Mexico." As all the specimens seen from tbese regions which might 

 be referred to this species (and in some instances have been so labeled) 

 prove to belong to M. packardii, I think it probable that some at least of 

 these localities may be wrongly given. The species indeed differs 

 but slightly from M. packardii, and may prove to be merely a varietal 

 form of it dependent upon station, which in this species is in the dank 

 vegetation of river bottoms where M. packardii occurs but rarely. I 

 took a few specimens of the latter, however, in company with the 

 former.

(Plate XX, fig. 10.) 

 Melanoplus corpitlentus BRUNER!, MS. 



A heavy-bodied form, somewhat above the medium size, fusco- tes- 

 taceous, tinged with ferruginous. Head not prominent, olivaceo- testa- 

 ceous, often much blotched with fuscous, above always much infuscated, 

 generally in longitudinal streaks, the lateral edges of the fastigium 

 more or less blackened, aud with a generally distinct postocular stripe; 

 vertex gently tumid, slightly elevated above the pronotum, the inter- 

 space between the eyes nearly half as broad again (male) or twice as 

 broad (female) as the first antennal joint; fastigium steeply declivent, 

 considerably (male) or shallowly (female) sulcate; frontal costa failing 

 by some distance to reach the clypeus, slightly contracted above, at its 

 widest as broad as the interspace between the eyes, sulcate at, and in 

 the male below, the ocellus, punctate throughout; eyes not very large, 

 feebly prominent in the male, anteriorly truncate (female) or subtrun- 

 cate (male), about as long as the intraocular portion of the genae; 

 antennae red, sometimes a little infuscated apically, somewhat more than 

 four-fifths (male) or than two-thirds (female) as long as the hind femora. 

 Pronotum stout, distinctly enlarging posteriorly, especially in the female, 

 more or less and irregularly clouded with fuscous on the disk, often 

 with a ferruginous tinge especially on the metazona, the lateral carinae 

 occasionally marked obscurely with flavous, the lateral lobes generally 

 but obscurely infuscated at the upper half of the prozona, often broken 

 by lighter tints; disk broadly convex, passing into the subvertical 

 lateral lobes by a rounded shoulder occasionally forming distinct carinae; 

 median carina distinct on the metazona, less distinct (female) or subob- 

 solete especially between the sulci (male) on the prozona; front margin 

 subtruncate, hind margin obtusangulate, the angle generally very 

 broadly rounded; prozona slightly longitudinal (male) or quadrate or 

 feebly transverse (female), distinctly (male) or scarcely (female) longer 

 than the rather obscurely punctate metazona; transverse sulci of pro- 

 zoua tolerably distinct, feebly arcuate, opening forward. Prosternal
