244 FAUNA HAWAIIENSIS 



rather large development of the rostrum in the ^, and in the same sex the posterior 

 coxae are much less widely separated than in many species, much less widely than the 

 front pair. In the % the distance between the hind coxae is greater, so that it does not 

 greatly differ from the majority of species in this respect. 



Hab. Oahu, Molokai and Lanai ; attached to Wikstroemia. 



(ii8) Proterhinus alyxiae, sp. nov. 



Latus, brevis, robustus, ferrugineus, pulcherrime squamosus. Antennae elongatae, 

 articulis basalibus notabiliter robustis (secundo subquadrato), clavam versus sensim 

 gracilescentibus, clava gracili, vix evidenter 3-articulata. Pronotum trans medium latis- 

 simum, perinaequale, antice transversim fortiter impressum, parte posteriore fortiter 

 elevata, antice posticeque ferrugineum, caetera parte densissime pallido-squamosa. 

 Elytra brevia, lata, submaculatim squamosa, setisque albidis erectis conspersim vestita, 

 dorso juxta basim impresso, ibique nigricante, basi emarginata, humeris productis. 

 Femora omnia fortiter incrassata. Z ?• Long, vix 3 — 3 '2 mm. (Plate IX. fig. 23, ^.) 



Var. pauper. $ $ antennis gracilioribus, ? statura multo minore et forma graci- 

 liore distinguenda. $ $. Long. $ 275, $ 2 mm. 



This beautiful species, on account of its short, wide form, reminds one at first sight 

 of some Kauai species. It is not really closely allied to these, however, but it is so to 

 P. calliphyas of Maui. It is distinct from that species by the accentuation of most of 

 those characters, which render the latter remarkable. The distinction between the 

 dorsum and flanks of the prothorax is clearly marked by the sharp edge formed at their 

 meeting. 



Hab. Molokai mountains (3000 ft.); rare, taken from stems oi Alyxia. Four 

 females (var. pauper) taken on Lanai are only half or less than half the size of the 

 smaller Molokai examples, and have much more slender antennae. The single <J taken 

 with these is about as large as the type, but its antennae are decidedly thinner. 



(119) Proterhinus navita, sp. nov. 



Haud latus, rufescens, sat dense pallide squamosus, elytris saepe plus minusve 

 nigro-notatis. Antennarum ^ articuli 2 basales perconspicue robusti, nigricolores ; 

 articuli sequentes graciliores, plerumque evidenter, sed minute, tuberculati, clava parum 

 distincte 3-articulata (sive fere 2-articuIata). Pronotum densius aureo-squamosum, antice 

 plus minus impressum. Elytra aureo- vel griseo-squamosa, setisque brevissimis nonnullis 

 erectis inconspicue vestita, angulis humeralibus obscuris. Tarsorum anticorum articulus 

 secundus minor, lobis minoribus. ^ $. Long. i'5 — 3 mm.
