TOMICINI. 365 



hairs. Prothorax nearly one-half longer than wide, sides parallel, base 

 broadly rounded, margined only near the side ; anterior half of disc 

 asperate with granules ; posterior half sti'ongly and tolerably densely 

 punctured, without distinct dorsal smooth space. Elytra with striae com- 

 posed of strongly impressed transverse punctures, interspaces wide, 1-7 

 smooth except near the declivity, where there are a few punctures ; outer 

 interspaces with punctures gradually becoming confused near the sides ; 

 declivity deeply concave, strongly and coarsely punctured, with the 

 sutural stria deeply impressed ; the teeth of the second and third inter- 

 spaces are small, but acute ; that of the fourth is larger, conical and sub- 

 acute ; that of the fifth is large, compressed and emarginate ; the inter- 

 val between it and the apical elevated margin is wide, and in some speci- 

 mens is marked by a single indistinct cusp ; the apical margin is long, and 

 its anterior angle is more prominent than usual ; the sutural angle is 

 slightly prominent, as is frequently the case in other species, a character 

 of no importance. The sutures of the antennal club are nearly straight, 

 slightly bent forwards at the sides. Length 6.6 mm. ; .26 inch. 

 Oregon. Found in abundance by Lord Walsingham. 



6. T. rectus, n. sp. 



This species resembles the preceding in form and color ; but is of smaller 

 size, and the prothorax is less deeply punctured behind, with a distinct 

 smooth medial space. The elytral striae and interstrial punctures are 

 similar, but the teeth of the declivity are quite different ; the cusps of the 

 second and third interspaces are small, but distinct and acute ; that of the 

 fourth is broad, compressed and closely united with that of the fifth, which 

 forms a prominent tooth at its posterior extremity, the anterior extremity 

 of this conjoined mass is not acute, but barely rectangular, and the apical 

 acute margin is a rather large acute tooth. The body is thinly clothed 

 with long yellow hair, especially in front and behind. The antennal club 

 is marked with three sutures, the first and second curved at the middle, 

 bent forwards at the side, and the third nearly straight. Length 4 mm.; 

 .11 inch. 



One specimen. New Mexico and two from Oregon. I should consider 

 these as badly developed specimens of T. plastographus, except for the dif- 

 ferences in the antennal club.

The elytral striae are composed of small, transverse punctures; the inter- 

 spaces are wide and flat, and are marked with only a few punctures near 

 the declivity; the latter is deep, strongly punctured, as in all the preceding 

 species, with the sutural stria deeply impressed; the tooth at the end of the 

 second interspace is small, but acute and distinct; that of the third is want- 

 ing; that of the fourth and fifth are acute, and connected by an elevated 

 ridge, behind them there is one acute compressed tooth, which is scarcely less 

 prominent, and this is followed after a narrow interval by the apical margin.
