(Plate 174.) 

 Though it is a common sight to^iind swarms of small bugs like species 

 of Idiocenis, Helopeltis, Caloco^is, Emfoasca and other minute forms, 

 I have not seen bugs of fairly large size as the ones I am referring to in 

 this note appearing in such numbers, and it is to know from you 

 whether any one else has noted these insects in such numbers that I 

 speak about these to-day. 



The three Fulgorid bugs arc : — 



1. Ftdgora ddesserti, Guer. Species of this genus of large beautiful 

 bugs ate regarded as more or less rarities. In October 1917, while out 

 on a collecting trip to the foot of the Nilgiris, I accidentally came across 

 this insect in large numbers. About twenty or thirty of them were 

 always found perched on the bark of the stem of huge trees, chiefly 

 Ailanthus excelsa and Terminalia belerica. The peculiar colouration of 

 the tegmina and the head protects them easily and it is very difficult 

 to find them on these tree stems even when they are in numbers. Once 

 disturbed, all fly away and it was found rather difficult to catch them 

 unless very carefully netted. 



2. The other bug, also a Fulgorid, is Kalidasa sanyiiinalis, Westw. 

 (fig. 91 of Dist. Vol. III). This is a smaller fprm and has more or less 

 sanguineous colour. Numbers of this bug were also found always in 

 the same situations as the Fulgora. (Plate 174, fig. 1.) 



The same thing — these two bugs found in company — was observed 

 later on in Ganjam. In this case the species of Fulgora was' F. cande- 

 laria, Linn. (fig. 82 of Distant, Vol. III). (Plate 174. fig. 2.) 



3. The third one is a species of Ricania — those bugs which have 

 fairly large dark wings with pale white transparent blotches on them. 

 The species concerned here is, U. bicolorata. (PL 174, fig. 3.) In the 

 months of April and May this bug is found in thousands on almost 

 every plant along the mountain railway line running from the foot 

 of the Ghats up to Hillgrove or Coonoor. I believe Mr. Dutt has seen 

 this when he came down to Madras last time.
