ol4 VARIETIES. 



fourteen abdominal legs, which I found in great abundance on 

 poplar- trees, produced Nematus dhnidiatvs (see pi. 1. fig. 1). 

 On the Scropliularia aqnatica^ in my garden, I obtained num- 

 bers of the larvae of Allantus scrophnlaricB : it is remarkable 

 for its great change of colour in its last skin ; from having been 

 a clear blueish-white, with several rows of jet black spots, it 

 becomes a dirty brown colour (see pi, 1. fig. 2 and 3). The 

 green larva represented, is that of Crcesus Sejjteutrionalis, a 

 description of which you will receive from its captor. The 

 accompanying plate is engraved by my friend, Mr. Ingall, and 

 coloured by a gentleman who does not wish his name made 

 public, and most exactly represents the insects above named.

 our part to make our Magazine a worthy receptable of such

 and adjectives. I do not think even Mr. Curtis's name of suffi- 

 cient weight to authorize an innovation, which it was certainly 

 the duty of an editor to have guarded against.

[We certainly regret that these very unscientific appellations 

 should have escaped Mr. Curtis's notice in the revision of the 

 proofs ; for our own part we feel a delicacy in making altera- 

 tions, which might not, by our contributors, be deemed justi- 

 fiable : our reader will perceive at once that our correspondent 

 must refer to Silo, CIdamydatus, Loricula, and Galeatus. 

 We select Delta's observation on this subject as the most tem- 

 perate one of four, and because we are sure it is written with 

 no unfriendly feeling either towards ourselves or Mr. Cui'tis.
