232 FAUNA HAWAIIENSIS 



(95) Proterhimis convexiusculus, sp. nov. 



Nigricans (nonnunquam rufescens), elytris plerumque plus minus rufescentibus, sat 

 convexis, pallide aureo-squamosus. Oculi magni, prominentes. Pronotum pallide 

 squamosum, forma variabili, impressionibus sat profundis (nonnunquam lutoso-repletis), 

 medium saepe longitudinaliter subsulcatum. Elytra sat convexa, pallide aureo- vel 

 griseo-squamosa, squamis baud remotis minus distincte punctata, angulis ipsis humerali- 

 bus fortiter acute productis, sutura elevatula, setis erectis parce conspersis. Abdominis 

 segmentum primum ventrale subtiliter granulatim asperulum. ^ %. Long. 2 '6 — 3 "5 

 mm. 



A variable species, individuals differing a good deal in size, colour, and distribution 

 of the squamosity, as well as in the length and thickness of the antennae, &c. I have 

 had some doubt as to whether it can be absolutely separated from that excessively 

 variable species P. integer of Lanai, but have thought it better to keep the two apart. 

 One almost entirely black example of this species has been taken, even the antennae 

 being entirely of that colour, and only the tarsal lobes are piceous, and this individual 

 has the elytra covered with grey squamosity. Usually the squamous covering is 

 co-extensive with the red colour of the wing-cases, which typically are red at the base 

 and there squamose, the apical dark parts being nearly free from squamosity, the extent 

 of the red colour and squamous covering varying together. In P. convexiusculns it 

 may be observed there is little or no trace of a transverse ridge between the front and 

 vertex of the head. 



Hab. Molokai, mountains, generally at an elevation of about 4000 ft. Numerous 

 examples were taken, but many of them are in indifferent condition. 



(96) Proterhimis echinoides, sp. nov. 



Nigricans, elytris rufis, nigro-signatis, tibiis tarsisque rufescentibus, antennis fere 

 nigris, pallide squamosus. Antennae breviores, subcrassae, clava 2-articulata. Oculi 

 magni. Pronotum minus profunde 3-impressum, medium dense, latera versus minus 

 dense, squamis pallidis vestitum. Elytra sat fortiter et fere aequaliter convexa, squamis 

 pallidis necnon setis multis elongatis erectisque perconspicue vestita, basi scutellum 

 juxta utrinque tuberculata, angulis humeralibus fortiter productis. Femora omnia cum 

 tibiis setis elongatis pallidis conspicue vestita, tarsorum anticorum lobis sat minutis. ^. 

 Long. 2 '5 — 27 mm. 



A small species, but very easily recognized by the unusual development of the 

 erect setae on the elytra and legs, the short stout antennae, with the club hardly more 

 than 2-jointed, large eyes, small tarsal lobes, and nearly evenly and somewhat strongly 

 convex elytra. One example has the antennae rather more elongate than the others. 



Hab. Molokai, mountains (3000 ft.) ; three males taken in June 1896.
