PHANEROTURIS, gen. nov. 



Phaneroturis, Saussure (MSS.). 



This genus is based on a single imperfect male specimen. It is so characteristically different from every other 

 locust known to me that there can be no doubt as to its distinctness. 



Form robust ; head large ; antennae heavy, long, and with the joints decidedly flattened on the basal half at 

 least, possibly as long as the hind femora when complete (they are imperfect in the only specimen at 

 hand, only about half of the joints remaining). Eyes large and prominent, a little longer than that 

 portion of the cheeks below them, pointed above, regularly rounded behind and almost straight in front. 

 Vertex about half as wide as the shortest diameter of the eyes, the fastigium gently depressed in front, 

 deeply sulcate and provided in its anterior part with a median carina, which broadens backwards so as to 

 form a wedge -like forward projecting arrangement of the occiput; lateral walls high, meeting in front in 

 less than a right angle ; no definite lateral foveolse. Face long, strongly oblique, straight when viewed 

 from the side ; frontal costa sulcate throughout and continuous to the clypeus, its lateral carinae somewhat 

 undulate, approaching both above and below the ocellus, slightly widest below. Pronotum short, cylin- 

 drical ; the front edge straight ; the hind margin above broadly angulate ; sides longer than high ; median 

 carina coarse, percurrent, cut a little back of the middle by the profound last transverse sulcus ; lateral 

 carinae less conspicuous, slightly arcuate, approaching near the middle and also severed by the last sulcus. 

 Tegmina a little shorter than the abdomen, the apex broadly rounded, the scapular area narrow and not 

 regularly reticulate with oblique veins, the discal area irregularly veined even to the apex, which is 

 likewise somewhat coriaceous. Anterior portion of the wing of the <3 as large as the rest, broadly and 

 regularly fenestrate, both edges of this area being much strengthened, reminding one of the elytron of a 

 male (Ecanthus. Abdomen short, much slenderer than the anterior portion of the insect, the apex blunt, 

 plain. Hind femora robust, extending fully one-half their length beyond the tip of the abdomen. Hind 

 tibiae with ten spines in the outer row. 



1. Phaneroturis cupido, sp. n. (Tab. I. fig. 17, e .). 



Phaneroturis cupido, Saussure (MSS.). 



General colour pale testaceous with a greenish tinge, the light colour somewhat relieved by the slight darker 

 line at the upper edge of the sides of the pronotum, the black anterior heavy edges of the wings, and the 

 dark apex of the hind femora and of the base of the tibiae, which latter are entirely infuscated, save a 

 broad subbasal pale annulus. Antennae infuscated apically. 



Length of body, 3, 12*5; of antennae (approximate) 9, of pronotum 2*4, of tegmina 6, of hind femora 

 9 millim.
