specimens in all — differ from Say's description of Banchus ^quatus in having the 

 second submarginal cell petiolate, quadrangular and not pentangular as in Say's 

 species. The Banchus sequatus Say may be an Exetastes as this is now under- 

 stood. In addition to the neuration, the maculation of the nervures and the 

 color are different from Banchus iequatus Say. The Douglas county specimen 

 differs from the Eastern form as follows : Head yellow, except a broad band ex- 

 tending from immediately in back of the ocelli to the posterior edge of the inser- 

 tion of the antennse, the dorsulum and upper edges of the propleura chocolate 

 brown. 



Paniscus geminatus Say. 



Douglas county, Kansas ; September. 

 Limnerium perdistinctus, n. sp. 



Superficially like perdistincta, congeneric with obscuripes, to which it seems 

 to be more nearly related than to any other species. 



Female. — Length, 4.5 mm. Head minutely roughened ; cheeks shining; face 

 dull, face below the antennas and lower half of cheeks with abundant silvery pu- 

 bescence which, when viewed in certain lights, obscures the tegument; remainder 

 of the head apparently bare, the pubescence inconspicuous ; internal margins of 

 the eyes nearly parallel; antennse twenty-nine jointed, scape distinctly longer 

 than the first joint of the flagellum, but not as long as the first joint together 

 with half the second. Thorax almost uniformly sculptured like the face, the 

 middle of the posterior half of the dorsulum more closely sculptured than the 

 rest ; metapleura almost appreciably, closely, minutely punctured ; parapsidal 

 grooves very faintly indicated on the anterior half of the dorsulum by 

 nearly parallel, very narrow, longitudinal, slight impressions; mesopleura ob- 

 liquely bisected by a shallow, sinuate, impressed line that is rugulose, a 

 short impressed line at right angles to the anterior margin of the mesopleura 

 on the lower portion of the sclerite near the mesosternum ; basal half of meta- 

 notum almost triangular, the apex blunt, areola pentagonal, the sides of 

 nearly equal length, confluent with the petiolarea, the raised line separating the 

 two only faintly and partly indicated ; petiolarea angled in the middle, or nearly, 

 somewhat longer than twice the greatest width ; areas of metanotum distinctly, 

 more coarsely, sculptured than the dorsulum, rugulose ; petiolarea almost rugose ; 

 wings clear, faintly yellowish brown, stigma pale brown, nervures dark brown, 

 areolet quadrangular, the sides subequal, petiolate, the petiole about as long as 

 the second abcissa of the cubitus, first abcissa of the radius about three-fourths 

 as long as the second abcissa of the radius, transverse median nervure received a 

 little beyond the basal nervure, the third abcissa of the discoidal nervure nearly 

 two-thirds the length of the recurrent nervure. Abdomen dullish ; basal half of 

 the petiole shining and carinate on the sides, the tegument elevated from the 

 spiracle of the petiole to the posterior margin of the segment, forming an indis- 

 tinct carina; ovipositor exserted for a length a little greater than the width of 

 the abdomen at apex. Abdomen rather abundantly but inconspicuously pubes- 

 cent, thorax more densely pubescent than the abdomen, the pubescence very 

 apparent only on the metathorax. Black ; anterior and middle coxce brownish ; 

 mandibles, except tips, tegulaj, base of wings, anterior and middle trochanters 

 and distal joint of posterior trochanters yellow; femora and middle tibiae rufous, 

 anterior tibiae yellowish, posterior tibiae brownish, dark brown at base and apex; 

 tarsi somewhat brownish, the apical joints and claws decidedly brown; abdomen 

 with the apical margins of the segments beyond the petiole, excepting the apical
