Tanygnathus. 



Of this genus eight species are all that have as yet been 

 described, ^^z., four from the Old World tropics, two from 

 the New World tropics, one fi-om temperate Europe, and 

 one fi'om the Atlantic Islands, I here add three new 

 species to this number, and can state, moreover, that the 

 genus will be found ultimately rather rich in species, as 

 I have a number of other undescribed ones in mv collec- 

 tion, one of which is from Southern Australia, and several 

 fi'om Brazil. 



The genus is one of very considerable interest ; for it 

 was assigned by Erichson to the Tachyporini, by Kraatz 

 to the Quediini, and yet possesses certain points foreign 

 to both these groups, which appear to me to indicate 

 a third relationship with the Aleockarini. A careful exa- 

 mination of the structural characters of the species seems 

 to me indeed to be urgently needed before its nearest 

 relationship can be satisfactorily decided. 



1. Tanygnathus longicornis, n. sp. Rufescens, anten- 

 nis elongatis, apicem versus pallidis, elyti-is piceis ; abdo- 

 mine fortiter fere irregulariter punctato, longius pubescente. 

 Long. Corp. 2^ lin. 



Antennae very slender and elongate, not in the least 

 thickened towards the extremity; the basal joint yellowish ; 

 the next five or six darker, and the rest again paler. 

 Head obscure reddish, very narrow and elongate, smooth 

 and shining. Thorax obscure reddisli, narrowed to the 

 front, not quite so long as broad, with four very fine 

 punctures placed as usual in this genus. Elytra darker 

 in colour than the head and thorax, scarcely so long as 

 the latter, closely and very finely pimctured. Hind body 

 reddish, with faint iridescent refiections ; the base of each 

 segment finely punctured ; the other part of each segment 

 \v\\\\ s])ai-ing, i-atlier large elevated points ; its pubescence 

 ratlu'i- long, and much mixed with black erect setfe. 

 Legs reddish. 



One specimen ; the only locality indicated being 

 " Amazons."
