plaiit. I was, therefore, pleased to see that some of them occasionally 

 applied the tip of the rostrum to the grass leaves and apparently fed 

 upon their juices. On May 28th the first eggs were laid, and others 

 followed at intervals during the first week in June, till I had a batch 

 of something over two dozen. They were attached to the grass leaves 

 by a little adhesive secretion at the middle of one side. 



When first laid the eggs are pale yellowish, but later they become 

 honey yellow, and finally almost brown. The surface is shining. The 

 egg is of a long cylindrical shape, slightly tapering posteriorly, and 

 furnished anteriorly with a circle of half-a-dozen minute button-shaped 

 prominences, each with a depression in the centre, and probably micro- 

 pylar in function. When the egg is attached to its support, the whole 

 of the visible surface is found to be longitudinally deeply sulcate ; the 

 furrows are few in number and the ridges between them are convex. 

 The furrows and ridges are continued up to the circle of prominences, 

 but not beyond them. The egg is barely 1~ mm. in length. 



Apparently the eggs were kept a little too dry, and several there- 

 fore failed to hatch, although the fully-formed embryos could be seen 

 within. Two died in the act of emergence, being unable to set their 

 long legs quite free, and two eggs proved infertile. The rest hatched 

 out successfully. I had expected that, in hatching, the integument of 

 the small area within the circle of micropylar points would be pushed 

 off as a cap, as this method occurs very frequently amongst the 

 Hemiptera. But such did not turn out to be the case. The egg-shell 

 merely split longitudinally at the anterior end and the embryo pushed 

 its way out through the opening, but without casting off any part of 

 the shell. 



The first eggs hatched on June 19tli, thus giving a period of three 

 weeks for the duration of the egg condition. The larvae in their first 

 instar differ markedly in several respects from the adult, and are 

 furnished with certain provisional structures which entirely disappear 

 at the first ecdysis. The newly-hatched bug has a small nari-ow 

 cylindrical body and very long legs and antennae. The fore parts are 

 almost coloui'less except for a dark greyish streak on each side. The 

 abdomen is pale green with black tubercles on the dorsal surface, from 

 each of which proceeds a long, colourless, stoutish hair, ending in a 

 brilUant crystal globule. The black spots are arranged so that there 

 are four on each segment, the two anterior ones being closer together 

 than the posterior, so that they form a regular pattern down the body. 

 The rest of the dorsal surface is furnished with similar hairs, which 

 do not, however, proceed from black tubercles. The eyes are bright
