obsolete. Another $, from Pretoria {Bucknill), with the 

 dark markings on the elytra reduced to a small hmneral 

 spot and an incomplete post-median fascia, may belong 

 to the same species (?). Till males of P. marginipennis 

 are obtained from the type-locality, the identification of 

 that sex of the species must remain in doubt. A Bothaville 

 ^ has been retained for the British Museum collection. 



15. Pagurodactylus nigrosetosus, n. sp. 



^. Very like P. ceplialotes ; the elytra testaceous, the puncturing 

 sparser and a little stronger, the black setae very long ; the head not 

 wider than the prothorax, obliquely narrowed from the eyes back- 

 ward, the cavity on the vertex broad and very deep, the punctur- 

 ing not so coarse ; the antennae slender (as in $ P. cephalotes) ; the 

 elytral puncturing coarse and rather diffuse; the anterior tarsi 

 similarly formed. 



I^ength 2|-3-| mm. 



Hab. S. Africa, Frere, Natal {Dr.Marshall : iii, 1896). 



Four males, varying in the development of the head, 

 the latter without trace of the rounded tumid space behind 

 each eye, and the cavity on the vertex broader and deeper. 



16. Pagurodactylus debllis, n. sp. 



(^. Moderately elongate, shining, clothed with fine pubescence 

 intermixed with erect, black, bristly hairs; testaceous, the head in 

 part, the outer joints of the antennae, a patch on the prothorax, a 

 narrow, basally-widened, sutural stripe on the elytra extending from 

 the base to near the apex (sometimes dilated posteriorly into a large 

 patch or entirely obsolete), and metasternum, black or piceous ; the 

 head and elytra closely, the prothorax very sparsely, minutely, 

 punctate. Head barely as wide as the i^rothorax, smoother in 

 front, feebly foveate on the vertex; antennae a little longer and 

 stouter than in $. Prothorax transverse, rounded at the sides. 

 Elytra subparallel. Anterior tarsi thickened, joint 2 dentate at the 

 tip within, the upper claw longer and stouter than the lower one. 



$. Head small; antennal joints 6-10 transverse; elytra widened 

 posteiiorly ; anterior tarsi slender. 



Var. Elytra piceous, with the sides and apex only testaceous ($). 



Length 2|-nearly 3 mm. 



Hab. S. Africa, Howick, Natal (J. P. Cregoe, in AIus. 

 Brit, and Alus. Cape Toivfi). 



Eight cJcj", eight $$. Whether this form should be 

 considered more than a race of P. nigrosetosus is doubtful :
