NOTES ON THE ODON AT A— KENNEDY 



115 



along the sterna from segment 2 to segment 9. This stripe does not 

 show in the drawings, because of the shape of the abdomen. The 

 pleural or upper series is much more interrupted. The spot on 

 segment 1 probably belongs to the sternal series. The accompany- 

 ing text figure shows the application of the terms used in describing 

 these series of spots. I might note here that figures 30-57 were 

 drawn from dried material 14 months old, but excellently pre- 

 served. I believe that the coloration is substantially the same as 

 in life, but I have noticed, particularly in two steamed specimens, 

 some slight changes in coloration. 



The segments of the abdomen in the male (see figs. 30-43) show 

 always the following yellow markings: 



Segment 1. A lateral, vertical, elliptical spot. 



Segment 2. A large, round, posteropleural spot; a large, pear- 

 shaped, anterosternal spot; a large, L-shaped, posterosternal spot, 

 the angle of which runs do-wm onto the genital lobe; a narrow band 

 around posterior end of segment. 



Segment 3. Anterosternal spot large, triangular, confluent with 

 the long, narrow, posterosternal spot. 



Segment 4. No pleural spots. Sternal spots narrow and con- 

 fluent. 



Segments 5-8. A small, round, anteropleural spot next spiracle. 

 Sternal spots confluent, forming a streak along ventral edge. 



vSegments 9 and 10. Sternum yellow. Appendages black. 



Figures 30-43 show the variations in the abdominal markings of 

 14 males. Because of the shape oi the abdomen, the sternal mark- 

 ing of segments 4-8 does not show, but except for slight variations 

 in width ol this sternal strip©, it is for all specimens, both male and 

 female, as described above. 



Pile on abdomen short, scanty, and yellow. 



Figures 26-29 show the variations in the abdominal append- 

 ages in the male. This variation is slight as compared with the 

 other variations in the male. The tips of the superior appendages 

 in life are elastic, and so they frequently vary in their position and 

 direction of curve from having dried while forced out ot shape. The 

 differences shown in the tips of the four figures are due to this dis- 

 tortion in drying. 



The following condensed table gives the measurements in the 

 males :
