230. Genus ASPASIANA DISTANT 



Aspasiana Distant, Rhynch. Notes 26 (1916). 



Ciiaracters : This genus was erected to accommodate a single species which stood in the 

 British Museum collection under Walker's MS name « carbonaria ». The species had not been described 

 and Distant. therefore, described both genus and species. The type specimen is a large, smooth, 

 shining black insect with a superficial resemblance to the forms of the Neotropical genus Antona. It is 

 characterized particularly by the short, sharp, laterally extended suprahumerals and the flat, laterally 

 globose posterior process. Head slightly defiexed, subquadrate, twice as broad as high; base arcuate 

 and sinuate; eyes ovate; ocelli large, prominent, nearer to each other than to the eyes and situated near 

 the upper margin of the head, far above a line drawn through centers of eyes; inferior margins of genae 

 sinuate; clypeus strong, extending for about half its length below inferior margins of genae. Pronotum 

 depressed, moderately convexly gibbous, bearing a pair of short, sharp suprahumerals and a broad, 

 compressed and laterally globose posterior process; metopidium sloping, broader thanhigh; median 

 carina percurrent; humeral angles heavy and triangular; suprahumeral horns sharp, extending almost 

 directly outward and curving backward; posterior process distinctly raised above the scutellum at base, 

 then broadly compressed with the lateral areas globose, then suddenly narrowed, tricarinate and 

 depressed, impinging on the tegmina, tip acute and extending almost to the tips of the tegmina ; scutellum 

 largely exposed, triangular, longer than broad. Tegmina subhyaline; basal and costal areas narrowly 

 coriaceous and punctate; veins strong; five apical and two discoidal cells; tip pointed; apical limbus 

 narrow. Legs heavy, femora cylindrical; tibiae triquerate, sulcate and spined; hind tarsi longest. 



Type carbonaria Distant. 



Geographical distribution : This genus is known only from the type species from New Guinea.

231. GENUS TSHAKA DistanT 



Tshal<a Distant, Ins. Trans. 214 (1908). 



Characters : The insects of this genus suggest in general facies those of the genus Anchon but 

 the hind wings have four apical cells and the posterior process is quite different in generic structures. 

 Head strongly convex, subquadrate, broader than high; base highly arcuate and feebly sinuate ; eyes 

 large, globular and protruding; ocelli small, inconspicuous, a little farther from each other than from 

 the eyes and situated about on a line drawn through centers of eyes; inferior margins of gense sinuate 

 and extended forward; clypeus broad, extending for more than half its length below inferior margins of 

 gense, tip rounded. Pronotum convexly gibbous, bearing strong suprahumerals and a sinuate posterior
