2 26 FAUNA HAWAIIENSIS 



is entirely or to a large extent covered with an exudation, which altogether conceals or 

 very much changes the appearance of the sculpture. Generally the insect is red, with 

 dark lateral markings on the elytra, but some examples are nearly entirely blackish or 

 piceous, with black antennae. Small individuals with slender antennae certainly closely 

 approach the Oahuan P. oscillans, but I cannot consider the two species identical. 

 Length 2 — 3 mm. 



Hab. Maui, Haleakala (4000 — 5000 ft.) ; upwards of seventy examples of this 

 species have been examined. 



(83) Proterhimis epiinelas, sp. nov. 



Nigricans, tibils tarsisque et rarius femoribus rufescentibus, maculatim pallide 

 squamosus. Oculi parvi. Antennae graciles, articulo secundo elongato, haud minus 

 longo, vel etiam (praesertim in %) nonnunquam longiore quam tertius. Pronotum 

 antice depressum, lateribus fortiter rotundatis, setisque curvatis marginatis, utrinque 

 plaga sublaterali densissime albido-squamosa. Elytra maculatim squamosa, parcissime 

 albido-setulosa, punctata, humeris parum distinctis. ^ $. Long, vix 2 — 2"5 mm. 



A small species, remarkable for its dark colour, the tibiae and tarsi alone being as a 

 rule of a red or pitchy colour, and for the elongation of the second joint of the antennae, 

 which is subequal to the third in length, or not infrequently decidedly the longer of the 

 two. The prothorax is very densely squamose towards the sides, less so towards the 

 middle. The elytra have no longitudinal ridges, but are more or less perceptibly, 

 though vaguely, impressed transversely a little behind the base, and therefore have a 

 slight appearance of elevation at the extreme base in the region of the scutellum. The 

 humeral angles are obscure. 



Hab. Maui, Haleakala (5000 ft.) ; an extensive series taken. This insect varies 

 a good deal in size, but is never a large and often a minute species. 



(84) Proterhinus 7'ujicollis, sp. nov. 



Rufescens, elytris nonnunquam plus minusve nigro-marginatis, supra rarius nigro- 

 infuscatis, parum dense squamosus. Antennae graciles, sat elongatae, ruficolores, 

 articulis apicalibus nonnunquam nigricantibus. Pronotum plerumque (^ saltem) sat 

 latum, medium parce, latera versus densius, aureo-squamosum, vix evidenter punctatum, 

 antice transversim impressum. Elytra irregulariter nee dense squamosa, squamis 

 saepe maculas minus distinctas rotundatas formantibus, dense et sat distincte punctata, 

 setis erectis evidenter vestita, angulis humeralibus haud acutis. Femora postica minus 

 fortiter clavata, lobis tarsorum anticorum parvis. ^ %. Long. r8 — 2*2 mm.
