662 FAUNA HAWAIIENSIS 



Proterhimis vestitus Sharp. 



P. vestitus Sharp, huj. op. ii., p. 205. 



This is a very distinct species with the antennae ahvays unicolorous red, or at most 

 a little darker apically and the pronotum generally abruptly constricted in front. It 

 varies considerably in size, the antennae are sometimes shortened, and the proportion 

 of black and red colour of the elytra is also variable. I have seen some specimens 

 entirely red with only faint fuscous markings on the elytra. The species is very easily 

 recognized. 



Hab. Oahu ; in the mountains around Honolulu, but I did not take it elsewhere 

 on the island. It chiefly affects Aleurites, Piptzirus and Pisonia and is not found on 

 the highest peaks. 



(9) Prote7'hinus transversalis, sp. nov. 



Rufescens, thorace plus minusve infuscato, elytris nigro-maculatis, antennarum clava 

 nigricante. Antennae graciles, fortius elongatae, clava 3-articulata ; oculi minores. 

 Pronotum parum latum, aureo-squamosum, antice fortissime transversim impressum, 

 impressionibus posterioribus rotundis, minus profundis. Elytra latiuscula, remote 

 punctata, setis albidis erectis perparce sed conspicue vestita, humeris fortiter acute 

 productis. Long. % circiter 2 mm. 



This species is very distinct from any other on Oahu. The example examined 

 is not quite mature and I suspect undersized; so that the characters observed are likely 

 to be accentuated in larger individuals. 



Hab. Oahu ; Waianae mountains 2000 ft. 



(10) Protcrhmns excrucians, sp. nov. 



Under the name of P. simplex Sharp I formerly placed a number of specimens, 

 which I considered might be referred to that species as large and well-developed 

 individuals. P. simplex was originally described from two apparently immature males, 

 and other specimens afterwards sent over by Mr Blackburn were referred to it by 

 Dr Sharp, though superficially at least they did not resemble the type. Whether 

 Mr Blackburn ever obtained additional examples agreeing with the type is doubtful, 

 and I have never myself seen any. I therefore propose the above name for the 

 specimens which I formerly considered to be P. sit)iplex S., as I no longer believe that 

 the two are the same species. In any case P. excrucians remains so variable, even 

 if the small and narrow examples be removed and considered as varieties of true 

 P. simplex, that I am at a loss to characterize it better than I have already done under 

 P. simplex in the earlier part of this work. 



Hab. Oahu ; abundant near Honolulu and throughout both mountain ranges.
