1GG REPORT ON ZOOLOGY, MDCCCXLIII. 



The Agrionidse-group has been increased with the following new genera : 

 Rhinocypha, with A.fulgidipennis, Guer., and perforata, Perch ;Micromerus, 

 witli Calopt. lineata, Burin. ; Argia, with Ayr. australe, Guer. ; Mecistoyaster, 

 with M. Lucretia, Dr., &c. ; Microstiyma, with two new species ; Hegaloprepus, 

 with L. ccendata, Dr. 



Pictet (Guer. Mag. de Zool. Ins. pi. 117) has founded a new species, 

 Cordulia splendens, from the South of France, the male of which has been de- 

 scribed by Selys Lougchamps (Ib., and Ann. de la Soc. Eut. de Pr. 2 ser. i, 

 p. 108 ; as also in Rev. Zool. p. 131), who has moreover remarked, 

 that it differs widely from the rest of the Cwduliee, and belongs in all 

 respects to the genus Macromia, Ramb., founded on Indian and North 

 American species, and which differs from the former in the completely divided 

 claws, and double number of minute uerviires in the first costal space ; besides 

 which, however, the minute accessory eye is more distinct than in the former. 

 Porm and colour as in Cordulia. 



Selys Longchamps (Ann. S. E. Pr. p. 107, Rev. Zool. p. 158) has also 

 described the male of Lindema tetrapliylla, and distinguished a second 

 European species, Cordulegaster bidentutus, from C. annulatuSfi&ir. (Itimdatus, 

 Charp.) 



White (Dieffeub. New Zealand, p. 281, n. 97) has described a new spe- 

 cies, Petalnra Carovei, from New Zealand, which differs from P. yiyaniea, 

 Leach, in the broader yellow markings on the thorax ; the dilated anal appen- 

 dages are somewhat rounded ; the anterior border and the apex of the wings, 

 the latter, especially in the hinder wings, dusky. 



LEPISMEN^E. Gervais (Hist. Nat. d. Ins. Apteres, iii, p. 449) has divided 

 Lepisma into two subgeuera, Lepismina, and Lepisma ; the former of which 

 includes the species with short cordate bodies and broad prothorax. 



Templetou (Transact. Ent. Soc. Lond. iii, p. 304, pi. 16, figs. 1-7) has 

 instituted a new species, Lepisma niveo-fasciata, from Ceylon, which gnaws 

 the old Dutch books in the libraries there. 



Westwood (Ib. p. 231) has given a more particular description of a minute 

 apterous insect, which lives under herbage on the earth, and which he had 

 exhibited in 1840, to the Eut. Soc. (Proceed. Eut. Soc. p. 14.) It is about 

 2"' long ; slender, flat, soft, with thirteen rings ; with tolerably large head, 

 many-jointed antennae, pretty long legs directed laterally, two claws on the 

 single tarsal joint, and two long hairy bristles on the terminal abdominal 

 segment; of a whitish colour; very active and nimble. The author regards 

 it as a new genus of this family, and assigns it the name of Campodeu. It 

 has also been found by Gervais (1. c.), who is of the same opinion respecting 

 it. It appears to me, however, very uncertain whether it be not some kind 

 of larva.
