Curtis's British Entomology. 571 



The insects figured in the tenth number are, 1. Thymalus 

 Umbatus; 2. Sesia bombyliformis ; 3. Cimbex deceni'maculata, 

 unique in the cabinet of the British Museum ; and, 4. Pachygas- 

 ter Leachii, a new species of a genus which presents an example 

 of the confusion existing in the nomenclature of Entomology. 

 The generic name Pachygaster was applied by Meigen to an 

 insect congenerous with the present in 1804, while that of Vappo, 

 which has been more generally adopted in England, was not 

 given by Fabricius until the succeeding year. The original name 

 must therefore be retained for the present genus, and a new one 

 be applied to that portion of the Curculionidas to which Germar 

 has affixed that of Pachygaster. P. Leachii differs from the 

 more common P. ater by its wings, which are entirely transparent. 



The eleventh number contains, 1. Scolytm destructor^ a com- 

 mon, and, as its name imports, destructive insect, which is un- 

 fortunately becoming much too frequent in the vicinity of London, 

 committing devastations among the trees, especially in St. James's 

 and Hyde Parks, to so great an extent as to have recently called 

 forth from the pen of Mr. W. S, MacLeay an excellent paper on 

 its natural history, and on the means of checking the mischief it is 

 producing. 2. Clerus alvearius, extremely rare as British; 

 3. Cucullia Asteris^ with its larva; 4. Asilus Germanicus, two 

 specimens of which are contained in the British Museum. 



The twelfth number, which completes the first year of publica- 

 tion, includes, 1. Pogonus Burrellit, an entirely new species of 

 a maritime genus of Carabidae which has been more frequently 

 termed Raptor in the English cabinets ; 2. Pontia Daplklice, 

 figured from the only British specimen now known, captured by 

 and in the possession of Mr. Stephens, but which appears to have 

 been of more frequent occurrence in the times of Ray and Petlver ; 

 3. Trichiosoma laterale ; and, 4. Limnobia ocellaris, a rare and 

 beautifully marked species. 



We cannot conclude this notice without expressing our pleasure 

 at the prospect which the conclusion of the first volume of this very 

 important and valuable publication affords of its continuance. The 

 list of subscribers appended to it, and the knowledge we possess 

 of a considerable sale in othqr quarters, induce us to anticipate a
