THE CANADIAN ENTOMOLOGIST. 29 



Newportia Utahensis, new species. — Head longer than wide, its sides 

 converging a little posteriorly and more strongly anteriorly from the 

 middle ; marked with a median longitudinal furrow extending from the 

 anterior, slightly indented margin, posteriorly about one-fourth the length 

 of the plate, and with a second short median furrow just back of the 

 middle ; the paired furrows on the posterior portion of plate beginning 

 near the middle and first converging and then diverging to the posterior 

 margin, evenly curving ; finely punctate. 



Antennae with the usual seventeen articles, the first four of them 

 sparsely clothed with relatively long bristles, the other articles subdensely 

 clothed on their outer surfaces with short setae. 



. Presternal plate punctate, its anterior margin on each side sub- 

 straight, the margins of the two sides meeting in the middle at a slightly 

 re-entrant angle ; no median excavation. 



First dorsal plate with the transverse or cervical furrow evenly 

 curving, a little angulate at the middle ; a depression or pit at the angle 

 of the cervical furrow ; the paired furrows bifurcating, the inner branches 

 uniting at the angle in the cervical furrow, and forming thus the typical 

 W-shaped impression. 



The logitudinal furrows on the second dorsal plate conspicuously 

 diverging from the anterior to the posterior margin. 



The oblique, shallow lateral furrows are distinguishable from the third 

 plate posteriorly. 



The last dorsal plate with its posterior margin gently convexly rounded 

 and slightly indented at the middle ; without a median furrow. 



Ventral plates finely and subdensely punctate ; each with a distinct 

 and scarcely abbreviated and distinct, fine submarginal furrows. 



Last ventral plate with the sides sub-straight or a little convexly 

 rounded ; strongly narrowed posteriorly ; the posterior margin but slightly 

 incurved. 



Basal segments of the ambulatory legs spinulose ; the tibia armed at 

 distal end with a conspicuous ventral spine, as well as with a second 

 somewhat stouter spine dorsal or dorso-lateral in position; tarsal joint with 

 a ventral spine below the distal end. 



Pseudopleura of last segment with their posterior processes conical 

 in shape, apically subobtuse ; posterior margin above and laterally from 

 the processes with a close row of short spines, which also cover the basal 

 portion of the processes ; similar short spines occurring over the entire
