Cyrtacanthacris punctipennis. 



Mas. Fulva, gracilis, subtus testacea ; fastigium planum, fere rotundum ; 

 frons punctata; prothorax subcarinatus, margine postico subproducto 

 subangulato ; prosterni spina crassa, obliqua, apice rotundata ; abdo- 

 men testaceum, vitta picea abbreviata ; alee anticee e punctis nigri- 

 cantibus subfasciatee, apice cinereee ; alee postica? cinerea. 



Male. Tawny, slender, testaceous beneath. Head short; tip of the 

 vertex depressed, nearly round; front punctured, slightly oblique, with four 

 well-defined diverging keels; inner keels ending in the flat ridge, which 

 extends from the tip of the vertex. Antennae slender, a little longer than 

 the head and the prothorax together. Prothorax with a very slight keel, 

 which is not apparent near the hind border; four transverse impressed 

 lines, the first, as usual, widely interrupted in the middle; fore border 

 hardly curved ; hind border slightly elongated and angular. Prosternal 

 spine thick, oblique, rounded at the tip, approaching the mesosternum. 

 Abdomen testaceous, with a piceous stripe, which extends from the base to 

 beyond half the length. Fore wings cinereous towards the lip, with nume- 

 rous blackish points, which mostly form very irregular bands ; a row of 

 subcostal black more determinate points. Hind wings cinereous ; veins 

 black. Length of the body 15 lines ; expansion of the fore wings 30 

 lines. 



The prosternal spine is shorter, stouter and more obtuse than that of 

 C. rubiginosa, which it closely resembles. The speckled fore wings distin- 

 guish it from C. spissa.
