close inspection, and I think no one in describing such a specimen 
would give its ground color as ferruginous; it would be termed yellow 
or black. The thorax and wing covers being yellow it is evident the 
head with the under side must be ferruginous to render this the pre¬ 
dominant color. 
Finally, when we further take into consideration the facts that this 
is a common species throughout the United States, and that it is a 
pretty insect, which an amateur collector would take special pains to 
secure, it is altogether improbable it would he overlooked and another 
insect be found almost identical with it but so extremely rare that it 
has never been met with in our day. 
In view of all the circumstances, therefore, we think it cannot be 
doubted that this is the insect which Fabricious had in his view. 
We have been induced to state thus fully the grounds on which we 
are led to adopt the Fabrician name for this insect, deeming they 
will settle a subject which would otherwise remain in doubt. From 
this discussion the general reader will perceive how embarrassing it is 
and what an amount of research is often required, to determine the 
legitimate scientific names in natural history. 
As respects remedies for this bug, the probable efficacy of shading 
infested plants and shrubs from the sun has already been mentioned. 
Hand-picking is the only other measure which we have to notice. 
Most of these bugs will elude capture by dropping from the leaves 
and secreting themselves among the vegetation on the surface of the 
ground. But, so timorous and shy as they are, if they are daily 
searched for and routed from their quarters, it is probable they will 
soon forsake the situations in which they find they are so frequently 
disturbed. 
Lilac Measure-worm, Priocycla Armataria , H. Schceffer. (Lepidop- 
tera. Geometridse.) 
In September, eating the leaves of the lilac by night, anil by day hanging from the 
twigs with their heads downward ; a slender humpy ten-footed dark brown worm over 
an inch long, with three bright yellow spots on each side of the hind part of the body ; 
passing the winter in a cocoon under fallen leaves and rubbish, from which the last 
of June comes a pale rusty brown moth, with scalloped wings, an inch and a quarter 
across when oxtended, both pairs having a dark tawny yellow band across their 
middle, and their underside bright orange, crossed by a blackish brown line. 
An interesting insect of our State, a delicate miller or moth, pei- 
taining to the Ennomos group, in the family Geometridte, which had 
escaped observation until our own day, is found on examination to be 
so different from all the species akin to it, that it constitutes the type
