less conspicuous insects, not ordinarily seen in numbers in the 

 cane-fields, the species varying very much according to locality, but 

 all attracted by the sweet excretions of the leaf-hopper. 



Species of Sarcophaga, Eristalis punctulatus, Volncella ohcsa, 

 the little cockroach, Phyllodromia hicroglypJiica, and common 

 Hciniptcra being the most conspicuous. Possil)ly with these 

 should be included the three Elaleri(lai\ Aeolus cinnamoineus in 

 many localities, and two native species, Eopcnthcs Kouac and 

 Jtodacnus sp? only in proximity to the ijative forests. Feeding on 

 the black fungus may be found certain minute Psocidae, one ex- 

 tremely small and pretty species being in countless numbers on al- 

 niost all plantations. None of the insects in this last section can 

 be considered in any way beneficial or injurious, excepting that 

 they may, and ])robably do, carry and spread the spores of nox- 

 ious fungi. 



IMPOSSIBILITY OF EMPLOYING ARTIFICIAL MEANS TO DESTROY 

 LEAF-IIOPPER. 



13. When one is acquainted with the habits, of the leaf-hopper, 

 its mode of feeding, the love of concealment shown by the larger 

 number of individuals, the hidden eggs, present in numbers at all 

 reasons ; and at the same time accpiainted with the mode of growth 

 of a thrifty cane-field, the question of insecticides as a mode of 

 repression cannot for a moment be entertained. 



As the leaf-hopper is attracted with great facility to strong 

 lights, I thought it possible that until imported natural enemies 

 were available these nu'ght be employed, as unquestionably myr- 

 iads might be attracted and caught in receptacles containing sticky 

 or oily fluids, placed just beneath the lights, on still dark nights. 

 I am told by managers of plantations, who are naturally the best 

 judges, that on account of the expense involved, such a plan is im- 

 possible.
