of the radius a little more than two-thirds the length of the second abcissa, 

 areolet petiolate, quadrangular, almost a perfect square, petiole shorter than any 

 side of the areolet, transverse median nervure interstitial, the second abcissa of 

 the discoidal nervure almost two-thirds the length of the recurrent nervure. 

 Abdomen as in perrivalia. Pubescence as in perrivalis. Black; mandibles yel- 

 low, brown at tip; tegulte, base of wings and trochanters yellow; proximal tro- 

 chanters of posterior legs largely black, yellow only at apex, four anterior legs, 

 coxaj included, brownish testaceous, apical tarsi and claws brown or brownish, 

 posterior femora rufous, posterior tibi;i.' above with a broad brown band at base 

 and apex, brownish yellow between, beneath somewhat rufous, the tarsi and

Amorphota psenexareolata, n. sp. 



Superficially like tibiator, which is more distinctly areolated. 



Male. — Length, 5 mm. Head sculptured very much as in the preceding 

 species; antennte thirty one jointed. Thorax largely dull or dullish; dorsulum 

 with broad, faintly impressed parapsidal grooves, very closely rugulose, the sur- 

 face between the parapsidal grooves closely sculptured, dull, the surface between 

 the parapsidal grooves and the sides of the dorsulum more shining and rather 

 distinctly, closely punctured; scutellum rather shining, closely, distinctly punc- 

 tured ; mesopleura largely shining and closely punctured, the depressed area of 

 the superior half of the posterior half of the segment smooth and shining to a 

 great extent, the smooth, shining area bounded by rugulose areas, a slight shelf 

 at its lower posterior margin ; basal area of metanotum nearly quadrate, the 

 areola if complete would form an irregular circle, petiolarea about twice as long 

 as greatest width, angled above the middle, not much wider than the areola; 

 metapleura rather shining, very closely punctured; wings almost clear, stigma 

 testaceous, nervures almost blackish testaceous; first abcissa of the radius a 

 little more than two- thirds the length of the second abcissa, areolet petiolate, 

 quadrangular, the petiole nearly as long as the longest side of the areolet, first 

 transverse cubitus a little shorter than the second, the two lower sides of the 

 areolet almost equal, second abcissa of the discoidal nervure about half the 

 length of the recurrent nervure, transverse median nervure received a little be- 

 yond the basal nervure. Abdomen as in perrivalis. The pubesence also as in 

 that species. Black; basal joint of the scape with a triangular yellow area; 

 mandibles yellow, brown at apex; tegula^ base of wings and trochanters as in 

 nocturna; anterior and middle coxa? largely yellowish, posterior coxse black, four 

 anterior legs otherwise testaceous, the apical tarsal joint and claws brown or 

 brownish, posterior legs rufous, tibire brownish above, tarsi brown, claws dark 

 brown.

Campoplex expertus Cresson. 



Douglas county, Kansas, 900 feet; F. H. Snow. 

 Campoplex photomorphus, n. sp. 



Related to C. bellus, in which the pubescence of the metanotum is sparser and 

 the median groove deeper. 



Female. — Length, 12 mm. Head very closely sculptured; cheeks rather 

 shining with shallow, almost adjoining punctures; face dull, with shallow ad- 

 joining punctures giving a reticulate or rugulose appearance; antennse over
