THE CANADIAN ENTOMOLOGIST. 227 



loa. (iia) Vertex six times the synthlipsis ; width of pronotum one and 

 two-thirds times the length; width of scutelkim one and one- 

 quartertimes the length ; length of insect, 



8 to 8.8 ram . . Raleighi, n. sp. 



iia. (loa) Vertex six to eight times synthlipois, etc., etc. U/ileri, Kirkaldy. 

 This species is locally abundant at Raleigh, N. C, and I also have it 

 from Delair, N. J. (VV. P. Seal) ; Chicago, Ills. (V. E. Shelford); Running 

 Lake, Mississippi River Bottoms, Ills. (Prof. C. A. Hart) ; Bladensburg, 

 Md., and Washington, D. C. (O. Heidemann). The Washington and 

 Bladensburg specimens I had placed in JV. variabilis in my revision of 

 the genus cited above, taking them, as noted, for dwarf specimens of the 

 latter species, but a larger series showed unmistakably that it was a 

 different species. 



Family Naucorid.e, Genus Pelocoris, Stal. 



Pelocoris Caro/inensis, n. sp.. 



Head. — Broader, including eyes, than long ; front more or less 

 remotely punctuated and furrowed ; width at base and at widest part 

 subequal ; eyes longer than wide, greatest width about one-third from the 

 distal end ; sinuate in the inner margin, converging toward the distal end 

 more than toward the proximal end. Labrum broader at base than long ; 

 triangular in shape, with rounded apex attaining the middle of the third 

 segment of the rostrum. Rostrum short, stout. 



Proiioium about 2] i times as broad at base as long along the median 

 line; broader at base than at distal margin; both basal and distal margins 

 more or less sinuate ; edges curved regularly from the eyes to the humeral 

 angles, which are rounded ; disk with indented lines behind the head, 

 parallel to the anterior margin, the first line as long as the distance between 

 the eyes, and diminishing in length posteriorly, giving an obtusely 

 triangular shape to the lined area, the remainder of the disk coarsely 

 punctuated, caudad of the pronotal suture it is shagreened in wavy lines. 



ScuteUum about twice as broad as long along the medial liie; apex 

 blunt; sides sinuate, shagreened. 



Hemelytra narrower than abdomen, but extending to end of same. 

 Membrane distinct, but merging insensibly into the corium. Embolium 

 flattened and broadened marginally, extending beyond the abdomen. 

 The three last connexival segments have prominent posterior angles. 

 Entire hemelytra, including the membrane, covered with very short, sparse 

 golden hairs. Mesosternal keel slightly raised, grooved longitudinally 

 with hairs arising on either side, and nearly covering the groove. 



Abdomen. — Genital segments prominent in male, flattened and cleft 

 in female. These segments are somewhat complicated, and no adequate 

 description can be made without a dissection.
