each side of llu- i-Dstnil canal. Tlic niiddli' and hind tibi;e 

 aw medially an{|;ulatc externally and prolonj^i-d at the outer 

 extremity, the former most distinctl^^ so that their structure 

 is somewhat similar to that of J'se/j/mhix. 



The <;enus is instituted for the more systematic location 

 of Onda murina (80 1), whieii uow becomes Kentraulax 

 murina. 



Getacalles favosus, sp. n. 



Convex, suhoblong, opaque, rouj^h ; densely covered with 

 varie^'ated, small, (leprc>ssed, and some elongated upright 

 squamie, yellowish brown or testaceous, the darker colour 

 ])redoniinates, the li-^hter form crests and cover the sutun; 

 of the elytra from behind the middle to the apex ; antenna; 

 and tarsi ferrugi neons. 



Jiosti'tnn moderately arched, parallel, thick, quite as long 

 as thorax, constricted near the eyes, closely punctate, covered 

 with rufo-fuscous scales almost to its apex. Thorax in front 

 only about half the width of the basal portion, depressed ami 

 obtusely prominent, but not distinctly crested there ; the 

 larger basal part with two small pale crests near the front 

 and two near the middle further apart, its sides rough, with 

 pale outstanding scjuama}. Scutelluni very distinct, greyish. 

 Ehjira «ith thick humeral angles projecting beyond the 

 base of the thorax ; with coarse irregular j)unctures or fovea; 

 and irregularly formed, slightly raised intervals, so as to 

 apjicar soniewhat favose ; they bear about twenty more or 

 less evident crests or nodosities, the most conspicuous being 

 situated behind the middle. Leys roughly squamose. 



Underside scjuamose, pale brown, the sides of the terminal 

 segments blackish. 



In Tychanus, the nearest ally, tlie rostral canal extends to 

 the middle of the intermediate coxa;, where it is deep or 

 cavernous ; but in this species the hiud j)art has a frontal 

 slope, so that the tip of the rostrum cannot penetrate beluw 

 the margin of the mesosternal process. The ventral segments 

 are on two distinct planes, the terminal three being sunk 

 below the level of the epijjleura ; the basal segment is more 

 than double the length of the second in the middle, its hiiul 

 suture is much sinuate, nearly vertical, and as densely 

 squamose as its upper surface ; third and fourth moderately 

 short. 



The scape is slender, tiexuous, and a little inerassate 

 towards the extremity. The funiculus is longer : secoml 

 joint more slender than, but almost as long as, the first ;
