688 COLEOPTERA 



reddish ; most of the pubescence is greyish, and not very obvious, but 

 whitish hairs form a strongly flexuous fascia on the middle; a spot on each 

 midway between it and the apex, another irregularly formed one on the 

 shoulder, and an abbreviated sutural line behind. Legs reddish. 



Antennae stout, longer than thorax, their two basal joints reddish, the 

 others obscure-brown ; first joint stout and bent ; second much shorter 

 and more slender ; joints 3-8 rather stout, so formed as to be serrate ; 

 ninth and tenth large, sub-triangular, but little dilated inwardly ; eleventh 

 oblong-oval. 



The chief peculiarity of the species consists in the unusually robust 

 joints (3-8) forming the stalk, and the rather short, oblong rather than 

 triangular, ninth and tenth joints.

Nov. gen. 



Allied to Anobium. Antenna elongate, 1 1 -articulate ; basal joint 

 stout, strongly flexuous ; second stout, larger than the following one ; 

 third smaller, rather longer than broad ; fourth transverse ; fifth large, 

 sub-triangular, a little prolonged anteriorly ; sixth small, cylindric ; 

 seventh similar to fifth ; eighth narrow, cylindrical ; ninth longer than 

 seventh, less produced inwardly ; tenth still less dilated inwardly ; 

 eleventh rather longer but much narrower than tenth. Terminal joints 

 of the palpi sub-securiform. 



The structure of the antenna is peculiar ; the stalk may be said to 

 consist of two joints only, the third and fourth; the fifth and seventh are as 

 large as the ordinary terminal joints seen in Anobium, but formed more 

 on the Dorcatoma pattern, and interposed between each of these is a 

 narrow articulation united to the apical prolongation of the larger ones. 

 Slight variations occur in the relative length and breadth of these joints 

 in the different species, but in all the structure is essentially the same. 



The type is X. pullum, but the insects Nos. 620, 621, and 622 must 

 be removed from Anobium, as pointed out at page 341, and added to this 

 genus. 



1205. X. pullum, n.s. Body cylindrical; blackish, clothed 

 with small dark-grey hairs ; legs piceous, the knees and tarsi somewhat 

 rufescent; the enlarged antennal joints black, finely sculptured and 

 pubescent ; the smaller ones testaceous-brown, and rather glossy. 



Head finely and densely sculptured. Prothorax about as long as 

 broad, sub-carinated behind the middle, its sculpture dense, consisting of 

 punctures and minute granular elevations; the sides are covered with 

 pale-grey hairs. Scutellum distinct, dull. Elytra broader than thorax, 

 parallel, obtusely rounded at the apex, punctate-striate, with an additional, 

 rather long, scutellar stria on each; interstices rugulose. Legs stout, 

 pubescent and finely sculptured ; tarsi stout, basal joint longest, fourth 

 shortest ; fifth stout and moderately short ; claws small. 



The insect is rather dull. In the female the antennae are shorter, 

 with the enlarged joints scarcely prolonged at the apex,
