BRITISH AXD EVROrEAN BUTTERFLIES AXD MOTHS. 



the males are setiform, shortl}' ciliated. The 

 fore wings are obtuse at the tips. The only 

 species is: — 



T. atriplicis, Linn. The Orache Aloth. 

 Plate XXV. fig. ii. Larva iia. This moth 

 is common in Central and Southern Europe 

 in June and July. The larva is green when 

 young, reddish brown when mature, marbled 

 with darker and with a dark dorsal line, a 

 pale grey double lateral stripe and two yellow 

 spots above the anus. It feeds from July to 

 October on AiripUx, Polygonum, etc. On the 

 Continent it appears in large numbers in some 

 years, wandering about in companies which 

 sometimes number hundreds of thousands, but 

 in England it is very' local and rarely abundant. 



Genus Trigonophora, Hiibn. 



This is distinguished from the Genus Hadena 

 b}' the fore wings being dentated and the 

 thorax not crested. The antennas are dentated 

 and ciliated in the males. 



T. flammea, Esp. The Flame Brocade. 

 Fore wings violet-brown, with darker patches 

 near the base below the stigmata and on each 

 side of the reniform stigma. Tliis is conspi- 

 cuous, pale yellowish, with a wedge-shaped 

 dash passing from its lower end towards the 

 base. There is a narrow whitish streak on 

 the inner margin. The hind wings are smoky 

 brown, paler at the base, and have a dark 

 crescent-shaped central spot. It is found in 

 Western Europe in September and October. 

 The larva is greyish brown or greyish green, 

 with three pale lines and a row of darker 

 lozenge-shaped spots on the back. It feeds on 

 low plants from Februarj- to Ma}-. 



Genus Euplexia, Steph. 



Thorax broad, very strongly arched, hairy, 

 intermingled with fiat scales, smooth over the 

 whole of the back, with two prominences at 

 the extremity which extend far beyond the 

 end of the thorax. The abdomen is some- 

 what short and slender with tufts on the third, 

 fourth, and fifth segments, that on the third 

 being especially large and prominent. The 

 antennae are setiform and shortly ciliated in 

 the males. The anal fold is long and slender, 

 in curved and strongly concave on the under 

 side. The only species is: — 



E. lucipara, Linn. The Small Angle- 

 Shades. Fore wings bright walnut-brown, 

 nearly black in the central area, with two 

 double black transverse lines, a few small 

 black spots in the basal area, and imperfectly 

 black-edged stigmata. The orbicular stigma 

 is large, and indistinct on account of its dark- 

 ness, the reniform is straight and yellowish 

 white, with a brownish nucleus near its extre- 

 mity. The submarginal line is yellowish and 

 indistinct, darkly suffused on the inner side 

 and marked with black, especially in cells 6 

 and 7. The space between this and the 

 slightly black -spotted marginal line is suf- 

 fused with purple like the costa. The fringes 

 are dark with curved bands which are yellow 

 at their extreme base. The hind wings are 

 greyish yellow, darker towards the hind mar- 

 gin, with an indistinct curved line expanded 

 on nervure 2 into a small black spot, and a 

 pale zigzag line near the hind margin opposite 

 the anal angle. The fringes are yellow at 

 their base, and white at the extremity, the 

 remainder from the front to the anal angle 

 being dark brown. The head and thorax are 

 blackish brown marbled with yellow, and the 

 abdomen brownish-grey with tufts of hair on 

 the back. The moth is common in Central 

 and Northern Europe from May to July. The 

 larva is grass green or brown, with the sides 

 and incisions lighter, with a whitish yellow 

 line below the dark brown spiracles and two 

 connected oblique streaks on the back of each 

 segment. It lives on bramble, raspberry and 

 other low plants in August and September. 



Genus Habryntis, Led. 



The fore wings are triangular, with the 

 apices produced. The thorax, legs, front and 

 palpi are clothed with fine smooth hair. The 

 palpi are curved upwards and form with the 

 hair of the front a short, obtuse snout. The 

 collar is excavated. The thorax behind the 

 collar has a sharp crest which is produced in 

 a sharp longitudinal ridge, and rises into a 

 saddle-shaped projection behind, terminating 

 in a truncated prominence. The abdomen is 

 slender and not tufted. The proboscis is 

 spiral and the eyes are naked. The antennas 

 are setiform, very short in the males and 

 closely ciliated. The anal fold is slender and
