being laid by stray beetles, if the tobacco is exposed during the manu- 

 facture of cigars. In order to guard against this, cigars before leav- 

 ing the factory should be fumigated thoroughly in a small room with 

 HON, then aired and packed. This would not cost much but it 

 would practically insure the manufacturer's business. 



The writer knows several parties, who turn out cigars that are 

 free from the pest, although the tobacco was formerly- infested. But 

 by steaming the tobacco the pest was killed and then the tobacco is 

 manufactured in a different town where there are no insects to 

 reinfest. 



If a single beneficial suggestion has been given or if the paper will 

 induce some one to rid their house of the cigarette beetle by means 

 of H C N, or otherwise, the writer feels that the paper has not been 

 in vain. 



For a fuller account of the cigarette beetle the reader is advised 

 to consult Farmers' Bulletin No. 120 of the U. S. Department of 

 Agriculture. 



STUDIES OF THE DEVELOPMENT OF EUPELMUS 

 ALLYNII FRENCH AND STICTONOTUS ISOSOMATUS 

 RILEY 



By E. O. G. Kelly, Bureau of Entomology 



These two valuable parasites have been known to science and ento- 

 mologists for about twenty-eight years. In 1881 and 1882, Prof. 

 Gr. H. French reared adults of what is known as Eupelmus allynii 

 from wheat straw and described the insect as Isosoma allynii. Pro- 

 fessor French and Dr. C. V. Riley discovered that the insect was 

 parasitic on Isosoma grande and that it did not belong to the genus 

 Isosoma. Doctor Riley decided that the species belonged to the genus 

 Eupelmus and it still remains Eupelmus allynii. 



During this same winter of 1882, Doctor Riley reared and de- 

 scribed adults of Stictonotus isosomatis parasitic on Isosoma grande. 



Doctor Riley, Doctor Forbes, Professor French, Professor Webster 

 and many other students of insects affecting cereal and forage crops 

 have reared these parasites from the straw ; and considerable has been 

 written regarding their economic importance, but the larval habits 

 have not heretofore been described. 



The females of these two species have rather long pointed oviposi- 

 tors with which they readily pierce the hard straw containing Iso- 

 soma sp., and puparium of the Hessian fly. The females put their
