101. Tettig'idea $olymorfha Burm.
I have not found this species in the
neighborhood of Moline, but I have a
number of specimens collected by Mr.
Hart in the central part of the State.
102. Diafheromera says' Gray.
This species is not uncommon in Rock
Island county and probably it is not less common throughout the State, though
its form and habits render it too incon- spicuous to be known by many. July
11th is the earliest date I have for its capture at Moline.

A SUPPLEMENTARY NOTE ON DIABROTICA 12-PUNCTATA. BY H. GARMAN, LEXINGTON, KY.
After the first part of my paper on
this insect was published (Psyche, v. 6, p. 29) and the second part was nearly
all in print, I received from Prof. C. V. Riley a copy of his notes on the habits
and life-history of the species with per- mission to use them in what I might
subsequently write. It is not now possi- ble for me to take advantage of this
courtesy further than to add here some
of the more important observations
which his notes contain.

In an introductory paragraph he
says : "Prof. H. Garman justly calls
in question (Psyche, v. 6, p. 29 ; Feb.
1891) a statement made in Insect Life
(v. I, p. 59) where, by a typographical
oversight, the Twelve-spotted Diabro-
tica is stated to have 'bred upon' in-
stead of 'fed upon' melons. The error
is self-evident from the language and
from the tenor of the article which does not treat of larval habits at all but of the food-habits of the beetle."
'My knowledge of the corn-feeding habit
of the larvae of this insect dates from April 30, 1883, when Judge Lawrence Johnson for- warded to me from Allenton, Wilcox Co.,
Ala., a number of larvae of which he wrote as follows: 'I sent you last week from Allen- ton specimens of the same destructive 'bud- worm' that I once mentioned as heard of but not seen. This is about the right time, for they are now going into the pupa stage and in the sand you will find one of the pupae. The worm leaves the corn after doing its mischief and the pupa referred to was found immediately under the stalk among the roots. I have never met with this worm except in the prairie regions of southern Alabama, but have heard of it in Mississippi."'
From these larvae Professor Riley ob-
tained adults May 21, 1883. He ob-
tained larvae and beetles from Missis-
sippi in 1884 where they are said to
abound in corn fields from March to the
middle of May. In June, 1886, they
were reported to him as injuring corn
at Mt. Vernon, Va., the result being a
withering and drooping of the central
parts, while in some cases the plants
were killed as soon as sprouted.
The eggs were obtained by Professor
Riley from females confined with earth,
and were placed in the soil as in the
case of D. longicornis. Larvae col-
lected June 18 from infested corn at
Mt. Vernon, Va., changed to pupae
June 22, and beetles emerged July 6,
and produced eggs on the following
day. Larvae from these eggs were first
observed July 15.
In this connection
Professor Riley continues :
'The above indicates that this insect is at least double-brooded, in which respect it dif- fers in habit from the closely allied D. lo@- cornis which is single-brooded and winters usually in the egg, though occasionally in the adult state. The second brood of Dia- brotica is-functata doubtless winters over, and deposits eggs about the young corn or other plants in the spring. Eggs of the last brood are also doubtless deposited in the fall, and winter over, as is usually the case with D. longicornis."
I am not at present prepared to be-
lieve that the female D. n-&data
produces eggs in the fall of the year.
Careful examination of examples taken
whenever possible has failed to show
ova in the ovaries at any time except
in the early spring just before the first brood of larvae appear, and again when
these larvae become beetles. After
these adults have deposited their eggs,. no gravid females occur again until the
following spring. The search for them
has been especially thorough in the fall and winter, and among all the exam-
ples dissected during these periods not
a single one showed any signs of de-.
veloped ova.
"The early stages of D. is-'punctata are scarcely different from those of D. longi-
