' 4. H. OAxus Mshl. (Plate I. fig. 1.) 



H. oaxus Mshl. Ann. Nat. Hist. (7) x. p. 416 (1902). 



Long. 23-34, lat. 8|-9 mm. 



Head convex, bare, punctuation close but faint on vertex, 

 deeper and more scattered in fi-ont, forehead rather I'etuse and 

 with two faint rounded impressions ; anteocular furrows distinct. 

 Rostrwm cut off from head by a deep dorsal incision, almost as 

 long as head and prothorax, distinctly curved, subpai'allel from 

 base to beyond middle, then gradually dilated to apex. Upper 

 surface convex in the basal part, which is smooth, shiny, and with 

 fine sparse punctuation, very shallowly excavate towards apex, 

 where the punctures are much closer and deeper ; lateral sulci 

 strong and deep, the intervening carina narrow and undulating, 

 the lower pair longer, the upper pair scarcely uniting at base ; 

 scrobes deep, lateral and parallel with sulci ; inferior basal fui'row 

 very broad and deep. Antennce with scape just reaching eye ; 

 2nd joint of funicle longer than 1st in (5' , subequal in § . Pro- 

 thorax rather broader than long, apex about as broad as base, 

 which is equal to the length in 5 , but narrower in S , sides 

 distinctly rounded, bi'oadest about middle, dorsal anterioi' margin 

 truncate, ocular lobes sti'ongly developed. Upper surface slightly 

 convex, fairly closely set with large elevated i-ounded tubercles 

 bearing depressed setae and leaving a narrow central furrow 

 without a carina ; scaling absent. Elytra oblongo-ovate, shoulders 

 I'ounded and more prominent in 5 1 sides slightly rounded, 

 broadest before middle, apices slightly and bluntly projecting in 

 (S , with sharp pai-allel processes in $ 1 mm. long. Upper 

 surface convex, the doi'sal striae simply punctate, the outer ones 

 granulate ; interval 1 quite smooth to near the declivity, but with 

 distinct granules from there to apex ; interval 2 quite smooth 

 throughout ; 3, 5, and 7 with tubercles strongly depressed to 

 beyond middle, then sharply conical, those on 3 being specially 

 prominent and continued right on to the apical processes in both 

 sexes ; intervals 4 and 6 with rows of depressed tubercles ceasing 

 beyond middle ; tubercles almost entirely devoid of setae. Elytra 

 bare and with a strong dull bronze reflexion. Legs without 

 scaling ; femora finety punctured at base, impunctate in middle 

 and very coarsely punctured at apex ; the posterior and anterior 

 tibiae strongly curved in S , especially the former ; joints 2 and 

 3 of posterior tarsi subequal, the 1st a little longer. 



Cape Coloxy. 



Type in the British Museum. 



"Very nearly allied to II. verrucosus L., but in addition to the 

 distinctions mentioned in the key, it differs in having the thoracic 

 tubercles more elevated ; the discal portions of intervals 1 and 3 

 near the base are quite plane and smooth, and not tuberculate or 

 carinate ; the discal punctures on the elytra are deep and simple, 

 whereas in verrucosus they are shallow and with a small but 

 distinct granule at the side of each.
