ANALYSIS OF PERIODICAL WORKS ON NATURAL HISTORY. 



Curtis's British Entomology. 



No. 9 — 10. contains the following subjects : 



PI. 35. Cryptocephalus bipuslidatus. A species well known on the con- 

 tinent, but never before ascertained to be British. — PI. 30'. Lithosia mtcs- 

 cerda. Never before published as a native of Britain. — 37. Raphidia Ophi- 

 op>sis. The female of this curious insect is figured; the male differs in no- 

 thing but the termination of the abdomen ; the ovipositor of the female is 

 very singular in its structure. — PI. 38. Hedychrum ardens. A splendid 

 species of this beautiful genus new to Britain. — PI. 3D. Thymalus limbatus. 

 This valuable insect, so long unnoticed as British, and apparently confined 

 to the New Forest, has this year been taken in Kent. — PI. 40. Sesia Bomby- 

 liformis. A figure of this charming insect is here given, as well as the larva 

 (we believe for the first time), and the pretty plant upon which it feeds. — 

 Pi. 41. Cimbex 10-macu/ata. A magnificent species, a unique specimen of 

 which is preserved in the British Museum : this also has never before been 

 figured. — PI. 42. Pachygaster Leachii. A new species, not known to Meigen; 

 named after our esteemed countryman Dr. Leach.
