British Entomologi/ ; or, Illustrations of the Genera of 

 Insects found in Great Britain and Ireland, 8fc. By 

 John Curtis, F.L.S, Nos. vii — xii. 



In enumerating the genera of British Insects illustrated in the 

 numbers of this work quoted above, we shall omit all mention of 

 the plants figured therein, as foreign at least to our purpose, and 

 shall touch briefly on the Zoological portion of it alone. The 

 Seventh number, with which the present series commences, con- 

 tains, 1. Aphodius villosus, an extremely rare species, known as 

 British only by a single specimen in the cabinet of Mr. Vigors. 



2, Acantliosoma hcemorrhoidalis (Cimex haimorrhoidalis, Lin.), 

 ■which has been adopted by Mr. Curtis as the type of a new Genus, 

 diflfering from the other Pentatoraidae by its two-jointed tarsi and 

 the great length of the first joint of its antennae, and whose name 

 alludes to the singular conformation of the spined keel beneath 

 the abdomen, which seems to protect the rostrum. 3. Sarrothri- 



pus ratnosana, also a new genus, formed by the section Palpanae 

 of Tortrix in Mr. Haworth's Lepidoptera Britannica, and of which 

 the present species is new to English Entomology. 4. Xyela 

 pusilla, a singular and little known genus of Xiphydriadae, which 

 evidently connects the families of Tenthredinidae and Uroceridae, 

 to which latter it was indeed referred by Dal man, who first de- 

 scribed it in the Stockholm Transactions. It is well characterized 

 by the extreme length of the third joint of the antennae, which is 

 equal to that of the nine following ones. 



The eighth number contains, 1. Buprestis nitidula, a beautiful 

 little species of this splendid genus, recently captured for the first 

 time in this country by Mr. Curtis ; 2. Hydrometra stagnorum ; 



3. Bupalus favillacearius, ^ and ? ; and, 4. Milesia speciosa. 

 The ninth number comprises, 1. Cryptocephalus bipustulatus, 



a single specimen of which exists in the cabinet of Mr. Dale; 

 2. Lithosia muscerda, captured by Mr. Sparshall ; 3. Raphidia 

 Ophiopsis ; and 4. Hedycrum ardens, a rare and very splendid 

 insect.
