84 OETHOPTEEA. 



comparatively few veins, rather narrow, the scapular area gently dilated, and the apex evenly rounded. 

 Hind femora compressed, moderately broad on the basal half, more slender apically, the carinae smooth. 

 Hind tibiae with 13-14 spines in the outer row. Valves of the ovipositor free, fairly slender, evenly 

 curved apically. 



1. Parachloebata pratensis, sp. n. (Tab. I. figg. 10, 10 «, $ .) 



Parachloebata prattensis (sic), Sauss. ined. 



(general colour light brownish-testaceous, streaked along the upper edge of the sides of the pronotum to the 

 transverse sulcus, and beyond the disc to the hind edge, with black. There are also two narrow dark 

 bands, enclosing a wider light one on the occiput, beginning at the back edges of the fastigium and 

 continuing to the pronotum. Tegmina with a prominent subcostal green stripe, reaching from the base 

 to beyond the middle, their general colour cinereous. Wings, as showing through the tegmina, slightly 

 infuscated. Hind femora internally and on the upper edge of the disc, along with the apex of the hind 

 tibiae, infuscated. 



Length of body, $ , 27 ; of pronotum 5, of tegmina 21, of hind femora 155 millim.

L1NOCERATIUM, gen. nov. 



Bearing a general resemblance to Orphulella, but differing from that genus in the more slender form, narrower 

 elytra, the almost complete obliteration of the lateral carinae on the anterior lobe of the pronotum, and 

 the much larger and more prominent eyes. 



Head rather large, the occiput ascending above the plane of the disc of the pronotum ; the eyes large, promi- 

 nent, semiglobular in the 3 , a little pointed above in the $ ; vertex of medium width, about half as 

 wide as the shorter diameter of the eyes ( $ ), or somewhat less ( tf ), deeply sulcate, and with a faint 

 median carina at the bottom near its front margin, the bounding walls high, meeting at front in a right 

 angle in the $ , somewhat acute in the d ; lateral foveolae present, but not very decided, varying from 

 linear to elongate triangular. Frontal costa fairly prominent, narrow above, gradually widening below, 

 continuous and sulcate to the clypeus. Antennae of medium length, filiform. Face short, straight, 

 oblique. Pronotum considerably widened behind, the two lobes of about equal length, the lateral carinae 

 nearly obliterated, and arcuate on the anterior, more pronounced and strongly divergent on the posterior 

 lobe ; hind border evenly rounded, the sides higher than long, and with the anterior portion of the lower 

 edge profoundly, obliquely truncate. Tegmina long, narrow, reaching beyond the tip of the abdomen in 

 both sexes, the apex evenly rounded, the veius and veinlets feeble. Posterior femora moderately heavy, 

 about reaching ( $ ) or greatly surpassing ( S ) the tip of the abdomen. Hind tibiae provided with nine 

 or ten spines in the outer row. Abdomen slender, in the c? not especially modified, but with the supra- 

 anal plate triangular, the apical half bent downward and separated from the anterior portion by a trans- 

 verse carina. Cerci moderately heavy and evenly tapering, about three and one-half times as long as the 

 extreme basal width. 



l. Linoceratium boucardi, sp. n. 



General colour of the <$ (the $ relatively more uniform in tint) pale testaceous, with a rather broad dusky 

 band on each side, beginning at the hind margin of the eyes and traversing the upper half of the sides of the 

 pronotum and pleura to the base of the abdomen. The latter with two or three rather large patches of 

 the same colour on the sides. Apex of hind femora and base of tibiae also dusky. Tegmina above with the 

 disc of the pronotum and the middle of the occiput pale testaceous, inclining to greenish in the tf darker 

 in the $ . The dusky band of the sides of the pronotum crosses over to the sides of the disc on the hind 

 lobe. Costal edge and discal area of the tegmina uniformly fuliginous in the tf » but in the single $ 

 specimen at hand shows heavy flecking on the basal portion, the apical part in the latter uniformly dark 

 as in the c? • Wings apparently fuliginous throughout.
