290 Mr. W. L. Distant on 



Dist., from wliicli it differs by the non-truncate long concave 

 apices to the two longest abdominal lobes ; basal joint of 

 antennae stoutest and very longly spined, a little longer than 

 second, which is about hulf as short again as third, fourth 

 joint shortest, incrassate, brownish ochraceous. 



Long. 10 mm. 



Ilab. Transvaal ; Pretoria^ Aapies River. 



A specimen was kindly sent to me by Mr. H. Fry, of 

 Johannesburg, after whom I have named the species. 



Fam. Lygseidae. 

 Subfam. IIetemoqa-Steinje. 



Masoas, gen. nov. 



Subelongate; head a little longer than broad, strongly 

 sinuately narrowed in front of eyes, tlie anterior lateral 

 margins straight and ridged; anteniice four-jointed, first joint 

 scarcely reaching apex of head and almost as long as second, 

 third and fourth thickened, pilose, third longest ; rostrum 

 reaching the anterior coxa?, first joint not reaching base of 

 head; eyes projecting a little beyond anterior margin of pro- 

 notum, which is about as long as broad at base, a little 

 narrowed anteriorly, centrally transversely impressed ; scu- 

 tellum subtriangular ; membrane with several basal cells; 

 anterior femora somewhat strongly thickened, beneath near 

 apex with a distinct spine, followed by a few very small 

 sj)ines, anterior tibise a little shorter than the femora. 



The incrassated and spined anterior femora, together with 

 the short rostrum, give this genus a resemblance to the 

 Pachygronthinaj ; but the basal cells to the membrane prompt 

 its insertion in the Heterogastrinae.
