Clerina. | SERRICORNIA. 169 
IT. Antenne with a distinct and abrupt short club; last 
joint of maxillary palpi a little broader than the pre- 
ceding, of labial palpi securiform. . . . . . . . (TRICHODES, Herbst.) 
OPILO, Laitreille. 
The species belonging to this genus are about forty in number, and 
are very widely distributed, especially in the tropics; four are found in 
Europe, of which one only occurs in Britain; its larva has been fully 
described and figured by Waterhouse (Trans. Ent. Soc. Lond., No. 1, 
pl. 5, fig. 1), and is also figured by Westwood (Classification, i. p. 262, 
fig. 29, 12); it is of a pink colour above and pale beneath, and about 
half an inch long, slightly narrowed in front and widened behind, 
with the abdomen terminating in two corneous prominences ; the body 
is covered with rufescent hairs; according to Chapuis and Candéze the 
meso- and metathorax and the six first abdominal segments bear four 
spots of a bright red colour on each; these larvee, according to West- 
wood, are found in rotten white-thorn wood, and also in dry and decaying 
willows, where they feed on the larve of Anobiwm and other insects ; 
the perfect insects are found under the bark; Latreille states that the 
larve are also met with in houses in old wood. 
O. mollis, L. Elongate, rather depressed, with the elytra slightly 
widened behind in the male and more plainly in the female, clothed 
with long pale pilose hairs; colour fuscous with an oblique spot at 
shoulders of elytra (which is often divided, forming a spot at shoulder 
and a longitudinal spot near suture between base and middle), a fascia 
on each behind middle not reaching suture, and the apex, yellow ; the 
head and thorax are testaceous in front, and are closely and coarsely 
sculptured ; head large, with eyes strongly granulated, antenne long, 
testaceous ; thorax longer than broad, contracted behind, with a tubercle 
on each side in front ; elytra long, with rows of strong punctures, 
interstices with rows of distinct but small punctures ; legs testaceous, 
with femora broadly ringed with a more or less pronounced pitehy 
colour, apex and base light. L. 73-10 mm. 
In rotten wood and by beating dead hedges; occasionally at sugar; very local, 
and, as a rule, rare; Kew, Richmond Park, Putney, Coombe Wood, Forest Hill, 
Darenth Wood, Chatham, Sheerness, Whitstable, Leytonstone, Brockley, Croydon, 
Beckenham, Loughton, Barnes, Esher, Tonbridge ; Windsor ; Hastings; Llan- 
gollen; it appears to be chiefly confined to the London district, in which it is gene- 
rally distributed, and sometimes not uncommon; it is so conspicuous an insect that 
it can hardly have been passed over in other localities. 
TARSOSTENUS, Spinola. 
In the Munich eatalogue only three species are referred to as 
belonging to this genus, but the number has since been largely added 
to, and Mr. Gorham inferms me that it is of almost universal distribu-
