of what I at present believe to be S. ambigualis, whilst I have 
others of this species very pale in colour. Some S. angustea 
vary much in depth of colouring, as also does S. murana, the 
colours of the vars. being darker than the type.—J. Turt;

DESCRIPTION OF THE LARVA OF CRAMBUS CONTAMINELLUS.— 
Last year I reared a few beautiful specimens of this insect; and, 
as so much interest pertains to the species just now, it may be 
advisable to place on record a description of the larve, which 
were found by Mr. W. H. B. Fletcher, of Worthing, feeding on 
either Poa maritima or P. borreri, aud from whom I received 
them on June 29th:—Length generally about three-quarters of 
an inch (though one or two specimens reached nearly an inch), 
and of the usual Crambus shape. Body cylindrical, tapering a 
little at the anal extremity; head narrower than the 2nd segment, 
has the lobes rounded, and is, along with the frontal and small 
anal plate, polished; tubercles large, the front pair on each 
segment rounded, the back pair linear; the skin has a semi- 
transparent glossy appearance. ‘The ground is of a pale dingy 
greyish stone-colour, some specimens tinged with greenish; 
frontal and anal plates of the same colour, but at each side of 
the former, and again immediately below it, is an intensely black 
spot; head pale brown, freckled with darker brown; the mandibles 
very dark sienna-brown, almost black, indeed ; a darker pulsating 
vessel, varying in colour in different specimens from grey to 
greenish, forms the dorsal stripe, but there are no subdorsal or 
spiracular stripes; tubercles of a darker shade of the ground 
colour, and in each is a small black spot, from which springs a 
short black hair. Ventral surface of the colour of the ground of 
the dorsal area; the anterior legs ringed, and the ventral legs 
margined, with dark brown. Lives in a gallery of silk, constructed 
in an upright position on the stem of the food-grass, but close to 
the root, in the same manner as does the larva of C. perlellus. 
The cocoon is about five-eighths of an inch long, a quarter of an 
inch wide, and is firmly constructed. The first moth appeared on 
July 28th, the others at intervals until August 23rd. All were of 
the Lancashire type, and were decidedly larger and broader 
winged than the only specimen of the Deal insect I have, and 
which I presume Mr. Tutt sent me as a representative specimen 
of his cantiellus, The five other specimens in my series, I find
