REPORT OF THE STATE ENTOMOLOGIST 1902 115 
leaves, and fewer scales were observed on the portion of the 
tree where the predaceous larvae were most abundant, since the 
scale insects were not clustered along the midribs of the leaves 
where the grubs occurred, as was the case in portions which ap- 
peared to be free froin them. Oct. 17 the cage was again visited, 
and a few living larvae or grubs, together with two or three 
living bectles and a considerable number of pupae, were found. 
Five or six pupae were observed on the wire side of the cage, and 
there was considerable evidence of the larvae having eaten large 
numbers of the scale insects. 
This species resembles our native twice-stabbed ladybug, 
Chilocorus bivulnerus Muls., so closely that only a spec- 
ialist can separate the adults. There is more difference between 
the larvae of the two species, the skin of the imported form being 
reddish or a flesh tint, while that of our native species is dull 
gray. The larval spines of the introduced species are less prom- 
inent and differ structurally from those of our native ladybug. 
There appears to be no reason why our native species should not 
be equally valuable in checking this scale insect, but at present 
at least this introduced form seems to be much more effective, 
and it may prove to be an exceedingly valuable ally in combating 
this most pernicious scale insect. 
Praying mantis, Mantis religiosus Linn. The distribu- 
tion of the eggs of this beneficial species in a number of localities 
in the Hudson and Mohawk river valleys was recorded in our 
preceding report, and the statements of some of the recipients 
that eggs hatched and individuals developed were also published. 
It is worthy of record that the eggs of this species were reported 
by George S. Graves, Newport, as hatching June 22 of the present 
year, and Mr W. C. Hitchcock, Pittstown, states that a nearly 
full grown individual was taken by him Sep. 8, and that several 
others were observed by neighbors. There is a bare possibility 
of a mistake in some of the above records; and yet the appearance 
of this insect is characteristic, and, as each of these gentlemen 
were supplied with figures of the insect, it hardly seems as if 
there could be any doubt of the insect having become established 
in these two localities.
