SUBFAMILY V. APIONINJE. 71 



Described from Massachusetts, District of Columbia and Port 

 Huron, Midi. The males have the femoral tubercle prominent 

 and rounded and the front tibia 1 strongly dilated. 



72. (8379). APION MELANARIUM Gei'st., 1854, 261. 



Elongate, slender. Black, shining, elytra often with faint brassy 

 lustre; antennas and legs piceous; pubescence very sparse and inconspic- 

 uous. Beak of male scarcely longer than head and thorax, finely sculp- 

 tured and punctulate; of female, longer and more curved, very slender. 

 First joint of antennae subequal to the next two, male; seldom as long as 

 next three, female. Thorax longer than wide, sides feebly diverging from 

 apex to base; disc rather finely, not very closely punctate, its dorsal line 

 almost complete. Elytra narrow, nearly twice as long as wide; intervals 

 nearly flat, about twice as wide as striae. Under surface finely and 

 sparsely punctate. Length 1.7 2.2 mm. 



Not yet recognized from Indiana, though it undoubtedly 

 occurs as it ranges from Canada and New England to Iowa, 

 south to Florida and Texas, and is recorded from Michigan and 

 Illinois. Arlington, N. J., April October. Closely related to 

 Itnnixi/lruniriim but the elytra more narrow and the front femora 

 of male strongly tuberculate, not merely swollen as in that 

 species. 



73. (8374). APION FLORIDANUM Smith, 1884, 49. 



Very narrow. Black, legs and antennae dark rufous, pubescence very 

 inconspicuous. Claws simple, femoral tubercle of male prominent, smooth 

 area rather strongly striate interiorly. Length 2 mm. 



One male found at Capron, Fla. Nearest (Icftolutum in gen- 

 eral appearance, but differs by the evident humeri and stronger, 

 striate femoral tubercle. The unusually stout beak and the very 

 narrow elytra should make it easily recognizable. 



74 (8365). APION ROBUSTUM Smith, 1884, 45. 



Elongate, rather robust. Black, feebly shining; antennae and tibia? 

 piceous; pubescence very fine and sparse. Beak of male as long as head 

 and thorax, finely striate except at tip, minutely punctate; of female, 

 longer, more slender and more strongly curved. First joint of antennae 

 equal to the two following, male, or three, female, the third joint reaching 

 the eye. Thorax subcylindrical, a little longer than wide; disc finely, not 

 densely punctate, the median line deep, complete. Elytra widest and more 

 convex at middle; striae rather fine, their punctures distinct; intervals 

 flat, nearly three times as wide as striae. Length 2.5 2.7 mm. 



Southern third of Indiana, scarce. May May 21. Swept 

 from low herbage. Ranges from Michigan to Missouri and Texas. 

 A. obesuni Smith is the female of robust inn.
