THE CANADIAN ENTOMOLOGIST. 115 



black band covering its basal field and the base of the elytra. Elytra 

 yellowish green, nervures concolorous ; apical areoles, a large costal cloud 

 beyond the middle sometimes extended along the centre of the antiapical 

 areoles, a line adjoining the claval suture, and the commissural nervure, 

 blackish fuscous. Wings wliite, nervures slender, brown. Legs and all 

 beneath black; rostrum, tips of the anterior and intermediate coxee, 

 knees, tarsi, spines of the posterior tibiae and the narrow edge of the 

 ventral segments, pale ; tergum black with a row of marginal pale spots ; 

 last ventral segment yellow, its sides and a heavy, double median line, 

 not reaching its apex, black. 



Genital characters. Female : Last ventral segment about the length 

 of the preceding ; hind edge feebly angularly concave and impressed 

 toward the middle. Pygofers a little swollen at their middle ; black with 

 a broad yellow dorsal line. Oviduct far surpassing the pygofers, rufous. 



Described from two female examples, one from Mississippi, kindly 

 given me by Mr. Howard Evarts Weed, and a smaller specimen taken 

 near Emporia, Kansas, by my brother Mr. M. C. Van Duzee. 



In the pattern of its markings this species recalls the dark coloured 

 specimens of Deltocephalus debiiis, Uhler, but may at once be distin- 

 guished by the banded head and pronotum and the more obtuse anterior 

 edge of the vertex. 



Athysamcs obtusus, n. sp. 



Form of the preceding. Head well produced, tumid, as wide as the 

 pronotum, apex obtuse, vertex pentagonal ; soiled yellow or fulvous, with 

 two large square black spots anterior to the middle encircled by paler. 

 Front with a few short arcs and a large squarish basal spot black ; above 

 this on the edge of the vertex is a concentric black band, interrupted in 

 the middle by a square pale spot at the tip of the head ; a large spot 

 below the antennae and sometimes the ocelli black ; outer margins and 

 apex of the face dusky or black. Eyes dark brown, edged with pale 

 behind. Pronotum well arcuated before ; surface strongly transversely 

 wrinkled, omitting the posterior and broad anterior margins, the latter

 pale, an angular black spot within the basal angles and a itw brown lines 

 on the middle. Beneath deep blue-black with one or two spots on the 

 pleural pieces and sometimes the narrow edge of the ventral segments
