CiMICIDAE 



Cimex leqtularius Linn. I took one individual of this spe- 

 cies in a shack on the shore of Lake Michigan, near Bridgrnan, 

 July 22 ; and I have seen a second specimen from Berrien 

 County, taken at St. Joseph in August, 1918 (C. Blashill). 



Anthocoridae 



Xylocoris Fcursitans (Fall.). Common under the bark of 

 dead trees in the Warren Woods, particularly on fallen beeches. 



Anthocoris sp. One individual came to light near the War- 

 ren Woods, June 30. 



Triphleps insidiosus (Say). Abundant on dog-fennel and 

 other Compositse about the edges of the Warren Woods, and 

 also taken in the dune region. The dark variety tristicolor 

 was rarely taken. 



MiRIDAB 



Collaria meilleuri Prov. Moderately common in the grasses 

 in moist situations, both at the Warren Woods and in the 

 dune region, June 23 to July 20 ; one specimen was taken from 

 the margin of a cranberry bog near Livingston, July 22. 



Collaria ocnlata (Reut.). This species was taken only in 

 the dune region, where it was about as common as C. meilleuri. 



Miris dolobratus (Linn.). Abundant everywhere in grassy 

 situations during June and early July. 



Stenodema tncinmn (Prov.). A very common grass bug in 

 all of the localities studied, occurring most abundantly in 

 marshy places. 



Trigonoiylus ruHcornis (Fall.). Another very common 

 grass-dwelling Mirid in all my collecting localities, but, unlike 

 the last, this form was found most commonly in dry fields and 

 pastures, and in sandy uplands where the grasses were rather 

 scanty.
