Rostrum dull and very densely punctured (no doubt a male char- 

 acter) ; the first funicle joint of the antennae elongate, distinctly 

 longer than the elongate second joint and as long as the third and 

 fourth together, the third and following ones moniliform. Pronotum 

 from one-fourth to one-third longer than its basal width, with a strong 

 longitudinal elevation on each side of the middle, these corresponding 

 to the elevations of the second elytral interstices, the ridges irregular, 

 approximated in front, but much more distant behind; two other 

 ridges form most of the lateral outline of the pronotum in dorsal 

 aspect and correspond with the elevated fourth interstice of the elytra, 

 while an elevation on the deflexed sides forms a small part of this 

 lateral outline on each side at about the middle of the length of the 

 pronotum. Second, fourth and sixth interstices of the elytra strongly 

 and unevenly raised, the highest pointg notably clothed with erect 

 scales, so as to accentuate their height. Between each of the ridges 

 two rows of coarse punctures or fovae can be seen, though the whole 

 surface is densely covered with squamosity. 



Length, excluding the rostnim, 5 mm. 



Hab. — ]\[anoa Valley near Honohiln.* Bred from a dead 

 branch of Eugenia by my friend Mr. O. H. Swezey. Bred 

 examples of Acalles are difficult to compare with captured 

 specimens, which may be partly or largely denuded of their 

 clothing, but I believe the above to be distinct from any of 

 the Hawaiian type specimens, all of which I have examined. 



Dryotribus wilderl sp. n. 



Black, the antennae, legs and rostrum obscurely reddish. Like 

 the typical species of the genus, but much more slender and elongate, 

 the elytra being about three times as long as width at their base. 

 The pronotum also is more elongate and less coarsely punctured, and 

 the punctures of the elytra appear considerably coarser than those 

 of the pronotum, while the general surface of the elytra between the 

 punctures is much smoother or less corrugated. 



Length 3.5 mm. 



Hab.- — Midway Island. A single specimen was found in 

 a dead stem — not drift-wood — by Mr. G, P. Wilder, to 

 whom I am indebted for this interesting form. 



Hetevamphus swezeyi sp. n. 



Dark piceous or rufescent (when more or less immature), the 

 antennae, tarsi and more or less of the tibiae in mature examples 

 testaceous, the rostrum paler than the pronotum and elytra. 



*It has also been collected on Mount Tantalus by Mr. F. Muir, 

 and in Palolo Valley by Dr. H. L. Lyon. — Ed.
