228 LONGICORNIA. [ Molorchus. 
MOLORCHUS, Fabricius. 
The members of this genus have the anterior coxal cavities broadly 
closed, and the elytra strongly abbreviated ; the head is about as broad 
as the thorax, which is longer than broad, and uneven; the abdomen 
has the first segment a little longer than the second; the legs and 
antennie are very long, the latter being either 11-jointed in both sexes, 
or 12-jointed in the male; the femora are strongly clavate and petiolate; 
the genus contains fifteen species, of which four are found in Europe, 
and the remainder have been described from North America, Cuba, 
Hongkong, &c.; one has occurred in the Australian district; the larva 
of M. dimidiatus (M. minor) has been described by Schiddte (Pars ix. 
414); it much resembles those of the allied genera, being sparingly 
pubescent, and broadest in front and narrowed behind; the ocelli appear 
to be wanting, and the antenne are a little longer than is usually the 
case ; this larva feeds in dead and decaying boughs of pine and fir. 
I. Elytra with an oblique white line on each behind 
middle; antennz in male 12-jointed. . . . M. minor, L. 
Il. Elytra unicolorous ; antenne 11 jointed it in both sexes M, UMBELLATARUM, L. 
M. minor, L. (dimidiatus, F.; Cenoptera minor, Thoms.). Black, 
rather sparingly pilose, somewhat shining, with the elytra ferruginous- 
brown or reddish, furnished on each side near apex with an oblique 
raised white line; antenne and legs ferruginous, the femora being 
clavate with the elavate part blackish; thorax longer than broad, thickly 
and finely punctured, with a row of five smooth tubercles a little before 
base ; elytra very short, sparingly punctured, with shoulders produced 
and well marked; legs very long. L. 6—9 mm. 
Male with the antenne 12-jointed, almost twice as long as body. 
Female with the antennez 11-jointed, a little shorter than body. 
On Umbellifere, hawthorn blossom, &c.; also in dead hedges and on palings; 
very rare; W indsor and Hertford (Stephens); Wandsworth (Saunders) ; Headley 
Lane, Esher (Gore); Esher (J. Gray); Shiere (Capron); found on flowers near fir 
trees at Black Park, and also at Mickleham (S. Stevens). 
M. umbellatarum, L. (minimus, Scop.; s.g. Conchopterus, Fairm.). 
Allied to the preceding, but smaller and narrower, and easily distin- 
guished by having the elytra of a unicolorous testaceous-brown colour, 
without oblique “white lines near apex; the thorax is more coarsely 
punctured, with a central line nearly smooth and without distinct 
tubercles at base; the elytra are shorter in proportion, and the legs are 
more gradually clavate; in the male the antenne are much longer, and 
in the female much shorter than the body. L. 6-9 mm. 
In dead hedges; occasionally found on flowers, especially hawthorn blossom ; 
very local and, as a rule, rare, but sometimes not uncommon where it occurs; 
Darenth Wood and Whitstable (Champion and others) ; Coombe Wood; Sydenham 
and Horsell (Power); Shiere, near Guildford (Capron); it has not occurred, 
apparently, out of the London district.
