Ethiopian Region. It seems to be most nearly allied to 

 mesostenus, llandl., which I liave not seen, but is more finely 

 and sparsely punctured. As in other species of the genus, 

 there is a strong elbow close to the cubitus on the first 

 transverse cubital nervure, from which on the inner side 

 branches the stump of a nervure continued as a scar to the 

 base of the stigma. 



Gorytes {Harpactus) escalera, sp. n. 



$ . Nigra ; clypeo, meaopleuris, scutello, posiscutello, segmento 

 dorsali secundo basi et linea lata, longitudinali, mediana, seg- 

 mento ventrali secundo fascia lata interrupta, segmeiitoquo quinto 

 dorsali albido-flavis ; alls fusco-hyalinis, venis fuscis. 



Long. 7 mra. 



$ . Eyes almost parallel on the inner margin ; posterior 

 ocelli twice as far from each other as from the eyes. Clypeus 

 broad, transverse at the apex. Head and thorax opaque, 

 very finely and closely [junctured, mesopleurse and abdomen 

 more sparsely but a little niore deeply punctured and shining ; 

 a transverse crenulated groove between the mcsonotum 

 and the scutellum. Second ventral segment only slightly 

 convex ; first abdominal segment broad and short ; pygidial 

 area well defined, fiat, rather narrowly triangular, and more 

 deeply punctured than the other segments. Basal area of 

 the median segment well defined, coarsely longitudinally 

 rugose-striate, with a distinct median sulcus. Third abscissa 

 of the radius longer than the second by one-quarter, both 

 recurrent nervures received by tlie second cubital cell, the 

 distance between them on the cubitus scarcely greater than 

 that between the second recurrent nervure and the apex of 

 the second cubital cell. Cubitus of the hind wing origin- 

 ating distinctly beyond the transverse median nervure. 



Hab. Mogador, S.W. Morocco {Escalera). 



The absence of the ferruginous colouring prevalent in the 

 group and the great extent of the yellow markings on the 

 mesopleurse and second abdominal segment distinguish this 

 species at a glance. It is more robust than most of the 

 allied species, and the pygidial area is more distinctly 

 margined.
