ELENCHUS TENUICOBNIS, KIRBY, AND ITS HOST. 

 BY EDWAKD SAUNDEES, F.L.S. 



At page 249 ante, I gave an account of the capture of a specimen 

 of U. tenuicornis, ^,'m the act of emerging from its host, an immature 

 Libumia. It was considered desirable to record at once so interesting 

 a chapter in the life-history of this rare Strepsipterous insect, and 

 there was not time to prepare an illustration. The above, much en- 

 larged, figure has been drawn from the specimens (host and parasite) 

 as captured.

THE LIFE-HISTORY OF LA3IPR0NIA CAPITELLA. 

 BY T. A. CHAPMAN, M.D., F.E.S. 



That portion of the life-history of this species that dates from 

 the opening of the currant buds in spring to the appearance of the 

 moth is well known ; the remainder, that I here propose to relate, does 

 not appear to have been previously recorded. The larva in spring 

 does occasionally so much damage by destroying the shoots of the red 

 currant that it takes a position of economic importance to the fruit 

 grower, and to this circumstance I am indebted for having been able 

 to investigate the species, Mr. C. D. Wise, of Toddington, having 

 kindly supplied me with abundance of full-grown larvae last April. 

 Mr. Charles Whitehead also supplied me with some material, and tells 

 me that he also succeeded in observing the moth lay her eggs. I may 

 reasonably hope that the further portion of the life of the moth that 

 I have been able to trace may, in due time, suggest some means of 

 resisting it as a pest, and so repay such kind assistance. 



Certain moths, which 1 reared from the larvae sent me, paired 

 readily in captivity, and, supplying these with a spray of red currant, 

 with berries rather more than half grown, I had the pleasure of seeing 

 the moth lay eggs in such currants on several occasions. The moths 

 were then sleeved out on growing currants, and here also they laid 

 eggs, though I did not see it done. 



The moth is probably the largest of our Adelidce, if robustness
