39. The Lunar Marbled Brown [Notodonla chaonia}. 



409. THE LUNAR MARULED BROWN. The 

 antenme are pectinated ia the mule, simple in 

 the female ; the fore wings are nearly straight 

 on the costa, blunt at the tip, and have a 

 small tuft-like lobe or angle about the middle 

 of the inner margin ; their colour is pale smoky- 

 black, with three zigzag transverse bars, all of 

 them white A\ith black margins; the first is 

 very short, and very close to the body ; the 

 second is before the middle of the wing, and 

 nearly direct ; the third is beyond the middle 

 of the wing, oblique, and very sharply zigzag ; 

 je area between the first and second bar is 

 niformly smoky ; that between the second 

 d third bars is very pale gray, with a trans- 

 erse smoky cloud, and a narrow crescentic 

 discoidal spot ; the hind marginal area is 

 oky, with an indistinct waved median bar, 

 hich intersects the darker wing-rays ; the 

 inge is alternately gray and smoky ; the 

 ind wings are smoky-gray with darker wiiig- 

 ,ys, and a very indistinct paler median band ; 

 e head and collar are white or gray ; the 

 orax gray ; the body dingy-brown. 

 The lull-grown CATERPILLAR rests in a nearly 

 raight position, and with the anal claspers 

 equently attached to a twig of the food- 

 'lant ; the head is manifestly narrower than 

 the second segment, rather flat and porrected ; 

 the body is slightly attenuated at both ends, 

 and the segmental divisions are very strongly 

 marked, otherwise the caterpillar is uniformly 

 cylindrical ; the anal claspers are long, and 

 are stretched out behind ; the colour of both 

 the head and body is pale sickly-green, some- 

 times approaching to glaucous, and this is 

 the usual colour all over ; but Mr. Hellins 

 informs me that the ventral surface is full 

 green in some specimens : there are four 



narrow yellow stripes, two of them dorsal ; 

 one ou each side dilates slightly at each 

 spiracle, which it encloses : the spiracles are 

 black ; the legs and claspers are unicolorous 

 with the body. It feeds on oak ; but I have 

 not seen a specimen, and therefore have de- 

 scribed the caterpillar from Hiibner's figure. 

 Mr. Greene says of the CHRYSALIS of this 

 species, that it is stouter and smoother than 

 that of N. dodonoea, but not so glossy. 



The MOTH appears in May ; it is a rare 

 species in Great Britain, but seems widely 

 distributed, and Mr. Birchall informs us it has 

 been taken at Killarney, and in the county 

 AVicklow, in Ireland. (The scientific name 

 is Notodonta chaonia.) 



410. The Marbled Brown (Notodonta dodoitasa). 



410. THE MARBLED BROWN. The antennae 

 are pectinated in the male, simple in the 

 female ; the fore wings are nearly straight on 

 the costa, blunt at the tip, and have a small 

 tuft-like lobe or angle about the middle of the 

 inner margin ; their colour is smoky and 

 marbled-gray at the base, intersected by a 

 curved paler transverse line, which descending 

 from the costa, terminates in the inner- 

 marginal lobe : this smoky area is followed by 

 a broad pale-gray almost white band, and the 

 hind-marginal area is of nearly the same colour 

 as the basal area, but generally more marbled 

 and varied ; there is no discoidal spot ; the 

 fringe is alternately gray and smoky ; the 

 hind wings are pale smoky with darker wing- 

 rays, and an indistinct transverse paler band : 

 the head, collar, and sides of the thorax are 

 very pale gray, sometimes quite white ; the 

 hind part of the thorax is smoky, varied with 

 gray ; the body is fawn-coloured. 



The head of the CATERPILLAR is broader than 

 the second, third, or fourth segments ; its 

 colour is bluish-green and reticulated ; the
