species of Metapodius 1 and in Euthoctha galeator. 2 It is in- 

 teresting to note in this family the peculiar arrangement of 

 the chorial processes, which encircle the egg so that they pass 

 nearly midway over the cap as a row of small, extremely low 

 knobs with a dark center. 



In eggs of Metapodius fenwratus these knobs are whitish 

 and in the center reddish-brown; there are at least 40 such 

 processes (PI. IX, fig. 5). Those of Euthoctha galeator num- 

 ber about 22. The common squash-bug, Anasa tristis? has 15 

 to 18. Eggs of Spartocerus diffusus (PI. IX, fig. 6) and Meta- 

 podius femoratus are much alike; the former differs in having 

 the chorial processes farther apart and, of course, less numer- 

 ous. The surface of the eggs of the Coreidse is usually finely 

 reticulated. A somewhat aberrant form of a coreid egg 

 appears in species of the genus Leptoglossus." This probably 

 is caused by the mode of laying the eggs in a string in firm 

 contact with each other at the ends, whereby the sides of the 

 egg become flattened. In Lcptoglossus magnolia* the eggs 

 have a metallic, copper-like lustre, and the surface of the 

 chorion is finely shagreened. The chorial processes number 

 from 16 to 18 (PI. IX, fig. 7). 



The eggs of Archimerus calcarator are laid in a row, but 

 not joined at their ends; they are broader than high, nearly 

 3 mm. long and 1.5 mm. in width. The color is dark brown. 

 The chorion very finely reticulated, with about 14 chorial 

 processes, which are also dark brown (PI. IX, fig. 8). These 

 eggs seem to be an intermediate form towards the eggs of 

 Leptoglossus species. 



Veiy small eggs of a coreid are those in species of the 

 genus Corizus. In Corizns side? these eggs are not quite 1 

 mm. in length. The general form is the same as in all eggs 

 of this family, except that, seen from above, they have a 

 somewhat triangular indentation just behind the cap. The 

 color is dark brown, nearly black, with a few reddish marks, 

 and the surface of the chorion irregular, strongly punctured; 

 chorial processes are only a few (PI. IX, fig. 9). The egg- 

 burster in this family differs from that of the Pentatomidse 

 merely in having a more prominent dark tubercle at the 

 middle of the crossbar.
