Still more recently Mr. Curtis has commenced the publication of 
a similar series in Dr. Lindley’s weekly newspaper, the Gardener’s 
Chronicle. The articles which have hitherto appeared are the 
the following:—Sczeva Ribesii in No.4; Scale insects in No. 9; 
The Red Spider (Acarus telarius) in No. 11; The Snake Millepe- 
des (Julus) in No. 13; Thrips physapus in No. 15; Pear-tree 
Blister Moth (Tinea Clerckhella) in No. 17; Black and Clay coloured 
Vine Weevils (Pachygaster sulcatus et picipes) i No. 19; The 
Rocket Tinea (Cerostoma porrectella) in No. 21; and the Lettuce 
fly (Anthomyia Lactuce) in No. 23. 
Tue Hereroprerovs Genus Puytromorpua (illustrated in plate 
2) offers an instance of the want of uniformity in the principles 
which regulate the modern generic nomenclature of insects, and 
which it is to be regretted are not more universally recognised 
amongst naturalists in general. The genus was proposed, with the 
name which I have adopted, in Guérin’s Magasin de Zoologie, and 
as the two terminal syllables are formed from the feminine Greek 
word opi), the feminine Latin termination was given to the word 
Phyllomorpha. Dr. Burmeister, however, adopting the principle 
that the generic names in each family should follow the sex of the 
primitive, or typical genus, altered the name to Phyllomorphus, to 
accord with the sex of the name of the typical genus, Coreus. Still 
more recently M. Rambur, (in his work on the Entomology of 
Andalusia,) on the principle that no name which had been used - 
specifically should afterwards be given to the genus in which that 
species so named was introduced (a new specific name being in such 
case required for the species in question), has altered the name
