PROCEEDINGS OF THE THIRD EXTOMOLOGICAL MEETING 1033 



Fidyora candelaria does not seem to be a very common species as a Mr. Fletcher. 

 Tule. I have not come across it myself in India although I found it in 

 Hongkong twenty years ago. Did you observe any special function of j^ Ramakrishns.

No. 



Fulgorids are known to transmit fungal or bacterial diseases to plants. Mr. Beeson. 

 Work is being done in the sandalwood areas on the spike disease of 

 sandal in this connection. 



Another point of interest about these Fulgorid bugs is their supposed Mr. Fletcher. 

 luminosity. Fidgora candelaria was so called because it was supposed 

 to be luminous. I think it was Madame Merian in Surinam about two 

 hundi-ed years ago who recorded that some of these bugs were found 

 to be luminous when the box containing them was opened in the dark, 

 but since then no authentic corroboration of this statement seems to 

 have been obtained. I made inquiries at Hongkong but was unable 

 to obtain any confirmation of this supposed luminosity. The luminosity. 

 if it does really occur, may be the result of bacterial disease and not 

 to the action of photogenic organs. 



84.— EUMASTACIN.f; FROM SOUTH INDIA. 



By T. V. Ram.\kri.shna Ayyar, B.A., F.E.S., F.Z.S., Acling Government 

 Entomologist, Madras. 



(Plate 175.) 

 In exhibiting herewith some specimens of these curious insects 

 collected from South India I would add a few remarks. 



The group Eumastacinse is, as most of 3'ou know, a sub-family of 

 the well-known Orthopterous family Acridiidae. The insects included 

 in this sub-family are all very curious and abnormal in structure as 

 compared with other grasshoppers {see figure). 



The striking features of these insects are the extreme shortness of 

 the antennae, the curious posture and structure of the wings (some are 

 apterous) and the peculiar leaflike projected formation of the prothorax 

 in some forms. Almost all of them are comparatively small in size, 

 ranging from half an inch to not more than a couple of inches in length. 

 .Almost all the Indian species recorded are from the Hills of Burma, 

 Kashmir and South India. 



Mr. Kirby in his Fauna Volume on Acridiidw has described all the 

 forms known up to 1914. Since then Candido Bolivar has described 

 three new South Indian forms, from some material we sent from Madras,
