Insects. 125 



all these insects under glasses for some time, but could not discover 

 the eggs of the fly, although there were several young caterpillars bred 

 under my glasses. If the same circumstances should occur during 

 the next turnip season, I should think many discoveries might be 

 made, both with regard to these flies as well as to the Aphides, by any 

 one who has time to examine them minutely, and I think every ento- 

 mologist will find them well worthy of his attention. 



I forgot to state that there was a similar visitation in the same dis- 

 trict in Northumberland about seventy years ago ; since which time, 

 until last year they had not been observed. — G. Clarke. 



[See Rusticus of Godalming on Aphides. " The young ones are horn exactly like 

 the old ones, hut less ; they stick their heaks through the rind and hegin drawing sap 

 when only a day old." — Ent. Mag. April, 1833. And again : — " Besides the lady- 

 hird and its gruh there are two other terrihle enemies to the poor Aphis : one of which 

 is a green ungainly looking gruh without legs, which lays flat on the surface of the 

 leaf, and stretches out its neck just like a leech, till it touches one of them : directly 

 he feels one he seizes it in his teeth, and holds it up wriggling in the air till he has 

 sucked all the goodness out of it, and left it a mere empty skin," &c. — Id. i. 223. It 

 is pleasant to find ohservers thus corroborating each other's statements. — Ed.'] 



Note on the occurrence of Rare British Insects. Callidium viola- 

 ceum in abvmdance near Elstree, Herts, on a building made of un- 

 barked larch; first week in June. Locusta Christii? {Curtis), Child's

Description of Psy chop sis mimica. This pretty insect was taken at 

 Adelaide, in South Australia, by Mr. Joseph Addison, and is now in 

 the cabinet of the British Museum. The antennae are wanting, and 

 the head and prothorax are 

 so crushed as to preclude 

 their employment in draw- 

 ing up generic characters. 

 In the wings the nervures, 

 and consequently the cells, 

 ai*e more numerous than in 

 any insect of this order that 

 has come under my notice. 

 Three principal nervures, Psychopsis mimica. 



closely approximate and parallel, divide the basal portion of each wing 

 (the lower as well as the upper) into two regions, whereof the superior 

 or costal region is less than the inferior or abdominal region ; at ra-
