median line of the back are yellow, and each emits a single black bristle ; then fol- 

 lows a longitudinal series of three white dots, and then a single yellow dot emitting a 

 black bristle, and below this yellow dot is a spiracle, oblong, white, and black- 

 margined ; anterior to the spiracle and in a line therewith are two white dots, and 

 posterior to these one yellow dot emitting a black bristle and one white dot; behind 

 the last spiracle, and extending along the edge of the anal flap, is a bent white line, 

 in which are two conspicuous yellow dots, larger than either of those previously men- 

 tioned : the legs are rather long, green tinged with red-brown ; the claspers apple- 

 green, with a shield-shaped mark in black outline on each. Feeds on Bettda alba 

 (birch), and is full fed rather before the middle of June, when it measures rather more 

 than two inches in length ; it then goes into the earth, concealing itself just beneath 

 the surface : the perfect insect appears at the end of March or the beginning of April, 

 and, as far as the British Isles are concerned, has hitherto been found only in Scot- 

 land. I am 'indebted to Mr. Greening, of Warrington, for the opportunity of de- 

 scribing the larva of this species : in confinement it rarely attains the perfect state, 

 most commonly dying as soon as full fed. — Edward Newman. 



Capture of Heliothis peltigera. — Perhaps it may be interesting to your readers to 

 hear that I have captured, during the last three weeks, three beautiful specimens of 

 Heliothis peltigera. Mr. Terry has also captured others in first-rate condition. 

 Among my other best captures this year I may mention — one Deilephila Livornica, 

 several Agrotis lunigera, and about a dozen Dianthecia conspersa. I have also taken 

 two beautiful Heliothis mavginata. — R. M. Steward.

After the careful researches of Ratzeburg, there remains but little 

 new or unknown to record concerning this insect ; but as this author 

 does not mention the points in which the young larvae differ from the 

 full-grown, we hope our descriptions and figure will not be looked 

 upon as wholly uncalled for. 



The imagos are found in May and June (fig. 6 represents a female,
