2i8 FAUNA HAWAIIENSIS 



(69) P roterhinus bi'evipennis, sp. nov. 



Rufescens vel rufo-piceus, antennis pedibusque totis, vel ex parte, rufis, pallide 

 squamosus, forma breviore. Antennae graciles. Oculi prominentes. Pronotum sat 

 dense aureo-squamosum, antice fortiter angustatum, aut nonnumquam abrupte con- 

 strictum, profunde 3-impressum, medio longitudinaliter subsulcato, antice et ad latera 

 setis curvatis suberectis, sat conspicuis, vestitum. Elytra rufescentia, pallide squamosa, 

 parte apicali nigra vel nigro-maculata, dorso plus minusve inaequali, irregulariter 

 punctato, setis erectis brevibus longioribusque intermixtis sat conspicuis, humeris fortiter 

 productis. Femora minus fortiter incrassata. tt- Long. 2 '5 — y2 mm. 



A variable species, typical examples of which are easily distinguished. The basal 

 two-thirds of the elytra are covered with pale squamosity (except generally on some 

 black spots), and this pale portion is often flattened or subdepressed, between the more 

 or less evident longitudinal ridges. In well-developed examples there are also traces of 

 transverse ridges. The puncturation has a peculiarly irregular appearance. The 

 antennae are quite slender, clear red except at the apex, but not very long. The eyes 

 are of moderate size and prominent, and there is more or less trace of a dividing ridge 

 between the vertex and front of the head. The rostrum of the % is finely longitudinally 

 rugulose and dull. The femora are not very strongly clavate. The coxae are all 

 equally widely separated, and the basal segment of the abdomen beneath has a dull and 

 densely and minutely granulate appearance. 



Hab. Maui, Haleakala (5000 ft.); about two dozen examples taken. 



(70) Proterhinus epichrystis, sp. nov. 



Rufo-niger, elytris rufescentibus, plus minusve nigro-maculatis. Antennae 

 graciles, sat elongatae. Oculi fortiter prominentes. Frons capitis a vertice carina 

 distincta transversa separata. Pronotum squamis pallidis aureis densius vestitum, 

 fortiter 3-impressum, setis suberectis curvatis ad latera conspicuis. Elytra nigro- 

 maculata, pallide squamosa, setisque albidis elongatis conspicue vestita, fortiter punctata, 

 fere aequaliter convexa, sutura elevatula, basi scutellum juxta utrinque tuberculata, 

 humeris fortiter acute productis. ^ $. Long. 27 — 4 mm. 



A rather large species, but very variable in size, ill-developed examples being only 

 about one-third or one-fourth the bulk of the larger ones. The head and thorax are 

 densely clothed with a very pale golden squamosity, the eyes are strongly prominent 

 and usually of conical shape, the antennae elongate and slender with well-marked 

 3-jointed club. Thoracic impressions deep and distinct. Elytra red with black 

 markings, coarsely punctured, the longitudinal ridges little or not at all evident, tubercu- 

 late at the base on either side near the scutellum, the humeral angles strongly produced
