THE JASSOIDEA RELATED TO THE STENOCOTIDiE WITH 

 SPECIAL REFERENCE TO MALAYAN SPECIES

In another paper 1 I presented a study of some remarkable, 

 isolated, largely palseotropical jassoid types, which were brought 

 together in the family Stenocotidae sens. lat. A study of ex- 

 tensive, recently collected Malayan material, Australian material 

 kindly furnished by Mr. F. Muir and Dr. J. F. Illingworth, 

 Japanese material obtained from Prof. S. Matsumura, Indian 

 material from the Zoological Survey of India, and Sumatran 

 material from Mr. J'. B. Corporaal strengthens the general 

 conclusions reached in that paper, and makes possible the pre- 

 sentation of much more confirmative evidence and a better 

 arrangement of the families and genera involved. This later and 

 more extended study convinces me that the groups formerly 

 proposed are natural ones, and that they are better distinguished 

 and of higher grade than was formerly supposed. 



Distant 2 refers to the above paper, and dismisses the whole 

 matter by saying that he does "not propose to follow" the 

 removal of Signoretia from the Tettigoniellidse. 3 He does not 

 explain how a genus having ocelli placed contiguous to the ante- 

 rior border of the head can possibly be placed in the Tettigo- 

 niellidse as that family is currently characterized — even in the 

 Errhomenellini, in which the ocelli are located farther forward 

 than in normal tettigoniellids, but still on the disk of the vertex 

 and remote from the frontal suture; nor can he mention any 

 true tettigoniellid in which the ocelli are visible in facial view, 

 as they are in all of the insects placed in Stenocotidae sens. lat. 

 in the paper mentioned.
