48 FAMILY I. — SCUTELLERID^. 



tributed and common in the Adirondack^ of New York, where 

 there were low marshy spots with carices intermixed with the 

 swamp grasses." Parshley (1923, 782) states that he has 

 taken it "in large numbers in late fall in the White Mountains 

 by sweeping Solidago." 



10 (15). Hom^mus bijugis Uhler, 1872, 393. 



Form of aeneifrons but averaging a little smaller. Color much as 

 there, the ground hue usually paler and head with a rather wide dull 

 yellow stripe each side; narrow reflexed margins of pronotum and con- 

 nexivum clear yellow; pronotum usually with four vague dusky stripes, 

 these continued obliquely backward onto scutellum, also with a blackish 

 spot in the depressions near front angles; scutellum of female with a 

 narrow sutural paler stripe, this gradually widened and faintly bordered 

 with fuscous on the declivity; male smaller with all these markings 

 much less distinct, the scutellum being darker with numerous broken 

 transverse fuscous lines as in aeneifrons; under surface and appendages 

 colored as in that species, the dark punctures in the paler females being 

 less evident. Head, pronotum and scutellum more finely and regularly 

 punctate than in aeneifrons; apex of osteolar canal less curved. Middle 

 lobe of sixth ventral longer, narrower and more rounded in front than 

 there. Length, 6.5 — 8 mm. ; width, 4.5 — 5 mm. 



Union Grove and Elizabeth, 111., July 7 — 13 {Hart). Ranges 

 from western Illinois and Minnesota to Utah, British Columbia 

 and California and south to New Mexico and Arizona. Occurs 

 usually in sandy regions and is said to be frequent in the arid 

 plains bordering the Rocky Mountains. Uhler (1877, 365) re- 

 ports it as "not uncommon in the city of Denver, particularly 

 on rank growing plants in damp situations." Stoner (1920, 18) 

 says that in western and northwestern Iowa it is abundant at 

 certain seasons, most of the specimens being taken from 

 prairie and blue-grass pastures along the edges of woods. The 

 nymphs were more common in June, the adults in August. 



11 (16). Hom^mus parvulus (Germar), 1839, 107. 



Size smaller and form more narrowly oval and convex than in the 

 two preceding. Dull grayish-yellow, marked above with numerous fus- 

 cous punctures, these in part aggregated to form four vague dark stripes 

 extending from front of pronotum backward over the scutellum, the 

 latter with a narrow pale sutural stripe, this abruptly widened and 

 bordered with fuscous at declivity, then narrowed with sides parallel to 

 the apex of scutellum; head bronzed, with a yellowish stripe each side. 

 Under surface dull yellow, with numerous fuscous punctures along the 

 sides; legs yellow with black dots; antennae and tip of beak piceous. 

 Head narrower in front and more finely punctate than in aeneifrons.
