80 REVIEWS. 



attempts to supply much-felt existing deficiencies ; and while each is par- 

 ticularly accommodated to its own circle of readers, they may both be 

 serviceable to «//, as mutually supplementary. We reserve for a future 

 occasion a more particular critical examination of them, when further ad- 

 vanced towards their completion respectively : our object now has been 

 only, or chiefly, to bring them under the notice of British Entomologists, 

 who are discontented with the home-made provision for the wants of the 

 Beetle-collector, and desirous of some stronger food to promote scientific 

 growth. While they are only in progress, we recommend, for present use, 

 Redtenbacher's book, as already complete in its own sphere of investiga- 

 tion, and as approved by our private experience, in its application as a 

 guide to the correct and easy determination of the great majority of the 

 British beetles also. 



V. Neuroptera. There has been a lull, as if of exhaustion, in this 

 order, since the appearance of Fischer's excellent Monograph of the Euro- 

 pean Orthoptera ; Fieber having only followed in the wake of that, and 

 Von Brauer's investigations being concerned with Physiology more than 

 Taxiology. The Entomologist's Annual, again, furnishes British collectors 

 with a popular description of the native Libellulidae by a master in the 

 science, Dr. Hagen. Mr. Stainton deserves their best thanks for the effec- 

 tive aid he has enlisted on behalf of British Entomology ; and we hope to 

 see many more such contributions introduced to home readers, through his 

 intervention. 



VI. Hemiptera. The system of Heteroptera, in the completed work of 

 Hahn and Henrich-Schseffer, has been receiving large additions, both in 

 genera and species, at the hands of Staal, chiefly from the materials 

 collected by Wahlberg in Caffraria. Kirschbaum has added materially to 

 the European species of Capsus, &c, in his list of the Capsini of Wiesbaden. 

 The illustrated Monograph of Aphides, by Koch, seems to have come to a 

 stand still. We have been looking out in vain, also, for the promised 

 volume on the British Hemiptera, by Mr. Dallas, which was to have pre- 

 ceded the concluding volume of the Diptera, in the series of "Insecta 

 Britannica." Although Mr. Walker's volume is out, and Mr. Dallas makes 

 no sign, we hope the other is not superseded, but only lying by awhile, to 

 ripen more completely. 



In general Entomology, probably the most important production of the 

 past year has been the Seventh edition of Kirby and Spence's Introduction, 

 which we reviewed at the time of its appearance ; while the most novel, 

 undoubtedly, is a weekly newspaper for Entomologists, which, we perceive,
