94 LORD HOWE ISLAND. 



slightly narrowed behind, strongly punctate-striate, the striae less impressed 

 near the sides. Legs pieeous ; tarsi pitchy. Length 4^ — 5^ mm. 



This species appears to approach Aphanocorynes depressus, "Woll., but the 

 the head and pro thorax are much more strongly punctured, and the elytra 

 more deeply striate ; the prothorax is also longer, more convex, and 

 decidedly more constricted in front. 



COSSOXUS LETHABGICUS, Sp. nOV. 



Elongate, parallel-sided, much depressed, black, shining ; prothorax 

 strongly and sparingly punctured throughout ; the elytra strongly punctate- 

 striate. 



Head finely punctured, with a tolerably strong impression in the middle 

 between the eyes ; rostrum rather short, dilated in front, finely and evenly 

 punctured. Eyes moderately prominent, finely granulated. Antennae pitchy, 

 the club covered with fine gray pubescence. Prothorax rather longer than 

 broad, narrowed and somewhat constricted in front, strongly and sparingly 

 punctured, a median impunctate space ; the sides rather strongly rounded ; 

 posterior margin straight, slightly impressed on each side of the middle. 

 Scutellum small, impunctate. Elytra rather less than twice as long as the 

 head and prothorax together, at the base rather broader than the latter, 

 strongly punctate-striate, the interstices moderately broad and extremely 

 finely punctured; shoulders not very prominent; sides nearly parallel, 

 rounded behind. Legs moderately robust, reddish testaceous. Length 

 5J — 6 mm. 



This species is very distinct from any of the Cossonideous beetles contained 

 in the Sydney collections, but as the group is one which has received but 

 little attention from Australian entomologists, I cannot speak with any 

 degree of certainty as to its allies. In fades it is not unlike Cossonns basalis, 

 Pasc, described from New Guinea, except that is rather more convex, but its 

 sculpture is very different. 



ANTHKIBIDiE. 

 Litocerus Balli, sp. nov. 



Elongate, moderately convex, dull ferruginous, densely clothed with fine 

 ashy gray pubescence ; prothorax with two longitudinal pieeous bands, one 

 on each side, the basal carina strongly raised and sinuous near the margins; 

 elytra finely punctate-striate, with a slightly raised fuscous spot on each 

 side near the base, and a series of irregular fuscous streaks behind the 

 middle, the apex inclining to brownish yellow. 



Head inclining to fuscous between the eyes ; rostrum moderately robust, 

 narrowed anteriorly, with a distinct median line ; eyes large and prominent, 

 regularly oval, and approximating in front. Antenna? moderately long, 

 slender, furruginous ; the last three joints slightly thickened, the middle or 

 penultimate one being somewhat shorter than the others. Prothorax in 

 front a little wider than the head, widening for rather more than two-thirds 

 of its length, then narrowed to the base ; the anterior margin straight, slightly 

 thickened ; the transverse carina well separated from the base, straight in 

 the middle, sinuate on either side. Scutellum extremely small, finely 

 pubescent. Elytra about three times as long as the prothorax, nearly 

 parallel-sided, rather finely punctate striate, a short stria at the base, next 

 the suture, which is abbreviated long before the middle, the interstices 

 rather broad. Underside and legs closely covered with ashy gray pubescence. 

 Length 12^ mm. ; greatest width 5 mm. 



A distinct species, unlike anything known to me. It is dedicated to Lieut. 

 , H. L. Ball, the discoverer of Lord Howe Island.
