nervure ; the basal abscissa is straight, oblique ; there are only two 

 transverse cubital nervures ; the first is straight and oblique, the second 

 is roundly curved outwardly ; there is only one recurrent nervure ; the 

 third transverse cubital nervure is curved down, and then runs alono" 

 parallel with the cubitus. Legs black, covered with white hair ; the 

 spurs black. Abdomen black, thickly covered with long white hair ; 

 the apes of the second, the third entirely and the others more or less 

 covered with white pubescence ; the pygidium is not defined ; the apex 

 of the segment is depressed, smooth, bare and shining ; the apex trans- 

 verse with the sides broadly rounded ; the hypopygium has the apical 

 half smooth, the basal punctured ; the ventral keel has a small tooth at 

 the apex. The petiole is narrowed at the base, where it projects on either 

 side into an oblique tooth ; it becomes gradually broader to the apex. 



This species comes very near to M. japhia here described ; it may be 

 known from it by the median segment being uniformly reticulated, 

 there being no clear space in the middle at the base ; the wings have 

 a more decided violaceous tinge ; the second cubital cellule is sm.aller ; 

 the second transverse cubital nervure has a much more distinctly round- 

 ed curve, and is more oblique ; it is also a smaller species, and the front 

 is not reticulated. 



Mdtilla japhia, sp. nov. 

 Nigra, dense albo hirsuta ; fronte reticulato, basi metanoto laevo ; 

 alls hyalinjs, apice fere fumatis. $ 

 Length. — 8 mm. 

 Habitat. — Deesa. 



Antennse stout ; the scape thickly covered with white pubescence ; 

 the flagellum with a pale down ; the third joint is not much longer 

 than the second and about one-half the length of the fourth. The 

 front, including the eye incision, is closely reticulated ; the vertex 

 strongly and deeply punctured, except behind the . ocelli, where the 

 punctuation is weaker ; the front and vertex are covered with long 

 white pubescence ; the face is opaque, coarsely alutaceous and covered 

 with long white hair. Pro- and meso-notum coarsely and deeply 

 punctured ; the scutellum is more closely, more rugosely punctured. 

 Median segment reticulated, except in the middle above the top of 

 the apical slope, where it is smooth, except for some irregular, broken 

 keels. Plourse smooth and shining ; the raised middle part of the meso- 

 notum coarsely punctured. Legs thickly covered with white hair ; the
