ably the example described is a female and the legs of the male may 

 be more robust. Nothing is known as to the variation of the color 

 of the legs, etc. 



Length 18 mm. (including exposed tips of wings). 



Hab.— Waianae Monntains, Oahn. Collected and given 

 to me by Mr. D. B. Knlins. I have seen trees of Pipturus 

 riddled by the larvae of this species in the same mountains, 

 but neglected to rear them. There it replaces CaUithmysus 

 koehelei of the Koolau ]\rountains. 



Plagithmysus ignotus sp. n. 



Of a dull red color, the legs concolorous, the bases of the femora 

 not being notably pale compared with their other part. Head with 

 very pale yellow pubescence, the pronotum with a very definite longi- 

 tudinal band of the same on each side of the median crest, while the 

 whole of its deflexed sides are similarly clothed. Consequently in 

 dorsal aspect it appears to have four definite longitudinal bands. An- 

 tennae long and slender, the apical joint being four or five times as 

 long as its greatest width. All the femora and tarsi with white, the 

 hind tibiae with black hairs. Elytra at the base with very pale yel- 

 low pubescence and behind this on a darker area with the usual pale 

 pubescent lines, divergent anteriorly. These lines are not continuous, 

 but each consists of a series of regularly placed, small, pubescent 

 spots, which form broken, but perfectly definite lines. Abdominal 

 segments at the sides each with a spot of very dense pale pubescence, 

 three similar spots continuing the series on each side of the thorax. 



Length 15 mm. I am not certain as to the sex of the 

 single specimen. It comes near to F. niunroi and P. aequahs, 

 but is quite distinct. 



Hab. — Kauai (3,000 feet). Given to me by my friend 

 Mr. G. C, Munro many years ago. 



Acalles cugeniae .sp. n. 



Head, thorax and basal half of the elytra covered with ferru- 

 ginous squamosity. The color is not uniform, being in some parts 

 nearly orange and in others shading into whitish-ochreous. The ros- 

 trum is red. On the head are some markings formed by black squa- 

 mosity; two small spots of the same color near the front margin of 

 the pronotum, and another in the middle of the hind margin. The 

 pale portion of the elytra enclose some black markings, tending to 

 form an irregular curved band. The deep black squamosity of their 

 apical half is at the sides continued right to the base (but this is 

 only seen in lateral view), while at the extreme apex the squamosity 

 is ferruginous. Femora black with a median pale ring and another 

 at their base, the tibiae black on the basal, pale on their apical por- 

 tion.
