THE YOUNG NATURALIST. 



named the more distinct forms as follows, Distinctce, light ground with dark 

 central band ; Fuscalce, smoky ground with dark band ; Cinerce, ash coloured 

 ground with the central band only slightly indicated ; Fuscus, unicolorous 

 dark brown with no band. 



T. Populeti.— This species appears tolerably constant to the type. The 

 most striking of Mr. Gregson' s are three with a row of dark triangular dashes, 

 between the subterminal line and the hind margin. 



T. Mtjnda, v. Immaculata, Staud. Cat., without spots at anal angle. 



T. Crtjda. — A form of this insect that Mr. Gregson calls Irroratce may be 

 described as grey, not reddish, with the surface of the wing distinctly speckl- 

 ed with dark scales. 



Orthosia Suspecta. — A pale grey form of this insect has been called 

 Iners by Treitschke. Mr. Gregson has a dark form, nearly unicolorous which 

 he calls Congener, 



Anchocelis Ktjeina. — A fine and varied series of this species, some with 

 a distinct reddish band across the paler ground colour. A straw coloured 

 form, with the markings dark grey, he calls v. Pallce. 



A. Ltjnosa.— Mr. Gregson distinguishes as v. Luna a reddish form with 

 veins not so distinctly paler as in the type, which is a cold dark brown. 



A. Pistacina. — Fine specimens of all the named forms, which it is not 

 necessary to recapitulate. 



A . Litura, chiefly v. Polluta, Esp., which is larger, and with larger costal 

 spots than the type. 



Cerastis Vaccinii. — -A varied series, including the ferruginous-red 

 form (v. Polita, W.V.), The type varies also, and some are darker and nearly 

 unicolorous, approaching Spadicea. 



Xanthia Cerago. — A good set of v. Flavescens, Esp., with every grada- 

 tion between it and the type. 



X. Adeago, v. Fuscata, Esp., with the centre of the wing reddish orange. 



Cirrhcedia Xerampelina. — A fine set, including two of the dark variety 

 [Unicolor. of Staud. Cat.), and also one nearly all yellow, there only being a 

 trace of the darker central band. 



Dicycla Oo, v. Renago, Haw. In this pretty form the wings are entirely 

 suffused with the darker colour of the markings, except the stigmata and the 

 hind-margins. It is a striking variety. 



Hadena Pisi. — The northern form of this common insect is cold dark 

 brown, the southern form is warmer in tone and redder. A very richly 

 coloured and well marked specimen of the red form is called Spendida by
