40 HETEROMERA, [Serropalpus. 
(SERROPALPUWS, Hellenius.) 
This genus contains four species, two of which are found in Chih, 
and the other two, which appear now to be classed together, in Europe ; 
S. barbatus (striatus) also oceurs in North America, where it has been 
described as S, obsoletus, Hald. The following are the chief characteristies 
of the genus :—Head vertical, eyes large, coarsely granulate, labrum small, 
mandibles short and stout ; antenne jong, not shorter than half the body, 
1]-jointed, with the second joint the smallest ; maxillary palpi serrate, 
large, with the fourth joint lunate; thorax narrower at apex than at 
base, with the posterior angles acute and the sides not margined in 
front ; scutellum truncate at apex ; prosternum short before anterior coxe; 
mesosternum as long as intermediate cox; elytra with more or less 
distinct striz ; posterior legs long, with the tarsi longer than the 
tibie. 
S. barbatus, Schall. (striatus, Hellen.). Elongate, parallel-sided, 
convex, dull, thickly clothed with pale pubescence, entirely brown with 
the antennee and legs testaceous ; thorax narrowed in front, very closely 
punctured ; scutellum truncate at apex; elytra long, with more or less 
distinct striz, interstices rugosely punctured. L, 12-16 mm. 
Under bark of spruce fir; found in Norway and Sweden, France, Prussia, Austria, 
and Bavaria, and perhaps a native of Britain; only two specimens have, however, been 
hitherto recorded, one taken in a warehouse in Leices'er by Mr. I. Plant (v. Ent. 
Ann. 1872, 76), and another recorded by Mr. Blundell of Luton in 1882 (Entomologist, 
xv. 286), as probably taken near Newmarket. Mr. Blundell kindly wrote to me 
with regard to the latter capture ; the insect may possibly have been indigenous, but 
in all probability was an imported specimen, as it is hardly possible that so con- 
spicuous a species would have escaped observation, if it had established itself in the 
middle of England, and no further specimens have occurred. 
MELANDERYA, F. 
This, the typical species of the family, contains about seven species, 
which are confined to Europe, Northern Asia, and North America ; three 
are found in Europe, of which two occur in Britain, one of these being 
extremely rare; they are large or moderately large dark-coloured insects, 
with the thorax narrowed in front and margined behind at sides ; the 
antenne are rather short but slender; the elytra are long, subparallel, 
distinctly striated; the legs are somewhat elongate, but moderately 
stout, and the anterior trochantin is conspicuous; the mesosternum is 
much shorter than the intermediate coxe, and the penultimate tarsal 
joint is slightly bilobed ; the upper surface is very finely pubescent and 
shining. : 
The larva and pupa of M. caraboides are described and figured by Schiddte 
(xi. pp. 565, 586, t. xvii. 1 and 15); the larva is cylindrical, about six times longer 
than broad, membranous, with the head and legs alone corneons, whitish with the 
head and legs yellowish; the head is very large, and the prothorax cordate and
