beetle larvae. Gallida decora is an exceedingly common species in parts 
of the South, and both larvaB and adults destroy the Cotton Worms. The 
larva? of this beetle, upon one occasion, according to Mr. Hubbard, were 
sufficiently numerous to cause a marked decrease in the number of the 
worms in certain parts of the field (at Orescent City, Fla ). They cap- 
tured the young larvae upon the leaves in great quantities, and even 
successfully attacked grown worms many times their own size and 
weight. The imago of the beetle not only destroys full-grown worms, 
but was found eating the chrysalides. 
A number of different Lady-birds (Coccinellidce) are constantly found 
upon cotton, and their larvae have occasionally been observed to eat the 
eggs of Aletia. These larvae have also been found to destroy large chrys- 
alides of other moths while yet soft after the transformation, biting large 
holes in them and suckiug the juices, and will un- 
doubtedly be found to destroy Aletia pupae in the 
same way. The small, obscure beetles with floccu- 
lent or cottony larvae, belonging to the geuus Scym- 
nas, are especially abundant, but they have never

Soldier-beetles (TelcpJioridcv) and "Fire-flies" (Lampyridce) are also 
quite common on cotton. The beetles are pollinivorous, while the larvae 
are predaceous, and in several instances have been known to destroy 
Aletia. Two full-grown larvae, which 
we recognize as those of Chaulio- 
gnathus americamts, were found by 
Mr. Hubbard feeding upon Cotton 
Worm chrysalides on the leaves.

We have also observed, as has also Mr.Patton, the same species feed- 
ing upon pupae of Aletia in Alabama. In addition to what we have 
published on the habits and transformations of this beetle (Mo. Ent. 
Reports, I, p. 57, and IV, p. 28), the following notes by Mr. Hubbard on 
its earlier life-history are interesting: 
The eggs of Chauliognathus pcnst/lvanicus, which you gave me at Savannah, August 
4 (my No. 68), hatched during the night of August 9. On August 10 I mouuted 
twelve of the larva in balsam (Slide No. 62). I succeeded in feeding them on young 
aphids from cotton, the bodies of which I crushed. They were very timid, and ate 
sparingly. The color is silver gray, almost white. August 12 the larva? retreated to 
bottom of earth in the bottle, and curled up in clusters. In two or three hours (10.45 
a.m.) they had moulted. Their color now changed to a lead color, or mouse color. 
Immediately after moulting they became very active, climbing all over the sides <>t" 
the jar. I gave them crushed l'hora ah tier, and they sacked the juice readily. They 
attacked the uninjured maggots, but were unable to pierce the skin. I preserved 
several in Wickershei in solut ion (Xo. 02, B). I gave them, August 15, a species of large, 
red Aphis, found on cockle-burr, but they did not relish them, and ate but little. They
