Megilla macitlata De G. Havana, April i, 7. 



The common red coccinellid beetle, with black spots. It hiber- 

 nates in the adult form, often being found in large numbers in 

 sheltered spots. Very scarce in the bunch-grass in summer, and not 

 many specimens were found hibernating. Next to Coccinella p-notata 

 it is probably the most common species of the family in the east- 

 central states. The food of the Coccinellidae consists chiefly of 

 plant- and bark-lice, and in summer the beetles are found exploring 

 every stem of the plants. 



Hippodamia parenthesis Say. July 19, April i. 



One of our most abundant ladybird beetles, being very commonly 

 found with Coccinella p-notata. These species, with Megilla macu- 

 lafa, are the three that take most readily to cultivated crops. They 

 are more abundant in the cultural and ruderal situations of the 

 sandy loam flats and the roadsides than in the native bunch-grass. 

 In the summer the species was not infrec[uent in the growth of 

 Cassia in the blowsand of the lee slope of blowouts. 



Hippodamia glacialis Fab. April i. 



Very much less frecjuent than the other species. It is probable 

 that the species is to some extent typical of dry or sandy localities. 



Coccinella noveui-notata Herbst. July 19, April i, 4, 5, 7. 



Commonest species of the family, especially in cultivated areas. 

 It is usually found with Hippodamia parenthesis. In the bunch- 

 grass it was common on the Cassia growth on lee slopes of blow- 

 outs. One was being eaten by a reduviid, Zelus socins. Much more 

 abundantly found in spring, hibernating under boards or between 

 lobes of cactus. 



Adalia hipiinctata Linn. July 26. 



Taken in street of Havana; one specimen. The species has only 

 recently become abundant in this state, having been introduced by 

 commerce. 



Chiloconis hivulnerus Muls. June 25. 



Hibernates in the adult stage. Not an abundant species. Taken 

 on grass plant at the Devil's Hole. 



Languria hicolor Fab. June 28, July 29. 



An elongate shining beetle of the family Brotylidae. Occurs on 

 the stems and leaves of Cacalia atriplicifolia h., in the stems of 

 which the larva; live.
