220 FAUNA HAWAIIENSIS 



latioribus, angulis apicalibus posterioribus productis, 9°, 10° et 11° his evidenter gracili- 

 oribus. Pronotum 3-impressum, lateribus subfortiter rotundatis. Elytra subsquamosa, 

 setisque erectis pallidis vestita, longitudinaliter subcarinulata, sutura subelevata, basi 

 scutellum juxta utrinque tuberculata, humeris acute fortiter productis. Femora 

 antica fortiter incrassata, lobis tarsorum maximis. ^. Long, vix 4 mm. (Plate IX. 

 fig. 21. Z.) 



This very remarkable species cannot be confused with any other, on account of the 

 structure of the antennae, the middle joints of which are produced at their hinder apical 

 angles, and are actually wider than the terminal ones, which usually form the club. 

 The front and vertex of the head are not divided by any evident ridge, the eyes are 

 strongly prominent, and the tarsal lobes of the front feet very large. The elytra when 

 closely examined are seen to have each a fine ridge about midway between the suture 

 and lateral margin. These ridges are a good deal more evident in one of the examples 

 than in the other, and the development of the antennae also is decidedly greater in one 

 of the two specimens. 



Hab. Maui, Haleakala. Two male examples taken at an elevation of 5000 ft. in 

 October, 1896.

Niger, statura majore, antennis pedibusque nigricantibus. Antennarum articulus 

 primus brevis et robustus, secundus vix longior quam latior, caeteris elongatis, clava 

 elongata distinctissime 3-articulata. Oculi permagni, fortiter prominentes. Pronotum 

 squamosum, lateribus setis conspicuis erectis curvatis vestitis, fortissime 3-impressum, 

 medium longitudinaliter subsulcatum. Elytra variegato-squamosa, grossissime rugoso- 

 punctata, basi scutellum juxta utrinque tuberculata, setis gracilibus erectis conspicue 

 vestita, sutura subdepressa, humeris fortiter productis. Femora antica sat incrassata, 

 lobis tarsorum parvis. ^. Long. 4 mm. 



A large species, with very large eyes, antennae thick at the base, but becoming 

 slender before the club-joints, and unusually small lobes to the second joint of the front 

 tarsi. Thorax deeply impressed in the middle in front, and this impression connected by 

 a longitudinal groove with a postero-median impression, the two sublateral impressions 

 very deep and distinct, and rather large, the hind angles marked by a distinct spot of 

 white squamosity. Elytra uneven, submaculately squamose, impressed between the 

 basal tubercle and the strongly produced humeral angle on either side, the puncturation 

 extremely coarse and rugose, the sutural portion subdepressed. The fine erect setae 

 of the elytra and the curved ones on the prothorax unusually conspicuous. Tibiae 

 with the setae short and somewhat dense. 



Hab. Maui. A single ^ taken on Haleakala in April, 1894, at an elevation of 

 less than 4000 ft.
