abdomen more elongate, the sides of thorax not dilated and without the 

 fringing of hairs, as in previous species. 



Pupa. — Length .12 to .14 inch. Elongate, oval. Pale greenish yel- 

 low. Eyes brownish, prominent and situated further forward than in 

 previous species ; wing cases not so broad, obtusely rounded before and 

 not projecting forward towards eyes ; abdomen more elongate and notched 

 posteriorly ; legs pale ; and is easily recognized by not being pubescent 



Imago. — ^ and $. Length .12 inch; wing .14. Pale greenish 

 yellow. Head transverse, not projecting much in front, and with a frontal 

 notch, but not deep ; three remote yellow ocelli, situated on yellow 

 ground, two close to but back of eyes, and one in front between antennae ; 

 eyes large and prominent j antennae lo-jointed, filiform, reaching beyond 

 tip of thorax, two basal joints short and stout, pale to tip of 6th, following 

 joints black ; collare transverse, very short, prccscutum broadly obcordate ; 

 mesothorax has two large deep lateral depressions, extending backwards 

 towards scutellum, with a slight central groove ; scutellum triangular ; 

 abdomen elongate, pointed ; wings hyaline, lanceolate, veins pale green- 

 ish ; legs, epimeral spines and metasternum pale greenish yellow ; basal 

 tarsal joint broadly flattened. The usual structural differences distinguish 

 the male. 



THE ILEX PSYLLA. 



During a recent short trip to the sea shore, my attention was called 

 (by my friend, Mr. Curtiss) to a gall on Ilex cassi?ie, a shrubby tree grow- 

 ing in the tich hammocks along our coasts. These were found on the 

 terminal new leaves, measured from .2 to .3 of an inch in length, and 

 frequently destroyed the whole shape of the leaf Cutting these open, I 

 found they were caused by a Psylla, and judging from the size of the 

 pupa, is probably the smallest species known. In the galls the young 

 were covered with a mealy powder, very much resembling certain 

 Coccides, and when disturbed do not appear to secrete the watery 

 globules noticed in the previously described species. Below I give 

 description of the stages as far as ascertained : 



12. Psylla ilecis, n. sp. 



Young Larva. — Length less than .01 inch, oval, flattened, yellow and 

 pulverulent, with reddish eyes and pale legs. 



Pupa. — Length scarcely .03 inch. Yellow, pulverulent ; legs and 

 antenna pale, wing cases well developed and obliquely projecting on 

 either side ; abdomen rounded.
