First abscissa of radius a little shorter than second ; second 

 cubital cellule not much narrower in front than behind ; 

 second transverse cubital nervure thickened on the outerside 

 in front. Antennae densely co veiled with short, stiff, black 

 pubescence. 



EVANIID.E. 

 Megischus froggattii, sp.n. 



9 . Black : legs red ; coxae, trochanters, and the narrowed 

 basal part of hind tibiae black ; femoral teeth about the same 

 length, but the basal one much thicker at base than the 

 apical, which is more slender, and of more uniform thick- 

 ness ; shortly beyond it are two short ones, basal a little 

 longer and sharper than apical. A pale yellowish mark between 

 the eyes and the base of the mandibles ; basal joints of palpi 

 reddish. Wings fuscous- violaceous, more deeply tinted in 

 middle than at ba.se or apex; stigma and nervures black. 

 White ring near apex of sheaths of ovipositor as long as the 

 black apical pai't. Length, 31 ; ovipositor, 33 mm. The 

 two males in the collection are only 13-15 mm., in length. 



Abdominal petiole as long as head and thorax united, and 

 a little longer than the rest of abdomen; it is, as usual, 

 closely, transversely, finely striated. Vertex from the hinder 

 ocelli closely, strongly striated, the striae more or less twisted ; 

 there is a smooth space below the ocelli, the sides of this 

 bordered by longitudinal striae ; above the ocellus are five 

 stout, widely separated striae; the lower tubercle is broadly 

 rounded at the apex, flat in the centre, with the sides raised ; 

 the other tubercles are oblique, sharply jointed. Pronotum 

 smooth, the centre with a stoutly, transversely striated band ; 

 the smooth basal part has an oblique, stout tooth on either 

 side of base. Base of mesonotum smooth, except for round, 

 clearly separated punctures, the sides irregularly striated, 

 the space between the striae deep, distinct ; the part border- 

 ing the scutellum bearing large, deep, scattered punctures ;
