The synonymy of the insect, like that of other cosmopolitan spe- 

 cies, is extensive, viz. : — 



Ar^oceuus, Schonh., = Phlosobtus, Steph. 



fasciculatus, Ue Geer. 



coffece, L. 



crassicornis, F. 



cacao, F. 



peregrinus, Hbst. 



japonicus, Thnnb. 



griseus, Steph. 



capillar icornis, Ray. 



wicestus, Lee. 



var. sambucinus, Boisd. 

 When alive the insect i3 very active, possessing much the same 

 jumping powers as Choragus sheppardi. 



In conclusion, I must express my indebtedness to Mr. Newbery 

 for his assistance in the preparation of these notes.

A female of this species taken at light in September, 1907, in 

 the Thames Valley laid her eggs in the corner of the box in which she 

 was kept, ignoring some poplar twigs which were supplied. 



The eggs hatched out at intervals from March 8th to April 6th,
