basal margin. Scutellar stria a little less than half as long as 

 the eljtral breadth, free at apex. First discal strongly inflexed 

 to base and almost joining the second at that point. Fifth and 

 sixth confluent not far from the apical fifth of the elytra. 

 Ocellate punctm-es outside of the eighth stria strong behind 

 the middle of the elytral length but not reaching the apex. 

 On the third stria, about one fifth from the base, is a strong 

 puncture, while between the second and third striae are two 

 others, one a little antemedian, the other only a short distance 

 from the apex. Interstitial areas flat or nearly so, extremely 

 minutely punctulate and alutaceous. Length of elytron, 5'00"'°'. 

 Yery closely related in size and arrangement of striae in the 

 scutellar region to P. interglacialis Scudd., from the Scar- 

 borough beds, but evidently differs in color and texture. The 

 closest resemblance that I can find among the modern species 

 seems to lie with the melanarius group of Platynus, but here 

 I do not find an exact duplication of tlie arrangement of the 

 dorsal punctures. In giving the specific name, I have in mind 

 my late frienxi and preceptor. Professor Samuel Calvin, who 

 did so much to advance our knowledge of the Pleistocene 

 formations in Iowa. 



Chl^nius plicatipen^nis new species. 



Represented by a considerable portion of one elytron, of full 

 width but with the base and apex broken off. Color black, 

 surface moderately shining, no signs of pubescence remaining. 

 The striae are pretty deep but irregular, being composed of 

 short, longitudinal, impressed dashes, much as in the recent G. 

 inter 7'ioptus. The intervals are alternating in height, as de- 

 scribed for the modern G. atternatus^ the punctures fairly 

 deep, strong, so generally confluent as to form transverse 

 irregular rugae, occasionally broken up into granules. Length 

 of fragment, 6'00"^™, greatest width, 3•00^^•^ 



Apparently this elytron represents the remains of a Chlaenius 

 allied to the modern G. interrwjptiis Horn, occurring in Ore- 

 gon, Manitoba and the Pocky Mountains of Colorado, and G. 

 alternatiis Horn, from the Saskatchewan district. It will be 

 noted that both of these recent forms are decidedly northern 

 types. 



Agabus savagei new species. 



The type shows the upper surface of the head and prothorax 

 with the two elytra detached and lying a few millimeters dis- 

 tant. All of these fragments are black, feebly shining. The 

 head is finely but distinctly alutaceous, with a few small, scat- 

 tered punctures, the lines forming the posterior and inner
