row almost or entirely absent. Bondii is only taken, as far as 

 is known, in England and Greece. 



Chortodes arcuosa, Haw. 



The type of this species is described in Haworth's * Lepi- 

 doptera Britannica,' p. 260, as : — *' alis sordide albo-lutescentibus 

 strigis duabus punctorum minutissimorura fuscornm." " Corpus 

 gracilius fere omnium hujus generis. Costa anticarum punctis 

 ordinariis fuscis, ultimo horum majore juxta apicem. Striga 

 prima recta ante, secunda arcuata pone medium, et inter has 

 strigas in medio sdse punctum solitarium fuscum. Cilia pallida. 

 Posticse ciliaque fuscescentia." There is a great sexual differ- 

 ence, the female having been described by Haworth as a distinct 

 species, under the name of minima {' Lepidoptera Britannica,' 

 p. 216, No. 153), as follows : — " alis rufo-cinereis, maculis duabus 

 ordinariis strigisque tribus pallidioribus " ; " ciliis cinereis. 

 PosticsB fuscse, ciliis albis." There seems to be but little varia- 

 tion in the specimens of the same sex. Of aires, Frr., ii. pi. 162.

Ccenohia, Stphs., rufa, Haw. 



Haworth's rufa (' Lepidoptera Britannica,' p. 260) is the type 

 of this species. Haworth's description is: — "Alis oblougis 

 ciliisque rufis unicoloribus posticis ciliisque pallidis striga medio 

 macularum obscurarum." " Caput inter antennas album." This 

 last phrase is very significant and is clearly shown in some 

 specimens. Geyer, in his supplement to Hiibner's Schmett., 

 gives a good figure of the type (fig. 751) under the name of 

 despecta. This delicate little species is subject to a great deal of 

 variation in ground colour. I took a very long series last summer 

 (1887), and found every gradation in colour, from a very deep 

 reddish, to an exceedingly pale greyish white, the latter being in 

 beautiful condition. There seem to be three distinct forms: — 

 (1) a very red form = the type {rufa) ; (2) a grey form tinged 

 with red = var. lineola, St. ; (3) a pale grey form with no trace 

 of red = var. pallida. 



a. var. lineola, St. — The type of this variety is described as 

 having " the fore-wings shorter than in 7'ifa ; colour, reddish- 

 grey, with a longitudinal brown line at the base, occasionally 

 branching thus •<; a row of dots parallel with the hind margins;
