The specimen from which this description is taken is in the Linnean 

 cabinet, and has a ticket attached to it with the name "forjicata" in Lin- 

 naeus's handwriting. It is distinct from the specimen in the British Museum, 

 described by Dr. Leach as L.forjicatus, as the labium in the Linnean spe- 

 cimen is smooth and without punctures, while the labium in Leach's species 

 is covered with impressed dots. It differs also in the entire absence of sub- 

 femoral spines, and in the equidistant arrangement of the labial teeth. There 

 is a specimen in the British Museum with the name L. " losvilabrum^'' attached 

 to it, in Dr. Leach's handwriting, which, from the small number of ocelli, 

 fifteen on each side, the hairiness of its legs, and the indistinctness of the joints 

 of the antennae, I am satisfied is only the young of this, or a closely allied spe- 

 cies. The very young Lithobii have fewer ocelli and teeth than the adult.

There is only a single specimen of this species in Dr. Leach's cabinet which 

 at all answers to the description he has given. I am strongly inclined to suspect 

 that some oversight was committed by Leach in the description he has given 

 of this species, the labium of which he describes as " toto profundi impresso 

 punctato." This character by no means agrees with the specimen, which has 

 only the anterior portion of the labium deeply punctured. I suspect that he 

 derived this character in part from the specimen of L. variegatus that was
