any of Lacordaire’s tribes, being neither Phan^rognath nor Ad^lognath. 
Tarsi narrow : general facies of Trachyphlmus. C. cryptopSy p. 27, 
New Mexico. 
Amnesia, p. 48. Part of Dyslohus, Lee., but with the first suture of 
abdomen arcuate. Provisionally retained here as a lead to the Phyto- 
scaphides. Type, D. granicollis, Lee,, also D. decoraiiis, Lee., and 
A. ursina, Oregon, and rauca, California, p. 61, alternata, Montana, 
sordida and decidua, California, p. 52, and elongata, p. 53, California. 
Sciopithes, p. 62. Otiorrhynchides vraies, but with scrobes superior, 
cavernous, and oval. Represents the S. African Sciobius. Type, Sciop. 
obscurus, p. 63, California, &c. 
Agronus, p. 63. Allied to Paramira, differing in its shorter scrobes 
and more slender antennse. Differs from Sciopithes in having no spurs 
to hind tibisD, no mucro to middle and front tibisB, &c. A. cinerarius 
and deciduus, p. 64, California. 
Ncoptochus, p. 64. Differs from Ptochus in its broad intercoxal pro- 
cess and free claws. For P. adspersus, Sch. (being, with the 7 genera 
next recorded, included in the author’s Periteli). 
Thricolepis, p. 68. Closely allied to Peritelus, but clothed with scales 
and setae, also with much shorter scrobes, which are very decidedly cou- 
vergent above; and with non-divergent rostral alae and shorter antennae. 
Also allied to Mylacus, which, however, is pubescent. T. inornata, N. 
California to Utah, and T. simulator \_-trix], California, p. 69. 
Peritelopsis, p. 70. Possibly might enter one of Seidlitz's groups of 
Peritelus, to which it is doubtless very near. The alae of the rostrum are 
not at all divergent, and the rostrum is very short. For Ptochus globi- 
ventris, Lee. 
Geoderces, ibid. Seems allied to Epiphaneus ; resembles Trigonoscuta, 
with a somewhat narrower thorax : hind tibiae with 2 short fixed spurs. 
Type, Trachyphloeus melanothrix, Kby. ; also G. incomptus, p. 72, San 
Francisco to Vancouver. 
Aragnomus, p. 72. Differs from the preceding in having the scape 
much shorter than the funicle, and the tibiae not denticulate. Of doubt- 
ful position, near Sciobius in its frontal impression: scrobes neither 
superior nor lateral. For A. griseus, ibid., California. 
Dysticheus, p. 73. Scrobes superior, slightly convergent above, more 
open for their entire extent than in any known genus. Eyes indistinctly 
surrounded by a groove. Resembles no non-American genus. D. insignis, 
ibid., California. 
Eucyllus, p. 74. Near Trachyphloeus. Differs from Dysticheus in its 
deep, lateral, not at all convergent scrobes. E. vagans, ibid., Arizona 
and California. 
Thinoxenus, ibid. Differs from Eucyllus in its feebly arcuate scape 
and the structure of its funicle ; also in its shorter scrobes, which are 
shallow behind, and slightly convergent above. T. squalens, p. 75, Cali- 
fornia. 
Rhypodes, p. 75. Exactly of the form of Trachyphloeus. Eyes very 
feebly prominent, scarcely visible from above, orbital groove very well 
defined ; differs from Thinoxenus in its deep scrobes, which reach the 
1876. [vOL. XIII.] I 6
