 paler streaks ; an abbreviated transverse black partly cinereous-bordered line beyond 

 tlie middle ; a more exterior whitish dentate transverse lino ; marginal line black ; 

 fringe cinereous ; costa mostly black. Hind-wings blackish, reddish at the base.

My specimen agrees with his dark reddish-brown variety ; he 

 might have added that the posterior pox'tion of the thorax and the 

 base of the abdomen are whitish-ochreous ; the legs are rich ferrugi- 

 nous-brown, the basal portion of each joint slightly paler ; the under- 

 side of the body whitish-ochreous, of the wings only slightly paler 

 than the upper-side.

In a former volume (I. c.) I described as L. lauri, Boisd., flat 

 scales found on bay leaves at Southampton and Lewisham, and although 

 early in the year, yet as there were young larva) beneath the largest 

 of them, I concluded they were mature. Early in October, 1890, 

 however, on leaves of the same bay tree at Lewisham, and on others 

 sent by Mr. Bignell, of Stonehouse, Devon, besides many young 

 insects, there were several scales of the preceding brood, dead and 

 empty, and these showed there had been a further development, for 

 although not of larger dimensions the median area had become plump, 

 smooth and brown, yet the lines radiating thence to the margins re- 

 mained and were black, and in all the scales, of every age, the eyes 

 were not black as in L. hesperidum. Adverting to Signoret's doubt if 

 L. lauri were distinct from L. hesperidum, I sent some of these bay 

 leaf scales, and also some of i. hesperidum from orange trees, to Mr. 

 E. Newstead, to prepare and mount for examination ; this he has had 

 the kindness to do, and to communicate the result, as follows : —
