76 LEPIDOPTERA. 



concerned only as jet found in Perthshire. This is strange, 

 because the type occurs in Central Germany and in Switzer- 

 land. The Alpine var. Gruneri is a larger greyer insect. 

 Our author asks, if this is the Scottish form? 



Pachnobia Alpina. — Pachnobia is a genus founded by 

 Guenee, and Dr. Stau dinger places four insects in it, two of 

 which are our TcBniocampa rubricosa and T. leucographa. 

 The fourth, No. 1608, Pachnobia Carnea, an insect of 

 Lapland and Labrador, w^as long thought by me, from a pro- 

 bable though careless mistake, to be the Scottish moth; this 

 is not the case however — our Perthshire Noctua is Agrotis 

 liyperborea, var. Carnica, No. 1098 in the Catalogue : the 

 type is a northern and Alpine insect, distributed rather 

 widely in Europe. There is an evident confusion about the 

 genus Pachnobia ; in the "Manual," " forewings with very 

 distinct lines and spots," is given as a generic character; now 

 this can scarcely be said either of rubricosa or leuco- 

 grapha. What insect does Guenee assign as a type ? 



Asteroscopus Nubeculosus. — Here again we have a rather 

 widely distributed European species, confined, as far as our 

 islands are concerned, to Rannoch. A few words must here 

 be said about the position of this insect as well as that of 

 Demas Coryli and Diloba CcBruleocephala in our author's 

 list: he regards all of them as belonging to the A^oc^w^. On 

 this subject he makes himself some excellent remarks in the 

 Entom. Mo. Mag. for March, 1871, showing that the egg 

 of both Diloba and Asteroscopus favours this position. This 

 is a physiological fact of some importance, much more so 

 than the possession of stigmata; these are more or less 

 marked in many Bombycidce, as in Dasychira pudibunda, 

 Bombyx lanestris, B. Trifolii, B. Quercus^ &c. ; and even 

 in the Pseudo-bombycidcB, as in Notodonta trepida and N. 

 Dromedarius. Again, though well marked in some species of
