 existent, must be very slight. 



Tanygnathus. 



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

 described, viz., four from the Old ^^'orld tropics, two fi'om 

 the New AYorld tropics, one from temperate Eurojje, and 

 one from 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 my collec- 

 tion, one of which is from Southei*n Australia, and several 

 from J Brazil. 



The genus is one of very considerable interest ; for it 

 was assigned by Erichson to the Tachyporini, by Ki'aatz 

 to the Quediini, and yet possesses certain points foreign 

 to both these groups, which appear to me to indicate 

 a third relationship with the Aleocliarini. 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. 



Antennre 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 reddish, narrowed to the 

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

 piinctm-es 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 punctured. Hind body 

 reddish, wdth faint iridescent reflections ; the base of each 

 segment finely punctured ; the other })art of each segment 

 with sparing, rather large elevated points ; its pubescence 

 rather long, and much mixed with black erect setae. 

 Legs reddish. 



One specimen ; the only locality indicated being 

 " Amazons."
