Mas: abdomine segmento sexto ventrali apice leviter 

 cmarginato, segmento 7° medio triangnlariter exciso. 



Antenna' ratlier sliort, a little thickened towards the 

 extremity; ;5rd joint scarcely so long as the 2nd, 6th 

 about as long as broad, 7 — 10 transverse, 11th pointed. 

 l*alpi and parts of the mouth pitchy yellow. Head 

 broader than the thorax, its upper surface greenish-l)rassy, 

 with the hinder part tawny, the punctuation of the me- 

 tallic ])art very dense, and finer than in the other species 

 here described; the tawny ])art much more sparingly 

 punctured. Thorax about as long as broad, slightly 

 sinuate at the sides, and with the front part a little 

 broader; its upper surface very coarsely, and, with the ex- 

 ception of the usual smooth spaces, rather closely punc- 

 tured. Elytra coarsely and moderately closely punctured, 

 like the thorax of a tawny colour. Hind body narrowed 

 towards the extremity, black, with the 7th segment and 

 hind part of the 6th yellow ; 2nd segment impunctate, 

 3 — 6 rather sparingly punctured, 3 — 5 with a yellow 

 pubescence at the side parts. Legs yellow, with the 

 femora infuscate ; the sternum pitchy. 



In the male the hind body beneath has the 6th segment 

 a little emarginate at the extremity, and the 7th segment 

 has a ratlier deep and narrow triangidar notch.

PLOCIOrXERUS. 



This genus consists of six described species, and I here 

 characterize ten new ones. The five species known to 

 Erichson w^ere described by him under the generic name 

 of Staphylbnis, and it is to Kraatz that we ai-e indebted 

 for the name and some of the characters of the genus ; 

 these insects are midoubtedly most alHed to Bracliydirus, 

 but the structure of the antennae and front feet seem to 

 afford satisfactory points of distinction. 



The species are confined to tropical America, and those 

 I possess are easily referable to two sections, in one of 

 which the front tarsi and tibiaj are simple in each sex, 

 while in the other section they are more or less dilated, at 

 any rate in the males, and the hinder face of the front 

 tibia; is cut away in a peculiar manner near the exti'emity. 

 Three of the species here described were indicated as being 

 captured in fungus, which, however, they probably fre- 

 quent for predaceous purposes.
