98 Mr. D. Sharp's Contributions to the 



in all tlie warm and temperate parts of tlie earth's surface; 

 while in Australia there are to be found some very inte- 

 restinn; forms, apparently intenuediate between this genus 

 and Quedius. 



The four species here described belong, I think, clearly 

 to the same genus as our European species ; at any rate, 

 their facies is so similar to that of our European species 

 that any one acquainted with these would at first sight 

 declare the Amazonian sjiecies to be congeneric therewith. 

 I have several allied species from Brazil in my collection, 

 so that the genus Avill prol)ably prove to be quite as rich 

 in species in South America as in any other part of the 

 world. 



1. Aci/Iophorns pnnctiventris, n. sp. Niger, antcn- 

 narum basi, pedibusque obscure testaceis ; elytris fortius 

 punctatis ; abdomine subtiliter iridescente, segmcnto sexto 

 apice exti-emo, 7° basi apiceque testaceis, segmentis sin- 

 gulis basi crebre subtiliter, a})icem versus fortiter parcius- 

 que punctatis pubescentibusque. Long. corp. 5 lin. 



Considerably larger than A. glahricoUis. The antennaa 

 are elongate and slender, with only the two or three apical 

 joints a little stouter. The 1st joint dusky yellowish, very 

 long, about as long as the five following; the 2nd and 3rd 

 joints about eqiial in length ; 4th joint considerably shorter 

 than the 3rd and a little shorter than the 5th ; from the 

 5th to the 9th each a little shorter than its predecessor, all 

 of these joints elongate ; 10th joint much shorter, but as 

 long as broad ; last joint roimded, nearly as long as the 

 10th. Palpi yellowish ; mandibles elongate, slender, 

 crossed, dull yellowish. Head broadly ovate, with three 

 punctures between the eyes, the middle one the most for- 

 ward. Thoi'ax black and shining, rather broad, about 

 as long as broad, with the usual four punctures. Elytra 

 black, scarcely so long as the thorax, with the scutcllum 

 coarsely, moderately closely punctured. Hind body elon- 

 gate, a little iridescent, with a very rigid pubescence ; each 

 segment at the extreme base closely and finely punctured, 

 the rest of each sparingly and rather coarsely punctured ; 

 segments 2 — 5 with the hind margin furnished with a 

 row of very coarse seta3 projecting backwards ; the extreme 

 margin of the 6th segment, the base and apex of the 7th, 

 reddish. Legs reddish, a little infuscate. 



Ega, one ; Tapajos, two individuals.
