16. fH. SUBCORDATUS Gyl. 



H. suhcaudatus Gyl. Schh. Gen. Cure. v. p. 782 (1840). 



Head convex, dispersely punctured ; forehead plane, rugose ; 

 anteocular furrows not very deep. Rostrum cut off from head b}^ 

 a deep dorsal incision, elongate, but yet a little shorter than 

 thorax, deflected but scarcely curved, sides almost parallel 

 throughout. Upper surface with five smooth even carinse ; lateral 

 sulci deep, equal in length, the upper pair not uniting at base ; 

 scrobes deep, lateral and pai-allel to sulci ; inferior basal furrow 

 very deep. Antennce with scape just reaching eye ; the first joint 

 of f unicle a little longer than second. Frothorax elongate, as long- 

 as broad, length about equal to width at base, apex much narrower, 

 sides subparallel from base to middle, then rapidly narrowed 

 anteriorly, ocular lobes well developed. Upper surface convex, 

 closely set with large rounded depi'essed tubercles ; the central 

 furrow obsolete ; tubercles unipunctate, the interstices without 

 scaling. Elytra heart - shaped, strongly acuminate behind, 

 shoulders prominent, sides strongly rounded, broadest much 

 befoi'e middle, apical processes very small, tuberculiform. Upper 

 surface moderately convex, transversely rugose, with rows of la,rge 

 and remote but indistinct foveolse ; scaling absent, the elytiu 

 being bare, black and shiny. Legs elongate, rugose, with long- 

 black setse ; anterior pairs of tibiae strongly curved ; posterior 

 tarsi broad, the three joints subequal in length and breadth. 



" Oaffraria {Drege) " — teste Schonherr. 



Type in the Stockholm Museum. 



The only example of this peculiai- species which I have been 

 able to examine is Gyllenhal's unique type. Thecordiform elytra 

 and long legs give the insect a very distinct appearance, more 

 suggestive of a Western Adesmia than a Hipporrhiniis. It seems 

 probable that its real habitat is somewhere in the North-western 

 parts of the Cape Colony, and not Caffraria as stated by 

 Schonherr. 



17. H. ALBICINCTUS Gyl. 



H. alhicinctus Gyl. Schonh. Gen. Cure. v. p. 711 (1840). 



Long. 21-22, lat. 10-10| mm. 



Head convex, finely shagreened on vertex, and with very deep 

 scattered punctures ; forehead flattened or shallowly impressed, 

 very rugose, and with a low central carina ; anteocular furrows 

 present but not very distinct. RostruTtn sepai-ated from head by 

 a basal incision, as long as head and prothorax, curved beyond 

 middle. Upper surface with five broad smooth carinse, the central 

 one usually bearing a faint stria, the intervening furrows coarsely 

 punctured and with white scaling ; lateral sulci deep, meeting at 

 base, the upper pair rather longer ; scrobes lateral, parallel to 

 sulci ; inferior basal furrow very broad and deep. Anfen7ice with 

 fine white setae ; scape not reaching eye, the two basal joints af 

 funicle subequal. Frothorax transverse, apex narrower than base,
