COCCINELLID^E. 



Tarsi 3-articulate, 2nd joint bilobed ; maxillary palpi with 

 the last joint large, securiform (rarely subcorneal) ; antennas short, 

 with a 3-jointed club, 11 -articulate (very rarely 8 or 10), inserted 

 at the edge of clypeus ; first ventral segment with an arcuate 

 raised line on either side, varying with the degree of mobility of 

 the femora. 



Subfamily 1. Coccinellid^e (Genuinse). 



Anterior coxal cavities closed. 



Tribe 1. Epilachnides. 



Surface pubescent, punctuation uneven, claws nearly always 

 bifid, mandibles multidentate, abdominal plates generally complete, 

 thoracic epipleurse hardly ever foveolate for the antennae. 



The species of this sub-family are phytophagous, and extremely 

 variable in colouration. Then- similarity in form and colouring to 

 the Chrysomelidse is very remarkable, and if these species are 

 endowed with an unpleasant odour and taste, as are the typical 

 Coccinellce, a strong case for " mimicry " might be made out. 



A. Species Americans. 



The American species of this genus sort themselves in certain 

 groups distinguished by their appearance and by their local distri- 

 bution. 1. Metallic species variously spotted with yellow. Typ. 

 E. Proteus. Venezuela, N. Granada, Ecuador, Peru. 2. Rufous 

 species with angular black marks. Venezuela, N. Granada, 

 Ecuador. 3. An assemblage of minor groups, all from Mexico. 



4. The only widely spread species and its allies. E. Borealis. 



5. The convex fulvous species with an ochreous margin divisible 

 into groups by the form of the abdominal plates. Principally from 

 Brazil. 



The species with dilated shoulders, here placed at the beginning, 

 present extreme difficulties in their determination. Mulsant was 

 by way of lumping them all under E. Proteus, but afterwards 

 separated E. patricia and others. The truth appears to be that
