Species of Fossorial Hymcnoptera from Africa 758 



closely with very fine pale golden pubescence, which in some lights 

 becomes almost silvery. 



Hob. British East Africa, near Wangi, coast of main- 

 land (>S'. A. Neave), February 21-22. 

 Type in B. M. 



Motes liroides, sp. n. 



9 . Nigra, pallide aureo-pilosa ; tarsis tegulisque f usco-ferrugineis ; 

 alis flavis, apice late fuscis ; segmento mediano transverse striate. 



Long. 16 mm. 



9 . Clypeus short, very feebly rounded at the apex, with an 

 obscure carina from the base not reaching the apex. Second joint 

 of the flagellum twice as long as the first and distinctly longer than 

 the third. Eyes separated on the vertex by a distance equal to the 

 length of the second joint of the flagellum. Closely and very 

 minutely punctured, the median segment distinctly transversely 

 striated, longer than broad. The whole dorsal surface of the head, 

 thorax, median segment and abdomen more or less densely clothed 

 with very delicate pale golden pubescence ; the apical dorsal segment 

 closely covered with short fulvous setae, the sides of the segment 

 converging strongly towards the apex, which is rather broadly 

 rounded and less than half as wide as the base of the segment. All 

 the tarsal ungues have a small but distinct tooth close to the middle. 

 The two recurrent nervures are received close together more than 

 twice as far from the basal angle of the second cubital cell as from 

 each other. 



ffab. British East Africa, Witu (S. A. Neave), 

 February 25-28. 



Type in B. M. 



This is another case of close resemblance to Ziris 

 haemorrhoidalis, Fabr., but the structure is different. It 

 may be easily distinguished from the West African species 

 M. odontofora, Kohl, and M. cyphononyx, Kohl, by the 

 strongly convergent sides of the pygidial area and the 

 different colour of the wings, which are quite as dark 

 as in the most highly coloured specimens of Liris 

 haemm'rhoidalis.
