brevibus adspersum. — Baridiformes : {Barytychius, Jekel) — Typus : 

 Tychius hordei, Brulle ( = squamosus, Scb.). 



B. (Typus UJ.) Articulo 1° funiculi antennaruni mediocri, 2-4° sub- 

 conicis successive brevioribus, ultimis rotundatis ; tborace subovato, 

 modice ampliato ; elytris ovatis medio latioribus : segmentis 2-4° abdo- 

 minis normalibus. Corpus oblongo-ovatum aut oblongum, squamis 

 elongatis setifomiibus inclinatis, in elytris seriatis, adspersum. — Styphli- 

 formes: (Stypldotychius, Jekel) — Typus: Tych. scabricollis, Rosenli. 

 ( = asperatas, Dej. Catal.). 



Obs. I. — The characters given by Mr. Thomson to each of his three 

 genera of Tycliiina apply only to a limited number of European 

 species. 



Obs. II. — According to the artificial system of Schonherr, Tychius 

 carinicollis, Lucas ( = Aubeonymus pulchelhis, Jacq. Duv.), from 

 Algeria, South Spain (Cadiz), and Sicily, by the longitudinal channel 

 of its prothorax beneath not extending further than the somewhat 

 distant anterior coxas, strictly belongs to the second subdivision of 

 the Cryptorliynchides, where it might be placed near Ocladius ; but 

 I cannot see that it has anything to do with Hypsomus, as M. Jacq. 

 Duval states ; it rather resembles Pachy tychius, with a tendency 

 towards some species of Acalles.
