PhlcBopora cingulata, n. sp. Depressa, angustula, pa- 

 rallela, parum iiitida, omnium siibtilissime punctulata et 

 pubescens, testacea, capite, pectore, elytris, abdominisque 

 cingula, fuscis : antennis incrassatis. Long. I ^ mm. 



Antennas short and stout, much thickened towards the 

 apex, yellow; 3rd joint quite small, 5 — 10 strongly trans- 

 verse. Head about as broad as thorax, with the sides 

 and vertex rectangular; it has a rather obscure longitu- 

 dinal impression along the middle, its punctuation is quite 

 indistinct, but the surface is dull, and its colour is in- 

 fuscate yellow. Thorax quadrate, parallel-sided, about 

 as broad as the elytra, yellow, dull, punctuation exces- 

 sively indistinct. Elytra considerably longer than the 

 thorax, of an obscured yellow colour, quite dull. Hind 

 body narrow and parallel, yellow, with an infuscate ring 

 before the apex. Legs yellow. 



I have a single individual, which was found under bark 

 near Honolulu. 



This and the P. dihita, though excessively closely 

 allied, will prove, I think, to be two distinct species. 

 Although very much smaller and more depressed than 

 our Eui-opean PhlceoporcB, they present the characteristic 

 form of their head and thorax ; the Hawaiian species 

 depart, however, from the European ones, by their middle 

 coxge being quite contiguous, and in this respect they 

 agree with the two Australian insects (P. Iceviuscula and 

 P. gratiosti) assigned by Fauvel to the genus Phlceopora; 

 one of these Australian insects, P. gratiosa, is, in fact, 

 in size, form and colour, remarkably intermediate between 

 the European and Hawaiian insects. 



Plilceopora diluta, n. sp. Depressa, angustula, paral- 

 lela, parum nitida, omnium subtilissime punctulata et 

 pubescens, testacea, abdomine ante apicem infuscato ; 

 antennis brevibus, sat incrassatis. Long. 1^ mm. 



This species is very closely allied to P. cingulata, but 

 it is less variegate in colour, and the antennge are not 

 quite so stout. 



The single individual sent by Mr. Blackburn was found 

 in decayed wood in the mountains of Kauai.
