 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 Leiig by including the single genus 

 Psyllohora of the tribe Psylloborini and combining certain genera 

 with Ciiccinella. This gives in onr fauna representatives of five 

 genera.

Rounded, very convex fonns havinir the front margin of the tho- 

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

 markings of thorax and eh'tra. and among them are scime of the 

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

 usually defined, was divided by (^'asey into four. viz.. CixeiiKlla. 

 XcolMrmonw. Ciuloncda and 011a. and to them he ascribed 27 

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

 to 12. Of these the foUo\A"ing are Icnown from the State :
