152 INSECTS OF THE FLY RIVER, NEW GUINEA, "COLEOPTERA." 



88. Cladophorus longicornis, n. sp. 



This species differs from 0. ingenuus, in being much larger, in 

 having the antennae longer and more largely branched, in having 

 the scutellum and the whole under surface black, and in having 

 the elytra ampliated towards the apex. Length, 7 lines. 



89. Cladophorus apicalis. n. sp. 



This is also very close to C. ingenuus, and differs from the last- 

 ed, longicornis in having the scutellum the same colour as the 

 elytra, in having the extreme tips of the elytra brown, and in 

 having the underside of the thorax and basal tips of the thighs 

 yellow. Length, 7 lines. 



90. Cladophorus nigrescens. n. sp. 



Black, antennae flat and toothed in the female, much branched 

 in the male. Head and thorax nitid, scutellum black. Elytra 

 with the base and costae red ; the apex and the spaces between the 

 costse dark. The bases of the thighs are yellowish. Length, 



4 lines. 



91. Cladophorus semirufus. n. sp. 



Narrow, elongate, black or bluish-black all over with the excep- 

 tion of the basal two-thirds of the elytra, which are of a brick red ; 

 the intermediate costae are near the base almost as large as the usual 

 large costee. 



Length, 3^ lines. 



92. Trichalus pallidipennis. n. sp. 



Brownish black, the thorax, scutellum, elytra and base of thighs 

 dusky yellow. The antennae are long and compressed, and little 

 dentate, the discoidal areolet of the thorax is narrow, the others 

 are not traceable. 



93. Trichalus apicalis. n. sp. 



I am in some doubt as to the genus of this insect. The colour 

 is bluish black, with the thorax, scutellum, basal two-thirds of the 

 elytra, the under side of the thorax and the base of the thigh,
