collected between 33° and 41° South Latitude, in the provinces of Santiago, 
Malleco, Arauco, and Valdivia. 
Helocharina is similar to Syncharina in many ways. It may be separated from 
the latter by its lack of punctation on the pronotum, and scutellum, and by its 
stalked paraphyses in the male, both differing from Syncharina. I confused 
these genera early in the progress of this work and returned a number of 
specimens with erroneous generic names on the labels. 
My identification of H. gayi (Spinola) is based on photographs of a female 
specimen from the Spinola collection in Tassarolo Castle, Italy. I am greatly 
indebted to Dr. Carlo Vidano for making the photographs available. I have 
associated these photographs, with the aid of the original description, with a 
series of specimens at hand. The specific synonymy has resulted from a study 
of the lectotype of Tettigonia albinervosa Signoret, which Signoret himself iden- 
tified with albonervosa Spinola.

FicurRE 499 
Length of male 6.0-6.1 mm, of female 6.5-6.7 mm. Head with median 
length of crown varying from slightly more than one-half to two-thirds in- 
terocular width, and from one-third to slightly more than four-tenths trans- 
ocular width; face with clypeus not flattened medially, lower portion of 
clypellus continuing profile of clypeus. Forewing with an anteapical plexus of 
veins. Male plates not extending posteriorly as far as pygofer apex, without 
conspicuous anteapical setae but with a pair of elongate slender setae at apex; 
paraphyses with apical half not lying in median plane, rami limited to apical 
portion of apical half. Female abdominal sternum VII strongly produced 
posteriorly, gradually narrowed to bluntly angulate apex; dorsal teeth of 
second valvulae of ovipositor more widely spaced than in H. gay: (Spinola). 
Color of male crown mostly black on disk with arcuate ferruginous area on 
anterolateral margins on each side near apex and before each eye, disk with a 
median apical lobate (trilobed, or sagittate with base bilobed) marking, a pair 
of median basal linear or L-shaped markings, an oval marking including each 
ocellus, variable additional markings, dull, yellow; crown of female ferru- 
ginous with pale markings variable, in some specimens as in male, in others
