366 MEMOIRS ON THE COLEOPTERA 



strongly punctate and glabrous; prothorax larger than in obliteratus 

 and more tubulate at base, as wide as the elytra or very nearly, the 

 apical and basal margins finely yellow, the apical band angularly 

 emarginate and almost divided at the middle; sculpture very fine 

 and densely punctato-rugulose throughout; elytra slightly more 

 than twice as long as wide, the posterior half of the scutellum and 

 adjoining lateral small spot, a broad oblique discal spot behind the 

 base, a broad sinuate fascia as before described near basal two-fifths, 

 a feebly oblique and entire narrower fascia near apical third and the 

 apex, rather broadly, yellow; abdomen with the yellow annuli much 

 wider than in obliteratus. Male rather more slender and cylindric, 

 with a still larger and more medially tumid prothorax, pale red- 

 brown in color throughout, the frontal tumidity similar, the pro- 

 thorax wider than the elytra, less arcuate or nearly straight in median 

 third at the sides and not at all tubulate at base, the surface still 

 more finely sculptured and densely opaque, the pale apical margin 

 very fine, the basal wanting, the vestiture consisting of minute, 

 sparse and very inconspicuous hairs; elytra with only the oblique 

 post-basal, post-median and apical spots and bands and these re- 

 duced; abdomen uniformly, closely pubescent, without condensed 

 pale annuli. Length (cf, 9) 15.0-16.0 mm.; width 4.4-5.0 mm.

Form nearly as in the preceding but a little smaller and notably more 

 slender, the red-brown color slightly more obscure in the male, 

 which has very much more suffused vestiture than in insignis, 

 sometimes almost completely obliterating the spots and fasciae; 

 front and triangular opaque spots nearly similar; prothorax nearly 

 similar in form and sculpture, even more tumid medially between 

 the more foveiform depressions just before the middle near outer 

 fourth, the short decumbent pubescence coarser, paler and closer; 

 elytra much narrower and somewhat less convex than in insignis, 

 with the same spots and fasciae as in the female of that species though 

 much reduced, the post-basal fascia but seldom wanting, the general 

 vestiture more or less dense and yellow and not rather sparse, fulvous 

 and less visible as it is in insignis; under surface wholly immaculate, 

 densely clothed with yellowish-tawny pubescence. Length (cf) 

 14.0-16.0 mm.; width 4.0-4.6 mm. California (Hoopa Valley, 

 Humboldt Co.) incongruens n. sp. 



4 Form throughout as in insignis, the female having nearly similar 

 coloration, the elytra more deeply black; frontal carinae fine but more 

 sharply defined, the surface between them more concave; prothorax 

 of similar form and vestiture, and likewise but very little wider than 

 long, except that it has the apical yellow band, not angularly 

 emarginate, but broadly and gently sinuate medially and the fine 

 subvermicularly rugulose sculpture a little coarser medially; elytra 

 but slightly wider than the prothorax, otherwise nearly as in in- 

 signis, except as above stated and in having the space between the 

 post-median and apical yellow fasciae less extended; apices similarly 

 obliquely arcuato-truncate, with the angle very obtuse and narrowly
