46 HETEHOMERA.. \Xylita. 



third from base, and thence rather strongly contracted to base, the sides 

 forming an angle ; scutellum transverse ; elytra as broad at base as 

 thorax, subparallel, gradually and slightly narrowed at apex ; legs 

 variable in colour. L. 6-9 mm. 



Under bark and in old trees ; rare ; found only in Scotland, Highlands, Tay, 

 Dee and Moray districts, Aviemore, Rannoch, &c, 



ZXIiORA, Mulsant, 



This genus contains three species, one from North America, and two 

 which are found in Europe ; the single British species is confined to 

 Scotland, and was added to our list by Dr. Sharp and Dr. Buchanan 

 White in 1871 ; it is closely allied to Xylita, from which it differs in 

 its coarser punctitation, striated elytra, and also in the fact that the third 

 joint of the antennae is shorter than the fourth ; the intermediate coxae, 

 moreover, are not contiguous ; the thorax has the sides acutely margined, 

 strongly narrowed in front, and is deeply impressed on each side at 

 base ; the last joint of the maxillary palpi is very broad and securiform; 

 the tibial spurs are small but distinct, and the tarsi are rather shorter 

 than the tibiae. 



Z. ferrugrinea, Payk. (sericea, Sturm ; obsctira, F.). Elongate, 

 subparallel, moderately convex, clothed with rather coarse greyish or 

 greyish-yellow pubescence ; colour reddish-brown, or reddish-castaneous, 

 with the shoulders and part of head and thorax sometimes a little 

 lighter ; head subtriangular, uneven, rather coarsely sculptured, antennae 

 rather robust, ferruginous ; thorax about as long as broad at base, 

 strongly narrowed in front, broadest behind middle and thence a little 

 narrowed to base, with traces of a central furrow, and with a strong im- 

 pression on each side at base, rather strongly punctured, the punctuation 

 being rather sparing on disc ; elytra a little broader at base than thorax, 

 subparallel, with more or less distinct striae, coarsely and somewhat 

 rugosely punctured ; legs ferruginous or reddish - testaceous. L. 6-7 

 mm. 



In Polyporus abietinus on dead Scotch fir ; also under bark of the same tree ; 

 extremely local ; Scotland, Dee and Moray districts ; it was first discovered in Britain 

 by Dr. Sharp and Dr. Buchanan White at Braeinar, in June, 1871. 



HVPUZiUS, Paykull. 



Three species are contained in this genus, of which two occur in Europe 

 and one in North America ; they are rather small insects, with the elytra 

 banded with yellow ; the antennae are comparatively short and robust 

 with the second joint short and the third equal to, or shorter than, the 

 fourth ; the thorax is about as long as broad, with sides unmar^'ined ; 

 the mesosternum is as long as the intermediate coxae ; the elytra are not 

 striated ; the legs are rather long and the penultimate joint of the tarw
