in the side near base. As 83 parasites issued from these 36 hosts, it is 

 evident that in the majority of cases more than 2 came from a single 

 host, using a common exit-hole." 



Additional records obtained for 45 hosts from which more than one 

 parasite issued showed that but 5 or 11 per cent, made their exit 

 through more than one hole ; the remaining 89 per cent, emerged 

 through single exit-holes. The hosts in this case averaged about three 

 parasites apiece. 



The position of the exit-hole varies. They may involve the micro- 

 pyle of the host egg, or be near the base, but as stated are generally 

 in the upper half of one side, or near the middle of the side. Their 

 shape varies from small, almost perfectly round holes just the size of 

 the parasite's body, to large, irregular, jagged ones, but is normally a 

 mean between these two extremes. Exceptionally, an exit-hole may 

 involve the whole of one side of the host egg. When the parasites 

 issue from a single host through several holes, usually 2, they are as a 

 rule smaller and round, and in the upper side of the egg. They may 

 or may not adjoin, for instance may be on opposite sides of the host, 

 or all grouped together at the micropyle but separated one from the 

 other. Their method of issuing from the eggs of Alabama argillacea 

 Hiibner is about the same. 



^^ Brachypterous'' speci))iens. — Riley (1885) in writing of this 

 species mentions what he probably supposed to be true brachypterous 

 specimens, but which must have been very recently emerged ones, which 

 have the wings folded in dark squares over the back. On June 30, I 

 noted this to be the case with two males and five females issuing at 2 

 p. M., and in the autumn, many recently emerged specimens were found 

 with the wings in that condition. Naturally at that time of the year they 

 would be noticed more for the reason that it took a much longer time 

 for them to spread. A single "short-winged" female was captured 

 just as it issued from an egg of Alabama argillacea Hiibner on a cotton 

 leaf, at II A. m., October 23, 1904. The wings were unspread and 

 folded so as to " resemble paddles" (Riley, 1885). It was taken to the 

 laboratory and confined in a small glass vial, but up to 6 p. m. had 

 not changed. However, on the following morning, it was found with 

 normally spread wings. Two specimens issuing on the morning of 

 November i had their wings similarly folded and which became 

 normal by the following morning, and this was repeated in the case 

 of numerous specimens emerging on the morning of November 4.
