of the twenty-seven beach-drift species, namely, Chlorochroa 

 uhleri and Lopidea caesar, were found commonly on the dunes 

 proper, the others occurring for the most part in the inland 

 regions. 



List of Species 

 Scutelleridae: 



Eurygaster alternatus (Say). Moderately common in 

 marshy localities, where it occurs among the grasses and 

 sedges. Specimens were taken at New Buffalo (June 30), 

 near the Sawyer Dunes (July 21), and at the Grand Marais 

 (July 22). 



Cydnidae 



No species of the subfamily Cydninae were taken, though 

 doubtless some occur here. Members of the Corimelaeninse^ 

 were taken only occasionally. 



Galgitpha atra A. & S. One specimen was swept from a 

 tangle of grasses and vines on the flood plain of the Galien 

 River, in the Warren Woods, September 7 (T. H. Hubbell). 



Galgupha aterrima Malloch. One was swept from ground 

 vegetation on the dunes near Harbert, June 22. 



Galgupha nitiduloides (Wolff). One was taken from road- 

 side grasses near Three Oaks, June 21, and another was beaten 

 from vegetation in a clearing behind the Sawyer Dunes, 

 July 26. 



Corimel<rna pulicaria (Germ.). Several specimens were 

 taken from ragweed (Ambrosia) and a few were found in 

 marsh grasses near the Warren Woods, July 5-6 ; several were 

 collected from roadside grasses near Bridgman, July 20. 



^ If Thyreocoris and Corimelsena are to be regarded as distinct 

 genera, the name of this subfamily reverts from Thyreocorinae (Van 

 D. 1907) to Corimelaeninae (Uhl. 1872). This point was overlooked 

 by Malloch {Bull. III. Nat. Hist Surv., xiii, p. 206, 1919).
