This genus contains more than fifty species, which are very widely 

 distributed ; it is, however, impossible to discuss their distribution with 

 any certainty, as some of them are almost cosmopolitan, and are carried 

 from one part of the world to another in grain, &c. ; thus L. pusillns is 

 described under various names from England, France, Brazil, Surinam, 

 &c. ; many, however, are found under bark, where their larvoe appear 

 to be parasitic on species of Tomicus, Hylesinus, &c. 



West wood (Classific. i. 149) describes the larva of Lcemophlceus ater 

 ( Cucujus Spartii) as long, narrow, and subdepressed, of a fleshy con- 

 sistence and white colour, except the head and terminal joint of the 

 body, which are a yellowish-brown ; the thoracic segments are semi- 

 transparent, so as to show the motion of the base of the legs from above ; 

 when disturbed, it slightly elevates the extremity of the body, which is 

 terminated by two short but rigid incurved hooks. 



Ferris (Ann. Fr. p. 618, pi. 19, 122) describes and figures the larva 

 of L. Dufouri, which has a narrow orbicular head and the abdomen 

 ventricose, or rather fusiform, being broadest in middle andnarroAved in 

 front and behind ; the eighth segment is long and narrow, and the ninth 

 short and terminated in two rather strong short hooks ; according to 

 this author the larva of L. ater preys on the larvae of Hylesinus rhodo- 

 dacfyhis, and that of L. clematidis on the larvae of Tomicus Inspinus. 



I. Forehead with a fine longitudinal line, trisinuate in 



front ; each elytron with a black spot ....... L. BIMACULATUS, Payk. 



II. Forehead without longitudinal line, truncate in 

 front ; upper surface ferruginous, rarely black. 



i. Thorax with two longitudinal lines on each side . . L. DUPLICATUS, Walil.

1. Posterior angles of thorax right angles or acute. 



A. Antennae of male as long as body ; thorax not 



rounded at sides L. PUSILLUS, Schon. 



B. Antennae of male a little more than half as long 



as body ; thorax rounded before middle . L. FERBUGUNEUS, Steph. 



2. Posterior angles of thorax obtuse. 



A. Elytra together about twice as long as broad, 

 or less, unevenly striated; colour black, rarely 



dark ferruginous L. ATEB, 01. 



B. Elytra together more than double as long as 



broad, evenly striated, colour ferruginous . . . L. CLEMATIDIS, Er. 



Xi. bimaculatus, Payk. (unifasciatus, Latr.). Depressed, very 

 shiny, bright reddish-testaceous, with a large black spot on each behind 

 middle, which nearly meet at sviture ; head large, thickly punctured, with 

 a fine longitudinal line in middle, antennae very long and slender; thorax 

 a little shorter than broad, narrowed behind, posterior angles almost
