terminal line pale, edged internally with blackish ; the nervures 

 distinct on the outer margin. The hind wings dark grey, with the 

 base paler and lunule distinct " (' Sammlung europaischer Schmet .,' 

 fig. 171). 



8. var. junctus, Haw. This is the sub- variety of the type, in which 

 the reniform and orbicular are united. It is described by Haworth as 

 follows: " Bombyx. Alis griseo-ferrugineis, annulis duobus con- 

 fluentibus strigaque postica pallidis." " Praecedenti (cerasus) simillima 

 et fere eadem sed paulo minor. Antennae minus pectinatae. Dignosci- 

 tur primo intuitu stigmatibus junctis nee liberis seu distantiusculis, 

 unde nomen ; caeteris praecedente omnino convenit. OBS. Nunquam 

 ullo modo variat " (' Lepidoptera Britannica,' p. 123). This form of 

 variation is so frequent in all the different varieties, that it is hardly 

 worthy of special notice. 



c. var. rufa, mihi. The anterior wings of this variety are of a 

 bright red coloration, with a considerable amount of variation in the 

 colour of the outlines of the stigmata and the transverse lines ; so much 

 so, that the wings are frequently unicolorous, at other times, they have 

 distinct pale outlines to the stigmata and pale transverse lines. In 

 this variety the subterminal is sometimes very pale and white, 

 but the dark central band is rarely strongly developed. My specimens 

 have come from Hereford, Romsey, Nottingham, Morpeth, Sligo, 

 Forres and Chattenden. 



. var. rufannulata, Haw. This dark reddish form of stabilis has 

 not always a red, or even ochreous circumscription to the orbicular 

 and reniform, and it is useless to keep the name for such an unstable 

 character. As, however, Haworth's name comprises the reddish- 

 fuscous forms, I have retained his name for all such dark reddish 

 varieties. Haworth's description is : " Noctua. Alis rufo-fuscis 

 striga postica rufa extus pallida, stigmatibus liberis rufo-marginatis." 

 "Prsecedenti (flavilined) valde affinis,atdiffertnotabiliterut in charactere 

 specifico. Alse posticse prsecipue in mare, nigricantes, ciliis f uscis ; 

 nee runs ut in ilia. Caeteri simillima. Sequenti differt stigmatibus 

 liberis nee junctis, antennis masculinis longioribus, magisque pectinatis " 

 (' Lepidoptera Britannica,' p. 243). 



Tceniocampa, Gn., pulverulenta, Esp. 



This little species (with miniosa) exhibits less variation than the 

 other species of Tceniocampa. The ground colour exhibits none of the 

 extreme range found in instabilis and opima, nor do the markings 

 show any extreme forms as in gothica. The colour varies from a 

 whitish-grey to red, but all the specimens are of one of these colours 

 or a mixture of them: The transverse lines are generally ill-developed, 

 consisting of dots, but occasionally the dots become united into distinct, 

 wavy, black lines. The stigmata vary very much, the orbicular some- 

 times being obsolete, sometimes a pale ring, sometimes filled in with 

 dark; the reniform is generally distinct, but varies in shade from 

 being of the ground colour surrounded by a pale ring, to the whole 

 being filled in with dark fuscous ; its lower part is generally dark. 

 The subterminal line is generally obsolete, or, if present, pale in colour. 

 Between the subterminal and outer margin, there are frequently pale 

 patches between the nervures, giving the same mottled appearance 

 noticeable in many specimens of gothica. Humphrey and Westwood 

 wr ite : " Varieties occur, in which the ordinary strigas are rather
