114 FAUNA HAWAIIENSIS 



island of Oahu. This form is now considered to be a distinct species, though it is 

 extremely close to the S. American insect with which it was previously identified — as a 

 small form — by the late Mr Bates and myself. Gahan considers that L. longipennis 

 Bates is a mere synonym of L. obsoletiis. The form is widely distributed, having been 

 found in Loo Choo islands, Tahiti, the W. Indies, and Mexico.

 Mr Perkins, knowing it not to be native, procured but few examples. The species is 

 very widely diffused, having been found in Madagascar, Port Essington, Tondano, 

 Amboyna. L. bankii was described as found at the Cape of Good Hope. The 

 identification is due to an examination of the Banksian type in the collection of the 

 British Museum made by Mr Gahan. The genera Prosoplus and Micracantha are 

 considered by him to be one and the same.
