gidium ; pygidium of the female produced into the middle into a 

 conspicuous, transverse rounded ledge, overhanging an apical longi-

Syrichthomorphus termitophilus, 

 Plate XL., fig. 30. 



Female : Piceous or chestnut-brown, shining, densely but briefly 

 fringed with fulvous hairs along the margin of the prothorax and 

 that of the elytra to about the median part of the latter ; head 

 scrobiculate, clypeus very sharply reflexed at apex, genge distinct^ 

 somewhat triangular, the anterior part of the head owing to the 

 reflexed anterior part of the clypeus is concave, and past the frontal 

 part there is a very short, median transverse carina ; prothorax 

 ampliate laterally and rounded at middle, covered on the anterior 

 part with nearly confluent, rugose foveae, and with round, foveate 

 punctures behind, in the anterior margin there is a distinct, sharp, 

 median tubercle, and at a short distance from it begins a longi- 

 tudinal, very deep groove, reaching nearly to the base ; elytra 

 convex, especially behind, a little ampliate laterally from about the 

 median part and covered with round, small, cicatricose punctures ; 

 the striae are also punctate but moderately distinct, and have a single 

 series, often worn off, of remotely distant fulvous long setae ; pro- 

 pygidium scabrose, without trace of stridulating organs and briefly 

 pubescent ; pygidium with the upper part produced into a rounded, 

 convex ledge overhanging the lower half in the median part of which 

 there is a longitudinal impression divided into two by a median, 

 also longitudinal carina; abdomen nearly glabrous; sternum densely 

 villose. 



Male unknown. 



Length 18-26 mm. ; width 9f-13 mm. 



Hah. Transvaal (Boksburg, Lydenburg). 



This species seems to have the same habits as Pseudocyphonistes 

 corniculatus . Mr. Harold Fry has found it with numerous larvae 

 on the underground sides of a small mound of Termes trinervius, 

 Eamb., on which they had made quite an excavation; they were 

 feeding on the nest itself. 



PSEUDOSYEICHTHUS, n. gen. 

 Mentum in the shape of a very elongate triangle with the apical 

 part deeply incised triangularly for nearly all the width, diagonally 

 impressed on each side of the base, but not carinate, ligular part
