sweet corn being chiefly affected. Examination showed the damage to 
be caused by this insect, and we had some extended observations made 
on its habits by Mr. Pergande, from whose notes the following facts are 
summarized : 
The general aspect of the field was as though it had been attacked by 
Crambus, the central leaf wilting and drooping and the whole plant 
exhibiting a withered appearance. In a great many of the rows not a 
single plant was left, every one having been attacked and destroyed as 
soon as it made its appearance above the ground, and in many cases 
the plant was killed almost as soon as Sprouted. The corn still stand- 
ing was about six inches high and the greater portion of it had been 
recently infested, as was plainly indicated by the withering of the cen- 
tral blades. Examination of these plants almost invariably disclosed the 
larva, sometimes buried for two-thirds of its length, actively at work 
in the heart of the plant immediately above the roots, working In pre- 
cisely the manner of Crambus, of which, however, no specimens could 
be found. 
Two or three of the Diabrotica larve, which are here also known as 
the ‘bud worm,” were occasionally found in a single hill of corn. 
Larve collected June 18 changed to pupxw June 22, and the beetles 
appeared July 6. A number of the beetles were at once placed in a jar 
with earth and corn plants to ascertain the facts regarding their ovi- 
position. On the day following, July 7, large numbers of eggs had been 
placed below the surface of the soil near the plants, in cracks, or 1m- 
mediately about the base of the plants. They were placed either singly 
or In groups of two or twelve, or even more. 
From these eggs larve were subsequently obtained. These, when 
first noted on July 15, were already of considerable size, but were not 
carried to full growth on account of the difficulty of obtaining the plants 
of corn. 
The above indicates that this insect is at least double- prooded in 
which respect it differs from the closely allied D. longicornis, which is 
single-brooded and winters usually in the egg, though occasionally in 
the adult state. 
The second brood of Diabrotica 12-punctata doubtless winters over, 
and deposits eggs about the young corn or other plants in the spring. 
Eggs of the last brood are also perhaps deposited in the fall, and 
winter over, as is usually the case with longicornis. 
Mr. Websievs S experience with this insect in Tensas Parish, en dur- 
ing April, 1887, published in our Annual Report for 1887, is, we hohere. 
the first published record of the corn-feeding habit of is irieece 
No pupe, as stated, were found, but the larve and beetles were col- 
lected and forwarded to the Department in quantity, and the connection 
between the two was unequivocally shown by comparison with the com- 
plete material already in our possession. In addition to these records, 
we have received the larve from Mr. J. M. Thomas of Abbeville, 8. C.,
