potatoes in the hill, without being killed. I have noticed 

 that the spring brood confines itself more especially to 

 young cruciferous plants, such as cabbages, and also on 

 beets, spinach, etc., but have found the fall broods collect 

 in hundreds on the heads and flower-buds of asters, on 

 the Snow-berry or White-berry {Syni'plwricar'pus race- 

 mosus); on diiierent kinds of Honey-suckle, Mignonette, 

 and on Asparagus ; they are also said to occur on the 

 flowers of Clover, and are quite partial to the common 

 Lamb's-quarter, or Goosefoot {Chenopodium album). 

 On account of their gregarious habit when young, they 

 are very easily destroyed at this stage of their growth, 



A NEW CABBAGE WORM. 

 (Pionea rimosalis, Guen). 



Prof. Cyrus Thomas, Carbondale, wrote to the 

 '•'American Entomologist," in substance, as follows: " I 

 have something new. It is a new Cabbage worm, the 

 larva of Pionea [Orobena] rimosalis, Guen., which 

 appeared late the past season, remaining on the cabbages 

 till toward the end of November. It is very destructive, 

 doing as much injury to my cabbages after it appeared as 

 the imported Cabbage worm {Pieris rapce) which has 

 been very destructive here this season. The larva, when 

 full grown, is six or seven-tenths of an inch long (a 16- 

 legged Pyralid larva); slender, slightly flattened; head 

 shining greenish-yellow; dorsal portion of the body down 

 to the breathing pores purplish-brown; this portion 

 marked with numerous transverse whitish lines, two or 

 three to a segment; a narrow, pale yellow hne along the 

 region of the stigmata; underside pale green. In the 

 breeding cages they went down to the soil, but not into 

 it, to pupate; forming a slight, regularly shaped, oval 

 cocoon, thickly covered over with sand.
