H. talpa Fahr. Ofv. K. Yet.-Akad. Fcirh. 1871, p. 217. 



Long. 8i-10, lat. 4-4| mm. 



Head coriaceous, squamose, convex on vertex, forehead flattened 

 and with a short central stria ; anteocular fiiiTows absent. 

 Rostrum not cnt off from head at base, as long as prothorax, 

 thick, curved and dilated towards apex. Upper surface squamose, 

 with five carinee, the outer ones uniting apically and the three 

 central ones converging towards base to form a stout erect 

 tubercle, which is more or less strongly dilated to apex and there 

 emarginate ; the central carina abbreviated anteriorly ; lateral 

 sulci shallow, esjoecially the lower pair which is much narrower 

 than the upper, both pairs unite at base ; scrobes lateral, very 

 shallow ; inferior basal fuiTOw deep. Antennce with scape reaching" 

 the middle of eye ; the two basal joints of funicle subequal. 

 Prothorax as long as broad in S , transverse in 2 , apex almost as 

 bi'oad as base, sides rounded, broadest about middle, dorsal 

 anterior margin truncate ; ocular lobes moderate. Upper surface 

 convex, closely set with small rounded granules, leaving a very 

 narrow central furrow without any carina ; granules bare, each 

 with a depressed pale seta, the interstices Avith brown scaling* 

 except for three narrow longitudinal white lines. Elytra ovate, 

 subacuminate in 5 i shoulders sloping, sides rounded, broadest 

 rather before middle, apical processes absent. Upper surface 

 convex, with shallow sulci, containing rows of indistinct punc- 

 tures separated by minute granules ; the intervals all of even 

 height, each with a row of small low granules, which are shiny 

 and bear depressed pale setse, the interspaces with dense brown 

 scaling variegated with grey ; on the juxta-su.tural intervals the 

 granules are not so distinct as towards the sides. Legs with grey 

 scaling ; posterior tarsi with the joints of about the same width, 

 2nd and 3rd subequal in length, 1st longer. 



Transvaal : Lydenburg [don. Dr. J. W. B. Gtmning]. Mashona- 

 LAND : Marandella's (6000 ft.). Port. E. Africa : Delagoa Bay 

 {H. Junod). 



Type in the Stockholm Museum. 



This species appears to vary a good deal in the development of 

 the rostral horn. In my Mashonaland examples this horn is 

 comparatively small, almost parallel-sided and very slightly emar- 

 ginate apically. In the series taken by Wahlberg (presumably in 

 the Transvaal) it is distinctly longer and dilated apically, and in 

 one specimen the dilatation is much more strongly marked than 

 in the rest.
