The genus Sisantum is closely related to Orphulina, and the two form 

 a group intermediate between the Calephorus-Parorphula type and 

 Orphulella. 



ORPHULINA Giglio-Tos.

 No. 184, pp. 8, 9. 



Type. — 0. pidchella Giglio-Tos. 



This genus can be recognized without difficulty by the characters 

 given by Giglio-Tos. The structure of the frontal costa is c[uite dis- 

 tinctive, at least in several species. 



Orphulina pulchella Giglio-Tos.

Two of these specimens have the dorsum green or tinted with green- 

 ish, the other two being dull ochre in the same region. 



Orphulina balloui (Rehn).

 and 3. [Bay Estate, Barbados, West Indies.] 



This species is really a member of the genus Orphulina and rather 

 closely related to 0. pulchella. It can be separated by the blunter 

 fastigium, which has both the dorsal and lateral aspects showing a 

 more rounded angle, the slightly more elongate ovoid eye, the slightly 

 less longitudinal and more quadrate interspace between the meso- 

 sternal lobes, and the different coloration. The National Museum 

 Collection contains a single female, labelled "West Indies," collected 

 by the U. S. Fish Commission. 

 Orphulina veteratoria n. sp.

Allied to both pulchella and balloui, but separated from the former 

 by the more robust form, the less compressed eyes, the slightly less 

 pronounced expansion of the lateral carinse on the metazona and the 

 slightly more acute fastigium. The male has the interspaces between 

 the sternal lobes much as in Orphulella. From 0. balloui it can be 

 separated by the smaller size, more acute fastigium, the more promi- 

 nent eyes and the heavier caudal femora. This species is not closely 

 related to 0. acuta. 



Size small ; form moderately robust. Head slightly shorter than the
