secundi sulco quadrantali ; — niger pruinosus, antennis basi squamulis 

 pedibusque flavis: mas; — silaceus subdiaphanus, oculis ocellis thora- 

 cisque dorso medio fuscis : femina. 



Subgenus 2. Entomtus Herrich-Schaeffer. 



Palpi maxillares 5-articulati. Petiolus latior quam longior, vel sub- 

 aequidiameter. 



2. campanulatus Herrich-Schaeffer, — halidaji Forster : nigerisqua- 

 mulis pedibus antennarumque basi {maris subtus, femina undiique) 

 ferrugineis, scutello laevi, petiolo subquadrato. % 



3. rugulosus Forster : niger, femoribus tibiis tarsisque ferrugineis, 

 scutello apice emarginato abdomineque scabriculis, petiolo oblato : 

 femina. 



Genus 3. BELITA Jurine. 



Antennae in fronte porrecta insertae, ab epistomate distantes, scapo 

 frontis altitudinem superante ; maris 14-articulatae, articulo tertio ex- 

 ciso, rarissime subintegro; feminae 15-articulata3, rarissime 14-articu- 

 latae. Alae anticae areola radiali parva, rarius subobsoleta, et brachiali 

 unica. Mesonoti scutum bisulcum. 



Mandibular impares, intus unidentatse. Palpi maxillares 5-articulati, articulo tertio 

 dilatato, labiales 3-articulati. Labrum transversum, margine rotundatum. Scutellum 

 fovea basali, puncto laterali perforato vel fenestrato in pluribus. Metathorax cancella- 

 tus, apice truncatus aut emarginatus. Abdomen segmentis octo, ultimo excepto spira- 

 culiferis, at nonnullis saepe retractis in femina. Alae nonnunquam brevissimae vel fere 

 obsolete. 



Subgenus 1. Acoretus n. 

 Mandibular decussatae longiores falcata3. 

 Belyta rufopetiolata Nees, and half a dozen British species more. 



Subgenus 2. Cinetijs. 



Mandibular decussatae breviores cultratae. Abdominis segmenta 

 nonulla in feminis abscondita. 



Belyta petiolaris Nees, Cinetus gracilipes Curtis ; etc., about ten Bri- 

 tish species in all. 



Subgenus 3. Belita. 



Mandibular decussatae breviores cultratae. Abdominis segmenta octo, 

 omnia conspicua. 



Belyta bicolor Jurine ; B. sanguinolenta Nees ; B, breviventris H.- 

 Schaeffer ; and many more British species. Cinetus armatus Curtis, — 

 picipes SLR&jurinei Nees, — with the metathoracic scutellum elevated into 

 a spine, and the base of the second abdominal segment surrounded by a 

 beaded edge, may perhaps afford grounds for another subgenus to be 

 detached from this. B. heterocera, with 14-jointed antennae in the 

 female, and the radial vein perpendicular and contracted into a dot, 

 may possibly be considered as the type of yet another.
