(6) Species found in water. These are very few in these islands ; 

 why, it is difficult to say ; hut with the exception of one AgaLus, 

 which may he uew, all are the most ordinary European forms. The 

 three new to the Atlantic fauna are prohably introduced. 



Hydroporus planus. Philhydrus lividus. 



Colymbetes jjulvei'osits. 



(7) Species introduced with garden plants, &c., about cultivated 

 ground. 



Melanotus dich'ousi Sitones ^avescens. 



Athous ohsoletusi lineatus. 



Ceiithorhyuchus nigrotcrmi- — — gressorius. 



natus. Bruchus pisi. 

 Hypera variabilis. Psylliodes chrysocephala. 

 Otiorhynchus scabrosus. Haltica ainpelophaga. 

 sulcatus. 



(8) Of the eighty-six European species remaining, the following 

 fourteen are probably mere recent introductions : — 



Calathus mollis. Sapriuus semistriatus. 



Bradycellus distvictus. Ptilinus pectinicornis. 



Phalacrus coruscus. Tomicus saxeseni. 



consimilis. Hypoborus fciis. 



Nitidula obsoleta. Coccinella 7-punctata. 



Anthrenus varius. Chilocorus bipustulatus. 



Saprinus ccerulescens. Scymnus minimus. 



(9) Sixteen species remain, now brought forward as new to the 

 Atlantic fauna, concerning whose origin I am not able to offer any 

 conjecture : — 



Licinus brevicoUis. Meligethes incanus. 



Anchomenus j)orum j)unctatus. Psammodius jjUcicol/is. 



Pterostichus vernalis. Dolichosomus )iobilis. 



Harpalus riijiconiis. Mesites tin-dii. 



griseus. Coccinella W-piinctata, 



Stenolophus brunnipes. Lithocharis ripicola. 



luridus. apicalis. 



Cory ihoXoYihvL^sublcevipennis. Trogophloeus subtilis. 



(10) M. Drouet enumerates a few species which have escaped Mr. 

 Godman, but which he appears to have found in some numbers : — 



G?i\vii\\ViS flavipes. Anobium tomentosum. 



Saprinus 7-iigifrons. Xantholinus ylabratus. 



Coccinella variabilis. 



(11) We then get the following thirty-tv.o as being found in the 

 three Atlantic groups and South Europe, and representing perhaps 

 the remains of a common fauna : — 



Dromius maurus. Anchomenus albipes. 

 Pristonychus complanatus. marginatus.
