t \vecn this scries of markings and the legs is a 

 lender white line on the anterior segments, 

 id attached to each of the markings is a 

 utll white spot ; the ventral area is smoke- 

 )loured tinged with green, and the legs and 

 laspers are of the same colour. When 

 rived at its full size, it finally leaves its 

 silken home and builds another, in which it 

 changes to a smooth CHRYSALIS, which is of a 

 estaceous red colour, the wing-cases being 

 especially red ; it is covered with a slight 

 whitish bloom, like that of a ripe plum ; the 

 last segment is fluted, and terminates in three 

 spines, the outer ones of which are smaller 

 than the middle one. 



The MOTH appears on the wing in July, 

 August, and September ; there seems to be a 

 continuous succession of moths for about ten 

 weeks: it is very common in most of our 

 English counties, and occurs also in Scotland 

 and Ireland. (The scientific name is Bryo- 

 fj ft tin Per la.} 



423. The Tree-lichen Beauty (Bryophila Alga). 



423. THE TREE-LICHEN BEAUTY. The an- 

 tenna) are slender, simple, and alike in both 

 2xes. The fore wings are rather ample, 

 sarly straight on the costu, and rounded at 

 le tip ; their colour at the base is gray-green, 

 followed by a nearly straight transverse bar 

 almost white ; then follows a broad median 

 brown band, which includes a darker dis- 

 coidal spot ; then follow a very pale bar very 

 distinct, and divided at both extremities, but 

 less distinct in the middle, and lastly, a 

 grayish or brownish green hind margin : the 

 hind wings are brown, with a perceptible but 

 not very conspicuous crescentic discoidal spot : 

 the head and thorax are brownish green, the 

 body paler, with a medio-dorsal series of 

 black spots. 



The CATERPILLAR is gray-green, marbled, 

 with a white mcdio-dorsal stripe, and a series 

 of white lateral spots ; a stripe near the 



spiracle, and a horse- shoe shaped marking are 

 black ; the head also is black : it feeds on the 

 lichens which grow on trees. I am un- 

 acquainted with this caterpillar, and have 

 made the best I can of Guenee's brief descrip- 

 tion. 



The MOTH appears on the wing in July : two 

 specimens have been taken by Mr. Sidebotham 

 in the north of England, but I have neither 

 seen these nor any other British examples. 

 (The scientific name is Bryophila Alt/oe.} 



424. The Scarce Marveil-du-Jour (Diphthera Orion}. 



424. THE SCARCE MARVEIL-DU-JOUR. The 

 antennae are ciliated in the male, simple in 

 the female ; the colour of the fore wings is a 

 beautiful clear green, with four longitudinal 

 white stripes, and three interrupted transverse 

 black bars; the four white stripes are equi- 

 distant, the first costal and narrow, the 

 fourth inner marginal and narrow, the inter- 

 mediate ones rather broader ; the first black 

 bar is near the base of the wing, much bent 

 and very irregular ; the second is median and 

 interrupted in the middle ; the third is the 

 broadest and most conspicuous, very much 

 bent and slightly interrupted, it is accom- 

 panied on the outside by a smoky-band ; the 

 orbicular spot is small, and is united with the 

 median bar on its inner side ; the reniform 

 spot is outside the median bar, it is black 

 with a white exterior border ; there is a 

 regular hind-marginal series of black and 

 white spots, the inner portion of each being 

 white, the outer portion black; the fringe is
