REPORT OF THE STATE ENTOMOLOGIST IQI7 103 
The eggs are undoubtedly laid in the developing flowers, the maggots 
forsaking the buds before they drop. The infestation is evidently 
very similar to the injury to grape buds by Contarinia john 2 
soni Sling. This cotton pest may be recognized by the greenish 
yellow abdomen, the dark-brown mesonotum and by the fifth 
antennal segment having the basal portion of the stem with a length 
two and one-half times its diameter, the distal part with a length 
four times its diameter; the fourth palpal segment is one-fourth 
longer than the third. A parasite, Zatropus deuterus 
Craw., has been reared from this midge.

Numerous reddish or brown seeds of curled dock, Rumex 
ecrispus, were taken by D. B. Young at Newport, N. Y., July 
18, 1907 and the above-named European species reared. Our 
provisional identification was kindly confirmed by L’Abbe J. J. 
Kieffer, a noted European authority in this group. 
Gall. Seeds infested by this species are reddish or brown, each 
containing a single larvae. Professor Trail! states that this species 
occurs in the swollen buds of sheep sorrel, Rumex acetosella, 
from which adults may be easily reared.

longer, third a little longer and the fourth fully one-half longer
