mollis. We enroll on tlie list beautiful and harmless butter- 
flies, witb all their classic names — Priam, Hector, Ulysses, 
Ajax, Apollo, Iris, lo, Achilles, Nestor, Menelaus, Paris, 
Anchises, Helena, Remus, ^neas, Atalanta, and Argus. 
Butterflies are harmless, from the fact that they have 
no mouths to eat with, but simply a proboscis, by which 
they suck the juices of flowers. 
Order 5. Net-winged Insects. — All of the insects of 
this order are useful to man, and deserve our protecting 
care. We mention among the number the dragon-fly 
[Libellula), ever on the wing, hovering over fields, brooks, 
and ponds, greedily devouring gnats, mosquitoes, caterpil- 
lars, and flies of every description ; the horned corydalis 
{Corydalis cornutus), and the day-fly {Ephemera vulgata). 
Order 6. Vein-winged Insects. — These are the busy 
laborers, " gathering honey all the day," and distributing 
the pollen of flowers to render them productive ; or de- 
stroying noxious insects as food for themselves and their 
young ones. 
We notice the gall-wasp {Cynips), which forms the oak 
ball ; the gold wasp {Chrysis) ; the mud-wasp {Spkex Penn- 
sylvanica), which lives in the sand, and destroys spiders 
and cockroaches ; the hornet ( Vesper chartaria) ; the ants 
(Formica) ; and the honey-bee {Apis mellifera). 
Order V. Two-winged Insects, or Flies. — We include 
in this list the various gadflies which annoy horses, oxen, 
and sheep ; the house-fly {Musca domestica) ; the meat- 
fly {Musca vomitoria) ; the Hessian fly {Cecidomyia de- 
structor)', the flea {Pulex irritans)] and the mosquito 
{Culex).
