GEOMETEIDAE.

STERRHINAE. 



This subfamily is .represented by four genera comprising seven species, 

 six of which are included in the three largest and most nearly cosmopolitan 

 genera— Anisodes, Scop>ula, and Sterrha, while the remaining species is a very 

 interesting Symmacra. These are the only four Sterrhine genera yet known to 

 extend into the Pacific eastward of the Solomons ; but it is not impossible that 

 representatives of Organopexia, Ptochophyle, Chrysocraspeda, Problepsis, or 

 Bytharia, all of which reach that group or the Bismarck or Louisiade Archi- 

 pelagos, may yet be discovered in Polynesia. 



Symmacra Warren. 



Nov. ZooL, iii, 116, 1896. 



I refer to this genus only four forms, and even so it embraces two distinct 

 sections. 



A. (Sect. typ.). Hind tibia in <$ with strong hair-pencil and two very 

 unequal spurs ; f acres of Discoglypha : S. regidaris "Warren, 1896, Khasi Hills ; 

 S. inobtrusa (Warren), 1897, S. Celebes (pr. subsp. ?). 



B. Hind femur of also hairy, a strong tuft at its base, the tibia usually 

 with only a single spur ; facies of Dithecodes : S. solidaria Guenee, Spec. Gen. 

 Lep., ix, 348, 1858, Ceylon (nec auctt. al.) = S. quadraequata Walker, List Lep. 

 Ins., xxiii, 762, 1861, Borneo = S. validaria Walker, List Lep. Ins., xxxv, 

 1607, 1866, Celebes ; S. solidaria baptata Warren, Nov. Zool., iv, 224, 1897, 

 Samoa. 



"Symmacra" inconspicua Warren (1899), is not strictly congeneric, but 

 belongs rather to Dithecodes. 



7. Symmacra solidaria baptata (Warren). 



Sterrha (?) baptata Warren, Nov. Zool., iv, 224, 1897 (Apia). 



Upolu : Malololelei, 2,000 feet, 1 24.ii.1924 ; 1 21.iv.1925. 



Tutuila : Pago Pago, 3 $$, i.1924 ; 1 & 3 $$, ii.1924 (Stefiany). 



The author of this species, of which the only specimen hitherto known was 

 the type failed to detect its affinities. Except in the glistening white, not 

 green, colouring, this form differs little from the very widely distributed S.
