and which possess 19 antennal joints. They have however a 

 much longer tibial spur, measuring "86. " 



Mr. TuTT said he considered that Lepidopterists were under 

 great obligation to Dr. Chapman for the care he had taken in 

 working out what was possibly the most difficult group of the 

 most difficult family of Lepidoptera. The separation of 

 Bacotia sepium and of Proutia hetulina from the genus Fimnea 

 had been thoroughly substantiated by Dr. Chapman's careful 

 investigations ; and it was clear from the matei-ial exhibited 

 that he had also made good headway in explaining the nature 

 of the constituent elements still remaining in the genus Fumea. 

 He trusted, at any rate, that the combined efforts of those 

 who were now at work on this group of the Psychids would 

 have the result of clearing up some of the difficulties that had 

 hitherto surrounded these insects, difficulties so great that 

 species belonging to different sub-families had been united in 

 the same genus. 



Mr. Malcolm Burr called attention to Dr. Sharp's paper 

 on " The modification and attitude of Idolimi diabolicum," 

 recently published in the " Proceedings of the Cambridge 

 Philosophical Society " (Vol. X, Part iii.). He exhibited the 

 plate, drawn after nature by Mr. Muir, which illustrates the 

 paper, pointing out that no drawing of this kiud showing a 

 Mantid in its natural colours simulating the petals of a flower, 

 had hitherto been published. He also exhibited species of 

 Mantodea of various genera, to show the different modifications 

 by means of which insects of this group ai'e made to resemble 

 leaves and flowers.
