2142 (6808). Calligrapha scalaris Lee, Ann. Lyc. Nat. Hist, T, 1824, IT:;. 

 Oval, convex. Dark metallic green, shining; elytra 



creamy white with a broad, greenish, common sutural 

 stripe, which projects three short spurs each side, and 

 each with a large, curved humeral lunule double to near 

 middle and enclosing a round greenish spot; behind the 

 lunule 12 to 15 small greenish spots; antennae and legs 

 reddish-brown. Thorax more than twice as wide as long, 

 coarsely and sparsely punctate and with an irregular im- Fig . 501 

 pression each side. Elytra finely, sparsely and irregu- ( After Kn °bel.)' 

 larly punctate. Length 8-10 mm. (Fig. 501.) 



Lake and Laporte counties; scarce. June lG-June 12. Beaten 

 from foliage of linden and elm. 



2143 ( ). Calligeapha rhoda Knab, Proc. Ent. Soc. Wash., XI, 1909, 83. 



Subovate, convex. Dark olive green, submetallic; legs, antenn-e and 



palpi reddish-brown; elytra creamy white, or often with the apical two- 

 thirds dull reddish-yellow ; a common sutural stripe and humeral lunule 

 much as in scalaris, the latter enclosing two small spots which are often 

 confluent; disk behind lunule with about 11 small spots. Head and thorax 

 finely alutaceous, coarsely, sparsely and irregularly punctate, the thorax 

 with an irregular impression each side. Pale area of elytra more coarsely 

 and closely punctate than in scalaris. Length 7-8 mm. 



Lake, Marshall, Marion and Lawrence counties ; frequent, April 

 29-J uly 15. Knab says of it : ' ' This species feeds exclusively upon 

 the hazel, both in the imago and larval stages, and, as far as known, 

 it is the only species of Calligrapha found upon this plant, " It will 

 probably be found throughout the State, wherever hazel occurs. 

 2143a ( ). Calligrapha rhoda walshiana Knab, Mss. 



A variety of rhoda in which the annexed stripe (united with the usual 

 double sutural stripe on median third of elytra) is very slender, less curved 

 than usual and with its front and hind portions directed obliquely forward 

 and backward. Discal elytral spots 15 or 16 in number. Length 7-8 mm. 



Lake County; rare. May 25-June 3. Knab's specimens are 

 from Missouri, and he thinks this may be the form mentioned by 

 Walsh as a variety of 0. scalaris occurring upon the wild plum. 



2144 ( ). Calligrapha rowena Knab, Proc. Ent. Soc. Wash.. XI 



1909, 85. 



Differs from rhoda principally as mentioned in key. In mature speci- 

 mens the greater part of elytral disk is bright orange red, the basal third 

 and broad outer margin golden. Punctuation of elytra distinctly coarser 

 than in rhoda and the surface therefore more uneven. Tarsal claws more 

 divergent. Length 6.5-8.5 mm. 



Marshall County; rare. June 26. Originally described from 

 Canada, New England and Pennsylvania. "While the three forms
