SUBFAMILY II. — COREIN^. 



239 



form a thin oval plate, fourth fusi- 

 form, shortest. Pronotum strongly 

 declivent, its apex one-half the width 

 of base; humeri with front and hind 

 margins toothed, the tip ending in a 

 short acute spine; posterior side mar- 

 gins smooth, basal one feebly concave. 

 Length, 11 — 14 mm.; width, 3 — 4 mm. 

 (Fig. 49). 



Found throughout Indiana but 

 nowhere common ; April 5 — Nov. 

 5. Occurs usually singly on 

 flowers and foliage of jersey-tea, 

 milkweed and various plants 

 along fence rows, margins of 

 thickets and roadsides. On Sept. 

 29 it was once taken in some 

 pig. 49, x s. (Original). numbers from tall grass and 



dwarf willows along the edges of a wet prairie in Vigo County. 

 Dunedin, Caxambus and Cape Sable, Fla., Nov. 19 — March 21. 

 At Cape Sable it was taken in March by sweeping herbage in 

 a cocoanut grove near the edge of the ocean beach ; while about 

 Dunedin it occurs in spring on low shrubs in open pine woods. 

 It is recorded from a dozen or so stations in southern Florida 

 and probably occurs sparingly throughout the State. The 

 specimens from Cape Sable and other points are smaller, 

 darker, the sides of pronotum with fewer denticles and the 

 humeral spine slightly longer than those from Indiana, and 

 perhaps indicate a southern race. The nymph of the last instar 

 is a very curious echinose creature; the head, pronotum and 

 margins of the entire body being armed with numerous long 

 forked or serrate spines. 



The known range of C. antennator extends from Staten Island, 

 New York and New Jersey, west to Michigan and Colorado and 

 south and southwest to Florida, Oklahoma and Texas. The 

 types of Fabricius were from "Carolina" and he mistook the 

 antenniferous tubercles for joints and described the second 

 joint of antennae as being scabrous and the fourth as clavi- 

 form. This caused Say (I, 323) to describe it anew as Gonocerus 

 ditbius, a synonym. Uhler (1877, 405) says that: "It often 

 occurs upon bushes in the Atlantic region in localities adjoin- 

 ing open woods, and about groves of trees in the low meadows.
