body beneath, and legs are black; and the wing-covers are not so square 

 behind as in the rosy Hispa." (PI. VIII, fig. 3.) 



The Larva. 



The larva has been briefly characterized by Dr. Fitch as — "a small,, 

 flattened, whitish worm, attaining a quarter of an inch in length, taper- 

 ing from before backwards, with projections along each side like the teeth 

 of a saw, and with only three pairs of feet, which are placed on its breast; 

 eating the parenchyma and leaving the skin of the leaf entire." 



Parasites. 



Several species belonging to the large parasitic family of Chalcididcz 

 have been reared from this insect by Dr. Riley, and described at his 

 request by Dr. Howard. Spilochalcis \^Smicra\ odontotce Howard, was 

 reared from the pupa of this locust feeder. Sympiezus iiroplatcj^ Howard 

 feeds externally on the larva within its mine. Trichogratiwia odontotce 

 Howard, is an egg parasite issuing in July. Derosienus primus Howard 

 MS., was reared from the leaf mine of Odontota. Dr. Howard thinks it 

 may be a secondary parasite, preying upon either of the first two 

 species {loc. cit). 



Distribution. 



Dr. Horn has given the distribution of this insect as, " Middle and 

 Southern States." Dr. Packard records it from New England, Middle 

 and Western States. Prof. Webster has mentioned defoliations by it 

 (more or less complete) in southern Ohio and adjacent parts of 

 Kentucky.
