D. pulicarius, Fieb., Syn. Eur. Delt., 11, 27, fig. 27. 
Oblong-ovate ; upper side pale brown, under side and legs black, 
knees and front tibie brownish yellow. Crown in the male as long 
as, in the female shorter than, its basal width, twice as long in the 
middle as at the sides, free sides strongly arcuate, angle very 
blunt; brownish yellow, variously spotted with fuscous or black, or 
entirely brownish yellow; in well-marked examples the basal 
markings are present, the interocular line is represented by a pair 
of black spots on the disc, the interocellar line by two or four 
black spots, and the infraocellar line is biarcuate. Frons black, 
with or without a few brownish yellow transverse lines. Pronotum 
one-third or more shorter than the crown, frequently blackish on 
the hinder half. Elytra about two-thirds as long as the abdomen, 
widely rounded behind, apical areas extremely short, supra- 
brachial area and those adjoining filled up or at least margined 
with fuscous; not unfrequently the costa is dark fuscous, and all 
the areas except the costal are filled up with that colour; nerves 
pale, the transverse ones white. g; abdomen black, hind margin 
of the genital valve white, genital plates about three times as long 
as the valve, their outer margin slightly sinuate just before the 
apex. 93 abdomen black, hind margin of the last dorsal segment 
white, hind margin of the last ventral segment forming three 
rounded lobes, of which the middle one is less than half as large 
as either of the others. Length, 2—2} mm. 
Very common amongst grasses in damp places.

Fieber, Cicad. d’Kur., part 1., 128 (1876). 
Body oblong, widest across the middle. Crown somewhat 
convex, with the eyes as wide as the pronotum, evenly rounded in 
front, not or scarcely longer in the middle than at the sides. Side 
margins of pronotum sharp, of moderate length, hinder angles 
obliquely truncate. Elytra conyolute at the apex, much longer 
than the abdomen, with several irregularly-disposed white trans- 
verse nerves ; appendix ample. 
The species of this genus are all very much alike in
