82 VARIETIES OF 



among specimens of the normal form in the Upper Hartz Mountains " 

 (' Stett. ent. Zeit.,' 1884, p. 363). 



Hadena, Och., peregrina, Tr. 



This species, which is known as a British species from the two 

 specimens captured in the Isle of Wight, is common on the shores of 

 the Mediterranean. Treitschke's diagnosis of the species is : 

 " Hadena alis anticis argillaceis, macula conica obscuriori, striga 

 postica dentata albida, maculis sagittiformibus brunneis ; posticis 

 albis fusco venosis " (< Die Schmet.' &c., iii. p. 330). Treitschke 

 then continues : " In size, form and markings, this conies near dentina. 

 In colouring, however, it is quite different, and the ground colour is 

 of a whitish brown, and might perhaps be compared with certain 

 specimens of Agrotis cursoria. The head, thorax and collar are quite 

 plain, the body somewhat lighter above with fine tufts on the sides. 

 On the extremity of the body of the males is a yellowish-brown 

 intermixed tuft. Antennae like those of dentina whitish-yellow. On 

 the fore- wings not a trace of the first basal line is visible, but, to the 

 second basal line, which is whitish bordered with dark brown, is attached 

 a hollow claviform. Over the orbicular, which, like the reiiiform, 

 has a whitish centre with a brown border, runs a light costal streak, 

 as in dentina, but it is not pectinated and joins the band. The angu- 

 lated line consists of fine brown lunular marks (edged with white), 

 and the dentate subterminal line is of the same colour. Between 

 these lies a mottled space, with particularly handsome markings. 

 On each nervure, is seen a cuneiform mark, and before the points, 

 which are turned towards the base, is a white dot. The subterminal 

 line has two projections turned towards the fringe. The fringes are 

 bordered by a row of dark brown dots and a white line and are 

 interspersed with light and dark brown. The hind wings are pale white 

 sprinkled with brown along the nervures ; the brown scales form a 

 slight band towards the white fringes " (' Die Schmet.' &c., vol. v., pt. vi., 

 p. 330). Of Hadena peregrina, Tr., Mr. Stainton writes : " Not very 

 closely allied to any of our known species. In September, 1857, 

 Mr. Bond took a specimen at Freshwater, in the Isle of Wight ; the 

 insect is a native of Southern Europe and attached to low coasts " 

 (' Ent. Ann.' 1859, p. 147). A second specimen was afterwards 

 captured in the same locality. 



Hadena, Och., trifolii, Rott. (chenopodii, Fab.). 



There is no type description of this species, but it was named by 

 Rottemburg on Rosel's figure, vol. I., PI. 48. Of this Rottemburg 

 says : " Not very well figured and does not altogether agree with the 

 moths I have bred from the larva figured " (' Der Naturforscher,' ix., 

 131). This species varies but little in Britain and then only in the 

 shade of the ground colour, which is usually of a somewhat pale ashy- 

 grey. Occasionally, specimens are brownish-ochreous and appear 

 more unicolorous, but such varieties are not at all frequently met with. 

 The diagnosis of Fabricius is : " Noctua cristata alis planis cinereis 

 nigro maculatis: striga postica bidentata alba, thoracis crista brevi 

 bifida." " Alse anticee cinerese atomis in primis costse marginisque 

 postici nigris. In medio maculae ordinarire. Ante marginem posticum
