Aleodorns Say. " Head prominent, with a distinct neck, not in- 

 serted into the thorax ; antennae inserted into the anterior internal 

 orbit of the eye; three basal joints longest; maxillary palpi long, 

 terminal joint acicular; thorax longitudinal, rounded on the sides, or 

 without lateral edge; feet simple" (Say). While Say's above diag- 

 nosis is very unsatisfactory, the type of the genus, bilobafus Say, 

 is sufficiently well described to be recognizable, and is accepted on 

 our lists. The principal characters of Aleodorus are : the simple man- 

 dibles and the structure of the mesosternum, " its hind margin being 

 on a rather different level to the pieces behind it, and thus appearing 

 free, while in the middle it is not produced backwards between the 

 coxae, but forms only a very obtuse angle" (Sharp). The scutellum 

 is channelled longitudinally (as a rule), but the channel is sometimes 

 imperfect, or even obsolete, apparently in specimens of the same 

 species, the labrum is subtruncate, the mentum sinuate, the ligula 

 bifid to about one third, the maxillary palpi with joint 2 short, joint 

 3 feebly securiform, the prosternum behind the front coxae with a 

 large corneous plate on each side, the plates contiguous in the middle, 

 the mesosternal process obtusely angulate at tip. 



Chitalia Shp. has to go in synonymy, if Aleodorns Say is accepted, 

 the latter being the older name. The type of Chifalia is: crenata Shp. 



Drepanopora Brnhr., with type borboroporoidcs Brnhr., appears 

 to be an aberrant genus, on account of the approximated middle 

 coxae; other generic characters are said to be the dentate mandibles 

 and the pointed mesosternal process. 



Eccoptoglossa Luze, another monotypic genus, with obsciira Luze 

 as type, has both mandibles dentate, the right one acutely, the left 

 one obtusely ; the ligula is bilobed and the middle coxae are separated. 

 The genus is unknown to me. 



Beyond question is the validity of the genus Falagriota Csy., with 

 occidua Csy. as type. The narrow, transverse corneous plates of the 

 prosternum, separated from one another in the middle line, are suffi- 

 cient to separate this genus from its allies in the Falagna group. 

 Additional characters are : the robust tooth in the middle of the 

 inner margin of the right mandible, the simple left mandible, the 

 (at tip) bifid ligula, and the rounded mesosternal process; the scu- 

 tellum is simple.
