KEY TO THE INDIANA GENERA OF HALTICINI, SUBTRIBE A. 



a. Last joint of hind tarsi globosely swollen (Fig. 515, a) ; punctures of 

 elytra confused; surface glabrous; thorax very little narrower than 

 elytra. I-'- <Ei>iONYrms. 



mi. Last joint of hind tarsi not inflated, usually slender, sometimes thick- 

 ened when viewed from the side. 

 b. Mesosternum always visible, usually moderately long. 



c. Thorax without a transverse impression near the base ; hind tibiae 



faintly or not grooved. 



<l. First joint of hind tarsus short, as compared with the tibiae, and 



rather broad; claws appendiculate (Fig. 515, b) ; size medium, 



4.5 or moiv nun. LII. DISONYCHA. 



(hi. First joint of hind tarsus long and slender; claws simple; size 



smaller, less than 4 mm. 

 e. Hind tibiie grooved above or on the outer edge, at least near 



apex; elytra without yellow stripes or spots. 

 /'. Hind tibine with the apex entire, the spur placed in the mid- 

 dle in front of the tarsus. 



!/. Punctures of elytra confused; first joint of hind tarsus 

 nearly or quite as long as half the tibia (Fig. 515, c). 



LIII. LONGITARSUS. 



(/(/. Punctures of elytra in regular rows; first joint of hind 

 tarsus not more than one-third the length of the tibine 

 and scarcely as lung as tlic Iliree following joints united. 



LIV. GLYPTINA. 



//. Hind tibiie deeply grooved above, with the apex notched or 



bilobed, the spur placed on the outer lobe ; reddish-brown, 



shining. LV. APHTHONA. 



ec. Hind tibite not grooved on the outer edge, slightly excavated 



near the tip, the spur at middle beneath ; elytra each, usually 



with a yellow stripe or spots. LVI. PHYLLOTRETA. 



ce. Thorax with a transverse impression on basal half. 



li. Transverse impression of thorax usually feeble, not distinctly 

 limited at each end; elytral punctures, when present, confused. 

 /'. Hind tibia? each with a short terminal spur. LVII. HALTICA. 

 it. Hind tibite wholly without spurs. LVIII. LUPERALTICA. 



lilt. Transverse impression deep, limited at each end by a longi- 

 tudinal fold; above bicolored. 



./'. Elytra nearly smooth, the punctures, when present, extremely 

 fine and scattered. LIX. LACTICA. 



jj. Elytra with distinct punctures in rows. 



/.-. Form oval ; surface without erect hairs. DIPHAULACA. 



/,/,. Form oblong, parallel; elytra with short hairs arising from
