REPORT OF THE STATE ENTOMOLOGIST I917 IO3 



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- 

 son i 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, R u m e x 

 c r i s p u s , 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 1 states that this species 

 occurs in the swollen buds of sheep sorrel, Rumex acetosella, 

 from which adults may be easily reared.

 This midge was taken at Albany, N. Y., June 21, 1906 on hard 

 pine, Pinus rigida.

 thickly fine-haired, dark brown; 14 segments, the fifth with stems 

 one and one-half and two and one-half times their diameters, 

 respectively. Palpi; the first segment short, obconic, second one-half 

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

 than the third; basal antennal segment and face fuscous yellowish. 

 Mesonotum dark brown, submedian lines sparsely haired. Scutellum 

 dark brown with sparse apical setae, postscutellum dark brown.
