This species was found mating in considerable numbers in the edge 

 of an open piece of woods near Victoria, Texas on June 28. 



108. MELANOPLUS FLAVIDUS Scudder. 

 Melanoplusflmudus Scudder, Proe. Bost. Soc. Nat. Hist., XX, 1879, p. 74. 



Nine males, thirteen females, Golden June 19 and August 21; Fort 

 Collins August 11. 



Some of these specimens are quite brightly yellowish and others are 

 quite uniformly brown, except the posterior tibiae. Some specimens 

 have the lateral lobes of the pronotum with a black postocular band 

 and some are unicolorous. All have the hind femora bifasciate with 

 fuscous above. 



109. MELANOPLUS GLADSTONI Scudder. 

 Melanoplus gladdoni Scudder, Proc. Amer. Phil. Soc, XXXVI, 1897, pp. 28, 33. 



Eleven males, ten females, Golden August 21 ; Fort Collins August 9. 



The specimens from Colorado and Nebraska mentioned by Scudder 

 on page 230 of his revision of the Melanopli agree exactly with this 

 lot from Colorado, otherwise these would have been treated of here 

 as conspersus^ for gladdoni and that species must be very similar, in 

 fact, Colorado specimens in the collection of the Colorado Agricul- 

 tural College are labeled as conspersus. The cerci of some of the 

 specimens, both of the present lot from Colorado and those mentioned 

 above from Nebraska, are apically bent inward at almost a right 

 angle. It may be that they are the true co7ispersus, and ghidstoni 

 occurs only further north. Or, still more likely, (jladstoitl and con- 

 spersus are forms of one variable species. To settle this the type of 

 conspersus^ or typical examples, must be seen.
