Sanderson, Mr. Wnj. Beutenmiiller, Professor Carl F. Baker, Dr. 

 A. D. Hopkins, Mr. Ericli Daecke and others for the loan of 

 numerous specimens: to Mr. C. S. Spooner and AFr. H. J. Ham- 

 mond for assistance with the manuscript. 



The figures of wings on Plates XI-XV inclusive were made as 

 follows: the wings were removed from the right hand side of the 

 insect, mounted on slides and then photographed. Blue-prints were 

 made on drawing paper coated with blue-print solution. The out- 

 lines of the veins were then drawn on the print with water- proof 

 India ink, and after thorough drying the print was bleached in a 

 strong solution of potassium oxalate, leaving the ink drawing on a 

 white background. Thus almost mechanical accuracy was obtained 

 in the representation of the thickness and position of the veins. 

 Figs. 67, 82 and 87 were co})ied by a similar method from published 

 figures, inasmuch as no specimens of these genera were available. 

 Figures 18, 19, 62, 63 and 64 were drawn free hand. The remain- 

 ing drawings were made with a camera lucida. The drawings on 

 Plates Vn and VHI were all made to the same scale, as were those 

 on Plate IX. The claws on Plate IX were mounted on slides, 

 hence present a somewhat different appearance from what would be 

 seen in situ. Plate V is from direct photomicrographs. 



I have been able to study specimens of all the described genera 

 except the following: Evanisciis Szepligeti, Evaniellus Enderlein, 

 Anlacinus Westwood, iSeinenoivia Kieffer and Aulacus Jurine ; also 

 of all the North American species of Aulacinse and Evaniin?e 

 except Hyptia brevicalcar Kieffer, Aulacus erythrogaster Is.\effer, 

 Pristaulacxis flavipes Kieffer. 



The Evaniidae are an anomalous family of parasitic Hymenop- 

 tera, probably of very ancient stock, and as is often true in such 

 cases, although well represented in number of species, the individ- 

 uals are almost invariably to be counted as rare insects, and are not 

 usually well represented in collections. Because of their anomaly 

 they have formed, as I have before remarked, a dumping ground 

 for very many peculiar forms whose relationships have puzzled 

 investigators. In this way the following genera and perhaps others 

 have at one time or another been included in the family, in addition 

 to those we at present include : Felecinus, Stephanus, Mcgischus, 

 Paxilloma, TrUjonalys, Monomachus, Ophionellus, Meyalyra, Capi- 

 tonius, Ccenoccelius, Leptofcenus, etc. To-day most authors are
