the extremity of the body, from which the coveted fluid is emit- 

 ted. This organ is distinctly 3-segmented. The small terminal 

 segment was of a crimson color; the penultmate segment black, 

 with a broad white median band; and the basal segment (of the 

 extensile part) white. When the insect is undisturbed this or- 

 gan is withdrawn into the long conical segment which apparent- 

 ly terminates the body, but is extruded immediately upon appli- 

 cation by the attendant ants." 



Green calls this form a Ccntrotus, Buckton naming it C. nccfaris 

 but'apparently it does not belong to that genus. 



In Hawaii, although ants often kill considerable numbers of 

 }oun:g Pcrkiiisiclla, on the other hand they appear to protect 

 them from their enemies, at a later stage, so that they (the 

 ants) can enjoy the honey dew excreted from the hoppers. 



It may be noted that Coding states that species of Tragopa 

 (a Membracid) live in the ground in the nests of the ants, while 

 a curious new I^ f ^i e, (Mynnccophynic formiccticola) was discov- 

 ered under a stone in an ants' nest by Mr. Perkins. Further, it 

 has been known, and occasionally noted, that t'he remarkable 

 Tetigoniophanous Fulgoroid Tdigomctra lacfa is found in sim- 

 ilar situations to Tragopa.
