With the general outlines of fiavocastaneus, but much 

 darker, punctures much more conspicuous, and elytral fasciae 

 in somewhat different positions : the first is oblique from each 

 shoulder to the suture (with the scutellar region infuscated), 

 and the second is at the apical third, not quite touching the 

 sides or suture. It is apparently closer to alpicola than to 

 any other described species, but is narrower, more parallel- 

 sided and darker, with very different markings; from mundus 

 it differs in being narrower and more convex, with different 

 markings and pubescence. I have been unable to see the 

 front legs clearly, but the middle tibiae are somewhat sinuous 

 near apex. Each eye, as seen from directly in front, occupies 

 only about one-fifth of the width of head. 



Xylophilus dolichoderes, n. sp. 



cf . Flavous, with markings varying from light brown 

 to black. Clothed with very short pubescence, varying from 

 white to brown. 



Head wide; punctures partially concealed. Eyes large, 

 prominent, not very close together, and feebly notched. 

 Antennae rather long and thin, second joint small but slightly 

 longer and thicker than third, fourth-tenth subequal in 

 length, eleventh irregularly subovate, not as long as ninth 

 and tenth combined. Prothorax slightly longer than wide, 

 sides feebly dilated from base to near apex, and then strongly 

 narrowed; with dense but partially-concealed punctures; 

 with two subcontiguous, small, medio-basal impressions. 

 Elytra depressed, much wider than prothorax at base, sides 

 gently but distinctly dilated to beyond the middle, with a 

 shallow but fairly long depression on each, commencing at 

 base near the shoulder; with dense and rather small punc- 

 tures, becoming still smaller posteriorly. Legs rather long 

 and thin; hind femora moderately stout, with a short sub- 

 basal fringe on lower surface; hind tibiae rather thin (but 

 stouter than the others), no wider at apex than in middle. 

 Length, 2 mm.

 Type (unique), I. 6199. 



Structurally a distinct species ; but the colours are 

 probably variable. The head and prothorax are of a rather 

 deep red, with the sides of the prothorax black, but appear- 

 ing slaty-grey on account of the pubescence ; the elytra are 

 flavous but with irregular light brown markings occupying 

 most of the basal two-thirds, the suture close to the scutellum 

 is blackish, near the suture on the basal two-thirds there 

 are some irregular patches of pale pubescence ; the under- 

 surface, hind femora, and base of hind tibiae are blackish,
