CATALOGUE OF ORTHOPTEROUS INSECTS. 



fere duplo breviores ; abdomen magis latum quam in Ph. 

 gigante. 



" Duplo minor P. gigante." 



Phasma grandis, Thunberg, Hemipt. Max. Gen. Illustr. in 

 Mem. Acad. St. Pi'tersb. v. 295. 



Hab. ? 



The above is the whole of Thunberg' s description of this 

 insect, of which also he has omitted to publish the habitat. 



Obs. Phasma acicularis, Stoll (Phasma, pi. 25. f. 97), 

 referred to Mantis by Mr. G. R. Gray (Syn. Phasm. p. 44), 

 appears to me to be a specimen of a Ranatra deprived of 

 its tails. 



P.S. — Mr. Bates has just forwarded to England a remarkable species, of which the following are the characters : — 

 P. Ki4.— Sp. 4*. (471.) Dinelytron Batesianum, TFeshv. 



Elongatum, cylindricum, htve ; capitis viridis vcrtice eonieo, 

 elcvato, bispinoso ; prothorace nigricante ; mesothorace brevis- 

 simo, albo ; metathorace abdoraineque piceis ; tegrainibus nigris 

 macula maxima costali alba; alis nigris macula magua basali 

 triangulari alba ; pedibus obscure viridibus (fcem.). 



Long. corp. udc 2J ; cap. lin. 2 ; anten. lin. 12-| ? ; proth. 



lin. 1£; mesoth. lin. 2J ; metath.lin. 5 ; abdom. lin. lSJ+lin. 3 

 =lin.l6^; tegm.lin. 10; alar, expans. unc. 3. 



Hab. In Brasilia, ad fluv. Amaz. super. (D. Bates). 



Closely allied to D. Zymbraus. Head green, larze, hind part 

 conically elevated, and armed with two acute divergent black 

 spines, separated by an impressed line. Ocelli wanting. Au- 

 tennffi moderately long, the 4th to the 9th joints short, the re- 

 mainder gradually elongated and black ; first and second green. 

 Protborax quadrate, glabrous, dirty blackish, with a transverse 

 impression in front. Mesothorax rather longer than the pro- 



thorax ; cream-white, except at its dirty posterior margin, with 

 a very thin central green line. Metathorax and abdomen 

 pitchy and glossy ; three terminal segments of the latter short 

 and compressed ; two anal styles short, slender, and divergent. 

 Operculum thin and flat, not extending beyond the eighth dorsal 

 segment. Tegmina oval, half the length of the wings, slightly 

 elevated towards the base ; black, marked with a large oblong 

 cream-white patch along the costal area, extending into an oval 

 spot on the disc between the middle and base. Wings large and 

 black, with a large triangular cream-white spot extending from 

 near the base to beyond the middle of the wing, and reaching 

 from the costal margin halfway across the wing ; chief vein of the 

 costal area trifid. Legs short, spineless, dirty greenish black ; fore 

 femora slightly curved ; under side of the body pitchy brown, with 

 the metasternum pale dirty white, except at its hinder margin. 



I have named this species after its discoverer, to whose inde- 

 fatigable exertions in Brazil, English entomologists are indebted 

 for many of the finest acquisitions to their cabinets.
