LXXIII. AMPHioNYCHvLec. 1852. (Gr., 1 1 on both sides .+ claw. 



This genus comprises two small species having the antennae 

 strongly pilose, the third and fourth joints elongated, outer joints 

 suddenly shorter; eyes not divided; tarsal claws cleft. One of the 

 two occurs in Indiana. 



2021 (6516). Amphiontcha flammata Newm., Entom., 1840, 13. 



Elongate-oblong. Black, feebly shining; hispid with fine, erect, black 

 hairs; vertex of head, a stripe each side of thorax, and often the margins 

 of elytra nearly to apex, yellowish; outer joints of antennae feebly annulate. 

 Thorax rather finely, elytra more closely and coarsely, punctate. Length 

 6-9 mm. 



Kosciusko County; rare. July 11. Probably occurs throughout 

 the State. In the specimen at hand the elytra are wholly black. 



Tribe X. METHIINI. 



While no member of this tribe has as yet been taken in the State, 

 one, Dysphaga Uevis Lee, probably occurs, having been described 

 from Illinois. It is a small black or piceous species, with thorax 

 cylindrical and elongate ; elytra a little more than half the length of 

 abdomen, narrowed and dehiscent behind the middle, their tips 

 rounded, surface roughly punctate ; legs yellow. Length 7 mm. It 

 is supposed, like allied species, to breed in hickory twigs. 



Family LILT. CHRYSOMELID.F. 

 The Leap Beetles. 



A very large family of medium- or small-sized beetles, usually 

 short-bodied and more or less oval in outline, with the antennae of 

 moderate length, usually filiform, the joints often comparatively 

 stouter towards the tips. In color the beetles are often prettily 

 variegated, though some are wholly of a brilliant metallic blue or 

 green, while others are dull black or brown. All have the legs short, 

 with the tarsi of the same type as in the Cerambycidaf, viz., the 

 fourth and fifth joints grown together, the fourth usually very 

 small and concealed in a notch in the third segment. (Fig. 498.) 



In addition to the general characters above given, the species 

 agree in having the labial palpi 3 -jointed; mentum transverse and 

 not large; maxillary palpi 4-jointed, cylindrical, rarely dilated or 

 elongate. Head either prominent and more or less constricted be- 

 hind (Eupoda) or inserted to the eyes; in the Cassidini usually con- 

 cealed under the shield-like thorax ; eyes entire or feebly emarginate
