dG Mr. N. Armandale on the 



During the night between August 18th and 19th, each 

 egg produced a young Heteropteron. The operculum was 

 pushed out bodily and did not remain attached at any 

 point to the remainder of the egg-shell. What I take to 

 be the embryonic exuviae were left hanging from the upper 

 part of the aperture thus formed in a heart-shaped mass, 

 the free apex of which was produced into a delicate 

 filament. The mass was also attached to the base of the 

 egg-shell by a stouter filament, which originated above 

 as a ridge on the inner surface of the mass. On the 

 external lace was a very conspicuous black spot, the nature 

 of which I have been unable to determine. 



In what manner the operculum was pushed out I cannot 

 say, as I did not see the hatching. It appeared to be very 

 firmly attached to the remainder of the shell although its 

 limits were clearly defined to the eye. There was nothing 

 of the nature of a hardened projection on the head of the 

 larva when hatched. 



The young bugs in their first instar measured 4*5 mm. 

 in length. There was no visible difference in size between 

 the different individuals of the brood. The head was 

 squarish, but slightly rounded behind ; the eyes were fairly 

 large, but not prominent; I could detect no ocelli. At 

 first sight the antennae appeared to be five-jointed, but a 

 closer examination showed that the first apparent joint 

 was really a projection from the head : they were inserted 

 into the upper part of the head. The rostrum originated 

 close to the anterior margin of the head and was freely 

 movable ; only three joints could be detected in it with 

 certainty. The tarsi appeared to have only two joints. 

 The form and proportions of the different parts of the body 

 are well shown in fig. 4. The colour was leaf-green, 

 marked with purplish-brown, which changed to olive-green 

 on the extremities of the limbs and antennae. The dorsal 

 "stink-glands" were rendered conspicuous by their promi- 

 nence and dark colour. 



The larvae were sluggish, but they fed readily on the 

 juices of various leaves, standing with their rostra vertically 

 inserted into the vascular parts of the leaves, generally 

 into the midrib. Their abdomens rapidly became almost 

 globular. 



During the night between August 21st and 22nd, the 

 first ecdysis took place. A remarkable change both in 

 structure and demeanour was at once apparent. The larva?
