688 On new Gras.sIioppers from East Africa. 



Face strongly punctured : frontal ridge straight in profile, 

 scarcely narrowed at the fastigium, very slightly narrowed 

 downwards, almost parallel-sided, sulcate throughout, except 

 at the fastigium, distinctly punctured, with the margins 

 smooth. Fastigium of the vertex distinctly sloping, widened 

 forwards, rotundato-truncate in front^ much longer thau 

 broad, slightly impressed, punctured. Distance between 

 the eyes slightly narrower than the antennae. Pronotum 

 distinctly punctured all over, except the callous lower 

 portion of the lateral lobes on the prozona and two 

 indefinite smooth spots at the upper margin of the lobes ; 

 transverse sulci not strong, but distinct, cutting the median 

 keel, which is distinct throughout, though low and irregular 

 owing to the puncturation ; metazona subequal to the pro- 

 zona, obtusely angulate behind ; lateral lobes forming no 

 angles with the disc. Prosternal tubercle subconical, dis- 

 tinctly inclined backwards, with the apex obtuse. Meso- 

 sternal interspace broader than the frontal ridge, longer 

 than broad. Metasternal lobes contiguous. Elytra extending 

 a little beyond the hind knees. Front and middle femora 

 somewhat incrassate. Cerci extending beyond the apex of 

 the supra-anal plate, somewhat compressed basally, gradually 

 narrowed and incurved towards the apical part, which is 

 rather suddenly bent inwards and upwards, so that its lower 

 outer side forms a distinct angle with the rest of the cercns. 

 General coloration reddish testaceous. Antennae dirty 

 olivaceous, irregularly marmorated with reddish. Face and 

 the lower part of the cheeks pale ; some indistinct greenish- 

 grey markings on the lateral facial carinse ; an indistinct 

 brown fascia, widened posteriorly, on the occiput ; a broad 

 black postocular fascia, including a round pale spot below 

 the middle. Pronotum reddish brown, somewhat darkened 

 along the median keel ; hind margin somewhat paler ; lateral 

 lobes with more than the lower third pale, callous on the 

 prozona ; the upper part very dark reddish brown between 

 tiie front margin and the second sulcus, paler between the 

 second and third sulcus, concolorous with the disc on the 

 metazona. Elytra testaceous, reddish basally ; the middle 

 third of the marginal field somewhat blackened ; some 

 scarcely distinct small dark spots scattered elsewhere. 

 Wings yellowish basally, somewhat infumate towards the 

 apex. AH legs very pale olivaceous ; hind femora somewhat 

 reddish above ; the upper inner area with a small spot near 

 the base, a second one of the same size just before the 

 middle, both of them extending a little into the inner middle 

 area, a third subobsolete spot beyond the middle, which
