Still more recently Mr. Curtis lias 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:—Scseva Ribesii in No. 4 ; Scale insects in No. 9; 
The Red Spider ( Acarus telarius ) in No. 11; The Snake Millepe¬ 
des ( Julns) in No. 13; Thrips physapus in No. 15; Pear-tree 
Blister Moth ( Tinea Clerckella ) in No. 17; Black and Clay coloured 
Vine Weevils ( Pachygaster sulcatus et picipes) in No. 19; The 
Rocket Tinea ( Cerostoma porrectella ) in No. 21 ; and the Lettuce 
fly ( Anthomyia Lactucce) in No. 23. 
The Heteropterous Genus Phyllomorpha (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 Guerin's Magasin de Zoologie, and 
as the two terminal syllables are formed from the feminine Greek 
word pop<j)rj 9 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 Pliyllomorphus, 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 
* The papers include insects hurtful to animals as well as vegetables.
