THE LA MEL L [CO TIN BEETLES. 



985 



Lake and Vigo counties; rare. June 27- July 7. Of the Vigo 

 County specimen my notebook says, ''several buzzing close to 

 ground in cornfield on high land southwest of St. Mary's — only one 

 taken." This specimen, together with the one since taken in Lake 

 County, have heretofore been among my innuba labeled as a variety, 

 but a critical examination shows the form of clypeus, cleft of tarsal 

 claws, pubescence of under surface and punctuation of elytra to be 

 wholly different and presenting a combination of characters found 

 in no other described North American species. 



1841 (5838). Anomala lucicola Fab., Erit. Syst, 1798, Suppl. 132. 



Oval, robust. Color variable from entirely dull yellow to wholly black ; 

 thorax often with a discal piceous space, this sometimes divided at middle. 

 Clypeus nearly twice as broad as long, rather densely punctured, its front 

 broadly rounded, sides very little divergent, margin narrowly reflexed. Tho- 

 rax convex, sides regularly curved ; surface rather coarsely but not densely 

 punctured. Elytra with double rows of rather coarse, closely placed punc- 

 tures, those near the suture confused ; intervals broad, feebly convex, finely 

 punctulate. Length 8.5-10 mm. 



Throughout the State ; frequent in the southern counties, much 

 less so in the north. June 12-July 11. Occurs most commonly on 

 the foliage of the wild grape and Virginia creeper. Sometimes does 

 much damage to cultivated grapes. These can be sprayed with a 

 solution of Paris green, as the poison will be washed off between 

 the time of the beetles' appearance and the ripening of the fruit. 



1842 (5840). Anomala makginata Fab., Ent. Syst, I, 1798, 164. 



Oval, robust. Pale dull yellow, with shining bronzed lustre ; head and 

 disk of thorax reddish-brown, narrow side margin of latter paler. Clypeus 

 short, broader at base, margin narrowly reflexed, its surface and lower 

 part of front densely and rugosely punctured. Thorax narrower in front, 

 sides curved, surface rather coarsely and sparsely punctured, with minute 

 shallow punctures between the larger ones. Elytra with somewhat irregu- 

 lar rows of coarse, closely placed punctures, the intervals equally convex. 

 Length 12-15 mm. 



Knox, Crawford and Posey counties; scarce. June 25-July 10. 

 Our largest, least variable and most handsome form. A member of 

 the Austroriparian fauna which, according to Horn, "occurs in the 

 Southern States." 



XXV. Strigoderma Burm. 1844. (Gr., ' ' stria + skin.") 



This genus differs from Anomala mainly by the characters given 

 in key. The thorax is impressed on the sides and the outer front 

 and middle tarsal claws are cleft at tip.
