SCUDDER SUPPLEMENT TO A REVISION OF THE MELANOPLI. I 77 



noticeable attingent projections of the last dorsal segment; cerci 

 tumid obpyriform, consisting of an ovate tapering basal bulb and an 

 apical, scarcely tapering, blunt finger of equal length, the latter gently 

 incurved and just failing to reach the tip of the supraanal plate; sub- 

 genital plate narrow and rather small, the lateral margin of each side 

 elevated basally to twice the normal height to form a rounded lobe, 

 and the apical margin elevated to form a lesser blunt triangular lobe 

 as seen from behind. 



Length of body, cf, 15.5 mm., 9, 21 mm.; antennae, cJ*, 5-5 mm., 

 ?, 7.5 mm.; tegmina, 0^,4.25 mm., ?, 5 mm.; hind femora, c?, 

 10.5 mm., 9, 14 mm.

This species is nearest the larger M. borckii and M. pacificus, differ- 

 ing mainly in the longer apical finger of the male cerci. 



Melanoplus islandicus. 



Melanoplus islandicus Blatchl.! Psyche, VIII., 196-197 (1898). 



Melanoplus abortiviis Walk.! Can. Ent., XXX., go-92 (1898). 



Described by Blatchley from Les Cheneaux Islands, Michigan, and 

 by Walker from DeGrassi Point, Lake Simcoe, Ontario, and Aurora in 

 the same province. Blatchley referred it to the Puer Series on my 

 statement, but I was in error in supposing the cerci to be styliform 

 and not to taper irregularly as they do. I introduce the species here 

 to indicate its place in the series. 



Melanoplus truncatus sp. nov. 



Plate VII., Figure 8. 



Of medium size or slightly below it, dark fuscous above, flavo-testa- 

 ceous below, with a very broad piceous postocular band, which crosses 

 the whole pronotum, but is sometimes diluted on the metazona, and 

 . with conspicuous pale flavous stripes on the metapleura and along the 

 lower margin of the outer face of the hind femora. Head hardly 

 prominent, plumbeo-olivaceous, varying to testaceous, more or less 

 infuscated, at least above, and with the postocular stripe edged nar- 

 rowly with dull flavous; vertex gently convex, only slightly elevated 

 above the pronotum, the interspace between the eyes considerably 

 broader. than the first antennal joint ; fastigium steeply declivent, dis-
