Siphonopfiora c/trifnlU, Ashmead. 



An aphis has been recorded under this name as occurring on oranges in Africa ; as pointed 

 out later, it is only A jilt is gossi/pii, Glov. Gowdey probably refers to this species when he 

 speaks of Aphis citri, Ashmead (Uganda Insect Pests, Ent. Leaflet No. 2, p. 7, 1909). Hubbard 

 (Insects affecting the Orange, U. S. A. Dept. Agric. Div. Ent. p. 157, pi. xiii, fig. 3) refers to the 

 Orange Aphis as S. citrifolii, Ashmead, but his figures are of a Toxoptera. Saunders (Insects 

 Injurious to Fruits, p. 388, fig. 398, 1892) also under this name figures a Toxoptera. 



Macrosiphoniellat bedfordi, sp. nov. 



Apterous viviparous female. — Blackish ; antennae longer than the body, the 

 basal part of the third segment pale ; legs pale, the apical two-thirds of the 

 femora, base and apex of the tibiae and the tarsi, black. Cornicles and Cauda 

 black. Antennae with the first segment considerably larger than the second, 

 both black ; the third the longest, not quite as long as the fourth and fifth 

 together, with 18 to 20 sensoria along the outer border for nearly the whole 

 length ; fourth segment shorter than the third, about as long as the fifth ; the 

 sixth about as long as four and five together ; a subapical sensorium on the 

 fifth and a group at the junction of the basal area and rlagellum in the sixth; 

 the first and second segments, with a few long hairs, the third with about ten 

 outstanding ones on the outside, three on the fourth and two on the fifth. The 

 head is concave in front, with several long hairs ; frontal processes not very 

 marked ; eyes prominent ; the proboscis does not quite reach the third pair of 

 legs. Abdomen with a few long outstanding pale hairs. Cornicles black, of 



* Buckton's record may be an error, as a very similar aphis attacking roses has recently been 

 sent to me from Lahore by Bashambar Das, which he is describing as M. rosaeiformis. 

 ■f This is a genus recently created by Del Guercio for a closely related chrysanthemum species.
