."<; FAMILY III. CURCULIONIDJE. 



50 (S207). EUGXAMPTUS COLLARIS Fab., 1801, II, 410. 



Color variable as shown below; elytra blue-black, abdomen black. Beak 

 carinate at base in male, sparsely and coarsely punctate. Thorax as wide 

 as long, widest at middle; disc coarsely, rather sparsely and irregularly 

 punctate and with a shallow median depression on basal half. Elytra not 

 distinctly striate but the intervals each with a fine carina near the row of 

 large punctures and also with a row of much finer more distant seta- 

 bearing punctures external to the large ones. Length 3.5 4.7 mm. 



Frequent throughout Indiana; May 21 July 13. Bealcn 

 from oak, walnut, butternut and hickory and swept from low 

 herbage along roadsides and the borders of woods. On hickory 

 in June and July near New York City. Ranges from New Eng- 

 land to Michigan and Iowa, south to Florida and Texas. 



Four color varieties are recognized by Tierce, three of which 

 have been taken in Indiana. The fourth, ruficrps, seems to be 

 confined to Texas and to deserve specific rank. 



KEY TO COLOR VARIETIES OF E. COLLARIS FAB. 



a. Thorax black. 



1). Entirely black except elytra; head often with reddish frontal spot; 

 usually female. 50-a. XIGRIPES Melsh. 



t>&. Body black, elytra bluish-black, legs reddish-yellow; both sexes in- 

 cluded. 50-b. FUSCIPES Pierce. 



art. Thorax reddish-yellow. 



c. Head black with reddish frontal spot; elytra bluish-black; legs pice- 

 ous or reddish-yellow; usually female. 50-c. COLLARIS Fab. 



cc. Head, legs and antennae reddish-yellow; elytra bluish-black; both 

 sexes included. 50-d. RUFICEPS Pierce. 



51 (8206). EUGNAMPTUS ANGUSTATUS Hbst., 1797, 140. 



Head, thorax, prosternum and legs usually yellow, elytra dark brown 

 or piceous, antennae piceous. Head and beak rather finely and sparsely 

 punctate. Thorax semi-cylindrical, about as wide as long, disc finely and 

 sparsely punctate and with a short median impressed line. Elytra sculp- 

 tured as in collaris. Length 3.7 4.2 mm. 



Lake, Starke, Kosciusko and Marion counties, Indiana, 

 scarce; June 7 July 4. Toronto, Ontario. Abundant near Xe\v 

 York City in May, June and July, on hickory leaves. Range 

 more northern than that of coUaris. The status of this species 

 is as yet uncertain. LeConle i 1ST*!, <| states that rullaris "may 

 be a dimorphic form of <nt(/iix/<itiix ;" if so the former name has 

 iii-iority. It is possible that mnjiixhitnx is the male of coUaris, 

 with the piceous color of elytra a characleristic of norlli'M-n spe- 

 cimens.
