336 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 5 named and described this parasite. The species was reared from cocoons collected in several Iowa localities in the summer of 1910. From cocoons collected in October and kept in the insectary cold room, the adults emerged in March 1911. Mesochorus nigrisignis Yier. This insect, also recently described by Viereck,^ is a secondary parasite on Microplitis melianae. Only two specimens have been reared, one August 8, 1910, the other April 16, 1911. In the latter case the parasite spent the winter in the insec-tary cold room within the cocoon of its host. Omorgus sp. A single parasite, so determined by Mr. H. L. Viereck, emerged May 5, 1911 from an insectary cage in which a number of wheat-head army-worms were placed the October before. It has presumably some relationship to that insect, but what this may be is entirely a matter of conjecture. NOTES ON SAPERDA CALCARATA SAY IN SOUTH CAROLINA By Wilson P. Gee Saperda caJcarata is one of the largest of our native species of the very destructive genus Sapercla, and cases where it has been reported its damage seems to have been of a rather severe nature. The notes available on the life history of this form are exclusively northern or eastern in their application, and since there is a difference in those localities and this of a couple of months in the emergence of the adults, these few observations have been considered as of sufficient value to be made available for general use. On April 20, 1912, investigation was made of a reported outbreak of a poplar borer at Whitmire, S. C, with the result that some 1,200-1,400 handsome Carolina poplars (Populus deltoides Marsh) were discovered to be almost hopelessly infested ^\dth Saperda calcarata Say. The attention of the mill authorities at this place, on whose property the trees were found, was directed to this damage only after several trees had broken off, a distance of some seven to nine feet above the ground. Examination revealed the fact that practically the entire lot of ten-year old trees were in a condition to be similarly mutilated upon being subjected to heavy winds. The distribution of this species is quite general east of the Rockj' Mountains according to Felt (Monograph of the Genus Saperda, New York State Museum, Bull. 74), who reports having seen speci-ilbid, p. 192.
