Nine examples seen. This species, owing to its long, 

 narrow, rostrate head (suggestive of that of the American 

 genus Tanaops), should j)erhaps be removed to a separate 

 genus; but it is connected with the typical forms by P. 

 angustissinms and P. metallicus. The present insect has 

 the general facies of a Malachiid. 



23. Pagurodactylus masaicus, n. sp. 



(^. More elongate and larger than P. rosiralis; nigro-aencous or 

 black, the testaceous apical spot on the elytra extending forward at 

 the sides to about the middle and also for a short distance up the 

 suture ; the head and prothorax less shining, densety alutaceous, and 

 sparsely, minutely punctate, the head equally elongate, the prothorax 

 relatively longer, the elytral margins in $ more broadly explanate 

 in their apical half, the anterior tarsi of 5" as in P. rosiralis. 



Length (with head raised and extended forward) 3|-4 mm. ((^$). 



Hah. E. Africa, Mau, Masai Reserve {Capf. A. 0. 

 LvcJcman : 7. i and 4. iii, 1914). 



One (^, two $9- ^ form of P. rosiralis requiring a 

 distinctive name. 



Dasytophasis, n. gen. 



Dasytophasis Peringuey, in litt. 



Very near Pagurodactylus Gorh. (lugens, angusiulus, etc.) ; anterior 

 tarsi slender in both sexes, narrow, joints 1 and 2 longer than 3, the 

 claws small, not elongated or unequal in (^, feebly subangularly 

 widened near the base; antennal joints 5 and 6 or 5 only dentiform 

 in (^, simple in $ ; elytral sculpture unequal ; lateral vesicles wanting. 



Type, D. capicola. 



This genus was named long ago by Dr. Peringuey, but 

 not described, though both sexes were found by Raft'ray 

 near Cape Town, and specimens given by him to the Cape 

 Town Museum. It cannot be included under Paguro- 

 dadylns as defined by Gorham. 



The ^ of D. capicola has joints 7-11 of the antennae 

 elongated, and 5 and 6 together forming a grasping-organ ; 

 that of D. {Attains) alhofasciatus Gorh., which must be 

 included in the same genus, has these organs short in both 

 sexes, and the fifth only dentiform.
