Coleopterological Notices, VI. 813 



The single specimen is apparently a female, judging b}' the 

 rather obese form of the body and the corresponding form of 

 the fifth ventral in the female of segnis, but the tip of the ovipos- 

 itor is very acute and corneous. 



AilI3IESIA Horn. 



This genus is very closely allied to Dyslobus, but ma}?- be dis- 

 tinguished not only by the alternatel}^ convex elytral intervals, 

 but by the greater prominence of the ocular lobes ; there is con- 

 siderable variation in the latter character, however, as is gener- 

 ally the case within generic limits, and the lobe is very much 

 shorter and less distinct in scidptilis than in tumida. The species 

 known to me may be thus outlined : — 



Elytra sparsely but strongly tuberculose throughout, the sutural prominence 



at the summit of the apical declivity very pronounced tumida 



Elytra not tuberculose, the sutural prominence moderate or feeble. 

 Antennal funicle very long, much longer than the beak. 



Body stout, convex ; intervals tesselate with large black areas through- 

 out the length granicollis 



Body slender, at least in the male; elytral vestiture not much varie- 

 gated. 

 Legs black, the anterior femora distinctly elongated in the male. 



discors 



Legs red, the anterior femora not elongated in the male. ...sculptilis 



Antennal funicle much shorter, scarcely longer than the beak ; anterior legs 



notably elongated in the male; body much smaller debilis 



A. granicollis Lee. (Ann. Mag. Nat. Hist., 1869, p. 380,— Dyslo- 

 bus), is northern in distribution, occurring in Vancouver Island 

 and Oregon. A. sculptilis Csy. (Ann. N. Y. Acad. Sci., lY, p. 

 250), occurs in California to the northward of San Francisco. 



The serial punctures in Amnesia are never squamigerous, each 

 puncture having in all cases a small hair arising from its anterior 



margin. 



A. tumida n. sp. — Ovoidal, moderately convex above, black, the an- 

 tennte and tarsi piceo-ruf ous ; vestiture consisting of small rounded scales 

 densely disposed in the interspaces between the shining tubercles, pale brown- 

 ish in color and intermingled throughout with numerous short sub- erect hairs, 

 the scales on the head and beak becoming long, slender and sparse. Head 

 fully one-half as wide as the prothorax, the entire surface of the head and 

 beak coarsely and densely punctato-rugose ; transverse impression distinct; 

 eyes separated by scarcely more than twice their own width; beak stout and 

 thick, strongly dilated at apex, thinner in profile toward base, scarcely two-
