46 HETEROMERA, | 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. 
ZILORA, Mulsant, 
This genus contains three species, one from North America, and two 
which are found in Europe; the single British species is contined to 
Scotland, and was added to our list by Dr. Sharp and Dr. Buchanan 
White in 1871; it is closely allied to XYylta, from which it differs in 
its coarser punctuation, striated elytra, and also in the fact that the third 
joint of the antennz is shorter than the fourth ; the intermediate coxe, 
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 tibie. 
Z. ferruginea, Payk. (sericea, Sturm; obsewra, 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, antennze 
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 striz, 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 Braemar, in June, 1871. 
HYPULUS, 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 antenne 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 unmarvined ; 
the mesosternum is as long as the intermediate cox ; the elytra are not 
striated ; the legs are rather long and the penultimate joint of the tarsi
