An attempt to correlate the epochs of locust-swarms with the com- 
mencement of periods of minimum sun-spots, in connection with which, 
the author examines into the period of occurrence of certain usually rare 
Lepidoptera in the United Kingdom. Two lengthy tables are given in 
support of the author’s views. “ Notes on Locusts in Britain,” by the 
same author, are given; l. c. App. viii. pp. 57 & 58. 
Caloptenus differ entialis and G. femur-rubrum attacked by a parasitic 
fungus, which fills them with small spherical bodies, and which Bessey 
terms Entomophthora calopteni ; H. Osborn, Am. Nat. xvii. pp. 1286 
& 1287. Riley, however, is of opinion that the fungus only succeeds 
the attacks of insect-parasites ; tom. cit. p. 1287.
