ochraceous band along clavus and costal area ; clypeus deep fuscous at anterior half, ochraceous 

 at posterior half; clypellus ochraceous. 



Head narrower than pronotum; crown long and narrow, produced distally beyond anterior 

 margin of eyes, distal length about one-third entire median length, striate radially, slightly 

 depressed medially, lateral margins slightly convex, disk elevated above level of eyes; ocelli 

 moderate size, situated anteriorly; eyes moderate size, occupying nearly two-thirds entire 

 dorsal area of head ; pronotum large, median length slightly greater than median length of crown, 

 surface finely knobbed; scutellum moderate size, median length about equal to median length 

 of pronotum; elytra elongate, veins distinct, appendix well developed, venation as in description 

 of genus ; clypeus elongate, very broad anteriorly, narrowed posteriorly, lateral margins excised 

 near antennal sockets, without median longitudinal carina, surface finely granulose, narrowly 

 rugulose along anterior margin; clypellus with lateral margins constricted medially. 



Male pygofer in lateral aspect with long, curved slender process arising from caudoventral 

 margin, process with lateral margins nearly equidistant throughout, slightly enlarged apically, 

 apex aperturized or appearing segmented; aedeagus in lateral aspect with dorsal appendage 

 broad at basal three-fourths, attenuated at apical fourth, dorsal appendage without spines 

 or flanges, dorsal margins expanded in dorsal view; ventral appendage long, tube-like, extending 

 beyond apex of dorsal appendage; gonopore apical; connective Y-shaped; style clawed apically; 

 plate with distal segment elongate, dorsal margin expanded medially. 



Female seventh sternum with posterior margin produced medially. 



Distribution. Samoa Islands. 



Specimens examined. 



Jassoidula limbata Osborn, holotype $, Samoa: Malololelei, Upolu, 2000 ft 

 (P. A. Buxton & G. H. Hopkins) (BMNH, London); allotype $, Samoa: Savaii, 

 Salailua, v. 1923-1924 (Bryan) (BPBM, Honolulu). 



Samoa: Afiamalu, Upolu, 1 A , 2 $, beating shrubbery, 13-27. vi-4.viii. 1940 (E. C. Zimmerman). 



Biology. Unknown. 



Remarks. From ochracea, to which it is similar in male genital characteristics, 

 limbata can be distinguished by the enlarged apex of the pygofer process and smaller 

 size.

 area of head; pronotum short, median length less than median length of crown, surface finely 

 knobbed; scutellum large, median length greater than median length of pronotum; elytra 

 elongate, veins somewhat obscured, appendix well developed, venation as in description
