SUBFAMILY II. — CYMIN^E. 



357 



b. Head but slightly declivent in front; eyes almost in contact with 

 front margin of pronotum; width of head across eyes only about 

 half that of hind margin of pronotum; form rather broadly oval. 



I. ISCHNORRHYNCHUS, p. 357. 



bb. Head strongly deflexed in front; eyes well separated from front 

 margin of pronotum; width of head across eyes about that of 

 hind margin of pronotum ; form narrowly elongate. 



II. Cymoninus, p. 359. 



oo. Corium not hyaline, densely punctate throughout; fourth antennal 



shorter than third ; head with a narrow curved longitudinal sulcus 



before each ocellus; scutellum wider at base than long (Tribe 



Cymini Stal) . III. Cymus, p. 359. 



I. Ischnorrhynchus Fieber, 1861, 51, 199. 



Small oval species having the head subcorneal, slightly wider 

 across the eyes than long; antenniferous tubercles short, ob- 

 tuse; antennae longer than head and pronotum, joints 2 and 3 

 slender, 4 stouter, fusiform, slightly longer than third ; bucculae 

 short, scarcely reaching front margin of eyes; beak reaching 

 second ventral ; pronotum bell-shaped, constricted near apex ; 

 clavus with sides parallel, its commissure shorter than scu- 

 tellum ; elytra covering the abdomen, much surpassing its tip ; 

 margins of osteolar duct slightly prolonged, their tips sub- 

 acute. Males with genital plate oval, convex. Other characters 

 as in key. Van Duzee recognized five North American species, 

 two from the eastern states. These are 

 in my opinion synonyms, but one of his 

 southwestern species occurs in Florida.
