part behind finely transversely striated. First abdominal segment strongly and 

 closely punctured, the others almost impunctate. Third cubital cellule along the 

 radius distinctly longer than the 2nd ; the 1st recurrent nervure is received 

 shortly behind the middle of the cellule. Last ventral segment with a broad, 

 semicircular incision. Apical half of scutellum deeply furrowed in the middle. 

 Tarsal fringe long and white. Apex of clypeus broadly rounded ; the hair pencil 

 long, white. Abdominal segments hardly constricted at the sutures. 



Hab. — Mexico. 



Does not fit exactly into any of the genera of Dr. Ashniead's 

 Synopsis, but comes as near to Epiphilanthus as any. 



Antliopliilus melaiiaspis sp. nov. 



Black ; a large, somewhat triangular mark (the narrowed upper end is rounded, 

 the lower transverse) on the clypeus, a broadish line on the lower half of the 

 inner orbits, narrowest above, a mark on the lower part of the front, the top 

 broad, irregular, the lower and longer part narrower and rounded, 2 oblique 

 spots behind the ocelli, 2 short lines on the outer part of the orbits, behind the 

 top of the eyes, a line on the hind edge of the pronotum, tegulae, basal half of 

 2nd abdominal segment (the line of equal width) a narrow line on the apex of 

 the 3d, the apical half of the 4th and 5th, a mark on the sides of the 6th and 

 small marks on the sides of the 3rd to 5th segments, yellow. Tibise and base 

 of tarsi yellow in front. Wings hyaline, the stigma fulvous, the nervures darker 

 colored ; the 3d cubital cellule along the radius distinctly longer than the 2nd ; 

 the 1st recurrent nervure received almost in the middle of cellule; the 3d trans- 

 verse cubital nervure angled and emitting a short branch near the cubitus. 

 Antennal scape yellow ; the 2d joint of flagellum brownish below. £> . Length 

 8 mm. 



Hinder part of vertex strongly but not closely punctured, the rest of it and 

 the front closely rugosely punctured, the punctures intermixed with striae. 

 Mesonotum strongly, irregularly punctured, the apex closely rugose. Scutellum 

 smooth in the centre, the sides somewhat strongly punctured. Basal half of 

 postscutellum smooth, the apical weakly punctured. Median segment closely 

 strongly punctured ; a deep, crenulated furrow of equal width on the basal half; 

 the part surrounding the apex of this is raised and smooth. Propleurse weakly, 

 the mesopleurse strongly punctured ; the lower part of the former striated ; the 

 base of the metapleune closely obliquely striated, the rest closely punctured. 

 Abdominal segments strongly, deeply but not closely punctured, their base 

 smooth, pygidium smooth. 



Hab. — Mexico. 



intliopliiliis iiiu4'iiliv«-ii(riM sp. nov. 

 Black ; the clypeus, a large triangular mark above, the narrow top reaching 

 close to the eye incision, mandibles to shortly beyond the middle, a small trans- 

 verse line in the centre of the face, a transverse mark on the front, roundly nar- 

 rowed below, the sides obliquely dilated above, the top broadly, slightly de- 

 pressed, two large oblique marks behind the ocelli, a longish mark, transverse 

 behind, rounded before on the upper outer orbits, a line on the pronotum, tegu- 

 lse, two small marks below them, the anterior the smaller and rounder; postscu-
