Orthoptera in the British Museum. 131 
Genus Brsutus I. Bol. 
1. Bibulus brunni (Gig.-Tos). 
1901. Hulprepocnemis| coerulescens Brunn (nec Stil ?); 
Mitt. Naturhist. Mus. Hamburg, xvi, p. 264, no. 132. 
1907. Z[ylotropidius] brunni Giglio-Tos, Boll. Mus. Torino, 
_ xxii, 552, p. 31. 
1914. Bibulus brunni I. Bolivar, Trab. Mus. Madrid, ser. 
Zool., N 20, p. 31. 
T am still not quite sure that coerulescens Stil is actually 
distinct from brunni ; a definite solution of this question 
is possible only by examining Stiil’s type. 
British Museum specimens: British EK. Africa (C. S. 
Betton), 12; Sokotra, 1 9 (bearmg M. Burr’s label : “ Cata- 
loipus oberthiire Bol,’’). 
2. Bibulus desertus, sp. n. 
General coloration light buff. Face reclinate; frontal ridge flat, 
punctured, with very slightly raised lateral carinae, a little narrowed 
towards clypeus and more distinctly, but still feebly, narrowed to- 
wards fastigium. Fastigium of the vertex rotundate, with ovat 
impression and low, acute median carinula, which is more raised 
between the eyes. Occiput unicolorous with but slight trace of 
brownish spot before the middle of the hind margin. Antennae of 
general colour above and blackened in distal two-thirds below, 
slightly widened beyond the middle, a little longer than head and 
pronotum taken together. Pronotum with a narrow chocolate- 
brown longitudinal band, which gradually widens backwards, 
rather suddenly narrows in metazona, its width at the fore margin 
being a little less than that at the hind margin and half the width 
of the widest portion, which is in the middle of metazona; marginal 
parts of the band are more intensely coloured than its interior part; 
lateral bands of pronotum are light buff, their width at the fore 
margin being equal to the width of median stripe, while they are 
widened in the hind half of metazona; the whole disk of pronotum 
is not flat but slightly tectiform with a raised median carina, 
which is deeply interrupted by three transverse sulci; prozona 
distinctly longer than metazona; hind margin obtusely angulate ; 
lateral lobes unicolorous, coriaceous throughout but more densely 
in metazona. Prosternal tubercle flattened anteriorly, with wide 
truncate apex. Elytra longer than abdomen, with all veins, except 
in the anal field, brownish, with indistinct brownish transverse bands. 
Wings bluish hyaline, slightly infumated towards their apex. Hind
