L. quadra will form a second division in this Genus, since 

 the second joint of the palpus is as long as the first, and curved 

 upward : Bomhyx pulchella and ruhricoUis Fab., with some others, 

 are included by tliat author and Latreille in the Genus Lithosia, 

 which has occasioned the latter to state that the palpi are three- 

 jointed, whereas Fabricias has described them as biarticulate : 

 after dissecting several specimens of our Genus, and examining 

 them most carefully, I can discover only two joints ; B. pulchella 

 and ruhricoUis, having three distinct joints in the palpi, must 

 therefore be constituted into a new Genus. 



The plant figured is Allsma Plantago (Great Water Plantain) 

 var. lanceolata.
