not incised, depressed or hooked ; the apical joints of the flagelluni 

 thickened. The transverse median nervure is received shortly 

 beyond the transverse median. Cubitus in hind wings originating 

 before the transverse median nervure. Prothorax very short. 



The affinities of this genus are with the Mellinini, but it has not 

 the appearance of a Mellinus or Gorytes. The very different neura- 

 tion separates it from the former ; from the latter the elbowed 1st 

 transverse cubital nervure, with its distinct nervule, the very much 

 longer clypeus, long tarsi and longer, narrower, lanceolate cellule, 

 should readily separate it. It has more the appearance of a Stizini 

 than of one of the Mellinini. 



TioiBj oprj minis longilarsis sp. dov. 



Black; the under side of antennal scape, face, clypeus to shortly below the 

 middle, a line on the pronotum, tubercles, a line along the sides of the meso- 

 notum, one on the post-scutellum, an interrupted line on the 1st abdominal seg- 

 ment and continuous broader ones on the others, yellow, these extending below 

 on to the 3rd and following segments. Tibise behind and more or less of the 

 basal joint of the tarsi in front, the 4 front tibiae at the base behind and the cal- 

 caria, yellow. Wings hyaline, the nervures black. % . Length 9 mm. 



Smooth, covered with a white down; the niesothorax sparsely punctured. 

 Hind ocelli separated from the eyes by a distinctly greater distance than they 

 are from each other. Third joint of antennae about one-third longer than the 

 fourth, shorter than the following two united. The 2nd ventral segment pro- 

 jects below the first. The hind legs, and especially the tarsi, are much longer 

 than the anterior.

% til liophilus hirticeps sp. nov. 



Black ; face, clypeus, inner orbits narrowly to the top of the eye incision, an 

 elongate large mark on the front, roundly narrowed and ending in a short point 

 above, narrowed below and united to the yellow on the face, two marks, broader 

 than long and obliquely narrowed on the outer side, on the sides shortly behind 

 the eyes, a short line behind them, a broad band on the hinder edge of the pro- 

 notum, 2 short, elongated oval spots close to the base of the mesonotum, scutel- 

 lums. tubercles, a large mark, roundly narrowed to a point on the top above, and 

 slightly oblique below, a broad baud on the base of the 1st abdominal segment, 

 an equally broad, but more irregular one, occupying the greater part of the 2nd 

 and narrower, trilobate bands on the apices of the following three, yellow. The 

 apices of the femora broadly (the hinder more narrowly than the anterior), the 

 tibia? and the tarsi yellow. Basal five joints of the flagelluni broadly yellow. 

 Wings hyaline, the costa and stigma fulvous. % . Length nearly 7 mm. 



Head and thorax thickly covered with longish, white pubescence; the latter 

 above sparsely, the mesopleurse more closely and strongly punctured. Front 

 punctured and closely, finely, longitudinally striated. A deep triangular depres- 

 sion (the narrowed end behind) on the base of the metanotum, its centre and the
