Length of 9 2 mm. 



Type, a $ taken by the Rev. "Robert Godfrey, M.A., in No- 

 vember or December, 1908, from IIus rat f us, at Pirie, King William's 

 Town, South Africa. The species is named after members of the Ross 

 family in Pirie, who have frequently assisted Mr. God Prey in his 

 collecting. 



I am greatly indebted to the Hon. N. C. Rothschild, MA., who 

 has examined the specimen, confirming tiiy suspicion that it repre- 

 sented a new species. He has also with characteristic kindness 

 supplied some unpublished details of O. ocfnvii ftir the purpose of 

 comparison. Full descriptions of C. numas and C. octavii, will be 

 found in " Novitates Zoologicae," Vol. xi, September, 1904, pp. 

 637-639 ; pi. xii, fig. 58 ; pi. xiii, figs 59, 61, 63, 65. 



My best thanks are also due to Mr. Robert Adam, who took 

 photographs of Dr. Jordan's figures and my own for the accompany- 

 ing plate. 



[Since writing the above I have received from Mr. Godfrey a J Ceratophyllus, 

 from the same locality and host, belonging apparently to the species just described. 

 Like the ? it showed characters intermediate between those of C. octavii and C. 

 numse. Tlie 9th sternite bore distally three beautiful leaf-like appendages as in 

 numse, but of a different shape. This specimen, which was slightly over TG mm. in 

 length, most unfortunately disappeared in mounting. — -J. W.].

SETULIA GRISEA, Mo., and CERCERIS ARENAEIA, Linn., 

 IN THE NEW FOREST. 



BY A. H. HAMM. 



On August 7th last I joined my friend, Mr. G. Arnold, for a few 

 days entomologizing together, at Hrockenhurst. I am indebted to 

 him for kindly pointing out the nidificating sites of many interesting 

 species of Fossorial Wasps, and in other ways conducing to my comfort 

 and enjoyment, both on this and previous visits to the Forest. 



Our first excursion (August 8th) was to the ground near the
