Antennae short and moderately stout; inserted well before the eyes; 
eyes not emarginate; terminal segments of palpi short and clavate; front 
of head oblique; prosternum broadly excavated; pronotum with sides 
strongly tubereulate; hind wings without a closed cell in the anal region; 
elytra with longitudinal and transverse rugosities cribrate; tibial spurs

Pseudopachyta rugipennis Newm., 1844, The Zoologist, p. 476. 
Length 10 to 16 mm.; dark coppery brown, legs and antennae dusky 
reddish; pronotum wider than long in the female, nearly square in the 
male, base much wider than the apex, sides strongly tubereulate; elytra 
very strongly cribrate, the anastomosing ridges shining, with a narrow, 
pale yellow, obliquely transverse, irregular, median vitta on each elytron, 
directed caudad from the lateral margin to the suture, neither of which is 
quite attained. 
Twenty specimens are before us from Hull, Que.; Bathurst, N.B.;
