96 CASEY 



last segment; basal joint of the hind tarsi long as usual in this group, 

 almost as long as the next three combined. Length (6^) 17.8 mm.; 



width 6.8 mm. Washington State torva n. subsp. 



B — Nearly as in torva but still more elongate, the elytra nearly twice as long 

 as wide, with the sides similarly gradually rounding and oblique in 

 posterior two-fifths but becoming nearly straight to very feebly 

 sinuate near the apices; head ( 9 ) as in gravid ula, having the anterior 

 margin throughout the width, sometimes broken into four spots, 

 pale; prothorax as in that form but with feebler indication of impres- 

 sion interrupting the sublateral smooth vittae; elytra sculptured as 

 in torva, the flatter intervals rather more punctate than in gravidula; 

 abdomen with the four lines of pale spots well developed ( 9 ) , with 

 numerous pale spots on the sterna and coxae and one on the under 

 side of the femora, the spots of the two inner abdominal lines larger 

 than those of the marginal Hnes. Length (9) 17. 3-19. 7 mm.; 

 width 6. 2-7.8 mm. Colorado (Boulder Co. ). . boulderensisn. subsp. 

 15 — Form nearly as in the preceding, the size much smaller, the coloration 

 and sculpture almost similar; head (d^) densely punctate, the callous 

 areas very small and inconspicuous, the occiput impressed along the 

 median line; front yellow in anterior half, except a sinus above each 

 antenna and generally two rounded discal points, the yellow area with 

 a short posteriad median prolongation, the spot near the upper part 

 of each eye distinct to wholly obsolete; eyes somewhat prominent; 

 prothorax with the sides at two-fifths from the base subangularly pro- 

 tuberant, the apical margin broadly bisinuate; sculpture and orna- 

 mentation as in gravidula, except that the impression near the outer 

 smooth vitta is wholly obsolete; elytra as in the preceding forms grad- 

 ually oblique at the sides posteriorly, sometimes feebly sinuate toward 

 the apices; under surface and sometimes the femora inferiorly spotted 

 with flavate as in the preceding; abdomen strongly punctate, narrowly 

 sulcate at base, generally with a pale spot at each side of the sulcus, the 

 other spots nearly obsolete ( c?), the single spot at the centre of the fourth 

 segment, forming the apex of the two inner series, generally visible, 

 the last segment with a biramose spot at each side, which is however 

 frequently wholly obsolete. Length (c^) 13. 5-16.7 mm.; vddth 5.0 



6.0 mm. Lake Superior (Duluth and Bayfield) flavopicta n. sp. 



Form notably narrower and relatively somewhat more convex, the pale 

 broken fasciae of the elytra larger, almost always longitudinally conflu- 

 ent near the suture; general coloration and sculpture similar; head 

 smaller, less densely punctate and not so evidently pubescent, similarly 

 ornamented; prothorax similar but less transverse, the sides less angu- 

 larly tumid and at basal third, thence to the base frequently with an 

 intermediate sinus; elytra somewhat more produced at tip, with the 

 sides toward the apices more evidently sinuate, the apical truncature 

 transverse as usual, finely bidenticulate; under surface nearly similar 

 but with less evident ashy hairs, the abdomen more sparsely and evi- 

 dently less strongly punctate as a rule. Length (c?) 13. 5-14. 2 mm.; 

 width 4.8-5.2 mm. Pennsylvania and New York to Michigan.
