100 Mr. D. Sharp on some 



more insignificant-looking allies. I have named this 

 remarkable little beetle in honour of the distinguished 

 entomologist of Philadelphia, who has so indefatigably 

 and successfully added to our knowledge of the Coleoptera. 



Proterhinus paradoxus, n. sp. Oculis minutis ; parum 

 elongatus, ferrugineus, subnitidus, sine setis depressis, 

 setis erectis elytrorum sparsis, sed conspicuis ; prothorace 

 injequali, anterius conspicue constricto, obsolete punctato, 

 sparsim hispidulo ; elytris planatis, lateribus rectangu- 

 lariter deflexis, omnium fortiter, dense punctatis, humeris 

 depressis, inconspicuis; femoribus parum clavatis. Long. 

 2 1 mm. 



The antennas are rather slender, but have the 2nd joint 

 thicker than usual ; the thorax is rather small, the three 

 impressions are very large, the anterior one is particularly 

 indefinite, and cannot be said to be limited laterally, and 

 it is to this that is due the greater apparent constriction 

 of the front part of the thorax ; the punctuation is very in- 

 distinct, and the surface is rendered hispid by curled 

 suberect seta3. The elytra have the whole of the dorsal 

 portion quite flat, there is an appearance of an obsolete 

 tubercular elevation at the base on each side near the 

 scutellum, the lateral portions of the wing cases are placed 

 quite at right angles to the disc ; the punctuation is very 

 deep and coarse and close. 



Two individuals have been found in the mountain 

 forests near Honolulu; sent as No. 163. 



Obs. — This species is so very distinct that, if con- 

 necting links are not found, it will have to be treated as a 

 distinct genus. The minute eyes indicate an inactive life. 

 The very different sculpture and clothing, and the peculiar 

 form of the wing cases, are accompanied by a diminution 

 of the 2nd joint of the tarsi and a remarkable develop- 

 ment of the sutures of the ventral segments, which are 

 very coarse and deep. The individual described is pro- 

 bably the unrostrate sex, but, if so, it has the head 

 narrower and more rostrate than in the unrostrate sex of 

 other species, and I shall not be surprised if it prove that 

 in this species the sexual diflferentiation of the head is less 

 than in the other Protcrhini.
