IN THE BRITISH ISLANDS^ 79 



Zanclognatha, Ld., tarsipennalis, Tr. 



There is very little difference in the tint of the various specimens, 

 but some have the ground colour slightly darker than others. The 

 subterminal line is generally distinct, but the basal and elbowed lines 

 are rather obsolete in some of them. The reniform is only distinct 

 in the better marked specimens. The hind wings also show a central 

 shade in such better marked ones. The pale line parallel to 

 the hind margin of these wings is distinctly marked by a dark inner 

 marginal band in some specimens, although indistinct in others. 



This species was well known to the older entomologists, but was 

 confounded with tarsicrinalis. Thus Hiibner's fig. 5 in the ' Sammlung 

 europ. Schmet.' (Pyralides) is tarsipennalis but he calls it tarsicrinalis. 

 It was also known to the British authors, Ha worth, Stephens and Wood 

 by the same name. Treitschke first detected and differentiated this 

 species from tarsicrinalis, Knoch. He writes : " I invite our entomo- 

 logical friends in Brandenburg to make a closer observation, and should 

 this really prove to be a newly discovered species, I propose to call it 

 tarsipennalis. M. v. Ruhlwein has remarked that the last transverse 

 line varied in different specimens, as it sometimes turned downwards, 

 sometimes it bent more towards the apex and inner margin like 

 Hiibner's figure. Can the formerly described differences in the Iarva3 

 of tarsicrinalis be explained by there being two distinct species ?" 

 Guenee writes of tarsipennalis : "This species, generally confounded 

 with the true tarsicrmalis, is easily distinguished by the very slightly 

 knotted antennas of the male, the more rounded wings, the less clearly 

 marked and less angulated lines, the straighter subterminal, the more 

 imicolorous ground colour of the wings, and the absence of the reddish 

 median shade, the anal brush not divided into divergent tufts," etc. 

 (' Histoire naturelle,' etc. (Deltoi'des), vol. viii., p. 58). 



The only British species that it resembles is barbalis, from which 

 it is abundantly distinct in its browner ground colour and in the 

 direction of the transverse lines, which are, however, almost identical 

 in direction with those of grisealis.

Although Clerck is really the nomenclator of the species it is 

 impossible to look on his figure as representing any particular form 

 of it. The note I made of his figure is as follows : " The figure 

 is very bad, the palpi, shape of the wings and the direction of the 

 transverse lines all indicate that the species is really barbalis as we 

 know it. But the paint has changed colour and is now almost black 

 in all those copies to which I have access. The Linnasan description 

 is also unsatisfactory. Guenee writes : " A description of this species 

 would be useless when it (the species) can be recognised by the 

 characters of which I have spoken in the general notes, viz. the 

 second joint of. the palpi straight and velvety above, the antennae 

 strongly ciliated, and the absence of the areole " (' Histoire naturelle,' 

 etc, (Deltoi'des), vol. viii., p. 56). The Fabrician description from the 

 ' Mantissa,' p. 216 is useless, for he only writes : " Pyralis palpis an- 

 tennis pectinatis brevioribus, femoribus anticis barba porrecta." 



This comparatively large, grey species, which is rather common in 

 most of the woods in the South of England, is readily recognised by
