The Rhopalocera, or butterflies, have been enumerated for me by 

 Mr. W. L. Distant, to whom I am indebted for assistance in several 

 matters connected with this enquiry. He considers the number of species 

 known to be about 875. The whole number of Lepidoptera is consequent- 

 ly 4,620. 



I am also indebted to Mr. Distant for having taken the trouble of 

 approximately estimating the known Rhynchota. He finds the number 

 to be about 



Hemipteea Heteroptera, 450 



Hemiptera Homoptera, 200 



650 



Mr. R. McLachlan, to whom I applied for assistance in the order of 

 Neuroptera of which he has made a special study, considers that 350 is a 

 fair estimate. 



I have been unable to obtain any trustworthy enumeration of the 

 Diptera and Orthoptera. 



Amongst the other classes of the Arthropoda the only trustworthy 

 information I have been able to procure is from Mr. Cambridge who informs 

 me that although a large number of Indian Spiders have been collected 

 very few have been determined or described. He knows of only 108 species 

 distributed amongst the following families : 



Theraphosidae, 3 



Tetrablemmidae, 1 



Drassidae, 12 



Palpima7iidae, 1 



Agelenidae, 2 



Hersiliidae, 2 



Scytodidae, 2 



Pholcidae, 4 



Theridiidae, 10 



Phofoncididae, , 5 



Epeiridae, 16 



Gasteracan th idae, 11
