20 PROCEEDINGS OF THE ACADEMY OF [Feb., 



A series of five paratypic males have also been examined, taken 

 from the first to nineteenth of September, 1900. In size they show 

 some little variation, and in color there is a tendency in some speci- 

 mens to a more grayish coloration than in others, while in one specimen 

 the color pattern is much more contrasted than in the type. Pale 

 bars on the lateral angles of the pronotum are sometimes present, the 

 ventral half of the eye also being suffused with seal brown in some 

 specimens, while the small tegminal maculations frequently show a 

 tendency to associate in oblique transverse bars well defined or much 

 interrupted and from one to three in number. 



SCHISTOCEECA St&l.

Fig. 4. — Schistocerca gratissima n. sp. Lateral view of type. (X H.) 



Alhed to S. 'pollens (Thunberg) but differing in the shorter, blunter 

 fastigium, the lesser space between the eyes, the broader and more 

 truly elliptical eye, the more arcuate facial outline when viewed 

 laterad and the anomalous pink and green coloration. 



Size large ; form rather slender. Head with the occiput considerably 

 elevated and rounded, descending regularly to the fastigium and 

 rounding into the frontal costa; interspace between the eyes slightly 

 exceeding the greatest width of the fastigium; fastigium about as long 

 as broad, considerably excavated; frontal costa slightly constricted 



• We do not consider the resemblance of StoU's figure of Gryllus (Locusta) 

 lineatus (Natuurl. Afbeeld. Besch. Springh., PI. XV [B, fig. 57) close enough to 

 specimens of this species to consider them the same. While in one or two points 

 resemblance exists, in a number of others the discrepancies are very considerable. 

 StoU's figure appears to us to be a true Locusta (Acridium of authors).
