horn blackish. Second moult, Aug. 29. — Larva grass-green; 

 dorsal area darker ; a narrow yellowish green dorsal line ; 

 subdorsal and spiracular lines pale yellow, edged with black 

 on the upper sides ; ten oval yellow spots, one on each seg- 

 ment, in the subdorsal line, between w^hich and the legs the 

 surface is profusely sprinkled with minute light-coloured 

 specks. Third moult, Sept. 3. — Many specimens of a deep 

 sea-green, some lighter and some darker; the dorsal area 

 always darkest; dorsal line greenish yellow; subdorsal and 

 spiracular lines yellow ; the ten oval spots larger and of an 

 orange colour; spiracles white; horn black, with the base 

 dirty yellow ; head grass-green ; edge of mouth black ; pro- 

 legs black ; some specimens entirely black, with the before- 

 mentioned coloured markings ; all have the whole surface 

 sprinkled with more distinct minute pale-coloured specks, 

 most numerous between the subdorsal line and legs. Fourth

Notes on Progress in British Lepidopterology during the 

 last few years, showing the advantages of working at 

 Specialities. — A few years ago some of our restless spirits, 

 having become blocked, so to speak, in their collections, 

 turned their attention to special families or genera, with the 

 following results. First the Eupitheciae were worked by the 

 northern collectors, and followed by a few more southern 

 men, closely and carefully, until they are now well known to 

 all practical entomologists : the new species which have 

 been added or differentiated speak well for the critical and 

 careful observations of our entomologists; and though there 

 remains one species to clear up in our list, there is but one 

 species, which has cast its shadow before it, likely to be 

 added in the present state of our knowledge. Closely 

 following the Eupitheciae, the genus Lithosia attracted the 

 attention of the northern men, and two species were added — 

 one new to Science, the other a well-known continental 

 species ; whilst two of our three rarest species were dis- 

 covered in profusion in the New Forest by two collectors 

 sent from here "prospecting;" and another species, having a 

 da*ik hairy larva with bright orange markings, has cast its 

 shadow before it from the Isle of Man. Then the clear-
