fulminans of Sowerby's Br. Mis. and Stenocorus quadrimaculatus above mentioned, have originally been imported into Britain in timber; but if such species prove capable of enduring this climate, they become to all intents and purposes natives: and it is impossible to say how many insects may originally have so become inhabitants. It is therefore the duty of our Faunists to enroll them as such; taking good care to notice the peculiarities of their times and places of appearance. DONACIA. Fab. Syst. Eleut. Zostera, thorace rufo, nigro, bimaculato, elytris fuscis rufo-striatis, apice bidentatis. Fab. Syst. Eleut. 2. 127. 3. Rhagium muticum. Fab. Ent. Syst. 2. 306. et Donacia appendiculata. Panz. Faun.

Elytra sublævia testacea Fab. 1. c. OBS. This species is very closely allied to H. dermestoides of Ent. Brit. which is the D. minutus of Fab. and Paykull. HYDROPHILUS. foveolatus, niger, thorace postice foveolato, elytris striâ unicâ impressâ. Habitat in aquis stagnantibus prope Londinum, DESCR. Statura et magnitudo H. bipustulati, Ent. Br. Nova species.

Elytra nigro-picea, lente subtilissime, confertissime punctulata, striâ unicâ fere ad suturam impressâ; pedes sordide ferruginei, ELOPHORUS. Fab. Syst. Eleut. marinus, fronte bipunctata, thorace æneo, transversim impresso, elytris punctato-striatis, pedibus pallidis. Payk. Faun. Suec. 247.7. Habitat ad littora salina prope Kingston upon Caput viridi æneum, nitidum, punctis duobus tes. Thorax supra viridi-æneus, fossulis duabus profundis tranversis arcuatis medio, foveolaque utrinque obsoleta laterali, elytra sub nigro-ænea, striis decem integris punctis minutis impressis. Subtus niger. Pedes pallidi, ferruginei. Payk. l. c. 1 OBS. This insect with E. elongatus Fab. (which is Hydrophilus Cicindeloides of Ent. Brit.) Hydr. longipalpis. H. impressus. H. lutosus, and perhaps, H. luridus of Ent. Brit. recede materially in appearance, from the other Elophori, and will probably hereafter form a new genus. Hydrophilus piceus likewise differs so greatly from H. scarabæoides (fuscipes Ent. Brit.) that we are not satisfied at their being in one genus. HYDRACHNE. Fab. Syst. Eleut. gibba, brunnea, sericeo nitens. Fab. Syst. Eleut. 1. 25. 6. 2. Habitat frequens æstate, in aquis stagnantibus prope Londinum.

As the two lastmentioned insects appear sufficiently distinct; and as the account of Dytiscus ovalis of Ent. Brit. probably belongs to both, but rather confusedly, their specific characters are here given from Fabricius's last work; in which, together with D. Hermanni, and an Indian species, called H. Scripta, they are formed into the genus Hydrachne; which indeed seems a natural and distinct one. DYTISCUS. Fab. Syst.
