€8 MK. G. A. K. MARSHALL OX COLEOPTERA [Jan. 19, 



dorsal anterior margin ti-uncate, ocular lobes well developed. 

 Upper surface slightly convex, unevenly set with rounded and 

 I'ather distant tubercles, leaving a distinct centi-al furrow con- 

 taining a low carina and with a low tubercular callus just behind 

 apex ; tubercles bare, with depi'essed seta?, the interstices with thin 

 brown scaling. Elytra ovate, narrower in c? , shoulders sloping, 

 sides rounded, broadest about middle, apical processes sharpl}^ 

 conical and divergent in both sexes. Upper suiface convex, with 

 fairly regular i-ows of granules in lieu of punctui-es ; intei'val 1 

 with a row of distant gi-anviles becoming much smaller towards 

 apex ; interval 2 with a shoi-t subcristate row of small conical 

 tubercles on the declivity, and occasionally one or two isolated 

 tubercles on the basal part ; intervals 3, 5, and 7 with complete 

 rows of small conical tubercles ; 4 and 6 usually devoid of tubercles, 

 but sometimes with an abbreviated or inteiTupted I'ow ; tubercles 

 bare, sometimes with very short depressed setae, the intei-stices 

 with brown scaling. Legs clothed with thin white depressed sette ; 

 posterior tarsi broad, the 3rd joint scarcely broader than the 

 others, 2nd and 3rd subequal in length.

Type in the Stockholm Museum. 



This insect is most nearly allied to recurvus F. and alhol'meatus 

 Fahr., all three being chai-actei'ised by the depth and continuity 

 of the rostral furrow. H. sulcirostris differs from the others in 

 lacking the basal dilatation of this f ui-row ; the impression on the 

 forehead is much broader and deeper ; the thoracic tubercles are 

 much fewer and more distant ; the discal tubei'cles on the elytra 

 are more conical and further apart, and the apical processes are 

 not turned upwards. 



The type specimens, as well as all others which I have seen from 

 the Transvaal, are of a brown colour owing to the dense scaling ; 

 but six specimens taken by Mr. Hutchinson and myself, on the 

 foot-hills of the Drakensberg, have the scales so minute and 

 widely scattered as to make them appear quite bare and black 

 to the unaided eye. These insects we found on the branches of 

 a Protect, and it was by no means easy to detect them upon the 

 black bark, with which theii- rough elytra assimilated so well. 

 Possibly this is a local mountain form which has adapted itself to 

 special conditions.
