cases when full-fed it quits its mine and falls to the ground, 

 and pupizes there ; when it is confined in a breeding-jar it 

 only occasionally goes into the earth, in most instances con- 

 structing its cocoon in its mine. The larva when touched or 

 annoyed has not the power of emitting a viscid fluid from its 

 lateral pores. The perfect insects may be found amongst 

 sallows about the 20th of May and during the month of 

 June ; the first larvae begin feeding between the 20lh and 

 25th of the following July, and from that time down to the 

 end of October there is a constant succession of larvae; the 

 later-feeding larvae do not produce perfect insects till the 

 following season, and no imagos are developed after the 

 early part of October. — Charles Healy ; 74, Napier Street,

A Life-history of Phyllotoma Tormentilke. — The perfect 

 insects of this species are observed to frequent plants of Tor- 

 mentilla reptans about the middle of March, and anyone 

 examining such plants at the end of May or the beginning 

 of June will be certain to see a number of minute black 

 spots on the leaves ; these spots are the birth-places of the 

 little larvae, discoloured by " frass :" as the larva grows older 

 it forms a narrow, somewhat contorted, Nepticula-like mine, 

 about a quarter of an inch in length, having a narrow track 

 of "frass" running through its centre; by and by the larva 

 begins to make a small greenish white blotch, and if we 

 pluck one of the leaves so marked we shall find, on holding 

 it up to the light, that the blotch contains a minute white- 

 coloured larva, having a faint tinge of green imparted to its 

 body by the green dorsal fluid ; we shall further observe 

 •that the little creature has a pale brown-coloured head, that 

 its mouth is darker and its eye-spots black, that the back 

 of the 2nd segment is pale brown, that the larva feeds lying 

 on its back, that it is possessed of twenty-two legs, namely, 

 six thoracic, fomleen ventral and two anal, and that the 

 5th and 13th segments are apodal ; it is also perceived 

 that its ventral surface diflers greatly from its dorsal, in its 

 decorations the under side of the 2nd segment having a 

 black somewhat X-shaped plate, its 3rd, 4th and 5th seg- 

 ments each possessing a small black circular-shaped plate, 

 the articulations of the six thoracic legs being encircled 

 with pale brown-coloured bands. At this period of its
