Genus ScHiSTOCERCA Stal. 



The insects, which form the genus Schistocerca, are all large in bod\^ 

 and ample in length of wing. Hence many, if not' all of them, are at 

 times apt to wander far from region to region over most of the sub- 

 tropical and tropical lands of the Western Hemisphere. Like many 

 other groups of locusts, the different forms tend to vary more or less 

 markedly in color, as well as to a certain extent in size. A number of 

 them change color a couple of times during their lives. Especially is 

 this last statement true with reference to the forms which hibernate 

 in the imaginal stage. Many of the species have been described time 

 and again by different writers, who have had occasion to study them. 

 This state of affairs has resulted in a rich and complicated synonymy, 

 difficult to decide without a great amount of material from various 

 localities and access to the types for comparison. Then, furthermore, 

 the earlier writers made their descriptions so brief, that they apply 

 quite as well as two or more species or forms, as we understand them 

 today. 



In the present paper, accordingly, no attempt will be made to 

 discuss the synonymy and probable distribution of the several species 

 coming under notice. 



138. Schistocerca flavolinea sp. nov. 



A remarkably large and strikingly colored insect, which runs to the 

 vicinity oi flavofasciafa in Scudder's Table of the Species of Schistocerca 

 as published on pages 442-447 of Vol. XXXIV of the Proceedings of 

 the American Academy of Arts and Sciences. It naturally belongs 

 with my species, Schistocerca formosa and Schistocerca magnifica, when 

 size and beauty is considered. The forrner comes from Colombia, 

 and the latter from the Bahamas. Our new form is an east Bolivian 

 insect. 



Head comparatively narrow, not quite as wide as the anterior 

 margin of the pronotum, its depth one-half greater than the width; 

 viewed laterally the front is broadly rounded, and somewhat retreating 

 below. Occiput short, rather full or rounded; the vertex between 

 the eyes not depressed and about as wide as the lesser diameter of the 

 inconspicuous eyes; the fastigium of the vertex is gently depressed,
