Jensen-Haarup, New species of Coleoptera from West Argentina. 553 



Genus Tttchys. 



This genus is fairly well represented in Western Argentine. 

 The pitchy red species were mainly met with under wet dead 

 leaves, while the brighter coloured species most often were found 

 on Sandy, damp places near rivers and „lagunas". I provisionally 

 tabulate the new species as follows. 



Table of species: 



1. Elytra short oval , brownish red or pitchy brown, of a uni- 



form colour or only slightly darker towards apex . 2. 



Elytra long oval, pale yellowish or reddish yellow, with few 



dark spots or shadows 3. 



2. Head pitchy brown or black. Surface of body with a slight 



brassy reflection. Thorax and elytra pitchy brown or dark 

 reddish brown. Elytra l^/g times as long as wide, mode- 

 rately strongly punctate-striate, striae nearly disappearing 

 towards apex. Legs pale yellowish. Antennae blackish, 

 at base yellowish. Long. 2 — 2,3 mm. Prov. Mendoza ; 



not rare T. mendocinus n. sp. 



Head , as entire body , bright reddish , without any metallic 

 reflection. Elytra blackish at apex, very short (only or 

 scarcely l-^/^ times as long as wide), with strongly rounded 

 sides ; striae strongly and deeply punctate-striate , but 

 disappearing towards apex. Legs and antennae reddish- 

 yellowish , the latter not being darker towards apex. 

 Long. 1,9 — 2,2 mm. Prov. Mendoza; not common. I de- 

 dicate this short and nice , bright red species to Mr. 

 J. Jeppesen in Ranum , my first teacher in Natural 

 History T. Jeppeseni n. sp. 



3. Elytra with a common , more or less distinct , longitudinal 



sutural, dusky shadow just behind middle. Body elongate, 

 entirely pale yellow. Elytra more elongate, and thorax 

 narrower and more cordiform than in the other species. 

 Elytra elongate, at least twice as long as wide, widest 

 behind Shoulders or in front of middle, moderately strongly 

 punctate-striate ; striae of equal strength all over , also 

 at apex. Legs and antennae pale yellowish; the latter 

 sometimes brownish towards apex. Long. 2 2,2 mm. 

 Prov. Mendoza ; not very rare . T. wiivittatus n. sp. 

 Each elytron in front of middle with a semitransverse, ciinoi- 

 form, dark marking running together on suture with the 

 tip of the opposite marking, thus forming an an-le or 

 rather something like an Y-shaped figuro. Entiro body,
