note. It belongs to the same ovate section of the genus as the 

 two preceding species, from which its minute size and shining 

 impnnctate surface readily distinguish it. 



Aciidiinn Sharjt/anwii. (fist. Ent. iii, p. 31). PI. II, f. 2); this 

 remarkable species was lately found in the Sandwich Islands, by 

 the Kev. T. Blackbui'n, on the margin of a stream near Honolulu. 

 In form and colour it resembles the four preceding species more 

 than any of the rest, and may be known by its narrow elongate 

 form, and abruptly truncate apex of the elytra. 



Actiilinia concolor, (Trichop. lUustr. p. 81)), was first found 

 by Dr. Sharp and Mr. Crotch, on the margin of a stream in 

 Northumberland, and subsequently in a similar locality near 

 Dumfries, by Dr. Sharp ; a single example taken in Italy has 

 also been sent to me by H. E. v. Bruck. A. concidur forms a link 

 between the two sections of this genus, i.e., those whose surface 

 is sliinino' and more or less (Jjlabrous, and those which are clothed 

 with {(ubescence ; from the former it differs in its linear cyliu- 

 dric form, and from the latter in its shining and naked surface. 



Actulinin FoicIerianiuiK n. sp. Several specimens ol: this very 

 small species have been sent by Mr. Champion, from (Guatemala, 

 and as they are in the hands of Messrs. Godman and Salviu, I 

 will only say that they differ from all the other species in their 

 minute size (•37— '50 inm.), attenuated elytra, and silver-grey 

 colour. 



Avtuliiiiii lineure, (Cist. Knt. i, p. 2'J()). This species found 

 in some numbers by Mr. Dawson, in New Zealand, may 

 lie known bv its elongate linear form, longer pubescence, and 

 brown coloui'. It reseml)les A. ctmrctataiu, more than any of 

 the rest, but differs from that species in its more truly linear 

 form, and especially in the sculpture of the head and thorax. 



ActidiuiH coai-ctutiiin. (Trichop. Illnstr. p. 81)), appears to be 

 distributed thi'oughout the whole of Europe and the African 

 shore of the ^Mediterranean sea. I have received specimens 

 from various parts of England, and also from Ireland, Sweden, 

 Italy, the South of France, and Egypt. Its linear form, long 

 pubescence, and deeply punctured head and thorax, readily 

 distinguish ^1. ccaixtainia from its congeners.
