and white apical angles ; terebra exserted, black and apically pale ; 

 hypopygium large and apically acuminate. Legs short and somewhat 

 stout; calcaria, all the coxae except base of hind ones, apices of anterior 

 femora and inner side of their tibiae, pure white; tarsal claws strongly 

 pectinate. Wings small and broad, hyaline with stigma and nervures 

 black ; lower basal uervure antefurcal, areolet subquadrate. Length, 

 8 mm. A very typical species of this distinct genus. 



Captured at Chinde in Mozambique, Portuguese East Africa, by 

 K. H. Barnard, during November, 1912.

? only. A somewhat bright red species with the black antennae, 

 abdomen and legs all white-marked. Head posteriorly, mandibles at 

 both extremities and apex of clypeus black ; orbits not white-marked. 

 Scape red-dotted beneath, and a central flagellar baud white. Thorax 

 with small anteraclical white callosity, and the whole sternum black ; 

 postscutellum red. Abdomen black with apical angles of two basal 

 segments, and the anus, white-marked ; postpetiole glabrous with only 

 a row of punctures before its apex ; hypopygium covering terebral base 

 but not apically produced. Legs black with only apices of front femora 

 and the inner side of the anterior tibiae, with all calcaria, white; claws 

 not pectinate. Wings slightly but distinctly infumate. Length, 7 mm. 



The position of the Listrodromides, and their very right to Tribal rank, 

 are yet uncertain: this species, compared with the last, goes some way 

 to uphold Prof. Thomson's view (Opusc, Ent. xix, p. 2099) that the 

 genera Ijistrodromus and Neotypus which have pectinate tarsal claws, 

 and Anisobas which has not, form a small and compact group among 

 the Amblypygini, sharing the following characters in common: Clypeus 

 not discreted, its lateral foveae obsolete ; genal costa continuous ; 

 antennae inserted high on frons, with scapes not further from each 

 other than from the eyes ; metauotal costulae entire, the dentiparal 

 area externally arcuate ; tibiae submutic, the hind ones hardly longer 

 than, their femora ; lower basal uervure oblique, autefurcal and pretty 

 well straight. The above two species possess all these characters 

 and, indeed, differ inter se only in the features indicated under the 

 latter. 



The type was captured at Stellenbosch, Cape Colony, by R. M. 

 Lightfoot, during September, 1913.
