NOTICES OF CERTAIN FULGOROIBEA, II: THE GENUS 
TROBOLOPHYA

In 1913, Melichar 1 described a new genus, Trobolophya, of 
the family Bietyopharidse, 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 Derbid® 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
