Similar to typical mollipes in form and structure, a black spot 
on the disc of vertex, a pair at the base, another pair just inside the 
basal angles of the scutellum, and sometimes a third pair on the 
pronotum. 
Specimens of this variety are at hand from Florida, 
Mississippi and Mexico. Signoret considered this a dis- 
tinct species and described it as with a longer head than 
mollipes. There is nothing in Walker’s description to 
indicate this, and the spots on vertex and scutellum are 
about equally common in Yar. minor. Many specimens of 
typical mollipes possess the spots on vertex at the base in 
the form of oblique lines, and some of them have trace of 
fuscous on the disc in place of the spot there. 
Yar minor, Walk. Plate YII, Fig. 3. 
Tettigonia minor, Walk. Horaop. Ill p. 772, 1851. 
Form and structure of typical mollipes , nearly, shorter 
and more robust. Yertex shorter, especially in the males, 
where it is shorter than the pronotum and with a strongly 
depressed disc. Length, ? 6.7 mm., $ 5 mm. 
Color; bright greeD, the anterior part of pronotum and vertex 
pale yellow, often washed with green. The males usually have the 
frontal sutures, ocelli, and tip of vertex, dark, and any or all of the 
spots of the preceding variety may be present. Face and below 
from smoky brown in the females to black in some of the males. 
Specimens that have been referred to this variety are at 
hand from Florida, Mississippi, Texas, Arizonia, California, 
and Mexico, and forms intermediate in structure, but with 
the black face from points as far north as New York. This 
is the commonest form in the Southern states along the 
Gulf, and in California and Mexico, while on the other 
hand the females from Yancouvers Island and Cuba have 
the longest heads seen.

Tettigonia angulifera , Walk. Horn op. Ill, p. 771, 1851. 
Form and color of mollipes , nearly, much larger with a

Vertex broad, slightly sloping from the elevated pronotum, disc 
concave in front, the lateral margins straight, length slightly less
