MANTIDES. A very distinct new species has been published by West wood. 

 (Arcana Eut. ii, p. 52, pi. Ixii, fig. 2) : Body and wings narrow, the head 

 with a broad horn between the eyes, and a more slender one, with two points, 

 before each of them; the posterior femora lobed, the abdominal filaments long, 

 foliaceons, jointed only at the base. The insect, Stenaphylla cornigera, 

 Westw., is from the interior of Brazil. 



Besides this there are also figured (ib.), Phyllocrania insignis, "West., from 

 Sierra Leone, a new species, nearly related to those of the Cape ; and Mantis 

 metallica, a very pretty new species from Sylhet. 



CJiarpeutier (Orthopt. 7. fasc.) has represented Mantis sublobata, Serv., from 



Brazil, in both sexes (that is, $ M. pilipes, Serv. ; 5 M. sublobata, Serv., 



bracJiyptera, Burm.) ; M. nndata, F. (Theodyt. undata, Serv.), from the Cape; 



M. zebfiilit, new species, do., M. fenestrata, F., do., in both sexes ; ( $ 



feiiestrattt, P., Burin., vitrata, Serv. , <j> M. prasina, Burin., nana, 



Stoll.) 

 Gueriu (Rev. Zool. p. 14) has instituted (from a South of France species, 



P.Allibertii, which does not appear to be other than Mantis decolor, Charp.,) 

 a new genus, Perlamantis, which is founded chiefly upon this, that all the 

 wings are membranous, a condition which obtains in very many males, parti- 

 cularly in the division to which the species referred to belongs. (The 

 females, on the contrary, have short, coriaceous, rudimentary elytra.) Con- 

 sequently the institution of this genus may be considered to have failed. 



In these Archiv. (18 3, i, s. 390) Zimmerman has given more particular 

 information respecting the devouring of a lizard by the Mantis Carolina. 



SPECTRA. A peculiar form of this family has been described by J. Goudot. 

 (Guer. Mag. de Zool. Ins. pi. 125.) It is apterous in either sex, of short 

 form, and differs from the rest in this respect, that the fore legs are not sinuate- 

 emargiuated at the base. The insects are peculiar also in their mode of life, 

 inasmuch as in the daytime they lie concealed under stones and similar objects, 

 and roam about at night. The author still associates this form with Bacteria, 

 though it deserves, in consequence of the absence of the sinus of the anterior 

 femora, to be formed into a separate genus. He has found three species in New 

 Granada: B. Boyotensis, plentiful, and living gregariously near Bogota, under 

 stones, in moist places ; shining black, four tubercles in the situation of the 

 wings, red in the $ , and yellow in the $ ; B. Roulini, resembling the former, 

 but with red femora ; occurring at a higher elevation, and less frequent ; and 

 B. quindensis, wholly of a dull brown, in the cold region of the Cordilleras ; 

 solitary, under the trunks of trees. In the first species there is a gland 

 within the thorax on each side, the excretory orifice of wliich is situated in a 

 tubercle placed on each side of the anterior extremity of the prothorax, and 

 from which the insect is able to project a milky acrid fluid to the distance of 

 a foot. Both the other species also possess the glands, but the tubercles ;nv
