femora but slightly' thickened ; tarsi slender, distinctl>^ shorter 

 than the tibioe, the basal joint very much longer than the entire 

 remainder. 



It is almost impossible to describe the remarkable double snr- 

 foce at the posterior margin of the head in an intelligible manner, 

 and, in view of this very aberrant structure, as well as the abnor- 

 mal anterior parts of the head and the broad base of the pro- 

 thorax, we must regard Axylophilus as the most specialized and 

 extraordinary type of the entire subfamily ; it is also the most 

 minute representative Avithin our faunal limits. The antemiie are 

 very similar in form to those of Trichopteryx. 



1. A. yuccae n. sp. — Narrowly oval, polished, sparsely pubescent, piceous- 

 black, the head, pronotiim, base of the elytra and two fascia; just before the 

 middle and at mncal fourth respectively, pale testaceous; legs and antennae 

 testaceous, the hind femora l:»lackish except toward base and apex. Head 

 strongly inflexed, convex, longer than Avide, very minutely, sparsely punctate, 

 the eyes separated by one-half of their own width; antenna; about one-half 

 as long as the body. Prothorax four-fifths wider than long, very much wider 

 than the head, the sides feebly convergent and nearly straight almost to the apex, 

 then abrui^th' rounded and narrowed, the apex scarcely two-thirds as wide as 

 the base, the latter transversely truncate, with a small and feeble sinuation at 

 the scutellum; basal angles nearly right but blunt; disk moderately convex, 

 subexplanate toward the basal angles, strongly and rather closely punctate. 

 Scutellum transverse, feebly trapezoidal, polished. Elytra two-fifths longer 

 than wide, Just behind the middle two-fifths wider than the prothorax and 

 distinctly wider than at base ; sides arcuate ; apex obtuse and subtruncate ; disk 

 scarcely visibly impressed near the base, strongly punctate, the punctures well 

 separated. Abdomen more finely and densely punctate and pubescent toward 

 apex. Length 0.75-0.9 mm. ; width 0.45-0.5 mm.

This exceedingly interesting species was taken al)undantly by 

 Messrs. Hubbard and Schwarz, on plants of the genus Yucca. 



OTIORHYNCHID.E. 



The known forms allied to Dyslobus have become very nume- 

 rous by reason of recent collecting on the west coast, where they 

 constitute the most conspicuous and abundant otiorhynchide ele- 

 ment of the true Pacific coast fauna; they are especially nume- 

 rous and diversified in northern California and in Oregon. The 

 larger and more striking of these species, which I have set apart 

 for investigation at the present time may be assigned to four 

 o;enera as follows : —
