FamilyLamiide.Echthistatus gibber, n. sp.E. spinoso, Pascoe (Journ.Ent.pl. 17. f. 8), forma similis.Brevis, fuscus, tomento vel squamis fulvo-terreis dense vestitus ; capite grosse, sparsim punctato; thorace subquadrato, medio paulo dilatato ibique utrinque spina elongata valida armato, supra multituberoso ; elytris ad trientem apicalem utrinque fortiter gibbosis, inter gibber et humerum flexuoso-carinatis, apice utrinque productis, mucronatis, supra passim inzequaliter granulatis ; antennis é corpore plusquam duplo longioribus, scapo scabroso, articulo secundo apice incrassato.Long.6-8 lin.¢ Q. Maiyasan and Kawatchi, in September.I place this extraordinary Longicorn, without hesitation, in the genus Eehthistatus, although it differs in armature from the type species (. spinosus), and inhabits a far distant country, if the locality '' Mexico' for E. spinosus be a correct one.In the form of the head (broad front, distant antenn, and concave vertex), antenne, legs, and general figure of the body, there is great similarity between the present insect and Pascoe's figure.
