LXVIII. — Rhynchotal Notes. — X. Heteroptera : 

 Fam. Lygfeidse. By W. L. Distant. 



^J'nE present contribution relates to the subfamily Lygaiinaj 

 as contained in the collection of the British Museum, witb 

 a revision of Walker's determinations in this grouj). All 

 further study strengthens the o))inion that when Walker's 

 types are obtainable his species (if valid) should stand ; but 

 his descriptions are often so imperfect — as they are especially 

 in this family — that where the types are not to be found such 

 descriptions should be considered as non-existent, a course 

 not necessarily harsh when the vast synonymy already created 

 is realized and the loose location of the species is remembered.
