by Maklin (1881, p. 42) for dicksoni: the broader 5th and the narrower 9-ioth antennal 

 segments, shorter elytra, and more shining abdomen, are by no means constant. The S 

 genitalia seems to be almost identical, though the penis (median lobe) is slightly shorter, more 

 parallelsided and with blunter apex in Greenland specimens. The species (dicksoni) has also 

 been reported from the Pribilof Islands off Alaska (vide Leng, Suppl. I, 1927) and thus 

 apparently has a high-arctic circumpolar distribution. Mr. W. O. Steel, Maidenhead, 

 Berks., who is revising the genus, informs me that probably two or three subspecies are 

 involved, the population of the Pribilof Islands likewise deviating in some minor points. 

 6. Simplocaria. The Greenland species is apparently the North American tessellata Lee, 

 according to a series from Churchill, Man. (det W. J. Brown, Mus. Ottawa), and not identical 

 with the European metallica Sturm. The species are very closely related but in tessellata the 

 pilosity of elytra is a little denser, forming more contrasting dark and light spots. The 

 penis (median lobe) is slightly slenderer and a trifle more enlarged towards apex, the denticles 

 along the sides in front of the flattened apex are more pronounced; but these differences are 

 so slight that it is easily understood why Szekessy (1936, p. loi) could declare the genitalia 

 of Greenlandic and European c?o as identical. — Apparently two species (other than remota
