no reference that would indicate its occurrence in destructive numbers. 
It ts introduced here as one of a group of insects whose importance will 
I believe be more appreciated when their habits become better known. 
THE RED-BACKED LEAF-HOPPER. 
(Diedrocephala coccinea Forster.) 
So far as I have observed this is not an abundant Species, and while 
evidently common throughout the United States I know of no record 
of its multiplying to numbers sufficient to make it destructive. I have 
found it usually in the vicinity of timber or thickets, and while it prob- 
ably subsists on grasses does not select the open meadows or pastures 
but localities affording more moisture and shade. Itis a handsome and 
conspicuous species, the upper surface when wings are closed being 
largely of a deep red color with dark blue or blue-green stripes. It was 
described under the name of Cicada coccinea by Forster (J. R.), in 1781 
(Novae. Spec. Insect., p. 96), and afterward by Say as Tettigonia quadri- 
vittata. 
THE HIEROGLYPHIC LEAF-HOPPER. 
(Tettigonia hieroglyphica Say.) 
This was quite an abundant species the past season, but the majority 
of the specimens taken were found in the grasses of timber or among 
the low herbage along ravines, grassy banks, ete. 
Professor Uhler says it ‘inhabits Texas, the foot-hills, and plains of 
Colorado from August to October, and the Atlantic region throughout.” 
It is somewnat smaller than the mollipes, usually less than one-fourth of 
an inch in length; the head is rounded in front and marked with irregu- 
lar black crescentic spots and bars. There is much variation in depth 
of coloring and extent of marking so that it is difficult to give a brief 
description that will be distinctive. While it was described in 1831 by 
Say, it has not been so abundant or noted as sufficiently destructive to 
. get a place in the literature of economic entomology. Like many other 
of the species of this family, however, it has been lumped off with 
many of its relatives among the injurious leaf-hoppers, and hence 
should not be regarded as hitherto unmentioned among injurious 
species. 
THE FOUR-POINTED AGALLIA. 
(Agallia quadripunctata Proy.). 
This species appears to be common throughout most of the United 
States, although I am not aware of its having been recorded as occur- 
ring in great abundance at any place. It is, however, one of the species 
which occurs in considerable numbers and does its share toward injur- 
ing the vegetation of pastures and meadows.
