handsome one. Tlie dimensions of the specimen from Georgia 

 are as follows : — Length 23 millim. ; width of vertex 3f 

 raillim. ; width of head 9^ millim.; width of abdomen at 

 base of third segment 10§ millim. ; length of wing 18 millim. ; 

 greatest width of wing 6 millim.

Two specimens, both males — one from Nova Scotia {Red- 

 man), the other with no locality. Prof. Brauer (' Mono- 

 graphic/ &c. pp. 249-250) does not mention that the outside 

 of the anterior femora is thickly clothed with whitish hair.

Three female specimens — two from Nova Scotia [Redman) y 

 the third presented by the Entomological Club, without a 

 locality. These specimens have certainly nothing whatever 

 to do with C. americana, F., but I refer them somewhat 

 doubtfully to C. fontinella, Clk., since tliis species is stated 

 by the author to have the last tioo segments of the abdomen 

 white, whereas in the present specimens only the fifth 

 segment is of that colour. In size, however, and other 

 respects they agree very well with Clark's description, and 

 fontinella is the only species given by Prof. Brauer in his 

 table ('Monographic,' &c. pp. 229-230) to which it is 

 possible to assign them. In 'Insect Life,' vol. v. p. ol9 

 (1893), Townsend describes two female specimens which he 

 assigns to C. fontinella and which were bred from larvae 

 obtained near Dona Ana, New Mexico, " taken from Lepus 

 artemisia (?), the common cottontail of the lower Rio Grande 

 region in New Mexico." Townsend states that his specimens 

 are " without doubt Cuterebra fontinella, Clark ; " but the 

 correctness of the identification seems to me to be very ques- 

 tionable. Clark mentions that C. fontinella is half the size 

 of C. cuniculi, Clk., which he states to be as large as Bombus 

 terresiris ; but Townsend gives the length of his specimens 

 as ''205 millim. to 21 millim.," while he adds that a third 

 specimen received from Colorado, which he also regards as 

 belonging to this species, is " 22 millim. in length." Towns- 

 end's specimens therefore must be nearly as large as C. cuniculi 

 itself. Clark calls C. fontinella the " White-tailed Cuterebra,
