223 LONGICORNIA. {Molorclius. 



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 

 antennas are very long, the latter being either 11-jointed in both sexes, 

 or 12-jointed in the male; the femora are strongly clavate and petiolale; 

 the genus contains fifteen species, of which four are found in Europe, 

 and the remainder have been described from North America, Cuba, 

 Ilougkong, &c. ; one has occurred in the Australian district; the larva 

 of M. dimidiatus (M. minor) has been described by Schiodte (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 antennae are a little longer than is usually the 

 case; this laiva feeds in dead and decaying boughs of pine and fir. 



I. Elytra with an oblique wliite line on each behind 



middle ; antenna) in male 12-joiuted M. MINOR, L. 



II. Elytra unicolorous ; antennae 11-jointed in both sexes M. TTMBELLATABUM, L. 



UK. minor, L. (dimidiatus, F. ; Ctsnoptera minor, Thorns.). 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 ; antennae and legs ferruginous, the femora being 

 clavate with the clavate part blackish; thorax longer than broad, thickly 

 and finely punctured, with a row of five smooth tubercles a little be lore 

 base ; elytra very short, sparingly punctured, with shoulders produced 

 and well marked ; legs very long. L. 6-9 mm. 



Male with the antennae 12-jointed, almost twice as long as body. 



Female with the antenna? 11-jointed, a little shorter than body. 



On Umbrllifcrse, hawthorn blossom, &c. ; also in dead hedges and on paling's ; 

 very rare ; Windsor and Hertford (Stephens^ ; Waudsworth (Saunders) ; H<>;i<llry 

 Laue, Esber (Gore) ; Esher (J. Gray) ; Shiere (Caprou); found on flowers near fir 

 trees at Black Park, and also at Mickleham (S. Stevens). 



1*1. umbellatarum, L. (minimus, Scop.; s.g. Conchopterus, Fainn.). 

 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 antenna? 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; 

 Daren th Wood and Whitstiible (Champion and others); Coombe Wood ; Sydrnlmtu 

 nud Horsell (Power); Shiere, near Guildford (Capron) ; it has not occurred, 

 apparently, out of the London district.
