1904.] OF THE GEKUS HIPPORRHINUS. 55 



base, as long as head and prothorax, strongly curved beyond 

 middle. Upper surface with a distinct continuous central furrow 

 (in some examples it is of nearly even width throughout, in others 

 markedly narrowei- in the middle), dilated at base into a large 

 rounded impression, finely aciculate and with sparse pale scaling ; 

 lateral sulci not meeting at base, the lower one much longer and 

 deeper than the upper and also strongly curved upwards at base ; 

 scrobes directed to beneath base of rostrum ; inferior basal f ui'row 

 pi*esent. Antennas with scape scarcely reaching eye ; the two 

 basal joints of funicle subequal. Prothorax much longer than the 

 width at base, which is broader than apex, sides dilated about 

 middle into a strong tuberculate spine, dorsal anterior margin 

 slightly convex, ocvilar lobes distinct. Upper surface almost 

 plane, unevenly and sparingly set with low rounded tubercles, 

 there being usually a single much larger one about middle on each 

 side of the central furrow, which latter contains a low carina ; 

 behind the apex is a broad and deep transverse impression almost 

 devoid of tubercles ; the apical portion is raised into a strong 

 callus, which is smooth and strongly punctured on its anterior 

 edge, but tuberculate behind ; tubercles bare and with short 

 depressed pale setaa, interstices with fairly dense light brown 

 scaling. Elytra elongato-ovate, shoulders sloping, sides gently 

 rounded, broadest about middle, apical processes very short but 

 broad, pointed, and divergent in $ , obsolete in (S . Upper surface 

 convex, with rows of shallow punctures sepai-ated by minute 

 granules ; interval 1 with a single regular row of small granules 

 vanishing near apex ; interval 2 with a short, apical, slightly 

 raised row of closely-set granules ; intervals 3, 5, and 7 slightly 

 raised and with rows of closely-set granules, generally more or 

 less duplicated ; 4 and 6 plane, oi- at most with a few isolated 

 granules near base ; granules bare and with pale depressed setfe, 

 interspaces fairly closely covered with very small light bi'own 

 scaling variegated with lighter spots, and usually with a conspi- 

 cuous broad paler band across the top of the declivity. Legs with 

 spai'se pale scaling, forming a denser ring near apex of femora ; 

 posterior tarsi with the joints of about the same width, 2nd 

 and 3rd subequal in length, 1st rather longer.

Father O'lSTeil finds this to be an uncommon species in his 

 neighbourhood, where it feeds on a conifer, the Bastard Yellow- 

 wood {Podocarpus elongata). 



Mr. Peringuey has kindly di-awn my attention to the fact that 

 Roelofs (Jorn. de Sciencias, Lisbon, 1887) has recorded this 

 species as having been taken by Welwitsch in Angola. Welwitsch's 

 captures are in the British Museum, and there being only two 

 species of Hipporrhi7ii^ H. ova7npoensis Per. and II. angolensis, 

 sp. nov. (nos. 75 & 76, infra), Roelofs' record is probably 

 incorrect.
