of breeding in Berlin from dark females was always the 

 typical continental form. 



*' Tmiiocampa gracilis. — The continental form is always 

 much darker than English specimens. 



" Orthosia pistacina. — This common English insect does not 

 occur at Berlin, its place being taken by the smaller and 

 darker nitida. I however took it in large numbers at 

 Leudelange, Luxemburg, last September, and have seen series 

 from other parts of Germany. It varies just as much as it does 

 in England with one notable exception : the bright red forms, 

 which in England form the majority, are entirely wanting. 



" Orthosia litura. — This insect is a reddish insect in England, 

 on the continent it is always a dark blueish-grey, some insects 

 having a tinge of red ; even these forms are however much 

 darker than any I have ever seen in England. 



" On^hodia vaccinii. — This insect is very variable both in 

 England and on the continent. Whereas however the English 

 specimens only seem to vary in the intensity of the red and 

 have a more or less suffusion of yellow markings, the 

 continental vary from red to almost black. The pale English 

 forms with a large amount of yellow markings are absent 

 on the continent. 



" Scojjelosoma sateUltia. — The English forms are generally 

 speaking lighter red than the continental. Dark brown and 

 almost black forms are by no means rare on the continent, 

 though I do not remember seeing such forms in England and 

 if they occur are only aberrations. 



" Xylina seviihrunnea. — Continental specimens are much 

 darker than English. 



*^Xylina ornitlioims. — The ground colour of the English form 

 is almost pure white ; that of the continental grey. I have 

 taken this species at Berlin, Plauen (Saxony), and Leudelange, 

 Luxemburg, always in plenty, but have never taken a specimen 

 in any way approaching the English form (New Forest) for 

 whiteness. 



" As'phaliajiavicornis. — The continental form is much darker 

 than the English ; it more nearly resembles C . or, and is by no 

 means such a handsome insect as the English. The frosted 

 yellowish- green scaling is almost entirely absent.
