extension of the rim shows the chorial processes plainly; outer 

 surface very fine granulate, pearly white. (PI. XII, fig. 5). 



The egg of Zeliis Inr/diis is originally described and figured 

 by Kirkland 1 in his notes on the life history and habits of 

 certain predaceous Heteroptera. The sticky secretion the in- 

 sect uses for protecting its eggs covers sometimes also the cap, 

 leaving only in the center a small opening; chorial processes 

 close together, club-shaped. (PI. XI, fig. 3.) 



Sinea dtadema.l&gg 1 mm. in length; ovate-elongate; 

 color light brown; outer surface fine granulated; the exten- 

 sion of the chorion at the outside rim consists of numerous 

 yellowish, short and longer scales, turning down over the egg 

 like a beautiful Dutch collar; cap considerably raised, narrow- 

 ing and rounding at top, resembling somewhat the cap of an 

 oak tingitid. (PL XII, fig. 4.) 



Apiomerus crassipes. Egg 1.8 mm., oval-elongate; color 

 dark brown; the extension of the chorion at upper egg-pole 

 composed of longitudinal fine scales connecting with each 

 other, yellowish around the rim and white at the edge; the 

 cap rather low, crowned with white scales, of which those on 

 the inside circumference are brown. (PL XI, fig. 2.) 



Eggs of Arilus cristatns have been described and figured 

 by Glover in his manuscript notes, page 61, 1876 (Hemiptera- 

 Heteroptera). The eggs are oval-elongate; dark brown; 

 chorial processes inside of the extended rim, club-shaped.

A most interesting article has been published by J. 

 Fabre, 3 in his Souvenirs Entomologiques, on the egg of the 

 cosmopolitan species Reduz'ias personates. He observed a 

 young larva in the act of emerging from its egg. The follow- 

 ing is a translation. 



". . . The opening of the cover widens and through the crack I 

 perceive something shining. It is an iridescent skin, globe-like, that 

 pushes the cover. Now emerges out of the shell a spherical vesicle, 

 which, by degrees, enlarges itself like a soap-bubble, blown at the end 

 of a straw. More and more, pushed by the enlargement of the blad- 

 der, the cover is displaced. Then the bomb explodes, that is to say 

 that, swollen beyond the limits of its resistance, the bubble ruptures at 

 its summit. This envelope-membrane of extreme tenuity remains, 

 generally adhering to the brim of the orifice, where it makes a high 

 and white margin. At other times the explosion detaches it and
