Catnponotus fiutiides var, festinatHs Buckley. 



This species of Camponofus is very abimclant in tlie vicinitj'' of 

 Austin, and is very conspicious on account of its large size and briglit 

 yellow color. The queen is of frequent occurrence and a ditterentiation 

 of tlie reproductive organs of the females forms was exjjected, The 

 queen has between lifteen and eighteen tiibules on each side of tlie 

 ovary, the tnbules are long and slender. and contain fifteen to twenty 

 eggs each. The ovaries of this ant resemble those of C. nian/inafus 

 very much. the only diff'erence noticeable being a small increase in 

 the size of the tnbules. The t y p i c a 1 r e c e p t a c u 1 u m s e m i n i s 

 was present. 



The soldiers have not so many tubules as the queen but their 

 ovaries are well developed and each tubule contains several eggs, 

 some of which in every case were mature. The tubules being fewer 

 in number could be counted readily. The variations were so great 

 that they are given in the following table: 



No receptaculum semin is was present (Fig. Oa). 



The workers showed a greater reduction in the number of tubules, 

 the highest nnmber reached being two on one side and one on the 

 other; only two specimens showed this condition, while thirty possessed 

 a Single tubule on each side, which, however, were well developed 

 and contained normal and mature eggs. Among these thirty-two 

 ovaries two specimens were found with the receptaculum situated 

 in the usual position on the vagina between the tubules (Fig. Ob). 

 Nine specimens- exhibited a very peculiar structure; on one tubule 

 was situated a sac like structure, which had it occupied the usual 

 Position on the vagina would immediately have been recognized as 

 the receptaculum seminis, but owing to its abnormal position 

 its function is not certain (Fig. Oc).
