[The following nine North American species are very closely allied, 

 and have a similar design, though modified in each form or species; 

 the punctuation also appears to vary; typically the elytra have each 

 sis spots arranged in two triangles, the basal one with the apex on 

 the callus, the other reversed subapical ; the thorax is margined with 

 white in front and on the sides and there are two converging white 

 marks on the disc] 



H. 5-signata, (Kirby) Faun. Bor. Am., p. 230,512, pi. 7, f. 7; Muls. Spec., 

 p. 15, 5; extensa, Muls. Spec, p. 17, 6; Malsanti, Lee. Proo. Phil, vi., 131, 2; 

 leporina, Muls. Op. vii., 135. — Punctuation clear, distinct, close, head with a 

 white medial spot on the front, thorax with the anterior angles triangularly 

 white; external spot of the basal triangle absent, the other two forming a com- 

 mon concave fascia, the two upper spots of the apical triangle also connected 

 together. L. -25— -27 inch. 



Hudson's Bay, Lake Superior, New York, Kansas. 



The white spot at the anterior angles of the thorax is carried more 

 or less backwards to the posterior angles and the spots on the disc are 

 exceptionally visible ; the apical triangle has all three spots discon- 

 nected, or the apical one absent, the basal fascia is very rarely broken 

 up into two spots. 



H. aiubigua, Lee. Proc. Phil, vi., 131, 3; punctulata, Lee. I, c, 131, 4. 



Similar to H. b-signata by its head and thorax, the frontal spot 

 shows some tendency to be prolonged to the eyes, the discal marks are 

 more often present on the thorax, the elytra are alutaceous and obso- 

 letely punctate, generally spotless, or with the spots very small, and 

 distinct as in convergens. 



California, Oregon. 



H. Leeontei, Muls. Spec, p. 1010. — About the size and form of H. glacialis 

 from which it differs by the distinct punctuation, which is nearly as clear as in 

 H. b-signata. The anterior spots are entirely absent (or all three present but 

 small), the posterior pair generally united, the apical one sometimes absent; 

 thorax with the lateral border sinuate, the anterior angles triangularly white, 

 a median triangle on the anterior margin, and two obsolete discal spots. L- 

 •28— -30 inch.
