Bibliographical Notice. 135 



vious part of this list, published in the Number of the Annals 

 for June, 1857. Since then 1 learn from M. dc la Ferte, who 

 possesses the original specimens which belonged to the Count 

 Dcjean, that it is identical with the Chlcenius eximius of that 

 author, to which I have accordingly restored it. 



My specimens, however, seem to differ somewhat from the 

 normal type of Dejcan. In his the thorax is darker in the 

 middle, while in mine a blackish tint invades both the middle 

 and the base. The yellow markings on the elytra also are not 

 confined to the interstitial spaces specified by Dejcan ; but as 

 I find my examples to vary in this respect, some having the 

 markings more expanded than others, it is obvious that such 

 differences arc not specific.

Elements of Entomolor/y. By W. S. Dallas, F.L.S. 



Loudon: Van Voorst. 1857. 12mo. 



"Amongst the numerous works published on Entomology, it 

 appeared to the author that there was none which gave, in a popular 

 and readable form, an outline of the princij)al groups into which 

 Insects are usually divided. It was with the object of filling up this 

 gap in our Entomological literature, that the present little book was 

 written." Such is the opening sentence of the volume now before 

 us ; and we believe that it will be generally admitted that the Jiiatus 

 to which it refers has been satisfactorily filled up. In some respects, 

 however, we would have gladly seen a still more elementary tone 

 throughout this excellent work, for the minds of beginners, for whom 

 it has been peculiarly compiled, can only take in knowledge by 

 honiu;opathic doses, and are apt to "go off at a tangent" where the 

 details, however carefully selected, are too minutely dwelt upon ; 

 and the subject-matter has been already so well and ably handled, 

 in a scientific point of view, by ^Mr. Westwood, in his admirable 

 ' Introduction to the Modern Classification of Insects,' that the want 

 which has been especially felt by our tyros, at the commencement of 

 their entomological career, is, not an elaborate essay, but a treatise 

 of so brief and rudimentary a character as shall at once put them in 

 possession, in j)roper order, of those primary facts and definitions 

 (unaccompanied by more particulars than what are absolutely neces- 

 sary) which form as it were the merest groundwork and alphabet of 

 their science. Mr. Dallas has, however, takeu a somewhat higher 

 standard in the volume which he has just given us ; and we can only 

 say, that, provided his " incipients" have sufficient patience to follow 

 him throughout the -121 interesting pages which he has prepared for 

 their instruction, they will have no cause, imless indeed wc are much 

 mistaken, to quarrel vvith their teacher.
