 on board a yacht at Dartmouth.

This geiuis contains more than fifty species, Avliicli arevery widely 

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

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

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

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

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

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



Westwood (Classific. i. 149) describes the larva of Lct;mopMceus ater 

 (Cucuius Spartil) 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) deseriljes and figures the larva 

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

 ventricose, or rather fusiform, being broadest in middle and narrowed 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 larva) of Hylesinus rhodu- 

 dacfyltis, and that of L. demcdidis on the larva) of Tomicus Inspmus.
