NOTICES OF CERTAIN FULGOROIDEA, II: THE GENUS 



TROBOLOPHYA

SIX TEXT FIGURES 



In 1913, Melichar l described a new genus, Trobolophya, of 

 the family Dictyopharidas, based upon a single specimen col- 

 lected in Java by Jacobson. Just before this I had sent to 

 Melichar a Philippine representative of the same genus, which 

 he referred to as being the same as the Javan species. 2 After 

 1913 I discovered that this genus is widely and commonly dis- 

 tributed in the Philippines in several species, and that it occurs 

 in western Malaysia as far north as Penang Island, Straits 

 Settlements. In making a careful study of the accumulated 

 material, it appears that the Javan species is quite distinct from 

 any known Philippine form. 



It is hard to explain why so 

 generally distributed a genus, 

 with some of the species very 

 common, remained unknown to 

 science until 1913, unless it be 

 due to the fact that the species 

 are montane and arboreal ; though 

 this is only in so far as my ex- 

 perience goes. 



External anatomical features in 

 this genus are difficult to appraise 

 at their true comparative value 

 since, as in many Derbidse and 

 other fulgorids, high and thin 

 margins may incline one way or the other in drying, and partial 

 collapse of certain areas may occur. It is thus very important 

 to have ample series of specimens for study, and in most cases 

 I have obtained these. The genitalia will, as in other Fulgoro- 

 idea, undoubtedly furnish characters of great diagnostic value, 

 but in this case would require dissection and special preparation
