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 

 O mollipes. There is nothing in Walker's description to 

 indicate this, and the spots oii vertex and scutellum are 

 about equally common in Var. iniiior. Many specimens of 

 ty\)icnl^)iollipes 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.

Tet/igonia minor, 'Wa]k. Homop. Ill p. 772. 1851. 



Form and structure of typical mollipes, nearly, shorter 

 and more robust. Vertex shorter, especially in the males, 

 where it is shorter than the pronotum and with a strongly 

 depressed disc. Length, 9 6.7 mm., $ 5 mm. 



Color; bright green, the anterior part of pronotum and vertex 

 pale yellow, often washed with green. The males usually have th& 

 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 Vancouvers Island and Cuba have 

 the longest heads seen.

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 les&
