have hi'en e()lle(_-ted. Scries nt' tliese were sent to Messrs. J. A. (i. Kelm 

 and Morgan Ilebard, who int'onned nie that tliey consider Xanthippus 

 obscurus (Scudder) to be an absolute synonym of Xanthippus neglectus 

 (Tii(inuis) ; and it must therefore l)e struek off tiie list. 



It is furthei- considered that the species listed in the present paper 

 as Xanthippus leprosus (Saussnre) and the species listed in the former 

 pajiei' as Xanthippus latefasciatus (Scudder) ])robably represent one spe- 

 cies in liritisli Coluiiibia. 



Tiie.v find that the materi.d submitted to them for determination dur- 

 iiii:' the past few years arrets with matei'ial determined by Scudder as 

 leprosus, but may not l)i' iileiitical with the leprosus of Saussure. which 

 was described from Mexico. The melius is a difticidt one. and more woi-k 

 is neede(l to detiuitely dctermiiu' what species we have represented in 

 Canada. The two nauu's, leprosus and latefasciatus, are temporarily re- 

 tained until further work can be done on the ji-enus. 



Mr. Kehn informs me that in the genus Trimerotropis the species 

 listed as Trimerotropis ferruginea (McNeill) will pr<ibably be f(uuul to 

 be a synonym of Trimetropis caeruleipes (Scuddei-). 



Tlie record of Trimerotropis citrina (Scudder) was matle from a 

 single specimen collected l)y Mi\ E. P. Venables at Vernon in I'JO.") and 

 recorded by Dr. James Fletcher as this s])ecies. The specimen has been 

 examined and found to be a male Spharagemon aequale (Sayi in which 

 the notching of the median cai'iua of the pronotum closely resembles a 

 member of the genus Trimerotropis, as there is a tlistinct second notcli. a 

 featui-e which occasionally occurs in specimens cd' Spharagemon aequale 

 (Say). 



It is probable that Trimerotropis citrina (Sciulder) will not be found 

 in Canada. 



The type s)iecimeii of Trimerotropis longicornis ( E. M. Walker) was 

 recently comjiared by Prof. Walker and the author to material collected 

 in British Columbia which had been determined by Mr. Rehn as Trimero- 

 tropis monticola (Saussui-e), and found to be very close to if not identical 

 with this matei'ial. In liritish Columbia Trimerotropis monticola (Saus- 

 sui-e) has yellow hind tiijiae ami does not bear much superficial resemb- 

 lance to the monticola found on the ju-aii'les in Canada. It is tliought, 

 however, that Trimerotropis longicornis (E. M. Walker) may eventually 

 be found to be Trimerotropis monticola (Saussure). 



Mr. Morgan Ilebard infoi'ins me that he finds Melanoplus flabellifer 

 (Scudder) to be an absolute synonym of Melanoplus occidentalis (Tho- 

 mas). 



In. the in-evious list I jjlaced Thomas as the author of Melanoplus 

 mexicanus atlanis; this is incorrect ami should i-ead (Hiley) Aiui. liep.
