Dr. Horrath has recently published a " Monograph of the 

 Hungarian Species of Lygaeidre," at Budapest, 4to, 109 pages,

We are indebted to the Ray Society for the publication of the 

 first portion of Mr. Buckton's excellent monograph of the British 

 Aphididse, forming an octavo volume of 198 pages, with 38 coloured 

 and 3 elementary plates. The family is divided into four sub- 

 families, — Aphidinee, Schizoneurinse, Pemphiginae, and Cher- 

 mesinse, — characterised by the variations of the wing- veins. The 

 first of these sub-families is divided into sections, from the 7- or 

 6-jointed antennse ; those with seven joints forming thirteen 

 genera, and those with six joints forming five genera. The 

 present volume is confined to the first six genera of the 

 Aphidinse. An interesting introduction of 100 pages gives a 

 general summary of the anatomy and natural history of the 

 family, in which it is to be noticed that after stating the different 

 opinions on the subject of honey-dew, the author "is very much 

 of the opinion that the honey-dew, as found upon leaves, is of 

 Aphis origin ; " and that " future enquiry will clear up the 

 question whether this liquid is identical with that discharged 

 from the cornicles" (p. 43). It is further to be noticed that, in 

 plate B, the rostrum of these insects is represented as having 

 " three long setse disengaged from the sheath : these are the 

 representatives of the labium and maxillae." This opinion is 

 quite at variance with the generally-adopted view tbat the 

 "rostral sheath" itself is the representative of the labium, and
