ANALYSIS OF PERIODICAL WORKS ON NATURAL HISTORY. 



Curtis^ s British Entomology. No. 12. 



PI. 47. Pogonus BurrelUi, a very pretty species belonging to this genus, 

 (which is Raptor of Megerle) discovered in abundance in Norfolk by the 

 Rev. Mr. Burrell, from whom it receives its name. — PI. 48. Pontia Daplidice, 

 the only figure that has ever been given of a British specimen of this ex- 

 tremely rare insect, those appearing in other works having been drawn 

 from foreign specimens. — PI. 49. Trichiosoma laterale, a species never be- 

 fore figured of a genus formed by Dr. Leach, from the Fabrician genus 

 Cimbex. — PI. 50. Limnobia ocellam, a very pretty species, which, al- 

 though described by Linnaeus, has never before been figured. There are 

 several species with the wings ornamented with pretty ocellated spots; 

 from all of which this may be distinguished by the single black annulation 

 round each femur. 



Having here concluded his first volume, the author thus briefly reviews its 

 contents. " It has been found necessary to establish four new genera, j4ca«<Ao- 

 soma, Sarrothripus, Peronea, and H<Bmohora; five more are now for the first 

 time recorded as British, viz. Pogonus, Omaseus, Xyela, Ibalia, and Eumenet, 

 — Figures of fourteen of the species it is believed have never before been 

 published in any w6rk, viz. Pogontis BurrelUi, Omaseus aterrimus, Aphoditis 

 vUlotus, Hydrometra Stagnorum (with wings), Velia Rimilorum, Peronea ru- 

 ficostana, Cimbex decem^maculata. Trichiosoma laterale, Eumenet alricornis, 

 Clenopliora ornata, Limnobia ocellaris, Pachygaster Lcachii, Anthrax ornata,
