sidered them as chordotonal organs. The present writer (50, 51) 

 made a thorough study of the disposition and structure of them in 

 many Lepidoptera and their larvae. Priiffer {^j) has most recently 

 described these pores on the wings of certain moths in connection with 

 the antennal organs. 



The olfactory pores on five male and five female codling moths 

 were counted. Female no. 3 was examined most carefully and conse- 

 quently the greatest number of pores was found on it. In figures 4 

 and 5 they are represented by black dots. The groups are numbered 

 from I to 12. The isolated pores which are constant in position are 

 designated by a to c, the others not being thus marked. Groups i to 6 

 and pores a and h lie on the wings (fig. 4) ; groups 7 to 11 and

pores c and d on the legs (fig. 5, A) ; group 12 on the base of the 

 labial palpus (fig. 5, E) ; and pores e (fig. 5, D) on the maxilla (one- 

 half of proboscis). The number of pores in the groups follows: 

 No. I, 91 ; No. 2, 70; No. 3, 52; No. 4, 12; No. 5, 129; No. 6, 52; 

 No. 7, 4; No. 8, 4; No. 9. 5; No. 10, 4; No. 11, 7; and No. 12, 8. 

 The total number counted on female No. 3 follows : Legs, 191 ; front 

 wings, 462; hind wings, 417; proboscis, 28; labial palpi, 16; and 

 second segments of antennae, 4; making 1,118 in all. The total 

 number of pores on males range from 933 to 1,049, with 986 as an 

 average ; and on females from 960 to 1,118, with 1,029 ^^ an average. 

 Figures 6 to 8 represent the internal structure and innervation of 

 the pores and sense hairs, and also the internal anatomy of the wings 

 and legs where the pores are found on them.
