lady-bug 1 , Cocci ucHa !>-}><>i<il, common in gardens. Most of the 

 species resemble these common forms in si/e and shape, being 

 rounded and convex. The tribe, as divided by Casey, comprises 

 ten North American genera. In order to avoid the division into so 

 many groups I have followed Leng by including the single genus 

 rxijllohont of the tribe Psylloborini and combining certain genera 

 with Coccinella. This gives in our fauna representatives of five 

 genera.

<i. P.o<ly larger, 4-7.5 mm.; antenna 1 shorter with hist joint truncate. 



1>. Antenna 1 only slightly longer than head; epipleura not extending to 



the sutural tip. 



c. Body usually rounded, strongly convex; elytra reddish, without 

 spots or with more than two black spots on each; tarsal claws 

 with a large subquadrate tooth at base. (Fig. 184. c.) 



IV. ( 'OCCINELLA. 



ce. Body oval, less convex; elytra reddish with one or two black spots 



on each; tarsal claws as in Fig. 184, 1). V. ADAI.IA! 



1>1>. Antenna 1 longer, extending at least to middle of thorax; epipleura 



entire. 



(I. Tarsal claws bifid (Fig. 184, a.) ; prosternal process compressed in 



front; elytra without spots. VI. NEOMYSIA. 



del. Tarsal claws as in Cocriiidla ; prosternal process broad, strongly 



convex in a transverse direction and prominent at apex; elytra 



with numerous spots. VII. ANATIS. 



mi. Body small. 2-2.5 mm.: antenna- slender with last joint elongate. 



VIII. PSYLLOBORA. 



IV. COCCINELLA Linn. 17f>S. (Gr., "scarlet - insect,") 



Rounded, very convex forms having the front margin of the tho- 

 rax more or less emarginate. They vary considerably in the black 

 markings of thorax and elytra, and among them are some of the 

 most common and best known of the "lady-bugs." The genus, as 

 usually denned, was divided by Casey into four, viz., Coccinclla, 

 Neoharmonia, Cjjcloncda and OUa, and to them he ascribed 27 

 species. Leng reunited the four and reduced the number of species 

 to 12. Of these the following are known from the State :

at each apical angle, pale. 



It. Elytra together normally with nine spots, without trace of sub-basal 



crossbar. 078. O-NOTATA. 



bl>. Elytra with three black crossbars, the one near base common, the 



others interrupted at suture. 971>. TRIFASCIATA.
