ANOCHETUS. 39 



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

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

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

 medially triangular, produced backwards in a point between the 

 antennal cariuae ; antennal carinse short, laminate, comparatively 

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

 large, but not confluent posteriorly as in OdontomacJius ; antennas 

 12-jointed, filiform ; head posteriorly emargiuate, 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 compressed 

 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. 



$ . Very similar to the , the ocelli small, the mesonotum 

 short with lateral posteriorly convergent carinse. Wings sub- 

 hyaline, with a radial and two complete cubital cells. 



cj . 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. 



Key to the Species.

into longitudinal striae. Length 4*5 -6 mm. A. rudis, p. 41. 



b'. Punctures on head and thorax more dis- 

 tinct, not running into longitudinal [p. 41. 

 striae. Smaller, length 3*5 mm A. punctiventris, 



b. Basal abdominal segment smooth or only 



very lightly punctured, shining, not opaque 

 at base.
