Tine forte carene en forme de coin plus ou moins aigu ct dilate " 

 (Hemipteres, p. 562), whereas in Monecphora it is not compressed, and 

 has only a feeble carina, and in Triecpliora it is furnished with three 

 raised lines or carinse. At best the character given for Sphenorhina 

 is a weak one, generically considered, and besides this it is not always 

 strongly marked, and somewhat intermediate examples occur ; the 

 facies of the species differs considerably, some being elongate and 

 parallel, and others short and ovate ; the shape, however, is by no 

 means associated with the carination and compression of the front, as 

 the most similar species in appearance differ in this point ; unless, 

 therefore, we allow undue weight to geographical distribution, we can 

 hardly, in the present state of our knowledge, do anything else but 

 follow Stal, and include the bulk of the Cercopidce under Tomaspis. 



The three following species of Tomaspis are from a portion of the 

 Vienna Museum collection, which has been kindly lent me by Dr. 

 Ganglbauer and Herr Handlirsch. 



Tomaspis (Monecphora) picata, n. sp. 



Elongata, angusta, parallela, coriacea, fronie testaced, vertice nigro, 

 antice uWinque testaceo, pronoto scutelloque nigris, illo basi sinuatd, macula 

 aiitice utrinque, et margine anteriori anguste testaceis, hoc excavato postice 

 acute producto ; tegminibus nigris parte basali dimidid maculdque ante apicem 

 albidis, apicibus regulariter rotund atis ; pedibus testaceis, tibiis tarsisque 

 posticis nigris, pectore infuscato, abdomine ad partem testaceo, apice nigricanti 

 vel toto nigra. 



Sab. : New Grranada, Nolclcen (Vienna Museum Collection). 



var. lugubris — differt margine anteriori projioti haud testaceo, tegmini- 

 busque, maculis apicalibus exceptis, totis nigris. 



Elongate, narrow and parallel, black, with the front, and a spot on each side of 

 the anterior part of the pronotura, testaceous, and the elytra with the basal half, 

 except just at shoulders, and a spot just before apex, whitish ; the legs are testaceous, 

 except the posterior tibise and tarsi, which are black, and the apex at least of all the 

 tarsi is pitchy ; the pronotum has a broad, longitudinal, central furrow, and the 

 scutellum is excavate ; the sculpture is very fine throughout, and gives the insect a 

 dull appearance. Long., 13 mm., lat., 5 mm. 



The variety differs in not having the anterior margin of the pro- 

 notum testaceous, and in the fact that the tegmina are entirely black 

 with the exception of the distinct whitish spot just before apex ; it is 

 also rather smaller. Loug-, 12 mm., lat., 4 mm. 



Tomaspis (Monecphora) Nolckeni, n. sp. 

 Elongata, parallela, nigra, tegminibus testaceis, suh-pellucidis, apicibus
