 species " Spina scutelli brevi, cylindrica, Integra, obtusa," he had 

 not previously described or referred to it in his ' Hemiptera 

 Fabriciana,' and it therefore seemed probable that he had not 

 exnmined the species when in London. I have, however, now- 

 examined the unique tvjie in the Banksiau collection, and find tiie
