296 FAMILY IX. — ARADID^E. 



Quebec and New England west to Indiana, Van Duzee's Cali- 

 fornia records (1917, 130) being based upon his a picalis, a 

 western species since described. Resembles ornatus closely but 

 lacks the polished spots on base of pronotum. Other differences 

 between the two are pointed out by Bergroth (1892, 334) as 

 follows : "In ornatus the head is shorter, second joint of an- 

 tennae more incrassated toward apex ; thorax shorter, more 

 transverse with greatest breadth at middle ; scutellum shorter, 

 more widened at base, the apex entirely black; basal part of 

 corium more dilated; genital lobes with basal half (not inner 

 half as in duzeei) yellow." 



221 ( — ). Aradus implanus Parshley, 1921, 45. 



Elongate-oblong. Pale brown, head and pronotum somewhat darker, 

 the latter with a yellowish area behind each apical angle, corium and 

 membrane fuscous toward tips; connexivals fuscous, the apical third of 

 each paler; legs pale brown, femora vaguely annulate with yellow near 

 base and apex; under surface brownish-yellow, finely and densely gran- 

 ulate. Head as broad across eyes as long; tylus and antenniferous 

 spines stout, obtuse, the former with sides flattened. Antennae as in 

 fig. 14c, stout, covered with flattened scales, joint 1 scarcely reaching 

 middle of tylus, 2 slightly clavate, almost as long as width of head 

 across eyes, 3 as thick as and one-half the length of 2, 4 fusiform, two- 

 thirds as long as 3. Beak reaching tips of front coxa?. Pronotum 

 widest at middle, sides broadly obtusely rounded, strongly reflexed, their 

 margins granulate; disk with two median carina? percurrent, four lateral 

 ones abbreviated. Scutellum slightly longer than pronotum with sides 

 elevated, densely granulate. Basal expansions of corium rather large, 

 reflexed, with edges granulate. Genital segments of male and female 

 as in fig. 14, b and a. Length, 5.8 — 6.3 mm. (PL I, fig. 14). 



Funk's Grove, 111., April 30 (III. Nat. Hist. Surv. Coll.) . Re- 

 corded from Indiana by Parshley ; also from Ontario, Pennsyl- 

 vania and Michigan. 



222 (368). Aradus curticollis Bergroth, 1913, 2. 



Broadly-oval. Black, finely granulated ; membrane brown ; front 

 and middle tibioe paler at middle. Head as long as broad, much longer 

 than pronotum; tylus short, broad, slightly widened apically; anten- 

 niferous spines slender, slightly divergent; eyes very prominent. Beak 

 reaching between front coxae. Antennae rather slender, as long as head 

 and pronotum united, joint 1 reaching apical third of tylus, 2 sub- 

 clavate, almost as long as width of head across eyes, 3 and 4 subequal, 

 united two-thirds the length of 2. Pronotum rather flat, nearly three 

 times wider than long, sides broadly rounded, their margins entire; 

 carinae moderately elevated, median pair percurrent, the outer ones very 

 short. Scutellum nearly one-third longer than pronotum, sides feebly 

 elevated, basal half of disk with obtuse median elevation. Elytra di-
