larger insects aside under the MS. name Schistocerca maculipennis, 

 owing to the decided and large maculations which occupy the disk 

 and apical half of the tegmina. These insects are also characterized 

 by the pale oblique border on the lower margins of the pronotum, 

 as well as by the Mark dotted carina' of the hind femora. The 

 measurements are as follows: length of body, 9, 61 mm., of pro- 

 notum, 1.1.5 mm., of tegmina, 60.5 nun., of hind femora, 32 mm. 

 They also approach Scudder's S. aqualis, but seem to be distinct from 

 it ,i- well. 



The present writer also possesses several specimens of a Schistocerca 

 taken on < Grenada Island in the West Indies, which have likewise been 

 referred doubtfully to Thunberg's colombina. These latter insects, 

 however, are much too small for it, being in the females 41 mm. long, 

 with tegmina that are only 39 mm. long. In general structure and 

 color-pattern these small Grenadan specimens are very similar to the 

 very much larger ones coming from the United States of Colombia. 

 The two should be described as distinct species, and will be later. 



113. Schistocerca magnifica sp. nov. 



By far the largest species of the genus. Readily recognized by its 

 uniform grayish brown color and by having the tegmina largely 

 hyaline and without traces of maculation. Hind tibia? and tarsi 

 tinged above with coral-red. Antenna' flavous. Entire body rather 

 closely clothed with short pale hairs, especially is this true on the 

 meso- and meta-sternum. 



Head only medium in size, a little narrower above than the anterior 

 margin of the pronotum, occiput short, embraced by the former 

 almost to the hind margin of the eyes, the face above the base of 

 clypeus about as long as wide, nearly square; eyes not prominent, 

 narrow, about as long as the anterior edge of the cheeks immediately 

 below them; latter below rather finely and closely punctulate, above 

 together with the occiput smooth; face rugoso-punctate; vertex- 

 bet ween the eyes about a third wider than the diameter of the basal 

 antennal joint, the fastigium of moderate size and very deeply sulcate, 

 plainly broader than long, separated from the upper end of the 

 frontal costa by a transverse impressed smooth area of paler hue; 

 frontal costa not prominent, the lateral walls meeting above between 

 the base of the antennae and evenly divergent below, the sulcation 

 rather profound and continuous to the clypeus; lateral or facial
