1878.] J. Wood-Mason — New specimen of Thaumantis. 177 



A few, hitherto apparently unknown, Sanskrit verses in praise of con- 

 tentment are added, which are universally attributed to Kalidasa in that 

 part of the country. 



In conclusion, Mr. Grierson promises to communicate at some future 

 time similar legendary accounts of other famous heroes and heroines of 

 Mithila. 



The paper will be published in the Journal, Part I. 



2. Description of a 7iew Lepidopterous Insect helonging to tlie Genus 

 Thaumantis. — By J. Wood-Mason. 



(Abstract.) 



This paper contains additional remarks on the fine butterfly collected 

 by Mr. Ossian Limborg in the Taoo mountains of Tenasserim and described 

 in the ' Proceedings' for July, 1877, p. 163. In the collection made by 

 Mr. Limborg were 225 other species of Lepidoptera, from fifty to sixty of 

 which are undescribed. 



Both the specimens of the new species, Thaumantis Louisa, are males, 

 and each is furnished with a tuft of erectile hairs on the hind wing. It is 

 suggested that these may be odoriferous organs, like similar tufts on the 

 different parts of the body in the males of some Brazilian butterflies. 



The paper is accompanied by a plate from a characteristic coloured 

 drawing by Professor Westwood. 



The paper will be published in the Journal, Part II. 



3. On the Diurnal Variations of Mainf all-frequency at Calcutta. — By 

 H. F. Blanfoed, F. G. S., F. Z. S. 



(Abstract.) 



A table is given of the occurrence of rain at each hour of the day in 

 each month of the year, merely the fact of occurrence and not the amount 

 of rainfall being noted. It is shewn that the proportion of rain falling at 

 different hours of the day varies with the season. In the summer monsoon 

 the smallest rainfall is at midnight, the greatest about 2 p. m., the time of 

 maximum temperature. In the dry and hot season, February to May, the 

 maximum rainfall is between 6 and 8 p.m. owing to the evening storms. 

 In October and November the rainfall appears to have a similar distribu- 

 tion to that prevailing in the rains. In December, the recorded falls are too 

 few in number to lead to any conclusion, but in January, the period of the 

 winter rains, the maximum rainfall appears to coincide with the period of 

 minimum temperature in the early morning. 



The paper will be published in the Journal, Part II.
