MEGILLA. 151 



The " Epilachnides," which are numerous in species and individuals in the fauna 

 under investigation, are phytophagous, and remarkably different in their habits from 

 the rest of the Coccinellidse. Some of the species, according to Mr. Champion, are very 

 abundant at times on cultivated Cucurbitaceous plants. 



Subfam. HIPPODAMIIDES. 



The Hippodamiides are an essentially northern group of the Coccinellidse, and 

 although one or two widely dispersed species extend in the New World as far south as 

 the Straits of Magellan, I am not aware of any being found in the Eastern Tropics, 

 Australia, or New Zealand, with one exception, Hippodamia variegata, Goeze, which 

 from its wide distribution has reached India. They are characterized by their oblong 

 depressed form, and by the absence, or nearly so, of the depressed spaces (called 

 " plaques abdominales " by Mulsant) on the first ventral segment for the reception of 

 the femora of the hinder pair of legs.

Megilla, Mulsant, Spec. Col. Trim, secur. p. 24 (1850) ; Monogr. des Coccin. p. 16 (1866) ; Crotch, 

 Rev. Coccin. p. 92 (1874). 



Crotch [Trans. Am. Ent. Soc. iv. p. 365 (1873), and Eev. Coccin. p. 91] has separated 

 three species, two under the generic name Eumegilla and one under that of Cerato- 

 megilla ; as thus restricted Megilla consists of only three species, which are widely 

 distributed in the New World, and are very variable.
