femora but slightly thickened ; tarsi slender, distinctly shorter 

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

 remainder. 



It is almost impossible to describe the remarkable double sur- 

 face 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 t3'pe of the entire subfamily ; it is also the most 

 minute representative within our faunal limits. The antenniB are 

 very similar in form to those of Trichopterj'x. 



1. A. yuccae n. si3. — Narrowly oval, polished, sparsely pubescent, piceous- 

 black, the head, pronotum, base of the elj^tra and two fascise just before the 

 middle and at apical fourth respectively, pale testaceous; legs and antennte 

 testaceous, the hind femora blackish except toward base and apex. Head 

 strongly iuflexed, convex, longer than wide, very minutely, sparsely punctate, 

 the eyes separated by one-half of their own width; antennae 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 abruptlj' 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 abundantly by 

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



OTIORHYNCHID.E. 



The known forms allied to Dyslobus have become ver}' nume- 

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

 constitute the most conspicuous and abundant otiorh3'nchide ele- 

 ment of the true Pacific coasi 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 

 genera as follows : —
