Broun. — Xew Genera and Species of Coleoptera. 147 



The well-developod scutellum, long unarmed femora, elongated abdomen, 

 and the structure of the rostral canal distinguish this genus from Acalles, 

 Crisius, and other cognate forms. The type is 1427, now X. triangulatus, 

 to which must be added a species, X. squatttiventris, recently discovered 

 at the Chatham Islands.

Suboblong, convex, opaque ; piceous, legs obscurely rufescent, antennae 

 and tarsi ferruginous ; squamosity dense, dark fuscous and tawny, the paler 

 scales cover most of the front part of the thorax and basal half of the elytra ; 

 the short erect setif')rm squamae form about a dozen small pale crests 

 on the posterior half of the elytra ; the suture, behind the middle, bears 

 small reddish -brown scales ; the legs are clothed with greyish and fuscous 

 coarse erect squamiforai setae. 



Rostrum stout, parallel, moderately arched, nearly a third shorter than 

 thorax, closely punctate and finely setose near the apex, thickly covered 

 with suberect short squamae from the antennae backwards. Head immersed 

 up to the eyes, glabrous and reddish underneath. Thorax rather broader 

 than long, its frontal half abruptly contracted ; it is densely squamose so 

 that its punctation is invisible, the erect scales do not form distinct crests, 

 across the basal margi i there i'3 a streak formed of sm^U som3what fiavescent 

 squamae. Scutellum greyish. Elytra with obtusely porrect shoulders, 

 a little broader at the base than the thorax, slightly wider behind, more 

 than twice its length, posterior declivity a good deal narrowed and vertical ; 

 the dorsum is a little uneven, with unequal crests, and almost striate-punctate. 



Underside distinctly but not very closely punctured, covered with 

 greyish or tawny scales, but with a dark-fuscous patch at each side of the 

 intermediate ventral segments and a quadrate spot at the apex of the 5th. 

 The metasternum is short, hardly as long as the 2nd segment. Pectoral 

 canal deep, extending as far as the middle of the intermediate coxae, and 

 quite cavernous there. 



Scape moderately slender, inserted between the middle and apex, barely 

 reaching the eye. Second joint of the funiculus as long as the basal, 

 joints 3-6 subquadrate, 6th rather broader than 3rd, 7th obconical, larger 

 than 6th. Club oblong-oval, triarticulate. 



It is larger than the type of the genus (2410), more variegated, and with 

 more definitely striate elytra. 



Length (rostrum exclusive), 4 mm. ; breadth, 2 mm.

 September, 1910, by Mr. A. O'Connor.

Nitid, rufous, club fulvescent ; sparingly clothed witli slender yet distinct 

 yellow hairs. 



Rostrum parallel, quite half the length of thorax, with a broad median 

 impression between the antennae and eyes, rather coarsely punctate, more 

 finely in front. Occiput nearly smooth. Thorax a third longer than broad, 

 gradually narrowed towards the distinct frontal constriction ; with a broad
