Margins of pronotum beneath and mediastinal area of tegmina 

 beneath bright rufo-castaneous. Abdomen and legs rufo -testaceous. 

 Supra-anal lamina sub-quadrate, apex slightly emarginate, barely 

 exceeded by the sub-genital lamina which is asymmetrical and 

 furnished with two styles. 



5 . Similar bnt rather darker in colour, distance of eyes apart 

 rather greater than length of 1st antennal joint. Antennae piceous, 

 castaneous at base. Posterior part of pronotum concolorous with 

 anterior part. Tegmina broader, their outer margin very sinuate. 

 Wings with anterior part suffused with rufo-castaneous. 



$. Total length 22 mm. ; length of body 16 mm. ; length of 

 tegmina 20 mm. ; pronotum 6'8 mm. x 8 mm. 



$ . Total length 28 mm. ; length of body 21 mm. ; length of 

 tegmina 25 mm. ; pronotixm 8*5 mm. x 10'9 mm. 



SOMALILAND, Brava (Genoa Mus., types $ and $); 

 German E. Africa, Lake Jipe, Katona (Budapest Mus.). 



The species is perhaps most nearly related to G. lati- 

 costa, Walk., but is distinguished by the well-defined 

 lyrate markings on the pronotum. The specimen from 

 Katona is rather larger than the type $ , but otherwise is 

 identical.

^ . Testaceous. Distance apart of eyes on vertex of head equal to 

 length of 1st antennal joint ; frons with castaneous macula ; neither 

 vertex nor frons striate. Antennae rufo-fuscous, basal third rufo- 

 testaceous. Pronotum with clearly defined lyrate marking. Teg- 

 mina rather broad, mottled with testaceous, a macula on disc and a 

 curved fascia at apex, rufescent ; the piceous spot between radial and 

 mediastinal veins obsolescent or absent. Wings hyaline, the marg- 

 inal field flavo-testaceous, ulnar vein with 10 rami, 7 being incom- 

 plete. Abdomen and legs rufo-testaceous ; supra-anal lamina sub- 

 quadrate, apex not emarginate, barely surpassing the sub-genital 

 plate which is small and slightly asymmetrical. Tarsi rather short. 



$ . Similar, but eyes a little farther apart ; tegmina broader ;
