1870. 93 
In the Verhandl. d. k. k. zool. bot. Gesell. Wien for 1866, Fieber 
figures the genital segment, as seen from behind, showing the position 
and shape of the processes, of no fewer than 68 species of Delphacide ; 
and, since that time, to my knowledge, he has added several others. 
Kirschbaum, in 1868, published a small volume on “ Cicadinen,” but I 
am sorry to say that it is almost incomprehensible. In many instances, 
the colour of the different parts of the insects is not given, and, more- 
over, I believe in a great number of cases that the same insect does 
duty under various names. Of Fieber’s 68 species mentioned above, 
2 are from Sarepta, 1 from Italy, 2 from the Pyrenees, 3 Spain and 
Portugal, 5 south of France, and 2 without any reference as to their 
locality ; the remaining 53 may all be expected to be found in this 
country, in anticipation of which I append the following enumera- 
tion of the major portion of them, trusting that I may thereby excite 
greater enthusiasm in those who have already begun to collect, and 
raise up new workers in the field. Unlike the “ pernicious bloodsucker 
of sleeping man,” they are all warranted inodorous, and may be felt, 
but not smelt. The proper time fer collecting them is between June 
and October, and by sweeping moist or marshy places by far the greatest 
number of species will be obtained. 
The Family DetpHacip® we divide into five genera, viz., Asiraca, 
Delphax, Liburnia, Dicranotropis, and Stiroma. 
Genus 1—AsIRaca. 
Face with two middle keels. Antenne long, first joint foliaceous, transversely 
trigonate, second about one-third the length of the first. Pronotwm with three in- 
distinct keels. Scutellwm with four longitudinal keels. Elytra, basal cell wanting. 
Legs, fore-thighs and tibie broad, foliaceous ; posterior tibize with three spines. 
Genus 2— DELPHaAX. 
Face with one middle keel, scarcely perceptible on the forehead. Antenne 
long, first joint foliaceous, transversely trigonate, second two-thirds the length of 
the first. Scutellwm with three longitudinal keels. Elytra with a short basal cell. 
Legs, fore-thighs and tibize not dilated. 
Genus 83—Lripurnla. 
Crown variously shaped. Face with one middle keel, not distinctly farcate on 
the forehead, except in one or two instances. Antenne not foliaceous, first and 
second joints somewhat cylindrical, first shorter than the second. Scutellum with 
three keels. Hlytra generally only partially developed. Legs simple; hinder tibize 
with one upper and one lower spine.
