smooth, semitruncated at the apex :

 and tarsi, dark testaceous. Wings faintly 

 smoky ; first radial cellule a little smaller than

Brown tail moth 

 Eiiproctis clirysorrlioca Linn. 

 Small web tents on the tips of trees in midwinter very likely belong to this species, 

 particularly if small caterpillars are found within. 



This species does not at present occur in New York State, but it is 

 only a question of time before it will become established within our borders,
