COLEOPTERA

and acute. Their clothing consists of pale squamosity, which is not very dense, and is 

 absent from the dark markings, and numerous elongate white, erect setae, which are 

 conspicuous. The femora are not very stout, the lobes of the tarsi are somewhat 

 variable in size, but never very largely developed. The rostrum in the % is short, 

 generally slightly narrowed to the apex, and the head in both sexes has a very distinct 

 transverse ridge (rarely interrupted) between the vertex and the front. All the coxae 

 are widely, and about equally, distant, the basal ventral abdominal segment is minutely 

 granular, rather than punctured. 



Hab. Maui, Haleakala (5000 ft.) ; about 40 examples were taken.

Niger, pedibus antennisque rufescentibus. Caput post oculos constrictum, his 

 fortiter prominentibus. Antennae graciliores. Rostrum % fere opacum, crebre longi- 

 tudinaliter rugulosum, lateribus parallelis. Pronotum elongatum, lateribus subaequaliter 

 rotundatis, distincte 3-impressum, impressione antica lata, duabus posticis rotundatis. 

 Elytra elongata, parce pallide squamosa, setisque erectis albidis parcius vestita, fortiter 

 punctata, ad basim scutellum juxta utrinque tuberculata, fere aequaliter convexa, humeris 

 peracute fortiter productis. Femora minus fortiter clavata, subgracilia, lobis tarsorum 

 anticorum minoribus. $. Long. 3'5 mm. 



Only a single $ of this species was collected, and it appears to be most nearly 

 related to P. epichrysiis of the Maui species, but more closely still to P. lanaiensis of 

 Lanai. In colour it is entirely black, except for the dark reddish legs and the rather 

 more brightly coloured basal joints of the antennae. The transverse ridge between the 

 vertex and front of the head is very distinct, the eyes are strongly prominent. The 

 basal of the three joints of the club of the antennae is not very much more developed 

 than the preceding, so that the club is not very distinct. The anterior impression of 

 the elongate thorax is large and vague, the two posterior ones small, round, and definite. 

 The elytra are long, nearly parallel-sided for more than half their length, with traces of 

 the two longitudinal ridges, at least in certain aspects. All the femora are somewhat 

 slender, and the lobes of the front tarsi are decidedly small for the size of the insect. 



Hab. Maui, Haleakala. A single ? was taken on April ist, 1894, at an elevation 

 of about 5000 ft.

Nigricans vel piceo-niger, tibiis tarsisque obscurius rufescentibus. Oculi magni,
