South African Grasshoppers. 383 



The male type and the only paratypic female are from 

 Salisbury, Mashonalaud, xi. 1905 (G. A. K. Marshall). 



This species seems to be closely related to Ph. cruciata, 

 Bol., and may prove even to be conspecific with it, but the 

 question cannot be solved without the examination of 

 Bolivar's type, and I prefer to give here a description of my 

 specimens which will render it possible later to establish 

 the synonymy. If my specimens are actually conspecific 

 with Ph. cruciata, Bol., then the insect from Zomba men- 

 tioned above represents a distinct and undescribed species. 



As I have not seen both of Bolivar's species of the genus 

 Phorenula., I think it inadvisable to attempt to draw up a 

 key to the species, which must be necessarily incomplete 

 and therefore might only mislead. 



Pachycarus, gen. nov. 



Small and middle-sized grasshoppers, with a thick head, 

 somewhat resembling in habitus and type of coloration 

 certain species of the Palsearctic genus Dociostaurus, Fieb. 



Antennae filiform, with the subbasal joints slightly com- 

 pressed, but not at all dilated, in ? distinctly, in ^ very much 

 longer than the head and pronotum together. . Head large 

 and thick, distinctly prominent above the pronotum, in $ 

 strongly, in ? distinctly reclinate. Frontal ridge in the 

 male fiat or feebly impressed, gradually widened towards 

 the clypeus, almost reaching the latter ; in the female it is 

 more convex, with margins obtuse and disappearing shortly 

 below the middle ocellus. Fastigium of the vertex dis- 

 tinctly sloping forwards, pentagonal, more or less distinctly 

 marginate and impressed; temporal foveolse visible from 

 above, longer than wide, shallow, imperfectly marginated. 

 Occiput without median carina. Eyes shortly ovoid; their 

 height exceeds only a little their length and is subequal to 

 the height of the infra-ocular part of cheeks. Pronotum 

 short, rounded, feebly selliform ; median keel very low, in 

 prozona undeveloped or distinctly more feeble than in meta- 

 zona ; the first and second transverse sulci not reaching the 

 median keel, which is cut by the typical sulcus in its 

 middle ; hind margin widely rounded; lateral lobes dis- 

 tinctly higher than long, narrowed downwards, with the 

 lower margin rotundato-angulate on the middle, and both 

 fore and hind angles obtuse, rounded. Prosternum with 

 a low transveise swelling on its fore margin. Meso- 

 sternal lobes perfectly transverse, about twice as broad as 

 long, with hind angles very widely rounded; interspace 

 scarcely more narrow than the lobes, widened posteriorly.
