2. UNDETERMINED FORMS. 



1. Poepedetes corallinus Saussure, Rev. Mag. Zool., 1861, p. 158. Mexico temperata. It is doubtful 

 if this Mexican species, unknown to me, belongs in the Melanopli ; it seems to be more nearly allied 

 to Dactylotum. 



2. Pezotettix fauriei Bolivar, Anal. Soc. Esp. Hist. Nat., XIX (1890), pp. 322-323. This species from 

 Yesso, Japan, seems to be a Podisma, but it is described from the female alone, so that I can not 

 place it more closely. 



3. Caleoptenus (sic I) Jlavolineatus Thomas, Bull. U. S. Geol. Surv. Terr., I, Istseries, No. 2 (1874), p. 68. 

 I am unable to determine this southern California species, and am tolerably confident I have not seen 

 it; for in this case there is apparently sufficient in the description to fix the species when specimens 

 are obtained. It has been thought by some to be Oedaleonotus enigma collaris, but that is scarcely 

 possible. 



4. Pezotettix mexicana Saussure, Rev. Mag. Zool., 1861, p. 160. Mexico temperata. From the descrip- 

 tion it is impossible to determine which of the many Mexican species this may be, but I suspect it 

 may prove to be Melanoplus atlanis. 



5. Pezotettix mikado Bolivar, Ann. Soc. Esp. Hist. Nat., XIX (1890), p. 323. Yesso, Japan. Like the 

 other species of Bolivar, No. 2, this is described from the female only, and I can not place it. It is pre- 

 sumably a Podisma. 



6. Caloptenus repletus Walker, Cat. Derm. Salt. Brit. Mus., IV (1870). pp. 678-679. I had thought this 

 species to be probably Melanoplus bilituratus, but there was little in Walker's description whereon to 

 base ;m opinion. Mr. Samuel Henshaw, however, kindly compared bilituratut with the specimens 

 placed under repletus in the British Museum and found them distinct. Walker credited it to "U. 

 States " and " Vancouver's Island," one specimen each, but Mr. Henshaw found no specimens from 

 Vancouver, but two males and a female from " North America," one specimen being further labeled 

 "Illinois." The two males were different species, one being Melanoplus femoratus, the other (Illinois) 

 distinct, but allied to it by the cerci, though with short tegmina (probably Melanoplus viola). It was 

 further doubtful whether the female belonged with either of the males. Certainly, then, we shall be 

 obliged to consign Walker's species to merited oblivion. Probably no one of these specimens is one 

 of the original types. 



7. Calliptamug sanguineipes Serville, Rev. Meth. Orth. (1831), pp. 93-94 [Aerydium sanguineipet 

 Olivier, Encycl. Meth., VI (179J), p. 231]. Surinam. It is very doubtful if this belongs in the Melan- 

 opli. If De Geer's Acridium aeneo-oculatum is the same l his figure would lead us to presume it did 

 not. I have not seen the species.
