1904.] OF THE GEXUS HIPPORRHIXUS. 45 



Head convex, with sparse punctures and squamse, forehead with 

 a rounded impression ; anteocular furrows distinct. Rostrum 

 separated from head by a deep dorsal incision, as long as head and 

 prothorax, thick, strongly curved and slightly dilated near apex. 

 Upper surface with five strong smooth narrow carinse of even 

 height ; lateral sulci of about equal length, the upper pair rather 

 deeper and meeting at base ; scrobes deep, lateral and oblique ; 

 inferior basal furrow very deep. Antennce with scape barely 

 reaching eye; the two basal joints of funicle subequal. Pro- 

 thorax transverse, more distinctly so in $ , the length equal to 

 the width at base in 5 > greater in S ; apex leather narrower than 

 base, sides strongly rounded, broadest about middle, dorsal 

 anterior margin truncate, ocular lobes moderate. Upper surface 

 rather convex, closely set with small elevated granular tubercles, 

 leaving a narrow central furrow without a carina ; tubercles bare 

 and with very short depressed setse, the interstices with dark 

 scaling a.nd three narrow pale lines. Elytra ovate, much narrower 

 in S , shoulders roundedly prominent, sides distinctly rounded, 

 broadest about middle, apical processes very small and contiguous 

 in both sexes. Upper surface convex, distinctly sulcate, sulci 

 with rows of shallow punctures separated by small granules ; 

 intervals all evenly raised, subcostate, and with regular rows of 

 large shiny granules, each bearing a depressed dai'k seta, the 

 interspaces with uneven scaling, being variegated with small 

 patches of brown, fulvous, or white. Legs piceous, with fine pale 

 pubescence ; posterior tarsi with the 2nd joint a trifle narrower 

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

Type in the British Museum, 



From the allied H. lacunosus Gyl. this insect differs in its 

 thinner, deeply sulcate and less curved rostrum; the thoracic 

 tubercles are not depressed ; the sides of the elytra are more 

 ampliated, and in the $ the suture is not nearly so much elevated 

 on the declivity.

Long. 12, lat. 6 mm. 



Head convex, bare, and with faint scattered punctures, forehead 

 with a slight central depression; anteocular furrows deep and 

 complete. Rostrum as long as head and prothorax, cut off from 

 head by a deep dorsal incision, distinctly curved and very 

 gradually dilated from base to apex. Upper surface nearly plane, 

 with three fine carinae, the central one being the shortest and 

 vanishing beyond middle ; punctuation indefinite, scaling absent ; 

 lateral sulci broad and deep, separated by a strong costa bearing 

 a faint stria, the upper pair only meeting at base ; scrobes sti-aight 

 and lateral, almost parallel to the sulci ; inferior basal furrow 

 very deep. Antennm with scape just reaching eye ; the two basal 

 joints of funicle subequal, Prothorax slightly transverse, the
