red; wings relatively large and broad; fifth antennal segment with 

 a length two and one half times its diameter. Type Cecid. al950. 



Caryomia carycB 0. S., C. Iwlotricha 0. S., C. sanguinolenta 0. S., 

 and C. tuhicola 0. S., all formerly referred to Cecidomyia and later 

 to Hormomyia, have also been reared and described. 



Clinodiplosis caryce Felt was first taken on hickory June 19, 1906, 

 and subsequently reared from a hickory leaf gall by the late Dr. M. 

 T. Thompson of "Worcester, ]Mass., and last spring was obtained in this 

 office from two different hickory leaf galls. This species is probably 

 an inquiline in hickory galLs produced by several species of Caryomyia. 



Clinodiplosis spirce n. sp. was reared in July and August, 1909, 

 from a variable yellowish or reddish marginal roll on young leaves 

 of Spiraa salicifolia taken by ]\Iiss Cora H. Clarke at ^lagnolia, ]\lass. 

 ]\rale 1 mm. long ; abdomen yellowish, with its extremities deep orange ; 

 ventral plate long, narrowly rounded; fifth antennal segment with 

 the stems respectively two and two and one half times their diameter. 

 Type Cecid. al838. 



NOTES ON ADDITIONAL INSECTS ON CULTIVATED 



PECANS 

 By Glenn W. Herrick, and R. W. Harned 



The senior author has been working for a number of years on in- 

 sects affecting pecans, and since the publication of Bulletin 96 on 

 Insects Injurious to Pecans by the Mississippi Experiment Station, 

 the following insects have been noted as occurring on pecan trees and 

 causing more or less injury. 



Acordulecera maura MacG. 



We have found numbers of these sawfly larvte on the leaves of pecan 

 trees at Agricultural College, IMississippi. They have a curious and 

 interesting method of feeding. They are gregarious and feed on the 

 leaflets in ranks or rows along the margins, with their bodies at right 

 angles to the edges of the leaflets and their heads all pointing out- 

 ward. They line up along the edge of a leaf in this position, quite as 

 regular as a line of soldiers. They do not invariably assume this reg- 

 ular position in feeding and are sometimes found feeding irregularly 

 over the leaves. 



Fortunately these larvae did not occur in sufficient numbers to pro- 

 duce serious injury, but it is quite possible they may do so. So far 

 as we know, these sawflies constitute a new pest to pecan trees, al-
