sutural straight and approximate. Abdomen as wide as the elytra and much 

 shorter, nearly as in lacustris. Length 1.75-1.8 mm. ; width 0.75 mm. 



Canada (Ottawa — Mr, W. H. Harrington); Rhode Island 

 (Boston Neck). 



Allied rather closely to the preceding but distinguished from it 

 by the stouter and more Incrassate antennae, slightly shorter and 

 more convex elytra, especially in the female, with the humeral 

 swelling very much more pronounced and the sides consequently 

 much less divergent. As in lacustris the female differs in its 

 shorter and more incrassate antennae, smaller eyes, larger and more 

 transverse prothorax, nearly f as wide as the elytra, in its much 

 shorter el3'tra with more diverging sides, somewhat less promi- 

 nent humeri, and, as apparently usual in the genus, shorter discal 

 stria and relatively larger abdomen, this being fully as long as the 

 elytra from a perpendicular viewpoint. The last antennal joint 

 of the female is fully as long as the four preceding combined. 



As usual, the ventral segments of the male diminish but slightly 

 in length from base to apex, in marked contrast to the Bryaxini, 

 and the last is but little longer than the penultimate, with a small 

 rounded sinus at tip enclosing a minute horizontal pygidium. 



P. georgianiis. — Eather stout and convex, shining, subimpunctate, the 

 body, legs and antennae throughout rufo-testaceous, the abdomen blackish; 

 vestiture rather sparse, appressed, rather longer and less squaraiform than 

 usual, pale luteous-white and conspicuous. Head not distinctly narrower 

 than the prothorax, slightly wider than long, the eyes very large and promi- 

 nent, separated by scarcely three times their own width; frontal longitudinal 

 furrow long and distinct, the fovete normal, the apical the smallest of the 

 three. Antennse long and rather slender, fully as long as the head, prothorax 

 and elytra combined, the funicle only slightly incrassate distally, the last 

 joint fully as long as the three preceding, slightly swollen and obliquely 

 pointed toward tip and almost twice as wide as the tenth; fifth joint much 

 elongated, rather longer than the fourth, distinctly longer than the sixth 

 and only a little shorter than the third; tenth distinctly elongate and as 

 long as the ninth. Prothorax relatively rather small, }4 wider than long, 

 parallel, narrowed near the apex, the latter broad and transverse; median 

 fovea extending rather beyond the middle. Elytra large and well developed, 

 almost fully as long as wide, much longer than the head and prothorax and 

 rather more than twice as wide as the latter, the sides somewhat strongly 

 divergent and nearly straight from the moderately developed humeral swell- 

 ing, broadly arcuate in apical half, the apex somewhat narrower than the ante- 

 apical width; striae normal. Abdomen barely as wide as the elytra and much 

 shorter. Length 1.75 mm.; width 0.73 mm.
