form of the body, also iu a particular which has been overlooked by the au- 

 thor, which is, that one claw on the tarsus is stunted, so that only a single 

 claw remains on the side of the evident "pulvillus." The other, Proscopia 

 (Ceplialoc(emc) subaptera, with minute, free elytra, and small metallic-black 

 wings concealed under them, said to be from Brazil, I do not hesitate to 

 look upon as an Astroma, Chard. With respect to the elytra, the author 

 has probably been deceived, in having taken for elytra the broad, coria- 

 ceous, anterior edge of the wings, beneath wliich the metallic portion of 

 them is folded up like a fan. Were elytra really present it would be 

 altogether impossible, on account of their smallness, and the length of the 

 niesothorax (since they would naturally be placed at the anterior extremity 

 of the mesothorax), that they could cover the wings, as the author believes. 

 The little wings of Astroma are not placed, as Westwood here asserts, on 

 the first, but as Charpeutier (Orthopt. descr. et dep. i, tab. iv) has clearly 

 figured, on the second segment behind the prothorax. Lastly, Westwood's 

 figure exhibits, although Ms description is silent upon it, the formation of 

 the claws of Astroma, without " pulvillus," as they have been correctly re- 

 presented by Charpentier. The locality assigned is, without doubt, erro- 

 neous. (Ib.) the author gives also the diagnosis of the new Mastax affinis, 

 from Assam. 



Charpeutier (1. c.) has enriched tliis family with three new genera. 

 Hyalopte.ryx (8. fasc. tab. xlvi), related to Truccalis, the antennce equally 

 ensiform, the head, however, is not turreted; the wings, in the male, 

 furnished with a row of very large, quadrangular specular cells. H. ntfipennis, 

 from Brazil. 



Brachyp&plus (9. fasc. tab. li), without epiglottis, with very minute rudi- 

 mentary elytra ; of the contracted build of ^Edipoda hystrix, with a large 

 prothorax extending far back, and remarkably long posterior tarsi. Br. vi- 

 rcftcois, from Mexico. 



Dactylotum (9. fasc. tab. lii), with thick epiglottis, very cylindrical, with 

 deeply incised prothorax ; reticulated, rudimentary elytra, as long as the pro- 

 thorax ; and little trace of wings ; in the male the inferior anal cover large, 

 boat-shaped, and lined internally with a regularly transversely plicated 

 membrane. D. licolor, from Mexico. 



Besides these the author has figured (ib., fasc. 8, 9) : Ehomalea microptera, 

 Serv., from North America; Acridium herlaceum, Serv., from the Cape; 

 A. plorans, Charp., distributed from the South of Europe to the Cape ; (Edi- 

 poda bisignata, Charp., ib. ; (E. lonyipes, new species, from Sicily and 

 Turkey; differiug from (E. insubrica, which in other respects it closely 

 resembles, by the wings being of a light yellow at the root. 



Keferstein has written upon the noxious Locusts (" Ueber die schadlichen 

 Heuschrecken.") (Eut. Zeit. p. 167. 213. 232).
