ANOCIIETL'S. 39 



front of the head and not Literally at the anterior angles, elon- 

 gate, parallel, the apex bent suddenly at right angles, and with two 

 or three teeth ; elypeus very narrow, almost obsolete at the sides, 

 medially triangular, produced backwards in a point between the 

 antenual cariuse ; antennal carinse short, laminate, comparatively 

 wide apart, covering the base of the anteunsi ; antennal hollows 

 large, but not confluent posteriorly as in Odontomachus ; antennae 

 12-jointed, filiform ; head posteriorly emarginate, the posterior 

 lateral angles prominent, the sides straight down to the level of 

 the eyes, then convergent ; eyes of moderate size, prominent. 

 Thorax broad and convex in front, rounded and slightly cjmpressed 

 posteriorly ; the pronotum constricted into a neck anteriorly, the 

 metanotum more or less truncate posteriorly ; legs moderately 

 long, femora and tibiae cylindrical, claws simple. Pedicel one- 

 jointed, the node moderately thick, on a level with the metanotum, 

 unarmed * ; abdomen elongate oval, the constriction between the 

 basal two segments distinct. 



2 . Very similar to the ^ , the ocelli small, the mesonotum 

 short with lateral posteriorly convergent carinae. AVings sub- 

 hyaline, with a radial and two complete cubital cells. 



J . Mandibles rudimentary, not dentate ; antennae very long, 

 filiform, the scape short, shorter than the 2nd joint of the 

 flagellum, which latter is more than four times as long as the 

 1st joint ; ocelli and eyes very large. Thorax with the mesonotum 

 very convex, rising well above the depressed pronotum ; the 

 scutellum large, gibbous, very prominent, almost conical ; legs 

 slender ; wings as in the $ ; node of the pedicel more flat, but 

 more or less as in the ^ ; abdomen massive, the constriction 

 between the basal two segments fairly distinct.
