374 Mr. C. N. Barker on 



•wliich arc subacute ; depressed above, moderately deeply 

 striate, intervals, except about posterior declivity, jilane and 

 densely punctulate ; very distinct seriate punctures on 

 intervals 3, 5, and 7, and the si)ace between eighth stria and 

 retlexed border coarsely sculptured. 



Underside very deep red, shading to red about middle of 

 abdomen and nietasterna, glabrous and smooth, except for 

 some remote punctures on nieso- and metasternal parts. 



Tlie shape of the prothorax is not unlike that of //. connexus, 

 Per. ; it is equally transverse, the front angles are a little 

 more depressed and the hind angles sharp instead of rounded. 



The metallic-green lustre is present on head and prothorax, 

 as well as on the elytra, which differentiates it from other 

 species in which an evanescent iridescence is present on the 

 elytra only. Being so distinct a species, I have ventured to 

 describe it from a single male example. 



Hab. Maraudella, Rhodesia (G. A. K. Marshall, 1897). 



Hypolithus differens, sp. n. 



Length 11;^ mm, ; width 4j mm. 



Black, moderately shiny above, dark red to piceous 

 beneath ; legs, antenna?, palpi, labrum (centre infuscate), and 

 piothoracic margins (narrowly) reddish testaceous. 



Head finely, densely aciculate-punctate, shiny, frontal 

 depressions shallow, transverse suture fine. 



Prothorax very transverse (J5J by 2^ mm.), front bi- 

 sinuate, angles produced, briefly rounded, sides very gently 

 ampliate to middle, thence straight and hardly narrowed to 

 posterior angles, which are obtusely right; base much wider 

 than apex, very shallowly emarginate in the middle, disc 

 nearly plane, moderately declivous frontally, densely, finely 

 punctulate, median line short, sides above and base broadly 

 shallowly impressed, densely rugosely punctate ; reflexed 

 margins narrow. 



Elytra of nearly equal width with prothorax at bases, 

 shoulders subquaclrate, briefly rounded, very briefly am- 

 pliated below, thence a little obliquely inclined to beyond 

 middle and gradually rounded to and slightly sinuose 

 before apex ; hardly convex above, stride fine, intervals broad 

 and quite plane, moderately densely but not confluently 

 punctulate, numbers three and five with distinct seriate 

 punctures. 



Judging by description [vide Trans. Phil. Soc. vol. vii. 

 p. 435), it is very nearly related to //. integer, Per. The 

 following are points upon which they aj)pear to differ : —
