Xll MONTHLY TROCEEDINGS 



extending from middle of mesothorax forward to collare in straight line with 

 outer ocelli, parapsidal grooves distinct, brownish-black, two small grooves be- 

 tween these and just back of the black vittse, converging towards scutellum not 

 quite reaching hinder edge; the grooves are blackish and also the surface of the 

 mesothorax a short distance along their edge ; scutellum roundish, punctate and 

 pubescent ; wings hyaline, veins brownish all strongly defined, radial area nearly 

 closed, areolet closed, the closing vein very pale,- legs a clear amber pubescent; 

 abdomen dark brown, smooth and shining basal part of the second segment 

 reddish. 



Described from one bred specimen. 



Thr Leafy Gall of (he Live Oak. 



Another curious and by far the most interesting gall I have yet found 

 in Florida, is that to which I have given the above name. Growing as 

 it does in the bud axil of the leaf, and not unfrequently iu close proximity 

 to the others, the gall would naturally be taken by most observers for 

 the blossom of the oak ; indeed I never until lately suspected it to be 

 the product of a Ct/nips. 



On page 72, vol. 2, of " The American Entomologist," is figured a gall 

 discovered by II. F. Bassett, so well known for his researches in this 

 interesting branch of entomology, which will give one a fair idea of the 

 species under consideration. 



At first I was inclined to believe my species and his, which he calls 

 Cj/nlps frondom identical; but on a careful study of his description of 

 the gall, (he does not characterize the insect producing it), I have no 

 hesitancy in describing it as new. 



Mr. Bassett found his species at Watcrbury, Conn., on the Chincjuapin 

 Oak, Q. prlnoldeSj while Walsh found it on the Bur Oak and White 

 Oak; vide Proc. Entom. Soc. Phil. p. G8, 18G4-. 



He says : " When mature it often attains a diameter of two and a 

 quarter inches, and the modified leaves of which it is composed are then 

 much longer and proportionally much wider than at first, so that instead 

 of being what the botanists term ' lanceolate,' they become oval with 

 their tips usually acute." 



Bassett says : " The cells containing the larva are smooth, shining, 

 oval, about one-eighth of an inch long." 



Walsh also says : " The larger ones enclose four or five cells and when 

 the gall becomes mature, the cells are gradually disengaged from their 

 leafy matrix and drop to the ground, where no doubt the larva will pass 

 the winter more agreeably among the masses of dead leaves, which 

 accumulate in such situations, than it would do if it were exposed aloft 

 to the stormy blasts, and the cold driving sleets of the dead season of 

 the year." ,
