York, Pennsylvania, Michigan and Illinois. This is the form 

 identified as burmeisteri by Bueno and others, but the original 

 description of that species is so brief and unsatisfactory that 

 a comparison with the type is necessary to prove the identity 

 of the two forms. It is closely allied to concinnus but that spe- 

 cies is easily distinguished by its longer, more slender, wholly 

 pale antennae and entire tip of scutellum. 



II. Merragata White, 1877, 113. 



This genus differs from Naogeus mainly in the characters 

 given in generic key. A half dozen species are known, three 

 from Central and South America, the others from our territory. 



KEY TO EASTERN SPECIES OF MERRAGATA. 



a. Apex of scutellum blunt, not bifid; joints 1, 2 and 3 of antenna? sub- 

 equal in length. 

 b. General color blackish or dark chestnut-brown, the membrane with 

 distinct fuscous spots; sides of pronotum moderately constricted, 

 the disk with a broad, deep, longitudinal furrow. 586. hebroides. 

 bb. Color pale chestnut-brown, the membrane milky-white; sides of 

 pronotum more strongly and abruptly constricted, the disk with 

 a more narrow, ill defined median groove. 587. brunnea. 



act. Apex of scutellum obtusely bifid; joint 3 of antenna? shorter than 

 the others. 588. SLOSSONI. 



586 (813 x ,4). Merragata hebroides White, 1877, 113. 



Oblong, robust. General color fuscous-black; vertex, base of tylus 

 and two round convexities on hind portion of pronotum, reddish-brown; 

 antenna? reddish-bi'own, the fourth joint fuscous; beak and legs brown- 

 ish-yellow; elytra with white spots on clavus, corium and membrane 

 much as in Nseogens consolidits; under surface thickly clothed with fine 

 grayish pubescence. Head as wide across eyes as long, its front portion 

 declivent; eyes small, prominent, coarsely granulated; antenna? short, 

 about one-half longer than head, joints 1 — 3 subequal, 4 longer and 

 stouter, fusiform. Pronotum with disk uneven, the median groove ex- 

 tending from apex to basal third, front portion with several fovea? beset 

 with small punctures, hind portion gibbous each side of end of median 

 groove; humeral angles convex, rounded. Scutellum with a fine median 

 carina. Elytra reaching tip of abdomen, inner nervure of corium angu- 

 late at apical fourth; connexivum narrowly exposed. Length 1.6 — 2 mm. 



Clark Junction, Ind., Aug. 7; Chicago, 111., June 3 — July 22 

 (Gerhard). Ranges from New York west to Colorado and Cali- 

 fornia and south to Florida. Described from Hawaii and again 

 by Champion (1898, 122) from Mexico. I regard the M. 

 foveata Drake (1917, 103) as a synonym of hebroides. The only 

 character given by Drake in his key to separate them is that
