THE STATE ENTOMOLOGIST. 155 



Subsequently I was informed that the seed-corn in other fields in 

 Bergen county, New Jersey, was being destroyed in the same manner. 

 The cause of this destruction is a footless maggot, measuring 0.25 to 

 0.30 of an inch in length, of a yellowish- white color, blunt at the pos- 

 terior and tapering at the anterior end. It is a new foe to corn, and? 

 it is to be hoped that it is confined to the localities above mentioned. 

 In order that it may at once be recognized, I give the following brief 

 account of it : 



This maggot is shown, enlarged, at Figure 86 «, the hair line un- 

 derneath giving the natural size. It greatly re- 

 sembles the Onion maggots, which are known to 

 attack the onion in this country, and its work on 

 corn is similar to that of this last named maggot 

 on the onion ; for it excoriates and gnaws into 

 the seed-corn, as shown at Figure 87, and finally 

 causes such seed to rot. 



After having become full fed, these maggots usually leave the ker- 

 nels for the surrounding earth, where they contract into smooth, hard, 

 [Fio-. 87.] light-brown pupag, of the size and form of Figure 



86 &, and in about a week afterwards the perfect 

 ily pushes open a little cap at the anterior end, 

 ind issues forth to the light of day. In this state 

 it is a two-winged fly belonging to the order 

 Diptera, and quite inconspicuous in its markings 

 and appearance. Though I bred but two females, and this sex fails 

 to exhibit some of the most important generic characters, yet there is 

 nothing in the females of this species to distinguish it from the genus 

 Anthom.yia proper, of Meigen, as restricted by Macquart, and this 

 Corn maggot, therefore, belongs to the same genus as the imported 

 Onion fly (Anthomyia ceparum, Meigen). Upon submitting a speci- 

 men, for inspection, to Dr. Win. Le Baron, of Geneva, Illinois, who 

 has paid especial attention to our two-winged flies, he informed me 

 that it is distinct from any hitherto described North American species, 

 and I have, therefore, called it the Corn Anthomyia (Anthomyia 

 seas). 



Anthomyia zeas $, N. Sp. (PI. 2, Fig. 24). Length 0.20 ,- alar expanse 0.38. Antennae black; 

 style mircoscopically pubescent ; front, fulvous, with a distinct, rather narrow, brownish, cinere- 

 ous margin ; face and orbits brownish-white ; palpi and proboscis black ; ocellar area somewhat 

 heart-shaped ; thorax and abdomen pale yellow-brownish cinerous/ with minute black points at the 

 insertion of the bristles ; thorax with an indistinct middle stripe of brown ; legs black, tinted with 

 cinereous ; poisers pale orchre-yellow ; scales small, the upper valve larger than the lower. 



It is difficult to suggest a remedy for this pest, as its presence is 

 not observed till the mischief is done. Hot water has been found ef- 

 fectual in killing the Onion maggot, without injuring the onions, and 

 would doubtless prove as effectual for this Corn maggot, where a few 

 hills of some choice variety are attacked, which it is very desirable to 

 save. But its application in a large field, even if one knew where to 

 apply it, would be impracticable, and 1 can only suggest soaking the
