CATALOGUE OF ORTHOPTEROUS INSECTS. 



Phasma venosum, Burmeister, Handb. d. Ent. ii. 2. 585. 

 De Uaan, Orth. Orient, p. 123. 

 Hab. In Brasilia. 



The type of this species is contained in the Royal Mu- 

 seum of Berlin, and has supplied the characters and dimen- 

 sions given above. It is closely allied to M. Servillei. 



10. (425.) Metriotes acuticomis. 



Pallide viridis, nigro reticulata ; antennis nigris, albo an- 

 nularis ; capite bicorni, cornubus brevibus acutis et ocellis 

 tribus parum distinctis instructo ; mesothorace brevi, sub- 

 scabro ; tegminibus longitudine metanoti, ante medium 

 elevatis, areaque costali fasciis obscuris interruptis ; area 

 j)OStica alarum nigrescenti ; pedibus subbrevibus ; abdo- 

 minis segmentis sex basalibus marginatis, reliquis tribus 

 brevioribus. 



Long. corp. unc. 3, lin. 5 ; cap. lin. 2\ ; proth. lin. 2\ ; 

 mesoth. lin. 4 ; metath. lin. 8 ; abdom. lin. 20 + lin. 4 = 

 lin. 24 ; tegm. lin. 8; alar, expans. unc. 4J. 



Phasma acuticome, G. R. Gray, Syn. Phasm. p. 26. 



Phasma bicoruuceps, MS. in B.M. 



Hab. In America aequinoctiali. B.M. 



The type of this species is preserved in the British Mu- 

 seum, and has supplied the above characters and dimensions 

 in addition to those originally given by its describer. De 

 Haan considers M. Servillei and brevipennis to be identical; 

 with which opinion, however, I cannot agree. 



11. (426.) Metriotes Servillei, G. R. Gray. 



Obscure viridis ; capitis vertice spinis duabus erectis 

 nigris divergentibus armato ; mesothorace rugoso, luteo 

 granulato, carina mediana longitudinali vix distincta ; teg- 

 minibus longitudine thoracis, subopacis, fusco-viridibus 

 viridi punctulatis, apice venis viridibus, carina mediana di- 

 stincta, apice spina terminata ; alis circiter longitudine abdo- 

 minis, obscure viridibus, area costali opaca, venis viridibus ; 

 pedibus et antennis viridi et nigro annulatis, his corpore 

 longioribus. 



Long. corp. unc. 3. 



Phasma Servillei, G. R. Gray, Syn. Phasm. p. 26. 



Serville, H. N. Orth. p. 267. 

 Phasma annulata, Serville, Ann. Sc. Nat. xxii. 31 (nee an- 

 nulata, Fabr.). 



Guerin, Icon. R. An. Ins. pi. 53. f. 1. 

 Griffith, An. K. Ins. pi. 110. f. 1. 

 Hab. In Brasilia. 



12. (427.) Metriotes brevipennis. 

 Viridi-cinerea ; capite 3-ocellato, utrinque bimaculato, 

 vertice spinis duabus gracilibus armato ; tegminibus alia 



triplo brevioribus, ellipticis, in disco mucronatis ; mesotho- 

 race circiter duplo longiore prothorace ; pedibus brevioribus, 

 femoribus anticis paulo dilatatis ; antennis fceminae corpore 

 multo brevioribus. 



Long. corp. foem. unc. 2| ; cap. lin. 2 ; anten. lin. 17; 

 proth. lin. If ; mesoth. lin. 4 ; metath. lin. 4 ; abdom. lin. 

 12-|-liri. 3=lin. 15 ; tegm. lin. 4£ ; alar, expans. unc. 2J. 

 Phasma brevipenne, Burmeister, Handb. d. Ent. ii. 584. 



Hab. In Brasilia interiori. 



De Haan refers this species and M. Servillei to the Pla- 

 tycrana acuticomis of G. R. Gray. I am not able to de- 

 termine whether Serville's insect be identical therewith, and 

 have consequently given it as distinct, although there seems 

 to be a great resemblance between the two. A careful exa- 

 mination of the type of Burmeister' s species, iu the Berlin 

 Museum, has, however, satisfied me that there is no identity 

 between it and M. acuticomis. 



13. (428.) Metriotes rugicollis. 



Pallide flavescenti-brunnea ; pro- et mesothorace sca- 

 berrimis, tuberculis nigris ; tegminibus basi lineis brevibus 

 duabus nigris ; alis flavo-albis, fasciis interruptis et nervis 

 juxta basin nigris, basi coccineis ; abdomine nigrescente ; 

 pedibus lineis elevatis striatis subhirsutis. 



Long. corp. circ. (apice mutilato) unc. 2f ; cap. lin. 2 ; 

 anten. lin. 25; proth. lin. 2; mesoth. lin. 4£ ; metath. 

 lin. 6} ; abdom. — ? ; segm. 5 basal, lin. 13; tegm. lin. 6; 

 alar, expans. unc. 4£. 



Phasma rugicollis, Curtis, MS. 



G. R. Gray, Syn. Phasm. p. 38 (Platycrana r.). 

 Phasma lichenale, Burmeister, Handb. d.Ent. ii. 584. 

 Hab. In Brasilia; Rio Janeiro. Mus. Curtis. 



I am indebted to Mr. Curtis (in whose collection the 

 typical specimen described by Mr. G. R. Gray is still con- 

 tained) for an opportunity afforded to Mr. Haliday for 

 making a sketch of this species. The type is a male, of 

 which the extremity of the abdomen is mutilated. Having 

 also examined and drawn the typical specimens of Ph. 

 lichenale of Burmeister, in the Berlin Museum, I have 

 scarcely any doubt of their identity with Mr. Curtis's in- 

 sect. The following are Burmeister's characters of his Ph. 

 lichenale : — 



" Viridi-cinereum ; antennis annulatis, alarum area an- 

 tica roseo fasciata, postica venis transversis nebulosis ; ely- 

 tris tuberculo medio rugoso ; dehinc fascia rosea. 



" Mas. Pedibus mesothoraceque elongatis gracilibus. 



" Foemina. Crassior, robustior ; pedibus brevioribus, fe- 

 moribus crassioribus, anticis compressis. 



" Hab. In Brasilia interiori."
