 283 ; ibid. II, 339. 

 Elongate, convex, subcjiindrical. Daili reddisli-browu, shining; au- 

 teniue and legs reddish-yellow. Third joint of, anteuufe one-half longer 

 than second. Thorax one-third longer than wide, broadest near apex ; 

 tubercles on sides not prominent, median line very distinct; surface con- 

 vex, shining, marked with minute scattered punctures. Elytra with two 

 shallow Impressions near middle ; intervals nearly flat, almost smooth, 

 length 7-7.5 mm. 



Throughout the StaU' ; rather scarce. April 21-October 18. 

 Occurs on leaves and about roots of slrunli cabbage. The more con- 

 vex, shining and sparsely punctured thorax, Avider in front, and the 

 smoother intervals of elytra readily distinguish this from faviprx. 



II. H.TfMONiA Lat. 1820. (A geographical name.) 



This genus is represented by a single species resembling Donacia 

 in form, but distinguished by the narrow tarsi and the distinct spine 

 at outer angle of tips of elytra. 



2040 (6549). H^monia nigeicornis Kirby, Eauu. Bor. Amer., IV, ls:;7, 

 222. 

 Elongate, slender, subcouvex. Thorax, elytra and legs brownish-yel- 

 low ; head, auteuna;, tarsi and under surface black. Thorax subquadrate, 

 constricted at middle, front angles rounded, prominent ; surface smooth, 

 with a few coarse punctures at base. EJytra each with ten long rows of 

 punctures and a shorter sutural row ; alternate intervals wider and sub- 

 convex. Length 5.5-8 mm. 



Lake County; scarce. ]\Tay 20-i\ray 28. Taken from pond- 

 weed {T'diamogiJon) in the Calumet River near Pine; also in the 

 washup of Lake ]\Iichigan. Probably occurs in lakes and streams 

 throughout the northern half of State. 



Tribe II. SAGRINI. 



Small or medium-sized, oblong or elongate, roughly punctured 

 species having the head prominent, not narrowed behind; eyes very 

 convex, entire; antennas filiform, rather widely separated at base; 

 thorax not wider than head. Elytra entire, wider tlian tlmrax, 

 strongly and irregularly punctured; front coxa' C(mieal, transverse, 

 usually prominent and contiguoris; middle and hind coxje narrowly 

 separated ; tarsal claws (in our species) toothed or cleft. 



The principal paper treating of the genera comprising both this 

 tribe and tribe IV, CUytlirini, is by 



Born. — "Studies in Chysomelida"," in Trans. Amer. Ent. Soc, 

 XIX, 1802, 1-18. 



Three of the four known genera are represented in the State.
