NocTua. — Haworthi , Curtis. There is a specimen in the Linnean Cabinet, 
marked “ Angl., D. Jones, unknown.”— Prcecox , in Linnean Cabinet, marked 
“Portland Island, Allen.”— Citrina? in Linnean Cabinet, marked “ Noctua 
mucronea , B. Clark: Suff., Kirby, 1797; rariss.”— Siona dealbata , near 
Langport, June, 1835; Mr. Quekett.— Arcturus: Mr. Westwood says that 
Mr. Curtis’s genus Arcturus must be rejected , having been previously used by 
Latreille, to distinguish a genus of Crustacea . (Perhaps Latreille’s genus Arc¬ 
turus may fall also, being used in Astronomy ; and Stephens’s Janus has been 
used by Kirby and Spence). But what will be gained by its being changed ? 
Can a Moth ever be confounded with a Crab ? The name Colias , a genus of 
Butterflies , was previously used for a genus of Fishes , I believe, and yet it is con¬ 
tinued by all ; and perhaps neither may stand eventually, by the perpetual chang¬ 
ing of systems. Agabus is used for a genus of Water Beetles, but its proper sig¬ 
nification is a Locust ! ! 
Again; Mr. Curtis is said to have placed Acentria at col. 137 of his Guide , 
at the end of Trichoptera. Mr. Curtis not being sure that Acentropus was iden¬ 
tical, of course gave another name, similar however, and, in the Guide , places it 
just before Lepidoptera, one of which Mr. Westwood considers it. Mr. Curtis’s 
arguments have more weight with me that it is Trichopterous ; and they both 
agree that Stephens is wrong in putting it in the Neuroptera. 
Moses Harris, in his Vade Mecum , mentions his having seen an Algeria on 
a flower, in Norwood. Algeria ichneumoniformis I found an hermaphrodite 
specimen of, near Lulworth, on the 6th of July last; August 5th and 11th, I 
found several at Carisbroke Castle, varying much in size. The small variety is 
figured by Mr. Wood as a new species, and named Muscaformis. Mr. Rudd took 
a very large and magnificent specimen on the 11th, which shews it was not too late, 
although several were much faded; I also took one near Niton, on the 8th. The 
late Captain Blomer observed that they vary in size, and he found them in plenty 
near Teignmouth, settled on rocks from June 29 to the end of July. Some I 
observed were fond of the Ononis: they seemed partial to the neighbourhood of 
the sea. Algeria vespiformis, (Curtis), I took in plenty, the end of May and 
beginning of June, in Clapham Park Woods, Bedfordshire: the first I saw was 
on a leaf of burdock; but I afterwards found the larvae and pupae under the bark 
of the stumps of oaks, and found them in every stage at the same time. Mr. 
Rudd took one in the New Forest the end of May, 1834; and I saw one the 
beginning of August, 1835, hovering over an oak stump there, but lost it; a cloud 
passing over the sun at the same time. Hypogymna dispar , found on the Turf 
Moor, near Shapwick, Somerset. In the Linnean Cabinet I observed a Moth 
allied to the genus Spilosoma , or Arctia . Whitish, or speckled slightly with 
black, and rather transparent, from Mr. Hudson ; but it is not noticed as British 
in any book I have seen: the antennae are too much pectinated for it to belong to
