 of every entomologist." — Mag. Nat. Hist. 



"Allow me to point out how slightly Mr. Newman's general arrangement 

 really differs from that adopted in my ' Systematic Catalogue.' "—J. F. Stephens 

 in Mag. Nat. Hist. 



" A perusal (of ' Sphinx Vespiformis ') will amply repay the reader for the 

 requisite time and attention." — Entom. Mag.

 nature."— 5crM(«<or in Entom. Mag. 



" The idea which Mr. Newman has stated, of the superiority of one of the divi-

 deserves much consideration." — J. O. We.itwood, in Entom. Mag.

 is in harmony with so many natural affinities."— £. Douhleday in Entom. Mag.
