270 THE ENTOMOLOGIST. 



Eecord,' vol. xiii, plate 8) they are not transposed, therefore 

 Webb's use of the names transposed is not correct. 



Ab. sericana, Hub. Of this form Webb sa_vs : " Similar to 

 desfontainana, but no central tuft : or if it is present at all it is 

 extremely small." Here, again, Webb falls into an error, into 

 which he was probably led by Desvignes, who writes of this 

 form " the same (as desfontainana) without a button." But 

 Hiibner's fig. 83 has a very distinct orange button, and the 

 ground-colour of tbe superiors is much darker than that of 

 desfuntainana, Fab. Later on I have something further to say 

 anent ab. sericana, Hub. 



Ab. intermediana, Clark. Webb speaks of most of Clark's 

 series as being ab. vittana, and suggests that the varietal name 

 is therefore of little value. Most of Clark's series may have been 

 vittana, though I much doubt this statement, but whether they 

 were or not does not matter one iota : his type agrees with his 

 description, and it certainly is not ab. vittana. The two forms are 

 as distinct as many others, and they are readily distinguishable. 



Ah.Jiavostriana, Webb. This name was given by Webb {loc. 

 cit., vol. xliv, p. 291) to specimens of which he says : " In Bond's 

 cabinet are three, in Clark's one, and I have seen others ; 

 of lightly mottled specimens easily distinguishable from the last 

 ('provittana, Desvgs.) the vitta is distinct and white, tinged along 

 the middle with faintest yellow, head and thorax pale cream. I 

 propose for this variety the above name, which was written on 

 the ticket placed by Bond below the specimens." 



We are here in face of a decided muddle ! It is to be noted 

 Webb does not give the slightest hint of the colour of the superior's 

 disc, or of the button, and for this reason it is quite impossible to 

 grasp what his specimens actually were like, from the description. 

 Turning to the actual specimens in the series I find they are six 

 in number. There are the three Bond specimens, labelled as 

 such by Webb, the one from Clark similarly labelled, and two 

 others, both unlabelled, which one presumes are the " others " 

 mentioned by Webb. Two of the Bond specimens and the two 

 unlabelled ones are of one form, with reddish-brown discs, dark 

 button, and what I should call a cream-coloured vitta, head and 

 thorax. That is to say they had a less yellow vitta, bead and 

 thorax than one finds in the bulk of those known a.s fidvostriana, 

 Desvignes, but otherwise they are not distinguishable from it. 

 The third Bond specimen is of quite another type and does not 

 belong to this group at all, but it resembles a lightly blotched 

 form of ab. scmiustana. Curt., except that the head, thorax and 

 vitta are cream coloured. The Clark specimen has the disc of a 

 dark mouse colour, quite diflt'erent from the other examples in all 

 respects with the exception of the cream vitta, head and thorax. 

 This specimen was placed by Webb, not amongst the others, but. 

 amongst one of his series of ab. fidvostriana, Desvignes !
