the characteristic skeletonizing of the leaf are shown at c, while a mag- 

 nified lateral view of the larva is given at d. Fig. 36 represents a leaf 



eaten by a fall-grown larva, in 

 which none of the skeletonizing of 

 the earlj^ larval stages is present. 

 Fig. 37 is an enlarged view of the 

 female fly, the natural size being 

 indicated by the hair lines be- 

 neath. The ovipositor, by means 

 of which the sht in the leaf for the 

 insertion of the eggs is made, is 

 shown at h, and the antenna at c.

COCKROACH EGG PARASITES. 



The commonest parasite of the cockroach eigg capsule in Europe is 

 the old Linnaean Evania appendigaster. This insect has been described 

 in different parts of the world under a great many different names, 

 and although an indigene in Europe^ was found in Cuba as long ago as 

 1829. It has also been found in the United States by Br. Packard, 

 Mr. Ashmead, and others. The good which might be accomplished by 

 this important parasite is modified by the fact that it has a destructive 

 secondary parasite, which was described by Eatzeburg in 1852 as 

 Entedon liagenowi. We should indeed be fortunate in this country if 

 the Evania had been imx)orted without its own particular enemy, but 

 in a collection of micro-hymenoptera from the academy of ]N"atural 

 Sciences in Philadelphia, which has been loaned to this Division for 

 study, Mr. Ashmead has found specimens of this Entedon hagenoivi in 

 a lot of Cuban micro-hymenoi3tera sent to Mr. Oresson many years ago 

 by Dr. Juan Gundlach and Prof. Felipe Poey. The larger species of 

 this particular sending were described by Mr. Cresson in his paper on 

 the Hymenoptera of Cuba in the Proceedings of the Entomological 

 Society of Philadelphia for 1865. Mr. Ashmead also informs us that 

 in his old Florida collection he has specimens of the secondary para- 

 site collected in that State. 



THE HYMEXOPTERA OF AUSTRALIA. 



Some two years ago Mr. W. W. Froggatt, of the Sydney Museum, 

 published Part i of his '^ Catalogue of the Described Hymenoptera of 

 Australia," cariying the list through the remarkable family Thynnidae, 

 a group in which the Australian fauna is wonderfully rich, not less 

 than five hundred species having been listed. 



We have recently received from him Part ii of the Catalogue, which 

 is a reprint from the Proceedings of the Linnaean Society of New South
