median and 2nd lobe, two again, if not three, between 2nd and 3rd lobes, followed 

 by three or four more similar plates. The spines are as usual, but rather small, 

 situated one at the base of each lobe, and one further along the margin, indicating, 

 as I think, the limits of suppressed or rudimentary segments. Although it is 

 difficult to observe the spines at the base of the median lobes, the globular basal 

 point may be seen. The differences between the two species are very marked. 

 The characteristic peculiarity of this species consists in its plates, which are large, 

 branched antler-like. Moreover, it has four groups of ventral glands, whilst A. 

 rap aw has none. 



DiASPIS TENTACULATUS, n. Sp. 



? scale more or less circular, flat, greyish-white, with exuviae on one side 

 usually, but not projecting beyond the limits of the scale. The median posterior 

 lobes are convergent at the base, and divergent at the apex, and their inner lateral 

 margins serrate. The 2nd and 3rd lobes are ifn-lobed, and there is a 4th lobe, some- 

 what rudimentary. There is a simple unbranched plate between each set of lobes, 

 and beyond the 4th lobe there are several simple plates. The spines are very small, 

 and rather difficult to observe, but they appear to be in the usual positions, at the 

 base of the lobes. There are five groups of ventral glands, and between the pos- 

 terior groups is situated the anus. The anterior groups consist of about eight or 

 ten, and the lateral groups of about ten or fifteen glandular organs. 



The S scale is small, white, tricarinated, and of the usual shape and character 

 of male scales of the genus Diaspis.

DESCRIPTION OP THE LAEVA OF ORTROSIA SUSPECTA. 

 BT GEO. T. POEEITT, F.L.S. 



In 1S91, Orthosia suspecta seemed to be unusually abundant in 

 all its localities, and was especially so at York, where throughout 

 August it occurred in the utmost profusion. Mr. William Hewett, of 

 that city, obtained eggs from specimens he captured there, part of 

 which he very kindly sent to me, and part to Dr. Chapman, of Here- 

 ford. Mine, which I received on September 20th, were deposited in 

 a batch at the bottom of a chip box, and were of ordinary globular 

 form, very glossy and smooth, the colour pale pinkish-brown. They 

 were kept outdoors all winter, and at quite the end of April began to 

 hatch out. Unfortunately, I had to be in London at the time, and, 

 through my inability to properly attend to them there, all died, 

 fortunately, Dr. Chapman was more successful with his, and on May 

 18th, he very kindly let me have two larvae, which were then nearly 

 full-grown, and I described them at once as follows : — 



Length, when at rest, about three-quarters, when crawling, seven-eighths, of an 

 inch, and moderately plump in proportion ; head small and polished, the lobes 

 rounded ; it is rather narrower than the second, and considerably narrower than the
