seeds. When small these larva are whitish, gradually becoming a dull 

 pink when full fed, I have only found them in one long straggling 

 locality, but in that one place have seen them at times swarming on 

 every plant. The sea buckthorn f Hippophce rhamnoides) a shrub that 

 on this broken ground near the sea shore cannot fail to attract our 

 attention at this time, for the terminal shoots are twisted and distorted 

 by the larva of Gel. hippophaella, these larva are pale yellowish green 

 with black spots and and head brown, very local, not always to be 

 seen where the food plant is growing. The sea spurge (Euphorbia 

 pamlias ) which is generall to be found where the sea buckthorn is grow- 

 ing, must at this time be examined, for some of the tops will appear 

 brownish and drooping, this is caused by the larva of 5. euphorhiana 

 which feed inside the top of the stem. In the tops of the rest harrow 

 the larva of P. phcedactyUis may be taken commonly at the beginning 

 of the month. The flowers of the ox eye daisy (Chrysanthemum 

 leucanthemuin) should be examined now for they are out at the full, 

 when some will be observed having a few of the florets drawn over 

 and fastened down with silk, these should be collected for they contain 

 larva of a few species of Sciaphila, two of which, viz. : pasivana and 

 shmana I have repeatedly bred many specimens. In places where 

 Glyphipteryx fischeriella occurs the seed heads of the cocks foot grass 

 (Dactylus glomerata ) should be gathered, from which a beautiful series 

 of the insect may be bred.

THE GENUS ACRONYCTA, AUCT. 



As I am wholly responsible for the citations in Mr. Butler's paper, 

 which Mr. Lewcock complains of (pp. 133-134), I. should like to say 

 a few words in explanation, 



(i.) It is an established rule in nomenclature that when a new 

 name comes into use, the person who first proposes that name in a 

 recognized publication is to be cited as its author. Zoologists, as a 

 rule, cite only the author of the specific name ; while Botanists usually 

 cite the author of the binomial. To be precise, it is necessary to cite 

 both, the first within brackets, unless, of course, the species was first 

 described under the same generic name as is now used for it, when 

 the author of the species and of the binomial are the same.
