 Burm., Spectrum femoratum, Say, and B. spinosa, tridens, 

 striata, gracilis, hastata, linearis, and mriclis, Burm.)

Lonchodes.

 and pterodactijlus, Gray.) 



Prisomera. 



1835. Gray, " Syn. Phasm.," p. 15. (Includes Phasma femorata, 

 Stoll., P. spinicollis, and P. (?) phyllopus, Gray.) (P. spini- 

 collis is certainly the type.) 



AcANTHODERUS. 



1835. Gray, "Syn. Phasm.," p. 14. (Types, Bacteria scabrosa, Perch., 

 and A. dumerili andspinosus, Gray.) 



1859. Westw., " Cat. Phasm.," p. 48. (Bestricted to A. spinosus and 

 allies.) (Serville rejects Gray's name, on account of his own 

 genus Acanthoderes, in the Longicornia, published in " Ann. 

 Soc. Ent. Fr.," iv., p. 25 (1835, 1 trimestre) ; but as Gray's 

 preface is dated Jan. 14, 1835, and Serville's Paper was only 

 read on Nov. 19th, 1834, it is probable that Gray's work was 

 actuaUy published first.) 



Pygirhynchus. 

 1839. Serv., "Ins. Orth.," p. 260. (Types, P. subfoliatus and coronatus, 

 Serv.) Agassiz writes Pygorhynchus.
