168 REPORT OF THE COMMISSIONER OF AGRICULTURE. 
The Stenobothri can be distinguished in flight from the former by their much 
smaller size and more slender form and by their more rapid-moving wings. They 
also fly with their body more nearly horizontal than do the various species of Me- 
lanoplus and Camnula pellucida. 
I do not suppose that the flights of this locust as observed to-day are so extended 
nor so frequent as they are with the species which have heretofore been observed 
to migrate. Nevertheless, that there was a true migration in this instance 1 do not 
doubt. It may be argued that their leaving the stubble-field (for such it was where 
this action was first observed) was a necessity, and could have been accomplished 
in no other way. Be that as it may, there were others in the air enough higher to 
have come from considerably beyond the confines of the small field in question. 
Besides, they were seen from other localities later in the afternoon. The wind at 
the time was gentle, possibly 6 to 8 miles an hour. 
My impression is that many more of the Acridide, as well as other members of 
the oruer, are at times migratory. Besides these Stenobothri, Lalso observed during 
August and September a similar movement among the long-winged variety of 
Nemobius bivittatus and Heanthus nigricornis, These latter were leaving a recent- 
ly-mown meadow, wpon which the grass was still green. They also rose to a height 
of several hundreds of feet, and drifted with the wind in a similar manner to that 
employed by the migratory locusts. Nor did they alight immediately after cross- 
ing the intervening meadow, but kept steadily onward as far as the eye could fol- 
low them. Of these crickets at least two dozen, divided about equaily between the 
two species, were noticed on the move. I only remained in the meadow about one 
hour, during which time I was collecting. 
CABBAGE INSECTS. 
Both the Rape and Southern Cabbage butterflies were quite numerous during the 
summer, and their larve did considerable injury to cabbages throughout this por- 
tion of the State. When compared with last year, I think the southern species 
(Pieris oleracea) was present in larger numbers this, while the Rape Butterfly (P. 
rape) was fewer than then. 
I observed oleracea to be more partial to the pepper grasses than to cabbages. It 
also deposited eggs upon various cruciferous plants growing both in the garden and 
about the house. The rape, on the other hand, stuck to the cabbages, kahl, and 
rape, the latter of which grows promiscuously over the fields as weeds throughout 
the country. , 
Besides the larvae of these two butterflies I also observed the small larvae of 
Plutelia cruciferarwn in considerable numbers during the earlier part of the season. 
During August and September but few of them were seen. 
The cabbage-louse, generally called mildew, was also very numerous and caused 
some little damage in a few localities during August and the first week in Septem- 
ber. The same insect also attacked two of my melon vines and a small patch of 
sweet corn, but were soon mastered by the tady-bugs, which flocked in by the 
hundreds. 
THE CODLING MOTH. 
(Carpocapsa pomonella.) 
This insect is becoming so numerous and destructive that comparatively few ap- 
ples escape without a worm or two. In several orchards that I have examined 
during the season the finding of a perfect apple was rather more of a ‘‘ chore” 
than one would suppose might be the case in a new country where apples have 
been raised but three or four years, and that, too, in rather small quantities. 
Hither the moths must migrate in large numbers, or else this Insect also infests 
some native plant. I haveoften found similar larve in both rose-buds and the thorn 
apple. Whether these were those of Carpocapsa or belonged to some other genus 
I do not know, as I have never tried to breed them. [I do not think the increase 
of our Apple moth has occurred entirely at home, for but few apples go to waste, 
even the ‘‘ windfalls ” being utilized in almost all cases. 
FOREST-TREE INSECTS. 
Among the insects that have been more or Jess injurious during the past summer 
the following species were most conspicuous : 
Affecting the Ash, larva of Papilio turnius, Monophadnus barda, Thysano- 
enemis helvolus, and T. fravini. The Papilio larve have been exceedingly numer-
