venation ochraceous and irregularly spotted with fuscous. Wings 

 pale hyaline, the venation fuscous, their bases somewhat shining 

 pale green. The cephalic process is almost equal in length to the 

 distance from its base to the apex of the mesonotum, and its apex 

 is distinctly incrassated, but laterally compressed.

Allied to C. fcrocida, Stal, but separated, apart from 

 other structural characters, by the basal green coloration 

 of the wings. 



Scamandra diana, n. sp. (PI. XIII., fig, 4), 



Body above brownish ochraceous, the mesonotum darker in 

 hue ; pronotum with two faint dark discal spots on each side ; 

 anterior segmental margins of the abdomen pale castaneous. Body 

 beneath ochraceous or pale castaneous ; a broad central fascia to 

 face, margins of sternum and the femora blackish, the tibiae oliva- 

 ceous, bases of the posterior femora castaneous. Tegmiua with 

 about basal two-thirds olivaceous green, containing a reddish 

 ochraceous spot at costal base, and a large basal claval streak, 

 followed by two small spots, a discal spot, and a transverse fascia, 

 all pale ochraceous ; the green area terminates by a much waved and 

 sinuate narrow black fascia ; apical third pale brownish ochraceous, 

 the venation very finely reticulate and paler in hue. On the under 

 side of the tegmina the discal spot and transverse fascia are bright 

 creamy white. Wings with about half or basal area olivaceous 

 green, shaded with blackish, the extreme base narrowly testaceous, 

 and the inner, outer, and apical (the last very broad) margins pale 

 brownish ochraceous, reticulated as on apex of tegmina. The 

 tubercle at the base of the posterior tibia; is in the form of a more 

 or less acute spine ; the mesonotum is distinctly rugulose. 



This species is allied in general coloration to 8. dajihne, Btal, 

 but the apex of the tegmina is considerably narrower, the sculpture 

 of the frontal part of the head quite different, and the pronotum 

 has a distinct central carina on its postei'ior half. In general 

 structure and size it is more closely allied to S. arcuigera, Stal.
