ORDER VIII. NEUROPTERA. ole 
thousand eges — for they have been counted — are protruded in twenty-four 
hours. They are instantly taken from her body by the attendants, —a sufli- 
cient number of whom are constantly in waiting in the royal chambers and ad- 
jacent galleries, — and carried to the nurseries, which are sometimes four or 
five feet distant in a straight line. Here, after they are hatched, the young 
are attended and provided with everything necessary until they are able to 
shift for themselves, and take their share in the labors of the community. 
PuryGaNnga. — Réaumur, De Geer, and M. Pictet have thoroughly inves- 
tigated this group, and contributed many interesting particulars to its natu- 
ral history. 
Réaumur classed them as Aquatic Moths. The soft and delicate body of 
the larvex is protected by a case to which it clings by two hooks placed at 
the extremity of the abdomen. “They are called by different names, in 
allusion to their habits; as, for instance, Case Worms, from their living in 
a case covered with little bits of wood or sand, which they draw after them 
as they go. Their scientific name, Phryganea, signifies fagot. The Phry- 
ganex, in the adult state, very much resemble moths. They approach 
them in having rudimentary mouths, and wings without articulations, but 
furnished with small hairs analogous to the scales of Lepidoptera. They 
may be said to form a sort of connection between the Lepidoptera and Neu- 
roptera, 
They have been called Mouches papilionacées, or Papilionaceous Flies. 
The eggs laid by the female Phryganea are enclosed in gelatinous capsules, 
which swell in the water and attach themselves to stones, &c. The larva 
has the appearance of a little worm without feet. It is soon hatched, and 
resembles at first a little black line, and may be easily reared in an aqua- 
rium. The operation of making the silky case which it draws after it, and 
which protects its abdomen, may then be observed. When it is disturbed, 
it retreats entirely within its case. The interior is smooth, and lined with 
mud; on the exterior it is fortified with stones, &c. 
The P. Rhombica furnishes its case with bits of wood or grass. Some 
species arrange these bits of wood and grass in spiral, others in parallel, 
series. Poa 
The P. Flavicornis covers its dwelling with little shells. “These kinds 
of dress,” says Réaumur, “are very pretty, but they are also excessively 
singular. A savage, who, instead of being covered with furs, should be 
covered with muskrats, moles, or other entire animals, would have on an 
extraordinary costume; this is, in some sort, the case of our larve.” Other 
Phryganex employ for constructing the case, which serves them as a dwell- 
ing, sand and small pebbles, each species always employing the same mate- 
rials, unless they are entirely deprived of these, and obliged to employ
