leaf until, when all had arrived at the perfect state, she could no longer 

 be distinguished from her progeny. 



I do not know that the immature stages of this insect have ever been 

 described, and therefore subjoin a few notes concerning them. 



I did not have the opportunity of watching the process of oviposition, 

 and think it takes place mostly at night. The modus operajidi would 

 seem to be as follows : 



The midrib of the leaf is always selected, on the under side of which 

 the cuticle is ruptured by a series of punctures made probably with the 

 beak. The eggs, to the number of fifty to seventy-five, are then crowded 

 into the loose vegetable tissue in an oblique position. They are some- 

 what pear-shaped, the larger end being uppermost, and of a dingy white 

 color varying to pale brown. As with the eggs of many other insects they 

 seem to swell considerably before hatching. On escaping from the egg 

 the young leaf-hoppers are rather more than i mm. in length, of a trans- 

 lucent, pale, greenish-yellow color, with the head and prothoracic region 

 of a dark red-brown, a saddle-like spot of the same color across the 

 middle of the body and another at the tip of the abdomen, which is al- 

 ways held in an upward curve. The form from a dorsal view is some- 

 what tad-pole like, except for the long, slender legs. The head in front 

 is sparsely covered with hairs ; the eyes are large, ruby-red, surrounded 

 by a pale ring. The prothoracic joint is raised in front and there is a 

 double row of hair-like papilte extending along the dorsum. These larvae 

 grow quite rapidly and moult but twice previous to the change to pupa\ 

 In the latter the dorsal prothoracic projections characteristic of the mature 

 insect are clearly developed, but in a soft tissue which is notched finely 

 on the upper edge. The arrangement and color of the spots do not vary 

 much from those of the newly hatched larva?. The period of growth from 

 the egg to mature insect is about three weeks.

Life History of Euscirrhopterus Gloveri, Grt. 



In the "Industrialist," a paper published by the State Agricultural 

 College Kansas, under date of Oct. i, 1887, Prof. E. A. Popenoe gives 

 the life history of the above insect. The larva and pupa are described as 

 follows : 



"The &%% may be found on the underside of the purslane leaf, singly 

 or in clusters of two to five. It is a flattened hemisphere in form, about 

 one half millimeter in diameter, attached bv its flat side to the leaf; and
