D. Sherman, Jr., who collected the specimens, of a small lot of 

 Heteroptera found on the shores of the Lake at Marquette, 

 Michigan, in July. The fresh water aquatic forms, ordinarily 

 abundant in bodies of still water, were but slightly represented, 

 there being only one Belostoma fluminea Say, one Arctocorisa 

 nitida, several Gerris rufoscutellatus, and one G. remigis. Of 

 the land forms, the most abundant were Thyreocoris unicolor, 

 represented by about twenty or more specimens, Sehirus cinc- 

 tus in about the same number, and to judge from the frag- 

 ments, over thirty Galeatus peckhami, another species known 

 only from the type, and some one or two other specimens in 

 collections, and therefore a most desirable form from every 

 point of view. The full list of the species is : 



Perilloides cxaptus Say, two. Urcmocoris ferus Say, one. 



Pentatoma persimilis Horvath, Corythuca pcrgandci Heid., one.

Eliminating duplications, there was a total of 66 species 

 found under these conditions, 22 in the lake and 49 on the 

 ocean beach, five being found in both situations, these being 

 Sehirus cinctus, Nysius ericae, Eremocoris ferus, Lygaeus kal- 

 mii and Gerris remigis. The seashore specimen, however, was 

 not a shipwrecked navigator, but a true flier, as noted. These 

 species tot^illed 3CX) specimens approximately, or over, as no 

 count was kept of the common forms. The families were rep- 

 resented as follows, in the order of the number of species, 

 which is nearly the order of their abundance :
