Ueber die Singcicadengattung Perissoneura Distant. 



Von Dr. F. Kar seh. 



W. L. Distant, hat in den Proc. Zool. Soc. London 1883, 

 p. 189 eine Gattung -Terissoneura mit folgender Beschreibung 

 in die Wissenschaft eingeführt: 



„?. Head triangulär, the front prominently and suba- 

 cutely produced; the vertex with the lateral margins slightly 

 convex behind the eyes and prominently produced in front 

 of the eyes. Pronotum at posterior angles about twice as 

 broad as anterior margin, the posterior angles ampliated, 

 deflexed to base of tegmina, and broadly rounded at apices. 

 Abdomen above distinctly and longitudinally raised and cari- 

 nate. Face very prominent, strongly compressed and wedge- 

 shaped, concavely narrowing on its apical half. Rostrum 

 reaching the intermediate coxae. Tegmina elongate, the 

 costa very slightly depressed immediately beyond base, 

 and then sligthly raised and convex from about the apex 

 of upper ulnar area ; the inferior ulnar area with the apex 

 slightly but distinctly broader than base; the space between 

 the apices of the postcostal vein and the postcostal ulnar 

 ramus ampliated, and the costal margin very finely hirsute; 

 apical areas eight, the eighth broadest, and shortest: an 

 additional curved and rudimentary vein connecting the base 

 of the second and the apex of the fifth ulnar areas, this 

 vein is distinet and perfect for a short distance from the 

 base of the second and into the third ulnar areas, after 

 which it is subobsolete; basal area almost twice as long 

 as broad. 



„My knowledge of this most interesting genus is confined 

 to a female speeimen collected by Dr. A. B. Meyer in Celebes. 



„Terissoneura maculosa, n. sp. (Plate XXV, fig. 3, 3a, 3h). 



,,<?. Pale ochraeeousor greenish; ocelli castaneous; meso- 

 notum with two central obeonical dark spots, the bases of 

 which rest on anterior margin ; on each side of these is a 

 much longer and more acutely pointed spot, and a small 

 round spot in front of each anterior branch of the cruci- 

 form basal elevation, which is marked by two central darker 

 lines; abdomen above sparingly pilose, the apical segmental 

 margins paler. Body beneath and legs pale ochraeeous or 

 greenish; femora near apices, tibiae near bases and at apices, 

 and apices of tarsi fouscous. Rostrum with the apex pitehy. 

 Tegmina and wings pale hyaline, the first minutely spotted 

 along all the veins and more or less across its apical half.
