650 Prof. Westwood 071 a species of Apliideous 



bright crimson. The antennae, legs, and honey-tubes 

 are brownish, and the space below the eyes is brown." 



Mr. E. E. Green has sent me a small bottle with 

 specimens of this curious aphis in all its stages ; asexual 

 females, winged and wingless nymphs and larvae, the 

 last-named individuals varying from a very minute size 

 to that of the nymphs or pupae. Mr. Green watched 

 some of the asexual females producing their living 

 young, which are emitted tail foremost, and seem to 

 commence feeding as soon as they are deposited. 



A striking character of the species consists in the 

 enlarged size of the cornicles or honey-secreting tubes 

 springing from the sixth abdominal ring near the 

 extremity of the body, common to many of the species 

 of Aphides, especially in those composing the division 

 to which Koch thence gave the generic name of Si2)ho)io- 

 ■pliora. These tubes are stated by Mr. Green to be 

 carried diverging and elevated at an angle of 45° ; they 

 are sometimes as long as the whole remainder of the 

 insect, and are strongly setose, the fine bristles set on 

 nearly at right angles ; many of the larvae carried a drop 

 of milky fluid at the ends of their tubes. When alarmed 

 the insects suddenly dropped from the leaves to the 

 ground. They are very active, and walk rapidly. 



The drawings which I have made to illustrate this 

 species are from different individuals, communicated by 

 Mr. E E. Green. 



The first figure (fig. 1) represents a winged viviparous 

 female. The wings are of the ordinary large size of the 

 Siphonophorce {Aphis rosa, &c.), the first branch of the 

 post-costal vein being short and oblique ; the next 

 branch is very strongly curved beyond its centre, differing 

 in this respect from the wings of every other known 

 species of the family ; the three branchlets of the third 

 branch are of the ordinary character and form. The 

 hind wing is rather narrowly oval, with a minute hooklet 

 beyond the middle of the anterior or costal margin 

 (fig. 4).* The honey-secreting tubes are exceptionally 



■■'• The post-costal vein of the hind wings in Siplionopliora has 

 only two branches. Mr. Buckton (' Brit. Aphides,' i., 28) calls 

 this vein the cubitus, but it clearly represents the branched vein of 

 the fore wing, and not the slender simple veinlet of the fore wings, 

 to which he gives the name of the cubitus.
