tially inserted into the tissue and covered with a sticky, 

 brown substance, as in the species Corythuca arcuata cratcegi 

 Morrilland in the Christmas berry tingitid, 1 C. incurvata. The 

 oak tingitids lay their eggs free and erect, in smaller or larger 

 groups, fastened to the surface of the leaves. The sycamore 

 tingitid, C. ciliata, hides them beneath the pubescence on the 

 leaf. Eggs of the rhododendron species Leptobyrsa cxpla- 

 tuita 2 are inserted entirely into the epidermis of the leaf, pro- 

 tected there while hibernating. Eggs of the species C. mar- 

 moratit" are described as being thrust under the epidermis 

 along the larger veins of the leaf, leaving only the small, 

 yellowish, conical cap in sight. 



Leptostyla clitoriae, new species. 



Egg about 0.5 mm. in length; laid singly, upright, on the underside 

 of leaf; ovate, narrowing toward the lower egg pole; the chorion 

 thick and hard, covered with numerous coarse granules; color black, 

 except the lower end of the egg, which is whitish; chorial processes 

 channel-formed, arranged vertically around the extension of the rim 

 on inner side, continuing inside on the conical cap to its center. These 

 processes may be noticed even on the outside bulging as correspond- 

 ing narrow ripples, which are usually covered with a white substance. 

 (PL X, fig. 6.) 



Of the large family Capsidae (-= Miridse) eggs of only three 

 species are well known. The family is an ally of the 

 Reduviidae group, according to Leuckart, having the chorial 

 processes channel-formed on the inner side of the extended 

 rim. Slingerland, in his excellent essay on the lifehistor}' of 

 the four-lined leaf-bug P<.rcilocapsns lineatus* gives a detailed 

 account of the eggs. They are laid in slits cut into the stems 

 of the plants, closely packed together, usually in number of 6 

 to 8 eggs. The egg-scars, with the white tips of the eggs 

 projecting from them, are quite easily seen. He describes 

 the egg as follows: 



Egg, 1.65 mm. in length, smooth, cylindrical, slightly curved or 

 flask-shaped, and of a light yellow color with the upper third capped 

 by a white, finely striated portion; the lower end is rounded and the 

 upper irregularly flattened.
