262. ME. R. M'liACHLAN'S KEVISIOK OF 



M. RUFESCENS, p. 220, 24=M. rufescens, Erichs. 



M. Cora, p. 221, 28=M. Cora, Newman. The Malabar example is 

 the type specimen ; the other is not different. 



M. AUSTRALASIA, p. 223, 33, for the most part M, australasitB, 

 Guerin ; but one example from Van Diemen's I^and is M. vitfata, 

 Guerin, and another from " New Holland," without any special indi- 

 cation of locality, is perhaps an undescribed species. 



M. DELiCATULA, p. 224, 36=M. delicatula, Westwood. 



M. DISCOLOR, p. 224, 37=M. discolor, Westwood; the type specimen. 



M. BiSERiATA, p. 225, 38=M. biseriata, Westwood ; the type speci- 

 men. This species differs so greatly from the normal form of Man- 

 tispa that I propose for it the generic term Ditaxis, which may be 

 thus briefly diagnosed : — 



Ditaxis *, n. g. 



MantispcB similis ; sed alis latioribus, valde obtusis ; costa a sub- 

 costa apicis tenus distante ; area costali latiore ; venularum 

 gradatarum seriebus duabus. 



M. 4-TUBERCULATA, p. 225, 39=M. 4-tuberculata, Westwood. 



M. LiNEOLATA, p. 226, 43=M. lineolata, Westwood; the type speci- 

 men. 

 M. INDICA, p. 226, 44=M. indica, Westwood ; a type specimen. 



M. FENELLA, p. 227, 46=Trichoscelia fenellu, Westwood; the type 

 specimen. 



M. viRiDis, p. 227, 47=M. viridis. Walker. This is evidently allied 

 to viridula, Erichsoii, but, I think, distinct. 



G-enus Hoplophoea, p. 228. 

 This belongs to the Mantidce (Orthoptera). 



Genus Ntmphes, p. 229. 



N. MYRMELEONiDES, p. 230, 1 =iV. myrmeleonides. Leach. 



N. EXTRANEUS, p. 230, 2=-Myiodactylus {1) extraneus. Walker. My 

 previous assertion (' Journal of Entomology,' vol. ii. p. Ill), that this 



* I have since received a paper by Brauer (" Beitrag zur Kenntniss der Man- 

 tispiden-Gattungen," Verhandl. d. k.-k. zool.-bot. Gesellschaft in Wien, 1867, 

 pp. 281-286), in which he places M. biseriata in the genus Brepanicus of 

 Blanchard. This Chilian genus is quite imknown to me, save by description ; 

 and I feel rather doubtful if our Australian insect will fall into it satisfactorily, 

 and therefore, for the present, retain my proposed generic term Ditaxis.
