BRITISH MOTHS. 



of a yellowish green colour, with a slender 

 dark green line in the centre. The sub- dorsal 

 lines are red, edged with yellow. The head is 

 flattened and of a dark reddish brown colour ; 

 the spiracular line greenish yellow ; the belly 

 is greenish yellow, with two darker green sub- 

 ventral lines ; the back and sides are studded 

 with a few very short whitish hairs. Mr. 

 Crewe found this caterpillar feeding somewhat 

 abundantly in August and September, 1862, 

 on the leaves, flowers, and unripe seeds of 

 Gnleopsis tetrahit, and more sparingly on those 

 of G. ladanum. The CHRYSALIS is enclosed in 

 a tightly-spun earthen cocoon ; it is of a 

 yellowish green colour, slightly tinged with 

 red. 



The MOTH appears on the wing in June, and 

 occurs wherever its food-plants are found in 

 England, Scotland, or Ireland. (The scientific 

 name is Emmelesia akhemillata.} 



2-30. The Grass Rivulet (Emmeiesia albulatn}. 



250. THE GRASS RIVULET.- -The antennae 

 are simple in both sexes ; all the wings are 

 pale gray, inclining to white, with numerous 

 transverse waved lines quite white ; the most 

 conspicuous of these are two, close together, 

 just beyond the middle of the fore wings, and 

 a third half-way between these and the hind 

 margin ; the hind wings are almost without 

 markings. 



The CATERPILLAR of this moth has been 

 found by the llev. Hugh A. Stowell. The head 

 is rounded, and narrower than the body ; the 

 body is rather stout, and transversely wrinkled, 

 having a corneous shining plate on the back 

 of the second and thirteenth segments. The 

 head is intensely black and shining ; the body 

 is dingy white, tinged with green, and having 

 a broad medio-dorsal stripe, and a narrower 

 lateral stripe darker green ; each segment has 

 six, eight, or ten minute black dots ; the plates 

 on the second and thirteenth segments are 

 smoke-coloured, and there is a similarly 



coloured corneous plate on the outer side of 

 each of the anal claspers ; the legs and claspers 

 are nearly concolourous with the body, but 

 rather more dusky. It spins together the 

 sepals of the yellow rattle (Rhinanthus Crista- 

 galli}, feeding on the seeds, and is full-fed 

 about the middle of August, when it changes 

 to a CHRYSALIS within the domicile it has 

 already formed. 



The MOTH appears on the wing during the 

 following June, and is very generally distri- 

 buted in England, Scotland, and Ireland. 

 (The scientific name is Emmelesia albulata.} 



251. The Sandy Carpet (Emmelesia decolored*). 



251. THE SANDY CARPET. The antennae are 

 simple iu both sexes ; the fore wings are pale 

 wainscot-brov/n, rather inclining to dull ochre- 

 ous-yellow, and having numerous irregular 

 waved transverse white lines ; the most con- 

 spicuous of these are a pair almost close 

 together across the middle of the wing, but 

 these are interrupted in the middle by two 

 tooth-like projections of the ochreous ground- 

 colour; near the base of the wing are three 

 of these waved white lines, all less conspicu- 

 ous than the median pair ; and half-way 

 between the median pair and the hind margin 

 is a single irregular and indistinct waved white 

 line. The hind wings are dingy white, with 

 few and inconspicuous markings. 



The MOTH appears on the wing in June, and 

 is of general occurrence in England, Scotland, 

 and Ireland, but I have not found it very 

 common. (The scientific name is JEmmeleftiii 

 decelerate.} 



2o2. The Barred Carpet (Emmelesia taniata). 



252. THE BARRED CARPET. The antenna? 

 are simple in both sexes. The fore wings have
