have no doubt of what he refers to. I prefer, therefore, to 

 accept Monell's position of it until the genus Aphis can be 

 cleared up. * * * Aphis loniccrcc appears to be a rare form; 

 I have only twice encountered it. * * * Some fresh balsam 

 mounts made in 1898 and now pretty well shrunken show the 

 Cauda conical and rather stout ; the anal plate a very low cone. 

 The cornicles are very low, in fact almost on a level with the 

 body on the outer side but distinctly raised above on the inner 

 side. Joint 3 of the antennae have some 40 — 45 circular, 

 scattered sensoria ; and the fourth often with one or two". 

 Mr. Monell's conclusions communicated to me are practically 

 the same; and he says further: "looks to the naked eye like 

 Siphocorync xylostii, perhaps more powdered, and was very 

 common the year I took it. I remember that I was sure of 

 lonicercc not being a Chaifophoriis when I saw it. In these 

 poor specimens [referring to 6ox and 148X] it is hard to form 

 an opinion". The cauda, which was visible only in Monell's 

 148X specimen, is shown in Figure 14, Plate VII. The an- 

 tennae on both the slides loaned me by Monell were too trans- 

 parent to count sensoria, but the antennae of the winged 

 female on the Thomas slide showed 56 and 60 respecti^^ely on 

 segment III ; several on segment IV (but only the tip of the 

 segment was visible) ; a large sensorium at the distal end of 

 V ; and a large one, with several small sensoria surrounding it, 

 at end of base of VI. The third discoidal branches at three 

 eighths the distance from the tip to point where second 

 branches. The head, antenna, cauda, and anal plate are shown 

 in Figures 12-15, Plate VII. 

 Measurements taken (in mm.) are as follows.
