688 FAMILY XXIX. — MIRID^E. 



1 one-fifth longer than width of vertex; 2 slightly tapering from base to 

 apex, thickly clothed with short black hairs, three times as long as 1; 

 3 and 4 fuscous, 3 three-fifths the length of 2, nearly twice as long as 4. 

 Pronotum with basal margins of calli impressed, disk strongly convex, 

 both it and elytra finely granulate, finely and densely pubescent. Length, 

 7.5 — 7.7 mm. 



St. Anthony Park, Minn., June 2 (Minn. Univ. Coll.). De- 

 scribed from Minnesota, the two color varieties also from there 

 and from Maine. Adults and nymphs of the typical form were 

 taken on the figwort, Schrophularia leporella Bicknell. 



670 (909). Platytylellus insignis (Say), 1832, 22; I, 342. 



Velvety-black, opaque, finely granulate; head except tylus, pronotum 

 except part of the hind lobe and scutellum except the side margins or 

 basal angles, red; ventrals black, the basal ones tinged with red. Joint 

 1 of antennae but one-tenth longer than width of vertex, 2 nearly three 

 times the length of 1, 3 about two-thirds the length of 2, one-half longer 

 than 4. Beak reaching hind coxae. Length, 6.7—7.5 mm. 



Dunedin, Fla., April 10 (W.S.B.). Fairfax Co., Va., and 

 Beltsville, Md., June 22 — July 1 {Davis). Ranges from Ontario 

 and New England west to Iowa and North Dakota and south- 

 west to Florida and Texas. Recorded from many stations but 

 part of the records doubtless should be referred to rubrovittatus 

 and intercidendus, which it closely resembles in size and color. 

 In Florida it is much less common than rubrovittatus. 



670a ( — ). Platytylellus insignis fraterculus Knight, 1923, 554. 



Differs from the typical form in having the scutellum black and 

 ventral surface usually wholly red ; hind lobe of pronotum black with its 

 side margins narrowly pale, as is also often the case in typical insignis. 

 Length, 5.1 — 6.6 mm. 



Crawford and Posey counties, Ind., June 26 — July 7. Laurel 

 Hill, N. Car., June 22 (Brimley). Ranges from southern Indi- 

 ana north to Minnesota. The North Carolina specimens have 

 the ventrals wholly black, thus forming a connecting link be- 

 tween the typical form and Knight's variety. 



671 ( — ). Platytylellus borealis Knight, 1923, 553. 



Dull black; base of vertex, collar and a lateral stripe on flanks of 

 pronotum, red; ventrals 1 — 4 orange-red. Joint 1 of antennae as long as 

 width of vertex, male, slightly longer, female; 2 two and three-fourths 

 times the length of 1, 3 two-thirds as long as 2, 4 three-fourths the length 

 of 3. Beak reaching between hind coxae. Length, 6.3 mm. 



Morrison Co., Minn., July 10 (Minn. Univ. Coll.). A species 

 of northern distribution ranging from Ontario and New Eng-
