He also recorded a species of Eurytoma (Mally, 1902). In 1904 Hunter and Hinds recorded additional pri- mary parasites as follows: Sigalphus curculionis Fitch (), Catolaccus incertus Ashm., IJr'osigalplius (robustus Ashm.), Bracon {dorsator Say), and Eurytoma tylodermatis Ashm., as well as an ento- mogenous fungus, Aspergil- lus sp. (Hunter and Hinds, 1904, pp. 104-110). The determination of tliis Uro- sigalphus has been found incorrect. It has just been described as Urosigalphus anthonomi Cwfd. (Crawford, 1907a). The form known under the name of Bracon dorsator is merely a small, melanistic, fall form of Bracon mellitor Say. Finally, Banks has described a mite, Tyroglyplius hreviceps, collected at Victoria, Tex., from boll weevil larvse (Banks, 1906, p. 17). THE WORK ON PARASITES IN 1906. As the work of the year naturally divided itself into distinct sec- tions,- it may be thus divided for treatment in this report: I. Examination work—ascertaining the general status of boll weevil parasitism. II. Propagation work—attempting to increase the percentage of parasitism by release of parasites. III. Breeding work—study of the biology of the parasites. IV. Source work—study of the surrounding field conditions in order to ascertain the hosts which have contributed the parasites, and to learn the biology of each of these hosts. V. Conclusions—a review of the situation as a Fig. Z.—Sigalphus curculionis: a, male; b, female; c, antenna.
