In a region where there are so manypools and ponds and so much water, we findthat water-beetles are very common belong mostly to the family Dytis-cidse, and are, like the ground-beetles, car-nivorous, feeding on tadpoles, aquatic insects,and small fish. My desire to obtain two particular members ofthis family was what first interested me in Labrador insects. One of these beetles {Agahus ardicus Payk) is shown in Figure Fig. arcticus. 444 Appendix i It was first described from Lapland, and is very common in Lab-rador, but occurs nowhere else in America. It is a narrow, slenderinsect one-quarter of an inch long, yellowish brown, with the headand a band across the thorax (or middle portion of the body)black. The wing cases are quite rough and uneven. The other beetle which Isought in the beginning frommy Labrador friends {Agahusinfuscatus Aube) is appar-ently even more commonthere than the one in theillustration. It has been re-corded from Mount Wash-ington and Lake Superior,but it is certainly not com-mon at either of these is shorter and more robustthan Agahus arcticus; thewing covers are brown, thehead and thorax black. The large water-beetleshown in the next figure ( Dytiscus dauricus Gebl)is one of the largest of theLabrador beetles, being aninch and a quarter long. Itis greenish black, with the
