112 R. Takaliatlu 



of the macropterous form, since a specimnn of this form in my collection is provided 

 with only 3 sensoria on the 3rd anfennal joint. In the brachypteroiis form of 

 Myzocallis kurieola (Mats.) the ocelli are as well developed as are tliosc of the macro- 

 pterous form. S. cdficolaifi is quite closely allied to S. celti Das (Apliididae of Fnr- 

 mosa-1, p. 74 and ibid-2, p. 131) and it is almost impossible to distinguish them by 

 structural characters, but the former species difleis from the latter in the following 

 characters: 



( 1 ) BrachypterouR forms appear very commonly in almost every genera- 

 tion. 



( 2 ) Body more covered witli wax.

 small transversely narrowed sensoria, which are very sliglitly protuberant, irregu- 

 larly scattered over the entire length; the 4th almost as stout as the front tibia, pro- 

 vided witli about 25 oval sensoria, which are ratlier small and not protuberant, 

 scattered ever tlie whole lengtli; the 5th with about 15 similar sensoria and an apical 

 small circular one; the 6th with a few similar ones on the basal part; the relative
