BRITISH MOTHS.

396. The Dusky-marbled Brown (Gluphisia crenata). 



396. THE DUSKY-MARBLED BROWN. The an- 

 tennae of the male are strongly pectinated, those 

 of the female slightly so ; there is no tuft of 

 scales at their base, the fore wings are blunt at 

 the tip, the hind margin almost straight, the 

 inner margin has no angle or tuft, their colour 

 is dingy-brown with a gray transverse line ac- 

 companied exteriorly by a dark line before 

 the middle ; beyond the middle is a similar 

 gray line with a similar accompaniment, but 

 conspicuous only on the inner margin ; beyond 

 and parallel Avith the hind margin is a pale 

 zigzag bar very imperfectly developed : the 

 hind wings arc dingy-brown ; the head, thorax, 

 and body are dingy-bi'own. 



"The CATERPILLAR is pale green, the dors:il 

 line spotted with ferruginous; bordered on 

 each side by a yellow line. (Dup.] On poplar."

The MOTH appears on the wing in June. 

 Three specimens have been taken at Epping, 

 and I believe nowhere else in Great Britain.

simple in the female ; the fore wings have the 

 costal margin straight, the tip scarcely pointed, 

 and the hind margin slightly scalloped ; they 

 are semi-transparent and of a pale raw sienna 

 brown, with a much-bent interrupted and very 

 indistinct paler transverse bar beyond the 

 middle ; the wing-rays are brown, except 

 when they cross the pale bar : the hind wings 

 are rather paler than the fore wings, but the 

 head, thorax, and body are of the same colour 

 as the fore wings. 



I am indebted to the Rev. H. Harpur Crewo 

 for the following information : 



The EGGS are brown, and laid in the month 

 of November. 



The CATERPILLAR is pale whitish, green, the 

 centre of the back is bluish, the sub-dorsal lines 

 are distinct and white ; the spiracular lines 

 pale yellow, slender and waved, two on each 

 side, the lower of each pair becoming broader 

 on the anterior and posterior segments ; the 

 segmental divisions are pale yellow, the ventral 

 area is grass-green. It feeds on maple (Acer 

 campestris] in shady woods and hedges, gene- 

 rally in chalky districts, and is full-fed at the 

 end of June and beginning of July. 



The CHRYSALIS is enclosed in a tight earthern 

 cocoon, rather short and black ; rich dark red- 

 dish-brown ; its thorax and wing-cases are 

 almost black. The extremity of the body is 

 furnished with a bristly bifurcate appendage. 



The MOTH appears on the wing in October, 

 and seems to be of very rare occurrence in this 

 country. My specimens are from Buckingham- 

 shire, but I do not know the exact locality.

 tenna) are beautifully plumose in the male,

 tip ; the antennas are strongly pectinated in
