620 SUPERFAMILY MIROIDEjE. 



versely oblong, disk coarsely punctate, inner apical angles narrowly 

 rounded. Dorsal segments of abdomen each with four or five transverse 

 rows of close-set punctures, each puncture, as well as those of pronotum 

 and elytra, bearing a long inclined yellowish hair. Femora distinctly 

 swollen, their front side flattened and with a wide shallow groove. 

 Length, 3.6—4.5 mm. (Fig. 156). 



Yarmouth, Nova Scotia, July 29 ; taken from the nest of cliff 

 swallow (Davis). Ranges from Nova Scotia and New England 

 west to Iowa, Colorado and California. Not taken but probably 

 occurs in Indiana. Not recorded from the southern states. 

 Occurs in the nests of chimney swifts and swallows and prob- 

 ably of wide distribution throughout our territory. 



Superfamily MIROIDEiE Kirkaldy, 1906a, 369. 



Small species of variable, but usually oval, flattened form and 

 delicate texture having the antennae 4-jointed, longer than 

 head, the two apical joints usually more slender than the basal 

 ones ; pronotum always present ; scutellum usually distinct ; 

 elytra of macropterous forms (except in Cryptostemmatidse) 

 with five divisions, viz., clavus, corium, embolium, cuneus and 

 membrane, the embolium not always distinct, the veins of mem- 

 brane either free or forming one or two closed cells (fig. 1) ; 

 meso- and metasterna separated by a distinct suture ; front 

 legs never raptorial ; tarsal claws, except in some Miridae, with 

 out arolia; last two or more ventrals or genital segments of 

 female cleft along the middle and enclosing between them a 

 narrow grooved sheath for the ovipositor (pi. VIII, figs. 9 

 and 11). The superfamily, as thus characterized, comprises 

 six of our eastern families. 



KEY TO EASTERN' FAMILIES OF MIROIDE.F:. 



a. Ocelli present. 

 b. Tarsi 3-jointed. 

 c. Beak 3-jointed; joints 3 and 4 of antennae usually very slender, and 

 beset with numerous long spreading hairs (pi. VII, fig. 2). 

 d. Membrane in macropterous forms well defined and with one to 

 four free longitudinal veins, these often faint or obsolete; head 

 porrect; both macropterous and brachypterous forms known; 

 osteola present; length, 1.8 or more mm. Terrestrial or arbo- 

 real, often beneath bark; mainly predaceous. 



Family XXIV. ANTHOCORlD,E, T "a p. 621. 



dd. Membrane absent or very poorly defined ; disk of corium with one 



or two longitudinal veins reaching almost to apex (pi. VII, figs. 



70 a Since the pages treating of this family were in type, there has appeared a 

 paper by Drake & Harris (T92t!) in which seven new species from the eastern states 

 are described. These are not included in this work.
