Rhizopertha. | SERRICORNIA. 201 
casks; London; Birmingham ; Scarborough, in flonr mills; Northumberland dis- 
trict; it occurs in numbers where found, and has probably been imported into must 
of our large towns, 
BOSTRICHUS, Geoffroy. 
This genus contains upwards of twenty species, of which four occur 
in Europe; the remainder are widely distributed, species having been 
described from North, Central, and South America, South Africa and 
Madagascar, and the Australian region ; the genus is therefore probably 
much more extensive than is at present known; it is closely related to 
Apate, and some authors prefer to include our single species under the 
latter genus. 
B. capucinus, L. A large and fine species, elongate, cylindrical, 
dull, very slightly pubescent ; head and thorax black, antennze pitchy, 
elytra red ; breast and base of abdomen black, the rest of the latter red; 
legs pitehy black with tarsi red ; head thickly, rugosely, and rather 
strongly punctured, eyes small, antenne short, hardly as long as head, 
with the club not strong; thorax roundish quadrangular, strongly con- 
vex, with the anterior margin impressed in middle, and with the upper 
surface strongly and rugosely punctured or granulose, the granules on the 
front half, especially at sides, forming strong tubercles; elytra scarcely 
broader than thorax, rather coarsely punctured and with traces of raised 
lines, rounded at apex; legs rather slender, tarsi apparently 4-jointed, the 
first joint being very minute, second joint longer than the last. 
L. 8-9 mm. 
In decayed trees; very rare, and does not appear to have been taken for many 
years ; Stephens gives as localities, London district, Cromer, Derbyshire, Notts, and 
Bewdley; in Dr, Power’s collection there is a specimen from E. Brown’s collection 
taken at Burton in 1867, and another from Bentley’s collection ; Mr. Dale records 
the capture of a single specimen by his father on the table-cloth in his dining-room at 
Glanvilles Wootton on July 2nd, 1854; Mr. Rye (British Beetles, p. 149, 1866) 
records a specimen as “recently taken near Highgate on a felled oak.” 
LYCTIDZ. 
This small family is usually included under the Bostrichide or 
Cissidee, but appears to be distinct from either; its chief distinguishing 
points are the large 2-jointed club of the antenne, and the elongate first 
ventral segment of the abdomen ; the anterior cox are enclosed by the 
prosternum ; the antennee are 11-jointed, and the tarsi have the first joint 
obsolete, and the last longer than the rest taken together; the family 
contains two genera, Lyctus and T'rogorylon, but Thomson also includes 
under it Dinoderus, which does not, however, agree with it in one or 
two of the generally received distinguishing characters. 
LYCTUS, Fabricius. 
This genus contains about twenty species, of which three occur in
